WebServices NullPointerException when Client tried to get SOAP

[Sam Sunamin]

Hi Web Services Guru,

We have web services server deployed on windows 2003, Application server is IIS 6.0 using .net.

Now we need web services client to consume this web services using Java running on WebSphere 6.1 on AIX box.

Now the client get exception when it tries to get SOAP message.

Inside setHeader(), exception through out from here.
javax.xml.rpc.Stub stub= (javax.xml.rpc.Stub) proxy.getProspectWSSoap();

which is from
__prospectWSSoap = ((com.Scotiabank.ProspectWS)ctx.lookup("java:comp/env/service/ProspectWS")).getProspectWSSoap();

I am not sure what else I need to config to make it work?

  java.lang.NullPointerException
