Below, you find the Java code related to the call of EJB in remoting way.
try {
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY,
"org.openejb.client.RemoteInitialContextFactory");
properties.put(Context.PROVIDER_URL, "ejbd://localhost:" + "4202");
InitialContext context = new InitialContext(properties);
NamingEnumeration<Binding> listBindings = context.listBindings("");
Map<String, Object> map = new HashMap<String, Object>();
while (listBindings.hasMoreElements()) {
Binding pair = listBindings.nextElement();
System.out.println(pair.getName());
// map.put(pair.getName(), pair.getObject());
}
Object ref = context.lookup("EchoImplRemote");
} catch (Exception e) {
e.printStackTrace();
}
}
I can't to lookup object because a nullpointer exception is thrown. But i
can enumerate EJB naming.
.
EchoImplRemote
EJBBonjourRemote
java.lang.NullPointerException
at
org.apache.openejb.client.JNDIContext.createBusinessObject(JNDIContext.java:203)
at org.apache.openejb.client.JNDIContext.lookup(JNDIContext.java:247)
at javax.naming.InitialContext.lookup(InitialContext.java:392)
at test.openejb.remote.StandaloneClient.main(StandaloneClient.java:84)
>From the OpenEJB server side log, i notice that there is one method have
been invoked
INFO - invoking method create on EchoImpl
DEBUG - finished invoking method create. Return
value:proxy=fr.ensma.lisi.testejbbundle.Echo;deployment=EchoImpl;pk=null
DEBUG - JNDI REQUEST: JNDI_LOOKUP:null:EchoImplRemote -- RESPONSE:

DEBUG - JNDI REQUEST: JNDI_LOOKUP:null:EchoImplRemote -- RESPONSE:

As you can see, pk value is null
Thanks a lot
