To deal with attachments within JBoss WS, you will need the the following files: jax-mapping.xml (maps values to the wsdl) webservices.xml web.xml your_wsdl_file.wsdl your_class_files.class The first three can be generated by wstools, altough from my personal experience, some manual tweaking is necessary.
