JNDI look up of remote interface is not working
Hi All,
I have googled this problem a lot but coudnt able to find answer of this. Any assistance would be appreciated because i m just stuck up here,,,
I m using jboss4.0.4CR2 on linux
When, I m calling remote interface of a stateless session bean then its giving me the following error.
javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException: org.jboss.ejb3.JBossProxy (no security manager: RMI class loader disabled)] at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:728) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:587) at javax.naming.InitialContext.lookup(InitialContext.java:351) at mailTest.main(mailTest.java:25) Caused by: java.lang.ClassNotFoundException: org.jboss.ejb3.JBossProxy (no security manager: RMI class loader disabled) at sun.rmi.server.LoaderHandler.loadProxyClass(LoaderHandler.java:531) at java.rmi.server.RMIClassLoader$2.loadProxyClass(RMIClassLoader.java:628) at java.rmi.server.RMIClassLoader.loadProxyClass(RMIClassLoader.java:294) at sun.rmi.server.MarshalInputStream.resolveProxyClass(MarshalInputStream.java:238) at java.io.ObjectInputStream.readProxyDesc(ObjectInputStream.java:1494) at java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1457) at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1693) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1299) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:339) at java.rmi.MarshalledObject.get(MarshalledObject.java:135) at org.jnp.interfaces.MarshalledValuePair.get(MarshalledValuePair.java:72) at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:652) ... 3 more
My Client code looks like this
try {
Hashtable<String,String> environment = new Hashtable<String,String>();
environment.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
environment.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
environment.put(Context.PROVIDER_URL, "jnp://10.0.0.10:1099"); // remote machine IP
InitialContext context = new InitialContext(environment);
Object obj = context.lookup("EmailSessionBean/remote");
//EmailFacade home = (EmailFacade)PortableRemoteObject.narrow(obj, EmailFacade.class);
System.out.println("lookup done successfully");
}
catch (Exception e) {
System.out.println("exception caught");
e.printStackTrace();
}When i invoke list on jndi view its giving me the following

I am calling my server bean interface with adding this jar in client classpath
/usr/local/jboss-4.0.4.CR2/client/jboss-aspect-jdk50-client.jar
and i do have jboss-ejb3.jar in $jboss_home/server/default/deploy/ejb3.deployer
Please suggest me where the problem is...
Thanks in anticipation
