Issues when we try to lookup for EJB using T3 protocol

Question

Hi,
We have EJB's deployed in Weblogic server and we are trying to invoke them using T3 protocol.
We are facing problem as its giving the following exception
javax.naming.CommunicationException [Root exception is java.net.ConnectException: t3://170.0.10.45:7685: Bootstrap to dev2.test.zone/170.0.10.45:7685 failed. It is likely that the remote side declared peer gone on this JVM];
We tried to enable HttpTunneling in Weblogic server but it did not work.
Could anyone suggest solution for this at the earliest. Not sure whether this is a cluster issue .

Answer 1

We are trying to connect to service and EJB from our local weblogic portal
Client Server Info
Weblogic version 9.2
jdk1.5
Server Info
Weblogic version 9.2
jdk1.5
In properties file we have delcared the EJB client URL : t3://IP:7685
code
private static final String CLIENT_EJB_KEY_PREFIX = "ejbclient.";
private static final String CLIENT_EJB_JNDI_NAME_SUFFIX = ".remoteJndiName";
try {
String className = cls.getName();
String key = CLIENT_EJB_KEY_PREFIX + className + CLIENT_EJB_JNDI_NAME_SUFFIX;
LOG.debug("Looked up key of {} for className: {}", key, className);
String jndiName = cfg.getString(key);
System.out.println("Inside getHome Method : Jndi Name"+jndiName);
if (StringUtils.isEmpty(jndiName)) {
System.out.println("Inside if");
throw new ServiceNotAvailableException("Unable to locate JNDI key of %s for class %s", key, className);
Hashtable<String, String> env = new Hashtable<String, String>();
env.putAll(context.connectionEnv());
Context ctx = new InitialContext(env);
EJBHome home = (EJBHome) ctx.lookup(jndiName);
return home;
} catch (NamingException cause) {
throw new ServiceNotAvailableException(cause);
The call to EJB is failing because it is not able to communicate using T3 protocol.
