Strange behavior with a distributed transaction

Hi, I have a scenario where I'm trying to run a distributed transaction across two websphere 6.1 app servers on two different nodes (2 physical machines). A stateless session bean on server 1 makes an entry to a table in the database after which it calls the remote ejb on server 2 which again mak

Entitymanager lookup using JNDI on webshpere

2009-01-07 Thread devu213
Hi, I need to lookup an entitymanager using JNDI on websphere 6.1. My persistence.xml is configured to use JPA. Although I use injection (which works) in almost all cases, I have a case where I would like the use of entitymanager in a POJO and therefore would like to get it from JNDI directly. T

Hi, I'm sorry, I looked at the log file that I attached and realized that it has gotten truncated due to some character in between (I copy pasted it from eclipse console). Here is the entire log file on a different run. Pinaki, your observation is correct but the thing is the very reason that t

Subsequent to my last post, I have tried the code on versions 1.0.2 and 1.2.0. It fails on both ( in addition to 1.1.0 on which I originally tried it). Another observation is that if I'm persisting a base class subclass hierarchy twice in two methods, like I'm doing, the first invocation fails. H

I have since realized that this problem has nothing to do with DBUnit. I was trying to test an inheritance hierarchy with openJPA and that is failing. I have added to a separate post that already mentions a similar issue with version 1.1.0 devu213 wrote: > > I'm really having prob

I too get the exact same problem. In fact, it behaves quite wierdly in my case. I have two methods doing the exact same thing i.e insert a Creditor object with different ID's. With the object hierarchy below, I expect it to fire a Customer query insert and then a creditor query insert for both

Hi, I have a very peculiar problem. I'm using JPA/openJPA in conjunction with dbUnit for unit testing. The sequence of events of course is Initialize db using dbunit API -> Do insert using openJPA -> do asserts using dbunit API. In order to have a decent performance level over what would be a s
