I realize I didn't make clear in the above reply why I was suddenly was talking about Axis rather than JWSDP. As mentioned in my original message, my ultimate goal was to write a client that can use SOAP encoding. So the strategy I used was to "Switch to some other web service client library that supports soap encoding (that I'm not aware of) that can be configured to run on JBoss AS 4.2.3 " This other library turned out to be Axis 1.x. The idea to switch to Axis 1.x was given to me in a JavaRanch suggestion as well as suggestions from Glassfish forums for how to get SOAP encoding support when running on GlassFish.
