[jboss-user] [JBossCache] - how to support treecache transaction in CMT

[confuz]

Dear All,
      I used  TreeCache 1.4.0.GA and Jboss 4.0. currently need to support cache transaction in CMT. in the session bean method, the db operation will be rollbacked while cache operation won't when exception is threw.

how to support cache transaction in cmt?

Thanks for any help.

code sample in session bean

  | try{
  |         dboperation
  |         cacheoperation
  |             
  |         }catch(Exception e){
  |             sessionContext.setRollbackOnly();
  |             CCException ee = handleSQLException(e) ;
  |             throw ee;
  |         } finally {
  |             closeConnection(this.getClass().getName(), dbConn);
  |         }
  |
