    EJB Client Error, Help.

    yufu Newbie

      I have both Session bean and Entity bean deployed to JBoss3.0+Tomcat4. When I tried to run my client program from the same PC, I got the following message:

      Got context

      javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalExcepti
      ing return; nested exception is:
      java.lang.ClassNotFoundException: org.jnp.interfaces.MarshalledValuePair
      r: RMI class loader disabled)]
      Press any key to continue . . .

      What was wrong? Do you need to add some libraries? Strangely it was working before.

          Post your client code.

            public class UserClientBean

            public UserClientBean() {


            public void startup () {

            InitialContext jndiContext = new InitialContext();
            System.out.println("Got context \n");

            Object ref = jndiContext.lookup("User");
            System.out.println("Got reference \n");

            UserHome home = (UserHome)
            PortableRemoteObject.narrow (ref,UserHome.class);

            home.create("user name", "role1", "111-112-1234", "111-112-1234",
            "111-112-1234", "Cell Number", "abc");
            home.create("useee eee", "role2", "333333333333", "888888888888",
            "999999999999", "Page Number", "abcccc");

            User user = home.findByPrimaryKey(new UserPK("user name"));

            }catch(Exception e) {

            public static void main (String args[]) {
            UserClientBean user = new UserClientBean();

            Thanks a lot.

              Do I need to set CLASSPATH for all JARs of %JBOSS_HOME%\client? Thanks.

                After I set some client jars path. I got this:

                Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Level
                at org.jnp.interfaces.NamingContext.(NamingContext.java:89)
                at org.jnp.interfaces.NamingContextFactory.getInitialContext(NamingContextFactory.java:42)

                at UserClientBean.main(UserClientBean.java:54)

                Which JAR file I need to set?
