I want to know if anyone has experience of deploying EJBs in exploded mode, especially on Weblogic 6.1.

I had this problem:
I modified the ejb-jar.xml of my Entity Bean and changed the EJB-QL query of its finder method but as I modified the REDEPLOY file and saved it (so the Weblogic 6.1 server redeployed my EJB, my EJB component was in exploded format), the result of the finder method was the same as before, and it did not consider the changes in the ejb-jar.xml file, I tried it a lot.
And when I added a new finder method to my Entity Bean, and tried to redeploy it, It threw a NullPointerException, I restart the server but there was still that Exception while deploying my Entity Bean.
But when I deployed that Entity Bean using the integrated tool of JBuilder for deploying on Weblogic 6.1 Server (so it made the jar file), There was no Exception.
