Precompiling JSPs Outside Weblogic Home Directory

Question

Using Weblogic Server 9.2. Was able to precompile JSPs in a war file with weblogic.appc at the command line with only the weblogic.jar inside the Weblogic installation directory in my classpath. I then translated this into an Ant task, and because the script may need to run on a box that does not have Weblogic installed, copied weblogic.jar to my build area and included that one in my classpath. It immediately began throwing NoClassDefFound exceptions. Discovered the "Class-Path" list of additional jars in the MANIFEST inside weblogic.jar, searched these jars and found all of the missing classes--except for the last one. The missing class is org/apache/bcelx/classfile/ClassParser, and the error I'm getting is "WARNING: unable to get an input stream for jar:file:D:\APPS\Java\jdk1.5.0_13\jre\lib\rt.jar!" followed by java.lang.NoClassDefFoundError. The error occurs in javelin.java.JavaClassFile.getParseTree() at line 178. There is a BCEL Apache project, but they have no mention of BCELX on their website. Anyone know where I can find this class, or source code for javelin.java.JavaClassFile?

I tried the wlappc target:
<target name="_precompile-jsp">
     <taskdef name="wlappc" classname="weblogic.ant.taskdefs.j2ee.Appc" classpathref="class.path" />
     <echo message="Precompiling JSPs in ${appfile}"/>
          <wlappc source="${appfile}" debug="true" verbosejavac="true" verbose="true" runtimeflags="-J-ms1024m -J-mx2048m"/>
</target>
But I keep getting:
[java] [wlappc] java.lang.OutOfMemoryError: Java heap space
We've got quite a lot of jsps in our application. It seems the memory options are being ignored and it seems other people have experienced the same problem with the memory options being ignored when using wlappc and have switched to weblogic.appc.
When I switch to weblogic.appc I don't get the out of memory issue, though of course I'm still getting the initial stack trace reported. Any other ideas?
