Loggable NoClassDefFoundError in FOP 1.20.3 and WL 6.1

["Dowd, Brian" <bd...@lehman.COM>]

HI,
    I am deploying a big EAR in WL 6.1 on solaris and I am bundling FOP
1.20.3 with it, I am
also including avalon 4.0 and logkit 1.0 jars within it as they are needed
by fop.jar.  Whenever I
try to construct a "Driver()" class I get a NoClassDefFoundError on the
org.apache.framework.logger.Loggable
interface that it needs.  The strange thing is that when I do the following
:

try {
  ClassLoader cl = this.getClass().getClassLoader();

  cl.loadClass("org.apache.avalon.framework.logger.Loggable"); //
.........this works OK

  // the following .... fails with NoClassDefFoundError on Loggable
  org.apache.fop.apps.Driver d = new org.apache.fop.apps.Driver(); 

} catch (Throwable t) {
  cat.error("failed:", t);
}

It DOES work when I put the necessary jars on the  server startup class
path, however it would obviously be
better to be able to bundle the 3rd party jars within my EAR ....... I know
this seems like it would be a general
weblogic classloader question - but I have had no problems with any other
3rd party jars that are similar to
this one.  

Has anyone else had these kinds of problems ?

Cheers,
Brian.

Brian,

I assume this is for some clandestine eavesdropping operation.
