Websphere 6.1 + Hudson + Ant

Running into a problem with an existing application. I'd like to get hundson running to do some CI but I cannot modify the Websphere settings (making changes appears to break the application that I want hudson to test against!)

So this is my current 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://22/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?

Without changing the classloarder delegation (which breaks the existing app) is there a way to update Websphere's ant library? I don't even know where it is, I tried searching for ant-lr but came up with many results.

Any help wou开发者_如何学编程ld be appreciated.

Why dont you run Hudson on a separate app server? You can even run it from the embedded servlet container directly from the war.

If you really need to run it on websphere look at the wiki. http://wiki.hudson-ci.org/display/HUDSON/IBM+WebSphere#IBMWebSphere-KnownIssues

Read http://wiki.hudson-ci.org/display/HUDSON/IBM+WebSphere. It states specifically that you must set child-first class loading on WebSphere 6.1.
