    UserImpl not mapped

    pedro costa Apprentice

      I'm trying to access jbp_users table from jboss Portal database, but i get the following error:

      org.hibernate.hql.ast.QuerySyntaxException: UserImpl is not mapped. [FROM UserImpl user WHERE 1 = 1 and userName = :userName]
      


      I putted a query string in my program to get a result.

      I've noticed that the mapping file that corresponds to jbp_users tables is

      D:\jboss\jboss-portal-2.2.0-src\core\src\resources\portal-core-sar\conf\hibernate\user\domain.hbm.xml

      and not UserImpl.hbm.xml.

      I putted portal-core-lib.jar in the classpath of my program.

      But still get the error.

      Any help?

      Thanks,
      Pedro

            why don't use the UserModule ?

              Thanks for the quick advice. Now it works.

                No it doesn't work. :(

                1 - Can you put an example that works?

                2 - Should i start a service before doing findUserByUserName?

                UserModule mod = new UserModuleImpl();
                User user = mod.findUserByUserName(username);
                


                I'm asking this question because this snippet gives me the following error:

                java.lang.NullPointerException
                 at org.jboss.portal.core.impl.user.UserModuleImpl.getCurrentSession(UserModuleImpl.java:372)

                And i saw that UserImpl as a protected method startservice.

                The mssql-ds.xml are well configurated.

                Thanks,

                  To solve this problem do this:

                  UserModule mod = (UserModule) new InitialContext().lookup("java:portal/UserModule");

                    i think you can inject the service in the portlet :

                    in jboss-portlet.xml:

                    <service>
                     <service-name>UserModule</service-name>
                     <service-class>org.jboss.portal.core.modules.UserModule</service-class>
                     <service-ref>:service=Module,type=User</service-ref>
                     </service>


                    and get the usermodule in the portlet :

                    userModule = (UserModule)getPortletContext().getAttribute("UserModule");

                      yes this saves a JNDI lookup :-)

                        Hi,
                        You may know this already but as i have just hit it myself i thought i'd mention this anyway. make sure that you are using stateful session beans with the EntityManager for multiple calls to beans. the annotation should be something like this:

                        @PersistenceContext(unitName="myEjb", type=PersistenceContextType.EXTENDED).
                        The
                        QuerySyntaxException: myEjb not mapped
                        occurs because the injected persistence manager is closed once a stateless been is returned to the pool.

                        regards abuayyub

                          instead of using the name of table in query string you
                          must use the name of class being mapped

                            I need to connect to userModule from my plain java class. How to go about it.

                            I have tried the followig
                            UserModule mod = (UserModule) new InitialContext().lookup("java:/portal/UserModule");

                            It gives the following error
