For each call, a new TCP connection is opened, with a different local port. So there is also a performance problem. Here is a simple code to reproduce : -- EJB3 remote Interface -- package ejb; import javax.ejb.Remote; @Remote public interface Foo { public void bar(); } -- EJB3 Implementation -- package ejb; import javax.ejb.Stateless; @Stateless public class FooBean implements Foo { public void bar() { } } -- client -- package client; import java.util.Properties; import javax.naming.Context; import javax.naming.InitialContext; import ejb.Foo; public class Test { public static void main(String[] args) { try { Properties env = new Properties(); env.put(Context.PROVIDER_URL, "jnp://localhost:1099"); env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); env.put("jnp.disableDiscovery", "true"); Context context = new InitialContext(env); Foo foo = (Foo)context.lookup("FooBean/remote"); while(true) { foo.bar(); } } catch (Exception e) { e.printStackTrace(); } } } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
