This was already fixed in CVS. IBM changed things behind our backs. The latest implementation supports both variations.

---------------------------------------------------------------------
        Key: HB-240
    Summary: The net.sf.hibernate.transaction.WebSphereTransactionManagerLookup invokes a non-existant method on a JTSXA object
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: DUPLICATE

    Project: Hibernate2
   Versions:
             2.0 final

   Assignee: 
   Reporter: Tomasz Jankowski

Environment: Experienced on a Win2k machine running WebSphere Enterprise Studio/WebSphere 5.0, the code involved does NOT seem to be platform dependent but IS appServer dependent

Description:
Specifying a JNDI DataSource in hibernate.cfg.cml when running on WebSphere 5.0 will produce errors related to the transaction.manager_lookup_class. The class to specify for this property is net.sf.hibernate.transaction.WebSphereTransactionManagerLookup according to the Hibernate documentation. 

The bug is reproduced when the return statement is reached in the getTransactionManager(Properties) method of the lookup class. That statement tries to dynamically invoke a static method getTransactionManager() on the com.ibm.ejs.jts.jta.JTSXA class - the problem is that there's no such method. The fix is to call the correct method: instance().

Original code:
.
.
return (TransactionManager) clazz
        .getMethod("getTransactionManager", null)
	.invoke(null, null);
.
.


Suggested correction (tested by overloading the original):
.
.
return (TransactionManager)clazz.getDeclaredMethod("instance", null).invoke(null,null);
.
.

Thanks!
