Hi David,
Many thanks for the reply.
I am using a script that someone sent me, this is the first time I have ever
attempted to compile anything :).
<path id="classpath">
<fileset dir="${lib_dir}">
<include name="*.jar" />
</fileset>
<pathelement path="${java.class.path}" />
</path>
This is what is in the build.xml
by looking at that I am guessing that the class path isnt actually defined?
Regards
