, classpath, and parser.jar problems

[Ventimiglia, David]

Hi,

It seems the parser.jar used by Ant1.3 is not compatible with the one used
by BEA Weblogic 5.1.0.  Is there a way to fix this?  When I use the <ejbjar>
task, I get this error:

BEA told me weblogic.ejbc has a problem with more recent XML parsers, but
that it is fixed in Service Pack 8.  My organization cannot go to SP8,
however, so I'm wondering if there is a way to fix it right in my build
file.  The problem seems to be that ant.bat puts $ANT_HOME/lib/parser.jar
into the classpath used to run ant (this much makes sense), and that this
classpath becomes the java.class.path system property (this also makes
sense).  Though I wish it were otherwise, however, Ant seems to insist on
prepending the java.class.path to the classpath I use in the <ejbjar> task.
This causes problems.  If the java.class.path could be appended to the end,
or better yet, not included at all, that would work great.

So, my main questions are these:

1.  Does <ejbjar> automagically prepend the java.class.path property to the
classpath used to run weblogic.ejbc?
2.  If 1, then why?
3.  If 1 & 2, how can I make it stop?

Here's how I'm using <ejbjar> in my build.xml file:

  <target name="ejbs" depends="init,classes">
    <echo message="Generating EJBs"/>
    <ejbjar srcdir="${build.dir}"
            flatdestdir="true"
            descriptordir="${src.dir}">
      <weblogic destdir="${build.dir}"
                keepgeneric="no"
 
classpath="${build.dir}:${wl.home}/license:${wl.home}/classes:${wl.home}/lib
/weblogicaux.jar"
                oldCMP="true"
                suffix="-weblogic-ejb.jar"/>
      <include name="**/${includes.list}/**/*-ejb-jar.xml"/>
      <exclude name="**/*weblogic*.xml"/>
    </ejbjar> 
  </target>

This task produces the following output:

C:\staging\CommandProxy-weblogic-ejb.jar

Note the extra classpath elements that occur before "C:\staging", which is
the value of ${build.dir}.  These are coming from java.class.path.

Thanks!
