.Net client having problems w/SOAP Header to Axis WS

[Daniel Thune, MCSE]

I am having a problem with formatting a SOAP Header in a .Net client. The
client calls a Java Axis 1.1 based web service. In order to authenticate the
caller, the web service call is intercepted by another web service that
validates a security token in the header.

I have pasted my current SOAP message that my code sends as captured from a
trace function that I added. Below that is a sample SOAP message that the
developer of the web service provided. The second message was generated from
a Java Client that they used for testing.

From what I can see, the biggest differences in the header is that the Java
Client explicitly defines the security token as: xsi:type="xsd:s tring"
Secondarily, the Java client also specifies that the web service does not
need to understand the header
by using the following attribute: soapenv:mustUnd erstand="0"

I am looking for what to add/change in the C# code that invokes the web
service to attempt to match the SOAP message that works. The C# code is also
pasted below.

Any suggestions would be appreciated.

Thanks in advance,
