PROBLEM with servlets ->JOnAS

Hi,

I use JOnAS 1.5 , Jetty-2.3.3 (http-server) and InstantDB

I made some entity beans and session beans, which are all tested.

Now i'm writing some servlets so i could lookup beans and write beans from my website.

This also works, but sometimes i get an error , and i don't know what to do with it....

when i try to get some beans from the database (via servlets) i sometimes get these errors

(I don't use Rollback only commit, when i write something to the database)

From http-server:

java.rmi.ServerException: RemoteException occured in server thread; nested exception is:

java.rmi.RemoteException: Container cannot register synchronization Object;

nested exception is: javax.transaction.RollbackException

...

From JOnAS:

SessionSynchroImpl.considerRequest() registerSynchronization(this): javax.transaction.RollbackException

Cannot enlist XAResource: javax.transaction.RollbackException

RMI TCP Connection(22) -134.58.42.3 select id from CompactDisc where artist=live

Exception in connectionClosed: javax.transaction.SystemException: cannot send XAend: javax.transaction.xa.XAException

Cannot enlist XAResource: javax.transaction.RollbackException

RMI TCP Connection(21) -134.58.42.3 select id, artist, title, rCompany, ePrice,type,genre,grou,dat

from CompactDisc where id=196455217732

Exception in connectionClosed: javax.transaction.SystemException: Cannot send XAend: javax.transaction.xa.XAException

EntitySynchroImpl.considerRequest() registerSynchronization(this): javax.transaction.RollbackException

...

It is for my thesis, so it is very important for me to get this solved...

Can you help me with this?

Thanks, best reagards
