Subject RE: JunitTask and classpath
Date Fri, 23 Mar 2001 21:03:26 GMT
Just yesterday, I did exactly what you describe, using JWhich from that
Javatip.  I found a couple of things useful.

1) Try calling JWhich from inside you build.xml using a <java> task.  Use
the classpath you are using for your junit task and make the <arg> the
resource you are trying to locate.  Also play around with fork="yes|no" to
see the effect it has.

2) Embed a call to JWhich in the constructor of your test and have it try to
locate this resource.
