[Xdoclet-user] @weblogic.transaction-isolation TRANSACTION_READ_COMMITTED generate empty setting.

[Tao Xie]

I have 2 EJBs coded with XDoclet 1.2.3 and their deploy target is weblogic 8.1sp2

 

TransactionLogBean - BMP bean, everything works fine, including @weblogic.transaction-isolation tag;

SSBFacadeBean - a Stateless Session bean. I got 2 troubles.

 

1) If I set @ejb.transaction tag to class-level, it doesn't work. So I have to set it method-level as a workaround.

2) Whatever I tried with @weblogic.transaction-isolation tag. xdoclet ignores the setting - TRANSACTION_READ_COMMITTED , generated weblogic-ejb-jar.xml has an empty <isolation-level> block. Of course, weblogic.ejbc complains about it.

 

Thanks in advance!
