Java Code not updating

Our application is deployed as a sar (inside sar - we have a war)and is deployed in JBoss4.0.3. Its a pure Java based application.
The issue is, when we make some changes in some java file and re-deploy it on JBoss,the new code is not reflecting at all. We have verified in all the ways -- clearing the temporary files inside JBoss,ensured that all the services are started properly... But still no result. We have verified the class files by copying from the server to our hard disk and decompiled it. It has the latest code....But,when running the application, these new changes are not refelecting

As such,the deployment is successful with no errors but latest updations are not updating..

Did anyone faced this kind of issue?Can somebody suggest me a solution or steps to be taken care?
Thanks in advance

Looks like some caching issue.
I will move this to the JBoss forum for you where you might get better answers.

IIRC, Jboss does cache a running SAR/WAR, how are you redeploying your changes? Are you replacing the entire SAR?

I just started too develop for Jboss but maybe I can help.
I run Jboss 5.0.0 in my Eclipse and to make sure the changes i made to Java classes are present, i completely clean all Deploys from the Server and deploy them again.
Sometimes i even have to do it twice to get my changes. (Could see it when i debugged into the Java Bean).
I will update to 5.0.1 soon because there are some deployment fixes for 5.0.0. (like the double deploy), but i don't know if this problem were already present in 4.0.3.

4.0.3 doesn't have the best reputation for hot deployment no

, even with 4.3 we tend to stop and start the container.
