Hello,
Trying to start up Hudson3 war which is installed on WAS 7.0.0.25. I'm seeing the following error message:
"We detected that your servlet container is loading an older version of Ant by itself, thereby preventing Hudson from loading its own newer copy. (Ant classes are loaded from bundleresource://64/org/apache/tools/ant/types/FileSet.class)
Perhaps can you override Ant in your container by copying one from Hudson's WEB-INF/lib, or can you set up the classloader delegation to child-first so that Hudson sees its own copy first?"
Previous searches have pointed out that setting the classloader to child-first will resolve this, at least for WAS6. This does not work for me with WAS7.
Has anyone else run into this that may have discovered another solution? I don't manage the WAS environment, and am not entirely sure how to get at the Ant classes.
Thanks,
-Keith

Hi Pankaj,
I was able to resolve this by having Hudson reference it's Ant jars in a sharedLib. The Websphere server was grabbing old Ant jars from somewhere, but not of my WAS support people could find them, so having the sharedLib with the jars I wanted and child first (or Parent-last, if you prefer) solved the problem.
