ApacheSOAP2-2 and Weblogic6.1

[Mukesh Bablani <mu...@ezcommerceinc.com>]

Hi
	I am trying to deploy a simple EJB running in WLServer6.1 as a Web
Service. I am using Apache SOAP2.2 kit for the same, which is working
properly for simple Java Classes hosted as Web Service.
	When I run the client which accesses a simple EJB I get the
following exception

Exception in thread "main" [SOAPException: faultCode=SOAP-ENV:Client; msg=A
'http://schemas.xmlsoap.org/soap/envelope/:F
ault' element must contain a: 'faultcode' element.;
targetException=java.lang.IllegalArgumentException: A 'http://schema
s.xmlsoap.org/soap/envelope/:Fault' element must contain a: 'faultcode'
element.]
        at org.apache.soap.rpc.Call.invoke(Call.java:246)
        at samples.weblogic_ejb.ejbtest.main(ejbtest.java:122)


THE FOLLOWING IS SOAP message as sent from client side

POST /soap/servlet/rpcrouter HTTP/1.0 Host: localhost Content-Type:
text/xml; charset=utf-8 Content-Length: 443 SOAPAction: ""  <?xml
version='1.0' encoding='UTF-8'?> <SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/1999/XMLSchema"> <SOAP-ENV:Body> <ns1:hello
xmlns:ns1="urn:ejbhello"
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"> <symbol
xsi:type="xsd:string">myhello</symbol> </ns1:hello> </SOAP-ENV:Body>
</SOAP-ENV:Envelope> 


The next is the SOAP return
