Access .Net Web services from java client

When i executed the simple java client program
iam getting an soapexception- Server did not recognize the value of HTTP Header SOAPAction:http://tempuri.org/action/libSearch.TestText.

.Net web service is in a different machine and the java client in a different machine , both are inside the firewall. Kindly look into the code why it is giving this problem. Iam new to java and web service.

-----------------
- Does Apache SOAP work with Microsoft SOAP?

Yes, but you need to install a patch to the MS SOAP package. One of the well-known interoperability problems between Apache 2.0 and MS Soap is that MS clients do not send type information with each parameter, and the Apache soap server will reject such requests.

James Snell has provided a patch adding the typing. It can be found at SOAP-WRC web site.

-----------------

Unfortunately, that link has gone...  hmmm....

There is this thread which may be of some use:

http://aspn.activestate.com/ASPN/Mail/Message/Apache-Soap-Users/736323

I think Apache expects the xsi:type parameter in each SOAP tag...  which MS SOAP doesn't give it...

If this IS the problem...  this page seems quite useful:

http://www.perfectxml.com/articles/xml/soapguide.asp

Anyway...not even sure this is the problem, so I'll stop typing ;-)

Good luck!!

Tim.
