Hibernate only uses the first level cache by default - you have to configure the second level cache explicitly. The first level cache should not give you any problems, and since JBoss supports hot deployment you should be able to develop and deploy without restarting. How are you caching your POJOs?

Hi Paul,
tx for reply...

Im not configuring nothing special, just using standard hibernate for now, while in development. I�m using exploded directory structure do develop so I have a folder for my .ear, inside a folder for my .jar and for .war, everything works fine when i do a hot deployment and touch the application.xml , jboss does update the class loader but if i had used any data domain object(i.e - hibernate persistence objects) when i try to to run a JUnit test again I allways get an exception like this:



any help will be appreciated..

I have similar kind of issue.
I am using weblogic8.1(SP4), but whenever I modified something in code and deploy again, the server deploys old code, not the modified one.

yup, but even if I use .jar then also it is supposed to deploy at Runtime again.

One more reason I am thinking: I am using quartz, so even when I redeploy whole application the quartz thread continously running, don't get redeploy untill unless I shutdown the App Server, so that thread keeps using old java objects and never let them expire from memory through garbage collector.

So even though my APP-INF/lib folder have a new code(I have checked it), I am getting data from old objects.


Any body came across that kind of scenario?

Jignesh, using exploded directory structure you have to place a file called Redeploy under the directory Meta-inf on you .ear and touch it to get weblogic to reload the classes eliminating the need to restart it.
