Hibernate version: 3.2.5.ga
I'm working on using Hibernate in a web application that has to deal with cross context dispatching (webapp A dispatching requests to webapp B) and callbacks (during processing in webapp B an API call is made back to webapp A). Many of these callbacks need to do persistence work using Hibernate DAOs.
The interesting bit of the stack trace is:
Code:
Caused by: java.lang.IllegalArgumentException: interface org.hibernate.jdbc.ConnectionWrapper is not visible from class loader

Doing some searching it looks like I'm running into this issue:
http://opensource.atlassian.com/project ... e/HHH-2281I see that BorrowedConnectionProxy tries to use the thread context ClassLoader first:
Code:
/**
* Determines the appropriate class loader to which the generated proxy
* should be scoped.
*
* @return The class loader appropriate for proxy construction.
*/
public static ClassLoader getProxyClassLoader() {
ClassLoader cl = Thread.currentThread().getContextClassLoader();
if ( cl == null ) {
cl = BorrowedConnectionProxy.class.getClassLoader();
}
return cl;
}
Is there any way to get Hibernate to use BorrowedConnectionProxy.class.getClassLoader() first instead?
