Hi Joakim, I am a colleague of Wayne's helping him with his problem. I've attached a simple ant build script and source to reproduce the problem we're having. The build script is from your stackoverflow entry that Wayne linked to. Note there is a circular dependency in that ant script as the "jspc" target depends on the "compile" target and compile is supposed to compile the servlet generated by the "jspc" target. I'm no ant expert, but that doesn't seem to be related to the problem that Wayne is having.
Thanks and any help is much appreciated!
