TreeCache and Hibernate

[realnode]

Hello ,

I am using treeCache for hibernate. For that i have a jtaTransactionManager usign jotm for userTransaction .

The problem is that i have problems with lazy loading and TreeCache when a lock timeout occurrs.

It's not possible to use lazy hibernate objects and TreeCache correctly? Seems that once the error occurs subsecuent calls goes bad.

Thank you for reading me.

You can probably get better advices on Hibernate forums.
