Re: [JBoss-user] Classnames in JNDI
Ole,
After restarting JBoss (2.2.1 with Jetty), the getEJBMetaData().getHomeInterfaceClass()
works the way it should again.
I am also confused, why before restarting JBoss it was acting so strange!
Now it seems to work fine.
Thanxs a lot for your help!
Best regards
Lorenzo

I dont think it should (or does), and I am a bit puzzled by
this. Just tried re-running the jbosstest CTS tests from the
latest CVS MAIN branch, and the testContainerObjects test
passes as usually:
Get the Meta-data object...OK
Probe the Meta-data object:
Home Interface : org.jboss.test.cts.interfaces.CtsBmpHome
PrimaryKey : org.jboss.test.cts.keys.AccountPK
Remote Interface: org.jboss.test.cts.interfaces.CtsBmp
Meta-data OK
Just for reference, the code that prints the above looks like:
System.out.print("Get the Meta-data object...");
EJBMetaData md = anotherHome.getEJBMetaData();
assert(md != null);
System.out.println("OK");
System.out.println("Probe the Meta-data object:");
String homeInterface = md.getHomeInterfaceClass().getName();
String primaryKey = md.getPrimaryKeyClass().getName();
String remoteInterface = md.getRemoteInterfaceClass().getName();
System.out.println(" Home Interface : " + homeInterface);
System.out.println(" PrimaryKey : " + primaryKey);
System.out.println(" Remote Interface: " + remoteInterface);
assert(homeInterface.equals("org.jboss.test.cts.interfaces.CtsBmpHome"));
assert(primaryKey.equals("org.jboss.test.cts.keys.AccountPK"));
assert(remoteInterface.equals("org.jboss.test.cts.interfaces.CtsBmp"));
System.out.println("Meta-data OK");
This test only tests the metadata for entity beans.
With which kinds of beans do you have these problems?

Re: [JBoss-user] Classnames in JNDI
Maurice,
I did set all the JNDI properties like this:
private String J2EE_BEAN_INITIAL_CONTEXT = "org.jnp.interfaces.NamingContextFactory";
private String J2EE_SERVER = "maloja:1099";
private String J2EE_SERVER_USER = "username";
private String J2EE_SERVER_PASSWORD = "password";
private Context getInitialContext()throws NamingException{
Properties p = new Properties();
p.put("java.naming.factory.initial", J2EE_BEAN_INITIAL_CONTEXT);
p.put("java.naming.provider.url", J2EE_SERVER);
if (J2EE_SERVER_USER != null) {
p.put(Context.SECURITY_PRINCIPAL, J2EE_SERVER_USER);
if (J2EE_SERVER_PASSWORD == null){
J2EE_SERVER_PASSWORD = "";
}
p.put(Context.SECURITY_CREDENTIALS, J2EE_SERVER_PASSWORD);
}
return new InitialContext(p);
}
The lookup went fine, but as soon as i called the getEJBMetaData().getEJBHome()
method on the looked up home interface , the Exception occured.
What's weird is that since i restarted JBoss, the getEJBMetaData().getHomeInterfaceClass()
and getEJBMetaData().getRemoteInterfaceClass() work fine and
return the "real" home and remote interface names.
Thanks

The $Proxy2 is a class that is dynamically generated and wraps the homeinterface methods. See java.lang.reflect.Proxy for more information. I thinkyou can use introspection to query the interfaces it implements, this shouldinclude the name of the home interface class.
There is also the getEJBMetaData().getEJBHome(), but when i call this

Re: [JBoss-user] Classnames in JNDI
Hi Rajesh,
You should be able to look up your beans in JNDI and call your desired
methods with help of java reflection.
I just tried a little example. It looks like that:
The registerEJB() method takes a JNDI context name as parameter and looks
up your beans in the given context name like "/company/applications".
public void registerEJBs(String aContextName) throws NamingException{
NamingEnumeration theNames;
Context theContext = new InitialContext();
theNames = getNames(theContext, aContextName);
while(theNames.hasMore()){
NameClassPair theName = (NameClassPair)theNames.next();
Object theObjectRef = myContext.lookup(aContextName+"/"+theName.getName());
EJBHome theHome = (EJBHome)PortableRemoteObject.narrow(theObjectRef,
EJBHome.class);
//This works so far, but i am not sure if the home interface is
always at index 0
Class theHomeInterface= theHome.getClass().getInterfaces()[0];
System.out.println("Home of "+aContextName+"/"+theName.getName()+"
is " + theHomeInterface.getName());
try{
java.lang.reflect.Method theCreateMethod;
Class[] theMethodArgs = {};
//Get the create() method
theCreateMethod = theHomeInterface.getMethod("create", theMethodArgs);
System.out.println("home interface create method " + theCreateMethod.toString());
Object[] theInvocationArgs = {};
//Invoke the create method on the home interface
Object theRemoteObject = theCreateMethod.invoke(theHome, theInvocationArgs);
//This works so far, but i am not sure if the remote interface
is always at index 0
Class theRemoteInterface = theRemoteObject.getClass().getInterfaces()[0];
//You can look up your methods like this
java.lang.reflect.Method[] theBusinessMethods;
theBusinessMethods = theRemoteInterface.getMethods();
System.out.println("The remote object is " + theRemoteInterface.getName());
}catch(NoSuchMethodException anException){
anException.printStackTrace();
}catch(java.lang.reflect.InvocationTargetException anException){
anException.printStackTrace();
}catch(IllegalAccessException anException){
anException.printStackTrace();
}
}
}
private NamingEnumeration getNames(Context aContext, String aName) throws
NamingException{
NamingEnumeration theNames;
theNames = aContext.list(aName);
return theNames;
}
I hope that this helped so far
Cheers

Re: [JBoss-user] Classnames in JNDI
Alexander,
I know that somebody has to implement an interface.. That's not the point.
I was simply trying the find the name of the home interface.
It would be nice if JBoss would publish the name of the home interface in
JNDI.
Shouldn't the getEJBMetaData().getHomeInterfaceClass() return the home interface,
or does it
return the class that implements the home interface?
Thanks
Lorenzo

Lorenzo,
1. Actually the *real* name is the "$ProxyN".
JBoss uses dynamic proxy to construct a
sort of stub for your EJB client.
The returned "$Proxy" class implements
your HomeInterface.
2. You HomeInterface is the *interface*.
So anyway, something should implement it.
What did you expect?
3. You may get the list of interfaces and/or
your real HomeInterface by using reflection.

Re: [JBoss-user] Classnames in JNDI
Hi Burkhard,
The problem is that i don't know the bean's name. The list() method returns
an enumeration of JNDI names found in the given context. If you have deployed
beans in the context, you
can get at the name and classname through the NameClassPair class.
I have also tried your approach : home.getEJBMetaData().getHomeInterfaceClass(),
but i still get only classnames like "$Proxy0".
Do you get the real classnames?
Thanks
