Subject Ant 1.6 with Weblogic 8.1
Date Thu, 04 Mar 2004 15:10:25 GMT

Hi everyone,

I'm currently attempting to migrate from Ant 1.5.3 to 1.6.  
As part of my build process I need to invoke the Weblogic Server supplied
Ant task <wlappc>.  
Up to this version of Ant, I have just added the weblogic jarfile to the
classpath and added the taskdef for the weblogic tasks into the file of ant.jar.

This does not seem to work now.  If I add weblogic.jar to the classpath
(using the -lib option), I get the following error when ant tries to invoke
the launcher:

        at java.lang.Class.newInstance0(
        at java.lang.Class.newInstance(

I've tried removing weblogic.jar from the classpath and putting it in the
ant lib folder.  This got rid of the above error but it could not see the
<wlappc> task.  Even if I take the weblogic taskdefs from the file and have weblogic.jar in the classpath, I still get
the launcher exception.

Any help would be much appreciated,
