[jboss-user] [EJB/JBoss] - Executing Remote-Method with Swing Client fails
Hello,
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
empi
