NoClassDefFound when a service bean interface is in an outside .jar
-------------------------------------------------------------------
Key: JBSEAM-2485
URL: http://jira.jboss.com/jira/browse/JBSEAM-2485
Project: JBoss Seam
Issue Type: Bug
Affects Versions: 2.0.1.CR1, 2.0.0.GA
Environment: JBoss AS 4.2.2, 4.2.1, Seam 2.0.0.GA, 2.0.1.CR1
Reporter: Adam Warski
My deployment is as follows:
- MyApi.jar, which contains the local an interface for a stateless session bean
- MyApp.ear, which is a normal Seam application, and has an implementation of the
interface
The api is in a separate jar so that I can use the SLSB in other applications.
On some occasions, I got weird exceptions, like:
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/intercept/Proxy
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
or
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/Instance
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
(full example stack trace below).
I think the reason is as follows:
in org.jboss.seam.Component.createProxyFactory(...) - lines 2234-2254, a set of interfaces
is created. It is a HashSet, so the first element may differ on each invocation of the
method (that's why the exception is thrown only sometimes).
This set contains both the business interfaces, as well as org/jboss/seam/Instance,
org/jboss/seam/intercept/Proxy.
Then, in org.jboss.seam.util.ProxyFactory.getClassLoader (lines 196-212) (which is invoked
from the previously mentioned method), a classloader is obtained, which is later used to
load all the interfaces classes and instantiate the proxy (in javassist). The classloader
is taken to be the classloader of the first interface in the interfaces array (which is
constructed from the set).
So, the classloader may be that of:
(1) the business interface
(2) org/jboss/seam/Instance, org/jboss/seam/intercept/Proxy.
If it is number (2), then it is the scoped classloader of the ear. However, if it is (1),
then it is the unified class loader which was used to load the .jar, which contains the
business interface. This classloader cannot load the org/jboss/seam/intercept/Proxy and
org/jboss/seam/Component interfaces, as they are contained in a scoped deployment. Thus,
an exception is thrown.
A fix which I have right now is, in org.jboss.seam.Component.createProxyFactory:
1. replace HashSet with LinkedHashSet - then the first element will always be the same
2. move adding the org/jboss/seam/intercept/Proxy and org/jboss/seam/Component interfaces
to the top, so that the scoped class loader is later obtained in
org.jboss.seam.util.ProxyFactory.getClassLoader.
I've tested it and it seems to fix the issue.
And finally the promised stack trace:

Fix For: 2.0.2.GA
My deployment is as follows:

- MyApp.ear, which is a normal Seam application, and has an implementation of the

The api is in a separate jar so that I can use the SLSB in other applications.
On some occasions, I got weird exceptions, like:
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:

or
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/Instance

(full example stack trace below).
I think the reason is as follows:
in org.jboss.seam.Component.createProxyFactory(...) - lines 2234-2254, a set of
interfaces is created. It is a HashSet, so the first element may differ on each invocation
of the method (that's why the exception is thrown only sometimes).
This set contains both the business interfaces, as well as org/jboss/seam/Instance,
org/jboss/seam/intercept/Proxy.

So, the classloader may be that of:

If it is number (2), then it is the scoped classloader of the ear. However, if it is (1),
then it is the unified class loader which was used to load the .jar, which contains the

2. move adding the org/jboss/seam/intercept/Proxy and org/jboss/seam/Component
interfaces to the top, so that the scoped class loader is later obtained in
org.jboss.seam.util.ProxyFactory.getClassLoader.
I've tested it and it seems to fix the issue.

New subject: [jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-2485) NoClassDefFound when a service bean interface is in an outside .jar
[ http://jira.jboss.com/jira/browse/JBSEAM-2485?page=all ]
Adam Warski updated JBSEAM-2485:
--------------------------------
Fix Version/s: (was: 2.0.2.GA)
NoClassDefFound when a service bean interface is in an outside .jar
-------------------------------------------------------------------
Key: JBSEAM-2485
URL: http://jira.jboss.com/jira/browse/JBSEAM-2485
Project: JBoss Seam
Issue Type: Bug
Affects Versions: 2.0.1.CR1, 2.0.0.GA
Environment: JBoss AS 4.2.2, 4.2.1, Seam 2.0.0.GA, 2.0.1.CR1
Reporter: Adam Warski
My deployment is as follows:
- MyApi.jar, which contains the local an interface for a stateless session bean
- MyApp.ear, which is a normal Seam application, and has an implementation of the
interface
The api is in a separate jar so that I can use the SLSB in other applications.
On some occasions, I got weird exceptions, like:
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/intercept/Proxy
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
or
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/Instance
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
(full example stack trace below).
I think the reason is as follows:
in org.jboss.seam.Component.createProxyFactory(...) - lines 2234-2254, a set of
interfaces is created. It is a HashSet, so the first element may differ on each invocation
of the method (that's why the exception is thrown only sometimes).
This set contains both the business interfaces, as well as org/jboss/seam/Instance,
org/jboss/seam/intercept/Proxy.
Then, in org.jboss.seam.util.ProxyFactory.getClassLoader (lines 196-212) (which is
invoked from the previously mentioned method), a classloader is obtained, which is later
used to load all the interfaces classes and instantiate the proxy (in javassist). The
classloader is taken to be the classloader of the first interface in the interfaces array
(which is constructed from the set).
So, the classloader may be that of:
(1) the business interface
(2) org/jboss/seam/Instance, org/jboss/seam/intercept/Proxy.
If it is number (2), then it is the scoped classloader of the ear. However, if it is (1),
then it is the unified class loader which was used to load the .jar, which contains the
business interface. This classloader cannot load the org/jboss/seam/intercept/Proxy and
org/jboss/seam/Component interfaces, as they are contained in a scoped deployment. Thus,
an exception is thrown.
A fix which I have right now is, in org.jboss.seam.Component.createProxyFactory:
1. replace HashSet with LinkedHashSet - then the first element will always be the same
2. move adding the org/jboss/seam/intercept/Proxy and org/jboss/seam/Component
interfaces to the top, so that the scoped class loader is later obtained in
org.jboss.seam.util.ProxyFactory.getClassLoader.
I've tested it and it seems to fix the issue.
And finally the promised stack trace:

The api is in a separate jar so that I can use the SLSB in other applications.

(full example stack trace below).

New subject: [jbossseam-issues] [JBoss JIRA] Updated: (JBSEAM-2485) NoClassDefFound when a service bean interface is in an outside .jar
[ http://jira.jboss.com/jira/browse/JBSEAM-2485?page=all ]
Norman Richards updated JBSEAM-2485:
------------------------------------
Fix Version/s: 2.1.0.GA
(was: 2.1.0.A1)
NoClassDefFound when a service bean interface is in an outside .jar
-------------------------------------------------------------------
Key: JBSEAM-2485
URL: http://jira.jboss.com/jira/browse/JBSEAM-2485
Project: JBoss Seam
Issue Type: Bug
Components: EJB3
Affects Versions: 2.0.1.CR1, 2.0.0.GA
Environment: JBoss AS 4.2.2, 4.2.1, Seam 2.0.0.GA, 2.0.1.CR1
Reporter: Adam Warski
Fix For: 2.1.0.GA
My deployment is as follows:
- MyApi.jar, which contains the local an interface for a stateless session bean
- MyApp.ear, which is a normal Seam application, and has an implementation of the
interface
The api is in a separate jar so that I can use the SLSB in other applications.
On some occasions, I got weird exceptions, like:
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/intercept/Proxy
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
or
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/Instance
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
(full example stack trace below).
I think the reason is as follows:
in org.jboss.seam.Component.createProxyFactory(...) - lines 2234-2254, a set of
interfaces is created. It is a HashSet, so the first element may differ on each invocation
of the method (that's why the exception is thrown only sometimes).
This set contains both the business interfaces, as well as org/jboss/seam/Instance,
org/jboss/seam/intercept/Proxy.
Then, in org.jboss.seam.util.ProxyFactory.getClassLoader (lines 196-212) (which is
invoked from the previously mentioned method), a classloader is obtained, which is later
used to load all the interfaces classes and instantiate the proxy (in javassist). The
classloader is taken to be the classloader of the first interface in the interfaces array
(which is constructed from the set).
So, the classloader may be that of:
(1) the business interface
(2) org/jboss/seam/Instance, org/jboss/seam/intercept/Proxy.
If it is number (2), then it is the scoped classloader of the ear. However, if it is (1),
then it is the unified class loader which was used to load the .jar, which contains the
business interface. This classloader cannot load the org/jboss/seam/intercept/Proxy and
org/jboss/seam/Component interfaces, as they are contained in a scoped deployment. Thus,
an exception is thrown.
A fix which I have right now is, in org.jboss.seam.Component.createProxyFactory:
1. replace HashSet with LinkedHashSet - then the first element will always be the same
2. move adding the org/jboss/seam/intercept/Proxy and org/jboss/seam/Component
interfaces to the top, so that the scoped class loader is later obtained in
org.jboss.seam.util.ProxyFactory.getClassLoader.
I've tested it and it seems to fix the issue.
And finally the promised stack trace:

--------------------------------------
I had the same scenario / problem with Seam-2.0.0.GA. Found this issue and so upgraded to
Seam-2.1.0.A1. However, I'm afraid that the problem persists, albeit with a different
class that cannot be found...

Key: JBSEAM-2485
URL: http://jira.jboss.com/jira/browse/JBSEAM-2485
Project: Seam
Issue Type: Bug
Components: EJB3
Affects Versions: 2.0.1.CR1, 2.0.0.GA
Environment: JBoss AS 4.2.2, 4.2.1, Seam 2.0.0.GA, 2.0.1.CR1
Reporter: Adam Warski
Fix For: 2.1.0.GA
My deployment is as follows:
- MyApi.jar, which contains the local an interface for a stateless session bean
- MyApp.ear, which is a normal Seam application, and has an implementation of the
interface
The api is in a separate jar so that I can use the SLSB in other applications.
On some occasions, I got weird exceptions, like:
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/intercept/Proxy
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
or
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/Instance
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
(full example stack trace below).
I think the reason is as follows:
in org.jboss.seam.Component.createProxyFactory(...) - lines 2234-2254, a set of
interfaces is created. It is a HashSet, so the first element may differ on each invocation
of the method (that's why the exception is thrown only sometimes).
This set contains both the business interfaces, as well as org/jboss/seam/Instance,
org/jboss/seam/intercept/Proxy.
Then, in org.jboss.seam.util.ProxyFactory.getClassLoader (lines 196-212) (which is
invoked from the previously mentioned method), a classloader is obtained, which is later
used to load all the interfaces classes and instantiate the proxy (in javassist). The
classloader is taken to be the classloader of the first interface in the interfaces array
(which is constructed from the set).
So, the classloader may be that of:
(1) the business interface
(2) org/jboss/seam/Instance, org/jboss/seam/intercept/Proxy.
If it is number (2), then it is the scoped classloader of the ear. However, if it is (1),
then it is the unified class loader which was used to load the .jar, which contains the
business interface. This classloader cannot load the org/jboss/seam/intercept/Proxy and
org/jboss/seam/Component interfaces, as they are contained in a scoped deployment. Thus,
an exception is thrown.
A fix which I have right now is, in org.jboss.seam.Component.createProxyFactory:
1. replace HashSet with LinkedHashSet - then the first element will always be the same
2. move adding the org/jboss/seam/intercept/Proxy and org/jboss/seam/Component
interfaces to the top, so that the scoped class loader is later obtained in
org.jboss.seam.util.ProxyFactory.getClassLoader.
I've tested it and it seems to fix the issue.
And finally the promised stack trace:

The api is in a separate jar so that I can use the SLSB in other applications.

I think the reason is as follows:

of the method (that's why the exception is thrown only sometimes).

If it is number (2), then it is the scoped classloader of the ear. However, if it is (1),
then it is the unified class loader which was used to load the .jar, which contains the
business interface. This classloader cannot load the org/jboss/seam/intercept/Proxy and
org/jboss/seam/Component interfaces, as they are contained in a scoped deployment. Thus,
an exception is thrown.
A fix which I have right now is, in org.jboss.seam.Component.createProxyFactory:
1. replace HashSet with LinkedHashSet - then the first element will always be the same
2. move adding the org/jboss/seam/intercept/Proxy and org/jboss/seam/Component
interfaces to the top, so that the scoped class loader is later obtained in
org.jboss.seam.util.ProxyFactory.getClassLoader.
I've tested it and it seems to fix the issue.

Project: Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0.GA, 2.0.1.CR1
Environment: JBoss AS 4.2.2, 4.2.1, Seam 2.0.0.GA, 2.0.1.CR1
Reporter: Adam Warski

Fix For: 2.1.0.BETA1
My deployment is as follows:
- MyApi.jar, which contains the local an interface for a stateless session bean
- MyApp.ear, which is a normal Seam application, and has an implementation of the
interface
The api is in a separate jar so that I can use the SLSB in other applications.
On some occasions, I got weird exceptions, like:
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/intercept/Proxy
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
or
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/Instance
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
(full example stack trace below).
I think the reason is as follows:
in org.jboss.seam.Component.createProxyFactory(...) - lines 2234-2254, a set of
interfaces is created. It is a HashSet, so the first element may differ on each invocation
of the method (that's why the exception is thrown only sometimes).
This set contains both the business interfaces, as well as org/jboss/seam/Instance,
org/jboss/seam/intercept/Proxy.
Then, in org.jboss.seam.util.ProxyFactory.getClassLoader (lines 196-212) (which is
invoked from the previously mentioned method), a classloader is obtained, which is later
used to load all the interfaces classes and instantiate the proxy (in javassist). The
classloader is taken to be the classloader of the first interface in the interfaces array
(which is constructed from the set).
So, the classloader may be that of:
(1) the business interface
(2) org/jboss/seam/Instance, org/jboss/seam/intercept/Proxy.
If it is number (2), then it is the scoped classloader of the ear. However, if it is (1),
then it is the unified class loader which was used to load the .jar, which contains the
business interface. This classloader cannot load the org/jboss/seam/intercept/Proxy and
org/jboss/seam/Component interfaces, as they are contained in a scoped deployment. Thus,
an exception is thrown.

1. replace HashSet with LinkedHashSet - then the first element will always be the same
2. move adding the org/jboss/seam/intercept/Proxy and org/jboss/seam/Component
interfaces to the top, so that the scoped class loader is later obtained in
org.jboss.seam.util.ProxyFactory.getClassLoader.

[
https://jira.jboss.org/jira/browse/JBSEAM-2485?page=com.atlassian.jira.pl...
]
Andre Rodrigues commented on JBSEAM-2485:
-----------------------------------------
This problem is still happening to me.
I have all my backing beans in the web application (java bean components). My business
logic is inside EJBs in a module which has no reference to Seam whatsoever. So, the EAR
class loader has no reference to Seam classes, Seam's jar are only in my web
application (WEB-INF/lib).
After some debugging, I saw that seam (2.0.2.SP1) passes an Array of interfaces to the
ProxyFactory class. ProxyFactory gets the ClassLoader from the first class in the array.
When the first class in the array is either Proxy or Instance, everything works fine. When
the EJB interface is the first element on the array (happens after a few restarts of
JBoss), ProxyFactory gets its ClassLoader, the EAR ClassLoader, which, as metioned before,
doesn't "know" about Seam.
I think a simple solution would be change the method createProxyFactory in the Component
class to the following:
Set<Class> interfaces = new TreeSet<Class>(); // instead of a HashSet, to
guarantee the order of the elements
// so these classes the first elements on the array
interfaces.add(Instance.class);
interfaces.add(Proxy.class);
if ( type.isSessionBean() )
{
interfaces.addAll(businessInterfaces);
}
else
{
interfaces.add(HttpSessionActivationListener.class);
interfaces.add(Mutable.class);
}
ProxyFactory factory = new ProxyFactory();
// excluding this part, which was included in 2.1.0, but didn't really solved the
problem
/*{
@Override
protected ClassLoader getClassLoader()
{
return beanClass.getClassLoader();
}
};*/

NoClassDefFound when a service bean interface is in an outside .jar
-------------------------------------------------------------------
Key: JBSEAM-2485
URL: https://jira.jboss.org/jira/browse/JBSEAM-2485
Project: Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0.GA, 2.0.1.CR1
Environment: JBoss AS 4.2.2, 4.2.1, Seam 2.0.0.GA, 2.0.1.CR1
Reporter: Adam Warski
Assignee: Pete Muir
Fix For: 2.1.0.BETA1
My deployment is as follows:
- MyApi.jar, which contains the local an interface for a stateless session bean
- MyApp.ear, which is a normal Seam application, and has an implementation of the
interface
The api is in a separate jar so that I can use the SLSB in other applications.
On some occasions, I got weird exceptions, like:
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/intercept/Proxy
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
or
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/Instance
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
(full example stack trace below).
I think the reason is as follows:
in org.jboss.seam.Component.createProxyFactory(...) - lines 2234-2254, a set of
interfaces is created. It is a HashSet, so the first element may differ on each invocation
of the method (that's why the exception is thrown only sometimes).
This set contains both the business interfaces, as well as org/jboss/seam/Instance,
org/jboss/seam/intercept/Proxy.
Then, in org.jboss.seam.util.ProxyFactory.getClassLoader (lines 196-212) (which is
invoked from the previously mentioned method), a classloader is obtained, which is later
used to load all the interfaces classes and instantiate the proxy (in javassist). The
classloader is taken to be the classloader of the first interface in the interfaces array
(which is constructed from the set).
So, the classloader may be that of:
(1) the business interface
(2) org/jboss/seam/Instance, org/jboss/seam/intercept/Proxy.
If it is number (2), then it is the scoped classloader of the ear. However, if it is (1),
then it is the unified class loader which was used to load the .jar, which contains the
business interface. This classloader cannot load the org/jboss/seam/intercept/Proxy and
org/jboss/seam/Component interfaces, as they are contained in a scoped deployment. Thus,
an exception is thrown.
A fix which I have right now is, in org.jboss.seam.Component.createProxyFactory:
1. replace HashSet with LinkedHashSet - then the first element will always be the same
2. move adding the org/jboss/seam/intercept/Proxy and org/jboss/seam/Component
interfaces to the top, so that the scoped class loader is later obtained in
org.jboss.seam.util.ProxyFactory.getClassLoader.
I've tested it and it seems to fix the issue.
And finally the promised stack trace:

-----------------------------------------
OK, sorry for that :-)
The new issue is at: https://jira.jboss.org/jira/browse/JBSEAM-3758
NoClassDefFound when a service bean interface is in an outside .jar
-------------------------------------------------------------------
Key: JBSEAM-2485
URL: https://jira.jboss.org/jira/browse/JBSEAM-2485
Project: Seam
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0.GA, 2.0.1.CR1
Environment: JBoss AS 4.2.2, 4.2.1, Seam 2.0.0.GA, 2.0.1.CR1
Reporter: Adam Warski
Assignee: Pete Muir
Fix For: 2.1.0.BETA1
My deployment is as follows:
- MyApi.jar, which contains the local an interface for a stateless session bean
- MyApp.ear, which is a normal Seam application, and has an implementation of the
interface
The api is in a separate jar so that I can use the SLSB in other applications.
On some occasions, I got weird exceptions, like:
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/intercept/Proxy
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
or
Caused by: java.lang.RuntimeException: by java.lang.NoClassDefFoundError:
org/jboss/seam/Instance
at org.jboss.seam.util.ProxyFactory.createClass(ProxyFactory.java:190)
(full example stack trace below).
I think the reason is as follows:
in org.jboss.seam.Component.createProxyFactory(...) - lines 2234-2254, a set of
interfaces is created. It is a HashSet, so the first element may differ on each invocation
of the method (that's why the exception is thrown only sometimes).
This set contains both the business interfaces, as well as org/jboss/seam/Instance,
org/jboss/seam/intercept/Proxy.
Then, in org.jboss.seam.util.ProxyFactory.getClassLoader (lines 196-212) (which is
invoked from the previously mentioned method), a classloader is obtained, which is later
used to load all the interfaces classes and instantiate the proxy (in javassist). The
classloader is taken to be the classloader of the first interface in the interfaces array
(which is constructed from the set).
So, the classloader may be that of:
(1) the business interface
(2) org/jboss/seam/Instance, org/jboss/seam/intercept/Proxy.
If it is number (2), then it is the scoped classloader of the ear. However, if it is (1),
then it is the unified class loader which was used to load the .jar, which contains the
business interface. This classloader cannot load the org/jboss/seam/intercept/Proxy and
org/jboss/seam/Component interfaces, as they are contained in a scoped deployment. Thus,
an exception is thrown.
A fix which I have right now is, in org.jboss.seam.Component.createProxyFactory:
1. replace HashSet with LinkedHashSet - then the first element will always be the same
2. move adding the org/jboss/seam/intercept/Proxy and org/jboss/seam/Component
interfaces to the top, so that the scoped class loader is later obtained in
org.jboss.seam.util.ProxyFactory.getClassLoader.
I've tested it and it seems to fix the issue.
And finally the promised stack trace:
