ConnectionWrapper is not visible from class loader
---------------------------------------------------
Key: HHH-3529
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3529
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.3.1, 3.2.6
Environment: SpringFramework 2.5.5, Hibernate 3.2.6 / 3.3.1, Tomcat 5.5, CommonJ
Timer ( http://www.myfoo.de/commonj/ )
Reporter: Vladimir Kralik
Attachments: hibernate-3.2.6_p2.patch
Hibernate/Spring libraries are in app.war/WEB-INF/lib.
Timer is configured as resources in Tomcat and his libraries are in
$CATALINA_HOME/common/lib/.
Function call from GUI works, but the same function called by timers gives this exception
:
org.springframework.transaction.CannotCreateTransactionException: Could not openHibernate
Session for transaction; nested exception is java.lang.IllegalArgumentException:
interface org.hibernate.jdbc.ConnectionWrapper is not visible from class loader
at
org.springframework.orm.hibernate3.HibernateTransactionManager.doBegin(HibernateTransactionManager.java:599)

It's the same bug as was in HHH-2215, but this is not resolved.
I think, that the problem is extracting classloader from currentThread(). This is always
not null, so the next test in method getProxyClassLoader() is always false.
I my case, timer thread lives in top class loader, but hibernate libraries are inside
application class loader.
Attached patch removes classloader extracting from currentThread(). It works for my
case.

We see the same issue when we bootstrap a classloader. Prior versions of Hibernate worked
fine. The problem appeared for us in version 3.3.1.

Hello guys, when will this get fixed? With this bug in place, no one can use Hibernate in
a managed bean without some nasty work-arounds (like setting the context classloader to
null before accessing the session)!

------------------------------------
You have to build hibernate from svn source. However, unfornately you will have to
maintain this fork of hibernate in your enterprise repository until it is fixed by
hibernate itself.
Otherwise you can try an AOP solution and change the class loader before the call to the
service, this is not an elegant solution but you don't have to maintain a hibernate
patch.

How to use this pathc? appreciate if some can can share the steps..
Download source code for hibernate.
Then
mkdir hibernate-src/
cd hibernate-src/
tar xvfz hibernate-src-X.Y.Z.tar.gz
cd hiber*
patch -p1<hibernate-3.2.6_p2.patch
A now you can build hibernate library.
That patch contains change only in one class, so you can change it directly in Eclipse (
or another IDE )
First you have to setup hibernate project in Eclipse.
Then you find class BorrowedConnectionProxy, rid off all lines in patch which starts with
dash(-) and instead that lines put there line marked with plus (+), so the result will be
public static ClassLoader getProxyClassLoader() {
return BorrowedConnectionProxy.class.getClassLoader();
}
After compilation you should replace BorrowedConnectionProxy.class in orinal
hibernate-X.Y.Z.jar.

It's the same bug as was in HHH-2215, but this is not resolved.
I think, that the problem is extracting classloader from currentThread(). This is always
not null, so the next test in method getProxyClassLoader() is always false.
I my case, timer thread lives in top class loader, but hibernate libraries are inside
application class loader.
Attached patch removes classloader extracting from currentThread(). It works for my
case.

Steve Ebersole updated HHH-3529:
--------------------------------
Assignee: Steve Ebersole
Fix Version/s: 3.5
The reason for the context classloader is that I am nervous about visibility of the
generated proxy if we use the classloader for BorrowedConnectionProvider. Specifically of
concern is that we would not be able to use this proxy (necessarily) anywhere the
Connection interface itself would be valid. Can any of y'all verify this?
This class should be going away anyway, so maybe not such a big deal.
ConnectionWrapper is not visible from class loader

Project: Hibernate Core
Issue Type: Bug

Hibernate/Spring libraries are in app.war/WEB-INF/lib.
Timer is configured as resources in Tomcat and his libraries are in
$CATALINA_HOME/common/lib/.
Function call from GUI works, but the same function called by timers gives this exception
