Another problem related to this. All this works fine on my Mac however the project fails to deploy on a colleague's Windows machine. If I change *only* where the class files are put (eg. not into WEB-INF/dev but into the standard 'cold' location) then it deploys fine. Steps to modify project to get running on Windows: 1. Change build path source output folder from resources/WEB-INF/dev to classes/action 2. Change build.xml to use standard Seam-Gen build.xml - ie. compile task compiles to ${jar.dir}. Is anyone running the incremental deploy on Windows? If so were there any gotchas? The error is : ClassFormatError: Invalid constant pool index 63 in class file .... Weird eh? D.
