I have found a work-around to obviate the NPE. Nevertheless, I feel that the GAE/J SDK 1.3.1 has introduced an issue which did not exist in previous versions.
I have raised Google App Engine issue 2793 (Dev server web XML validation NPE for empty "welcome-file-list" tag) to detail the problem and my work-around. The link to this issue is: http://code.google.com/p/googleappengine/issues/detail?id=2793&can=6&sort=-id&colspec=ID%20Type%20Status%20Priority%20Stars%20Owner%20Summary%20Log%20Component -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
