Hi;
I'm using JBOSS 2.4, Tomcate 3.2.3,MySql 3.23.42 (with BDB for
transaction-safe supoprt), Jdk1.3.1, and mm.mysql.jdbc 1.2 driver. all
installed on a Linux box.
I'm able to deply (hot-deploy) my (BMP) entity bean and access it (via a
servlet) just fine with no problems. However, when I attempt to perform
hot-deployment (for my entity bean)at the same time there are active bean
instances (of the same entity bean being hot-deployed), belonging to to
multi-threaded client http-servlet based requests, that are accessing (i.e.
performing SQL updates), or trying to access the database; all those beans
active instances through expections.
Every time I re-attempt the test, I get a different exception raised from
the bean. The exception I've seen so far are:
- EJBException
- IllegalStateException
- RemoteException
- TransactionRolledBackException
- MarshalException: invalid remote object
- UndeclaredThrowableException
Initially I thuoght that it was a MySql, or an mm jdbc driver problem.
However, MySql (or even the mm jdbc driver)has no problems handling parallel
db transactions in any shape. Only when HotDeploy is done for the same (BMP)
entity bean type that at the same time is beeing used by clients,
creates/raises exceptions and causes all db transactions that are taking
place at that same hot-deployment time to fail.
Did I stumple upon a JBOSS bug?... Have someone else encountered this
problem?
Any help/clues will be greatly appreciated.
Regards;
Tom
PS: Below are the command line outputs of JBOSS during one of my testings
