Subject RE: Deserialization error upgrading from Beta 1 => Beta 2
Date Wed, 01 May 2002 17:42:02 GMT
Upon looking into it further, it looks like Axis Beta 2 is unable to handle
HREFs where SOAP-ENC:root is not supplied. From the Axis client,
SOAP-ENC:root is set to "0" on the attached bean. However, .NET is not
including SOAP-ENC:root attributes. So the method call in the first body
element is succeeding, but then RPCProvider is attempting to execute the
attached bean as a method call, since bodyEl.isRoot() returns true for the
attached bean with no SOAP-ENC:root. Since the root attribute is not
required by the SOAP spec, shouldn't Axis be better handling those body
elements that are not root elements but have the tag omitted?
