Hi
I'm new to jBoss. I want to know the best approach for deploying code to a local jBoss while doing day to day development. ie change 1 jsp file, test it in my browser. Change a line of java, deploy, test. Repeat ad lib.
At the moment, the team's approach is to change one line, compile the whole project, build a full war and copy it into the deploy folder to be picked up by the hot deploy scanner. This is really slow.
What approach have people taken to deploying java code? Multiple smaller wars? Jars? Deploying the changed .class files?
Anyone know how to make jBoss read jsp files straight out of a source controlled folder?
(I got it to read js & css straight out of source control by changing the server.xml, Host -> Context -> docBase="C:/dev/web")
Thanks

Hello and happy new year,
Please excuse me for my English (i am French).
I'm new to JBoss (AS version 4.4 GA), I work on a project with EJB 3.0, and am having a problem to import a project (a simple java project) in my EJB:
My project contains an EJB module:
- DemoEJB
an WAR:
- DemoWAR
and an EAR that includes them:
-DemoEAR
I want to use a Java project that contains the example for this simple class:
public class Hello {
public String hello(){
return "Hello";
}
}
When I made it like that:
@Entity
@Table(name = "addresses")
public class Address implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int ID;
private String name;
public Address() {
}
public Address(Hello h) {
}
//...
}
I get the following error:
18:40:37,464 ERROR [URLDeploymentScanner] Incomplete Deployment listing:

before-filter? Didn't you mean parent-policy instead? Because what could be simply done is:
<?xml version="1.0" encoding="UTF-8"?>
<classloading-domain xmlns="urn:jboss:classloading-domain:1.0" name="jboss.j2ee:extension=LoaderRepository,service=EARDeployment,url='ibs.ear'" parent-domain="DefaultDomain">
<parent-policy name="AFTER_BUT_JAVA_BEFORE">
<before-filter>
<javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.plugins.filter.NegatingClassFilter">
<constructor>
<parameter>
<javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.spi.filter.RecursivePackageClassFilter">
<constructor>
<parameter>org.hibernate</parameter>
</constructor>
</javabean>
</parameter>
</constructor>
</javabean-->
</before-filter>
<after-filter>
<javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.plugins.filter.NegatingClassFilter">
<constructor>
<parameter>
<javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.spi.filter.RecursivePackageClassFilter">
<constructor>
<parameter>org.hibernate</parameter>
</constructor>
</javabean>
</parameter>
</constructor>
</javabean>
</after-filter>
</parent-policy>
</classloading-domain>
but then only parent policy is set to AFTER_BUT_JAVA_BEFORE and additional filters have no effect.
Equivalent to AFTER_BUT_JAVA_BEFORE parent policy via filters would be that already posted:
<?xml version="1.0" encoding="UTF-8"?>
<classloading-domain xmlns="urn:jboss:classloading-domain:1.0" name="jboss.j2ee:extension=LoaderRepository,service=EARDeployment,url='myapp.ear'" parent-domain="DefaultDomain">
<parent-policy>
<before-filter>
<javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.plugins.filter.JavaOnlyClassFilter" />
</before-filter>
<after-filter>
<javabean xmlns="urn:jboss:javabean:2.0" class="org.jboss.classloader.plugins.filter.EverythingClassFilter" />
</after-filter>
</parent-policy>
</classloading-domain>
but that of course doesn't work because of private constructors (and even if it would work it wouldn't be of much help when multiple filters can't be specified in each (before/after) section).
As a quick solution I've currently removed the hibernate-validator-legacy.jar from JBoss libs which got us further, but I'll try to look at some solution with combining filters. but generally I was hoping that this jboss-classloading-domain.xml approach would bring an easy solution right away - at least for this case which is probably to be used most - I believe.
And yes, I too think that parent-first is more natural, but the weirdness here is that "plain default" is false while adding classloading config turns it automatically into true. Then if you want to use filters the previous behavior changes significantly just because of that. The optimal target would be either to allow for multiple filters directly, or at least alllow change the parent-first state and let filters work over it.

Hi.
I am a support rep for an application that uses jboss as its web app. I am looking into the affect of Sha-2 ssl certifictes. Its new ssl technology that some government agencies are required to use. I have done some preliminary research on it so far, so do not know too much about it. I found some information on ms technet blog that certain os versions will not have support for this type of ssl while others will require patches. I wasn't sure if this would affect web servers and thought I would post a question here. Not sure if I am in the right location for the question. Also, I do not know too much about jboss, just enough to support my product. The versions we use are 4.0.4, 4.0.5, 5.0.1,
Thanks in advance for any info you can provide.
Jenna

Ah, another thing I missed -- EARClassLoaderDeployer. ;-(
Same issue as WebCLDeployer, it also sets some defaults, if no CLMetaData exists.
Let me check what gets used if you don't define any parent-domain in jb-cl-domain.xml.
> Also I noticed that war classloaders don't show up any parent domain (null).
How do you see this?
Didn't we fix this with explicit jb-cl.xml in each of the wars? (until WebCLDeployer is fixed)
> So do you think that NothingClassFilter combined with RecursivePackageFilter (the same way as NegatingClassFilter) would do the desired blocking?
If you use NothingFilter then there is nothing to combine. ;-)

[JBoss Web Services] - jboss6 final and jbossws 3.4.0
by Antoine Brun

"jboss6 final and jbossws 3.4.0"

--------------------------------------------------------------
Hello,
I'm currently trying to migrate our application from jboss5 to jboss6 and I'm running into some issues.
My first try was with jboss6 CR1:
We have some web services (EJB3 endpoints) and they all have @HandlerChain declaration (we use this to do the XML validation since the built-in SOAP validation didn't work on Jboss5) and it all worked fine with jboss5 and jbossws native 3.3.1 GA.
Now with jboss6 CR1, since it is shipped with jbossws-CXF 3.4.1 my @HandlerChain declaration does not seem to be valid any more (btw, I was not able to find any clear document on own to declare a handler chain with CXF).
So I've decided to use *jbossws-native-3.4.0* (the latest version available) and I worked fine: I was able to have my web services running just like with jboss5
Today, I've downloded *jboss6 Final with CXF 3.4.1*
18:32:43,489 INFO [AbstractServerConfig] JBoss Web Services - Stack CXF Server 3.4.1.GA
and just like for jboss6 CR1, I tried to deploy jbossws native.
But this time I get:
18:34:46,515 INFO [AbstractServerConfig] JBoss Web Services - Native Server 3.4.0.GA
18:34:46,523 ERROR [AbstractKernelController] Error installing to PreInstall: name=WSDescriptorDeployer state=Real: java.lang.NoClassDefFoundError: org/jboss/wsf/spi/metadata/DescriptorParser
at java.lang.Class.getDeclaredConstructors0(Native Method) [:1.6.0_23]
at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389) [:1.6.0_23]
at java.lang.Class.getDeclaredConstructors(Class.java:1836) [:1.6.0_23]
.....
Caused by: *java.lang.ClassNotFoundException: org.jboss.wsf.spi.metadata.DescriptorParser*
at java.net.URLClassLoader$1.run(URLClassLoader.java:202) [:1.6.0_23]
So, jboss6 CR1 comes with Stack CXF Server 3.4.0.CR3 and I can install Native Server 3.4.0.GA
But, jboss6 Final comes with CXF 3.4.1 and I cannot install Native Server 3.4.0.GA...
Can someone please explain me:
- *how to install jbossws native in jboss6?*
- *where do I get jbossws native 3.4.1 (is it available? 3.4.0 native or CXF are the latest available at http://www.jboss.org/jbossws/downloads http://www.jboss.org/jbossws/downloads )?*
- *how do I declare HandlerChain with CXF?*
my EJB have @HandlerChain(file = "/META-INF/soapHandler/handler-chain.xml")
and the handler-chain.xml is as follow:
<?xml version="1.0" encoding="UTF-8"?>
<handler-config>
<handler-chain>
<handler-chain-name>SoapHandler</handler-chain-name>
<handler>
<handler-name>SoapMessageValidationHandler</handler-name>
<handler-class>com.ubiqube.api.ws.soapHandler.MessageValidationSoapHandler</handler-class>
</handler>
</handler-chain>
</handler-config>
thanks,
Antoine

> I'll try something, but I'm not sure what to try exactly. Looks like adding NegatingClassFilter for org.hibernate as after-filter isn't the way so I'm not sure which way to go to block some packages/classes completely regardless their presence anywhere or not.

The same negating filter should also work for after phase.
The fully blocking filter is NothingClassFilter.
> EDIT: I tried to setup filters on org.hibernate.validator package several ways - before-filter was always NegatingClassFilter on that package, after-filter was once NegatingClassFilter, once just PackageClassFilter, also tried RecursivePackageFilter for both before-filter and after-filter in the end but to no avail.
Hmm, yeah, I think that was a typo on my end, we need RecursivePackageFilter.
But apart from that I don't see what can go wrong.
Could you debug a bit more?
Or do you have some test case / example to share?
