Hi all, I have a similar issue too. I am experimenting with EJB3 deployed on JBoss 4.0.5 (the jar installer version). The deployed jar file (called SimpleSession.ejb3) has 2 classes:- SimpleSession.class (remote interface) and SimpleSessionBean.class (the bean). This deploys with no issues but from a JSP client calling the EJB with the following code String theString = null; InitialContext ctx = new InitialContext(); simpleSession=(SimpleSession)ctx.lookup(SimpleSession.class.getName()); theString = simpleSession.sayHello(); I get the following error message: 10:52:55,968 ERROR [STDERR] javax.naming.NameNotFoundException: beans.SimpleSession not bound 10:52:55,968 ERROR [STDERR] at org.jnp.server.NamingServer.getBinding(NamingServer.java:529) 10:52:55,968 ERROR [STDERR] at org.jnp.server.NamingServer.getBinding(NamingServer.java:537) 10:52:55,968 ERROR [STDERR] at org.jnp.server.NamingServer.getObject(NamingServer.java:543) 10:52:55,968 ERROR [STDERR] at org.jnp.server.NamingServer.lookup(NamingServer.java:296) 10:52:55,968 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 10:52:55,968 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) 10:52:55,968 ERROR [STDERR] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) Etc.... I also noted that the bean was registered with JBoss from the service=JNDIView parameter on the jmx-comsole. Does anyone have an idea of what could be wrong here. Any Help will be much apreciated.
