org.jboss.ws.WSException: Cannot find java method

gygerl Nov 22, 2006 11:01 AM

Hello,
I need to access a Uniface webservice (rpc) containing complex types.
Access to Uniface service without complex types was ok.
In this case, complex types are defined in different namespaces.
I get the following error :

Calling is made the following way :

InitialContext iniCtx = getInitialContext();
 SIPSVMANDANTSService service = (SIPSVMANDANTSService) iniCtx
 .lookup("java:comp/env/service/SIPSVMANDANTS");
 SIPSVMANDANTS port = service.getSIPSVMANDANTSPort();

service is defined in file ejb-jar.xml as :

<service-ref>
 <service-ref-name>service/SIPSVMANDANTS</service-ref-name>
 <service-interface>ch.ne.gubpm.ws.client.sipp.SIPSVMANDANTSService</service-interface>
 <wsdl-file>META-INF/wsdl/SIPSVMANDANTSService.wsdl</wsdl-file>
 <jaxrpc-mapping-file>META-INF/sipp/jaxrpc-mapping.xml</jaxrpc-mapping-file>
 <port-component-ref>
 <service-endpoint-interface>ch.ne.gubpm.ws.client.sipp.SIPSVMANDANTS</service-endpoint-interface>
 </port-component-ref>
 </service-ref>

Any idea of what i did wrong ?
Thanks in advance.
