Re: Websphere and Local transactions ..

Dear Madhav,

WebSphere looks like it is behaving correctly. It looks like you are 
attempting to begin a LocalTransaction from within the context of an existing 
JTA UserTransaction -- the spec forbids "transaction interleaving". You'll 
get a similar error in WebLogic. Set your EJB method transaction attribute to 
"not supported" (I don't recall the actual syntax) to prevent the container 
from invoking your EJB method from within the context of a JTA 
UserTransaction. I don't know why this worked on the J2EE RI -- make sure the 
EJB transaction attribute was the same in both environments.

see J2C 1.5 section 7.8.3

Cheers,

Tim
