VB client to apache invoking EJB error
Hi:
I have got a VB client talking with Apache Server (invoking a class method)
based on the demos provided in this mailing list, I am trying to set up the
VB client invoking a EJB of the apache server(similar to the ejb example
provided by apache, but vb to apache instead of apache to apache). VB client
request has encoding style in the soap envelop section which works well with
directly invoking a class method, but will cause this error from the
StatelessEJBProvider if directly invoking a EJB. Apache client request has
the encoding style in the soap body and this works well with the
StatelessEJBProvider.
Is this a problem(bug) with the StatelessEJBProvider mechanism? or I am
missing something here?
Any feedback will be appreciated.

Here is the tcp tunnel trace of the request from VB client where you can see
the encodingStyle is in the envelop(and this is probably the reason causing
the StatelessEJBProvider to fail ?):

Here is the tcp tunnel trace sent from the apache client to invoke EJB where
you can see the encoding style is in the soap body.( and this works with the
StatelessEJBProvider)
