SOAP & entity EJBs

[Peter Ondrus]

Hello,
we have an entity EJB on the server, and we neet to do SOAP RPC calls to 
it. It seems that everithing works fine on server side, but when I call 
findByPrimaryKey method, it seems, that I have some problems with 
serialization/deserialization of returned interface from 
findByPrimaryKey method. Is it necessary to write my own 
serializer/deserializer, or 
org.apache.soap.encoding.soapenc.BeanSerializer should be enough? I do 
not know where else could be a problem.
Here is my DD and code of client:

Deployment descriptor:
<?xml version="1.0"?>

<isd:service xmlns:isd="http://xml.apache.org/xml-soap/deployment";
             id="urn:ejbsoaptest">
  <isd:provider type="org.apache.soap.providers.EntityEJBProvider"
                scope="Application"
                methods="getValue setValue">
    <isd:java class="humantec.SoapTestEntity"/>
    <isd:option key="FullHomeInterfaceName" 
value="sk.humantec.hcs.ma.server.soap.TestEntityHome" />
    <isd:option key="ContextProviderURL" value="jnp://localhost:1099" />
    <isd:option key="FullContextFactoryName" 
value="org.jnp.interfaces.NamingContextFactory" />
  </isd:provider>
        
<isd:faultListener>org.apache.soap.server.DOMFaultListener</isd:faultListener>
  <isd:mappings>
    <isd:map encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
             xmlns:x="urn:xml-soap-soaptest" qname="x:TestEntityRemote"
             javaType="sk.humantec.hcs.ma.server.soap.TestEntityRemote"
             
java2XMLClassName="org.apache.soap.encoding.soapenc.BeanSerializer"
             
xml2JavaClassName="org.apache.soap.encoding.soapenc.BeanSerializer"/>
  </isd:mappings>
</isd:service>

Client code:
            String service = "urn:ejbsoaptest";
            Call call = new Call ();

            call.setTargetObjectURI (service);
            String encodingStyleURI = Constants.NS_URI_SOAP_ENC;
            call.setEncodingStyleURI(encodingStyleURI);

           
            call.setMethodName ("findByPrimaryKey");
            Vector params = new Vector ();
            params.addElement (new Parameter("id", Integer.class, new 
Integer(2), null));
            call.setParams(params);
            Response resp = call.invoke (/* router URL */ url, /* 
actionURI */ "" );
        // this works OK - without fail or exception
          
            String ejbKeyURI = resp.getFullTargetObjectURI();

            Call callM = new Call();
           System.out.println("ejbKeyURI:"+ejbKeyURI);
          
           callM.setFullTargetObjectURI( resp.getFullTargetObjectURI());
          
           callM.setEncodingStyleURI(encodingStyleURI);
          
           callM.setMethodName ("getValue");
           resp = callM.invoke (/* router URL */ url, /* actionURI */ "" );
// this fails with \SOAP exception - no such Method  findByPrimaryKey

thanks for any help.
