JWSDP does not produce WSDL without entries in config file
It seems as if wscompile will not produce a wsdl without a config file entry for a service. It would greatly simplifiy using JWSDP if the team could just use the source code instead of the complicated service entry. Axis does a good job of this using java2wsdl ant task.
Also, it seems as if the config file does not support multiple services. You can list one service but not more than one in the config file.
