Java Client Interoperating with .NET Web Service
Hi all,
Has anybody got Java to work with the WebService
exposed through .NET remoting. I have an Class called
Author in the AuthorDetails namespace.
It has a single method with the following sig :
String getAuthorDetails(String strAuthorName)
The object is exposed at a well know URN endpoint
called URN:Author
If I use a .NET client to access the object,
everything goes fine. But when I use a java client
using Apache SOAP, then I get an exception :
--------------------------------------------------
java.lang.NullPointerException
at
org.apache.soap.transport.TransportMessage.read(TransportMessage.java:206)
at
org.apache.soap.util.net.HTTPUtils.post(HTTPUtils.java:296)
at
org.apache.soap.transport.http.SOAPHTTPConnection.send(SOAPHTTPConnection.java:208)
at
org.apache.soap.rpc.Call.invoke(Call.java:203)
at
AuthorJavaClient.invoke(AuthorJavaClient.java:97)
at
AuthorJavaClient.main(AuthorJavaClient.java:181)
-------------------------------------------------------This
is the SOAP packet that is sent by the JAVA client :
-------------------------------------------------------
POST /URN:Author HTTP/1.0
Host: localhost:9000
Content-Type: text/xml; charset=utf-8
Content-Length: 541
SOAPAction:
"http://Schemas.microsoft.com/urt/NSAssem/AuthorDetails.Author/Authordetails#getAuthorDetails"
<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope

</ns1:getAuthorDetails>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

This is the SOAP packet that is sent out by the
.NET client that seems to work fine :
-----------------------------------------------
