HibernateUserImpl cannot be cast to org.jboss.portal.identit

[mars76]

Hi All,

I am trying to get the User Object from the User Module and i am getting the following exception:

java.lang.ClassCastException: org.jboss.portal.identity.db.HibernateUserImpl cannot be cast to org.jboss.portal.identity.User
 at $Proxy289.findUserByUserName(Unknown Source)
 at test.portlet.ChangePasswordPortlet.getUser(ChangePasswordPortlet.java)
 at test.portlet.ChangePasswordPortlet.isValidCurrentPassword(ChangePasswordPortlet.java)
 at test.portlet.ChangePasswordPortlet.checkInputValdiity(ChangePasswordPortlet.java)
 at test.portlet.ChangePasswordPortlet.doView(ChangePasswordPortlet.java:)
 at javax.portlet.GenericPortlet.doDispatch(GenericPortlet.java:328)
 at javax.portlet.GenericPortlet.render(GenericPortlet.java:233)

The code i have is:

 private UserModule getUserModule()
 {
 UserModule userModule = (UserModule) getPortletContext().getAttribute("UserModule");
 if(userModule==null)
 {
 try
 {
 userModule = (UserModule)new InitialContext().lookup("java:portal/UserModule");
 }
 catch(NamingException ne)
 {
 ne.printStackTrace();
 }
 }
 return userModule;
 }


 private User getUser(RenderRequest request)
 {
 User user = null;
 try
 {
 UserModule userModule = getUserModule();
 String userName = getUserName(request);
 if(userModule!=null)
 {
 user =userModule.findUserByUserName(userName);
 }
 }
 catch (IllegalArgumentException e)
 {
 e.printStackTrace();
 }
 catch (NoSuchUserException e)
 {
 e.printStackTrace();
 }
 catch (IdentityException e)
 {
 e.printStackTrace();
 }
 return user;
 }

 private String getUserName(RenderRequest request) {
 String userName = request.getRemoteUser();
 if(userName==null && request.getUserPrincipal()!=null)
 {
 userName = request.getUserPrincipal().getName();
 }
 return userName;
 }

And in jboss-portlet.xml i have specified the required services..

<portlet-app>
 <portlet>
 <portlet-name>ChangePasswordPortlet</portlet-name>
 <transaction>
 <trans-attribute>Required</trans-attribute>
 </transaction>
 </portlet>
 <service>
 <service-name>UserModule</service-name>
 <service-class>org.jboss.portal.identity.UserModule</service-class>
 <service-ref>:service=Module,type=User</service-ref>
 </service>
 <service>
 <service-name>UserProfileModule</service-name>
 <service-class>org.jboss.portal.identity.UserProfileModule</service-class>
 <service-ref>:service=Module,type=UserProfile</service-ref>
 </service>

Pls let me know why i am getting this strange exception as HibenrateUserImpl implemets the Interface User !!!!!
