I think you might have a permissions issue. In your case seam-gen doesn't appear to overwrite existing files like ejb-jar.xml when creating a new project, although the ant task does define overwrite explicitly. Those files are created initially by eclipse WTP, but we want to overwrite them with the seam-gen versions. Maybe eclipse is generating the files under a different user, or not providing "rwx" to the files that that seam-gen is trying to overwrite.
