When debugging JSP pages on WebLogic the CSF.getSourcePath() returns for example jsp_servlet/_mypath/index.jsp (this is the way how WL compiles it) so the SourcePath.showSource() will never find correct mypath/index.jsp.

It might be doable by SourcePathProvider, but it looks like it would be duplicate of SourcePathProviderImpl of projects integration. In fact this is just simple name translation so some small SPI could help I guess.

The important part of my HACKED solution looks like this:

   11.40 +        // XXX terrible hack - in addition WL specific code
   11.41 +        if (relativePath.startsWith("jsp_servlet")) { // NOI18N
   11.42 +            SourcePathProvider provider = getDefaultContext();
   11.43 +            if (provider != null) {
   11.44 +                String path = relativePath.substring(11);
   11.45 +                path = path.replaceAll("/_", "/"); // NOI8N
   11.46 +                if (path.startsWith("/")) {
   11.47 +                    path = path.substring(1);
   11.48 +                }
   11.49 +                return provider.getURL(path, global);
   11.50 +            }
   11.51 +        }
