Executing Remote-Method with Swing Client fails
empinator Sep 6, 2007 3:03 PMHello,
I'm using JBoss 4.0.5GA as ApplicationServer
having a Swing Client receiving the Business Logic through EJB.
Both running with Java 1.6.
They client-application is downloaded via WebStart containing all its neccassary libraries in the codebase folder
<jnlp spec="1.5+" codebase="http://localhost:8080/tima-client/application" href="launch.jnlp"> <security> <all-permissions/> </security> <resources> <j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se" java-vm-args="-Xmx250M" /> <jar href="binding-1.3.1.jar"/> <jar href="jboss-aop-jdk50.jar"/> ... </jnlp>
Receiving the Remote-Bean is successful, but when I'm trying to execute a specific method of this bean, my application stalls without throwing an Exception.
However this phenomen doesn't occur while running my client with eclipse.
Here's my code:
public class RemoteBeanUtil { /** Login */ private final static String sLoginUc = "LoginUcImpl"; private static InitialContext getInitialContext() throws NamingException { Properties lP = new Properties(); lP.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); lP.put(Context.URL_PKG_PREFIXES, " org.jboss.naming:org.jnp.interfaces"); lP.put(Context.PROVIDER_URL, "jnp://antonius:1099"); return new InitialContext(lP); } private static Object getBean(String pBeanName, Class<? extends Object> pName) throws NamingException { Object lRef = null; InitialContext lInitialContext = getInitialContext(); lRef = lInitialContext.lookup(pBeanName + "/remote"); return PortableRemoteObject.narrow(lRef, pName); } public static LoginUc getLoginUc() throws Exception { return (LoginUc) getBean(sLoginUc, LoginUc.class); } }
@Stateless public class LoginUcImpl extends UcImplBase implements LoginUc { public Benutzer authenticate(String pUser, String pPass) { // Businesslogic } }
// Client LoginUc lLuc = RemoteBeanUtil.getLoginUc(); if(lLuc == null) { System.out.println("not here!"); } Benutzer lBen = lLuc.authenticate(pUser, lPw); System.out.println("here!"); // <-- unreached code!!
Any help, hints or suggestions are welcome!!
Thanks a lot
