Unable call ejb remote in weblogic 10.3

Question

hi all,
I am trying to call a remote service deployed in weblogic 10.3 here are my classes
@Stateless (mappedName = "ejb/engine")
@TransactionManagement(value=TransactionManagementType.CONTAINER)
public class JsacEngineEJB implements JsacEngineEJBRemote {
     @Override
     public User getUserByID(String userId) {
          User ret = null;
          try {
          return ret;
@Remote
public interface JsacEngineEJBRemote {
public User getUserByID(String userId);
private static Object jndiLookup(String jndiName) throws NamingException {
          final Object obj;
          try {
          obj = ctx.lookup(jndiName);     
          } catch (NamingException e) {
               log.logFatal("Can not found JNDI name: " + jndiName);
               throw e;
          return obj;
String jndi = "ejb/engine#"
final String jndiName =jndi+beanClass.getCanonicalName();
final T bean = (T)jndiLookup(jndiName);
the exception
java.lang.reflect.UndeclaredThrowableException
     at $Proxy61.getUserByID(Unknown Source)
java.lang.NoSuchMethodException:
     at java.lang.Class.getMethod(Class.java:1605)
     at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.getTargetMethod(RemoteBusinessIntfProxy.java:162)
     at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.invoke(RemoteBusinessIntfProxy.java:53)
     Truncated. see log file for complete stacktrace
any idea???
Best regards

Hi,
It seems that the Followinf line of code is causing the issue:
String jndi = "ejb/engine#"
<font color=red>final String jndiName =jndi+beanClass.getCanonicalName();</font><BR>
final T bean = (T)jndiLookup(jndiName);
Is it possible for you to Not to use the ".getCanonicalName()" method. Rather u can use a Simple Custom JNDI Name for your EJBs. Like: http://weblogic-wonders.com/weblogic/2009/08/21/custom-jndi-ejb3/
Sometimes we get the following errors if we dont generate the EJB Client artifacts to be used at client end. Please try generating EJB Client JAR...as well: http://weblogic-wonders.com/weblogic/2010/04/02/generating-ejb3-clientjar/
java.lang.NoSuchMethodException:
at java.lang.Class.getMethod(Class.java:1605)
at weblogic.ejb.container.internal.RemoteBusinessIntfProxy.getTargetMethod(RemoteBusinessIntfProxy.java:162)
