Weird Rollback Exception

[yeroc]

Hi,

I'm running into a strange problem when calling a method on a stateless session bean which is retrieving some data from a database (Oracle). The method itself appears to run fine but I'm getting the following stacktrace from jboss (2.4.9) seemingly as the method returns (see below). The strange thing is the embedded exception itself is null so I really have no idea what's going wrong here. I have similar methods on the same stateless session bean that are running fine...Any ideas?

Thanks,
Corey

Stacktrace:

Your bean is throwing a null pointer exception.
Try wrapping the method in a

try
{
...
}
catch (Exception e)
{
e.printStackTrace();
throw new EJBException(e);
}
