    Resolving problems with inheritance

    Klaus Erber Newbie

      Hello,

      at the moment, we are evaluating the new JBossWS webservice stack for a new project to use it instead of a self deployed AXIS context.

      First of all: Thank you for the great work!

      For the test, we have a CVS/SVN version of JBoss-4.0.4.GA/JBossWS from 2006-04-25

      We run into problems, when we try to use inheritance in our parameter und result types. For example:

      we have as JSR181 conforming class:

      package de.spiegel.red.service.ws.auth;
      @WebService( name="AuthentifizierungJws",
       targetNamespace="http://auth.ws.service.red.spiegel.de",
       serviceName="AuthentifizierungJws")
      @SOAPBinding(
       style=SOAPBinding.Style.RPC,
       use = SOAPBinding.Use.LITERAL)
      @Stateless
      public class AuthentifizierungJwsServiceBean extends CoreJwsServiceBean
       implements AuthentifizierungJws
      {
      ...
      
       @WebMethod
       public LoginErgebnis login(LoginParam loginParam)
       {
       ...
       }
      }
      

      The class LoginParam:

      package de.spiegel.red.service.ws.auth;
      public class LoginParam extends CoreParamWSO implements java.io.Serializable {
       ...
      }
      


      and the base class:

      package de.spiegel.red.service.ws;
      public class CoreParamWSO implements java.io.Serializable {
       private JwsParam jwsParam;
       ...
      
       public JwsParam getJwsParam() {
       return jwsParam;
       }
      
       public void setJwsParam(JwsParam jwsParam) {
       this.jwsParam = jwsParam;
       }
      }
      


      That results in the following WSDL, using the wstools:

      During deployment we get these errors:

      ok, I can understand it. There is no type 'tns:CoreParamWSO' defined in JBossWS_auth.ws.service.red.spiegel.de16628.xsd, that is used as the extension base:

      ...
      <extension base='tns:CoreResultWSO'>
      ...
      


      There is one in JBossWS_ws.service.red.spiegel.de_jaws16629.xsd. But how can we avoid the problem? It seems that the non-jaws file have to include the jaws-file, or so. I have also try to put all classes in one java package, but the result is the same.

      best regards
      Klaus
