2006-05-30 Thread drabbit
I've had this exception too, but probably in a different setup than you have. 
We were using mvc from persistance soft to enable ejb2.1 in jboss 2.4.x (also 
worked with later jboss version). This persistance mechanism had the default 
behaviour to only set Transaction to rollbackonly and NOT throw an EJBException 
when the commit on the database transaction fails. Then at a later time (the 
spot where your exception originates from) the transaction is rolled back 
(because it is set to rollbackonly) but the original error message from the 
database is lost. When changing the default behaviour to not only roll back the 
Server Transaction, but to also throw an EJBException, the message of the 
database is exception is not lost but can still be found at the end of a big 
nested exception chain within the TransactionRolledBackException.

You might have a different system setup, but maybe this explanation what 
happened to us helps you find your problem.

Basically, the Server Transaction was set to rollbackonly at a certain point 
without throwing an exception there.

I don't fully understand what you are doing, but concerning the necessity to 
have it all in one transaction:
if your datasources are configured in *-ds.xml files and obtained via jndi 
lookup, then this will all happen in one server transaction. If you are using 
different datasources, all but one need to be xa-enabled. If you get your 
datasource via jndi lookup and specify the same datasource as your EJB 
persistance datasource, then you will get the same database connection so you 
won't have to worry about xa.

It's neither a bug in java or jboss, you shouldn't alternate a collection while 
running over it with an iterator.

2006-05-22 Thread drabbit
This is an interesting question, but I doubt there is a solution to it. You 
might want to go one step back and post what you need to know this information 
for. If it is merely for logging and to check if calls are local or remote, you 
could just write an interceptor that logs the invocation type.

methodC should run in a separate transaction and commit upon completion.

Your post doesn't show how you called methodB and methodC, so let me make sure: 
Did you call those methods over the local interface or just inside the bean 
implementation? The new Transaction is of course only started if the invocation 
passes the interceptor stack.

I'd check if there are some constraints on your database that doesn't let the 
server save the data. Like uniqueness constraints of not-null constraints.

[JBoss-user] [EJB/JBoss] - Question on Invocation Payload

2006-05-03 Thread drabbit
Hi,

I'm using jboss 4.0.2 and in an attempt to measure the time needed for rmi 
calls and serialization, I implemented a client side and a server side 
interceptor that would put different timestamps as Long values into the 
invocation payload (AS_IS). What happened is that the payload set on the client 
would reach the server, but on the way back the payload set on the server would 
not reach the client again. Is this behaviour intended or is there most likely 
a bug in my implementation?

thanks for any help and hints,
  Dirk
