Hi i have problem deploying EJB, i wonder if someone can help.

Iam using Weblogic 7 SP 1, after i have compiled and built my project, i go to
deploy it and i get the following error message !! I have tried increasing memory
allocated to EJBC to 512Mb, but this made no difference.

--------------------------------------------------------------------------------
        <java classname="weblogic.ejbc" fork="true" failonerror="yes">
            <classpath refid="classpath"/>
          <!--INCREASED MEMORY ALLOCATED HERE -->
            <arg line="-J-mx512M"/>  
            <arg value="${build.classes}\ejb-temp.jar"/>
            <arg value="${dist.dir}\ejb.jar"/>
        </java>
--------------------------------------------------------------------------------

Below is the error message i get.

Can someone please advise as to what the
problem might be, and how i can resolve it !!!

Thanks

Here is what BEA says about this:

Due to a Sun bug, a java lang.OutOfMemory error my occur when starting WebLogic Server if the number of classes being loaded is too high.

As a workaround, increase the value of the JVM option -XXMaxPermSize when initializing WebLogic Server, using this syntax:

java -XX:MaxPermSize=<value>K

where <value> is some number of kilobytes. The JVM uses a default maximum value of 32 MB.

This problem has been reported to Sun.

Hope this helps you
