java.lang.ClassCastException: org.jnp.interfaces.NamingConte

Hi,

I am sorry if this has been posted before. I did a search and nothing came back.

I developed a very simple EJB3.0 Stateless Session Bean. I created a client that calls this session bean as follows:

public static void main(String [] args) {
 try {
 final Context context = getInitialContext();
 ReadCrimeReport readCrimeReport = (ReadCrimeReport)context.lookup("ReadCrimeReport");
 } catch (Exception ex) {
 ex.printStackTrace();
 }

 private static Context getInitialContext() throws NamingException {
 Hashtable env = new Hashtable();
 env.put( Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory" );
 env.put(Context.PROVIDER_URL, "localhost");
 env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" );
 return new InitialContext( env );
 }

I deployed the EJB and see the following

09:13:04,288 WARN [Ejb3DescriptorHandler] Descriptor based bean has no ejb-clas
s defined: ReadCrimeReportBean
09:13:04,328 INFO [JmxKernelAbstraction] creating wrapper delegate for: org.jbo

e: ReadCrimeReport
09:13:04,678 INFO [EJB3Deployer] Deployed: file:/D:/jboss-4.2.1.GA/server/defau
lt/deploy/ejb1.jar

Now when I run the client, I am getting

java.lang.ClassCastException: org.jnp.interfaces.NamingContext
at client.ReadCrimeReportClient.main(ReadCrimeReportClient.java:15)

It is complaining on

ReadCrimeReport readCrimeReport = (ReadCrimeReport)context.lookup("ReadCrimeReport");

Thanks for your help.

Hi,

I was able to fix the issue. It turns out that I needed to access the SLSB as follows in the client:

ReadCrimeReport readCrimeReport = (ReadCrimeReport)context.lookup("ReadCrimeReport/remote");


Please note ".../remote" in the lookup.

Thanks,

Mustafa
