Hi,
I’m using myEclipse 4.0.0 with eclipse 3.1.0
I’m using Jboss 3.2.7 within the ide ant start it .
I want to test my EJB that i build .
I wrote a simple java client that suppose to connect to the EJB and I get
” Hello not bound “.my EJB object is is called ‘Hello’ and it is in packege ejb

Here is my full project structrue: HelloEJB/src/ejb/HelloBean .I run xdoclet

and then , deploy the Ejb. so far everything seems ok ,
i checked that the jboss really deloys the ‘ Hello.ear ‘ .

The problem occures when i run the client application which it’s code is follows:
public static void main(String[] args) {
// TODO Auto-generated method stub

HelloBean hb;
HelloHome home;
Hello h=null;
try {

Context ctx = new InitialContext();

System.out.println(“after InitialContext “);

Object objref=ctx.lookup(JNDI_NAME);

PortableRemoteObject pro=new PortableRemoteObject();

home=(HelloHome)pro.narrow(objref,HelloHome.class);
try {

h=home.create();
h.printHello();
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (CreateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

when i run this code , and get to the line ‘ Object objref=ctx.lookup(JNDI_NAME);’
i get this message : Hello not bound .

Any ideas ?
Thanks.

I am asking someone to look into this.

What is the value of JNDI_NAME? Can you post your source for the HelloBean EJB class?

Hi ,
here is my full client code :
import java.rmi.RemoteException;
import java.util.Properties;

import javax.ejb.CreateException;
import javax.naming.*;
import javax.rmi.*;

import com.sun.corba.se.impl.javax.rmi.PortableRemoteObject;
import com.sun.org.apache.xalan.internal.xsltc.runtime.Hashtable;

import ejb.Hello;
import ejb.HelloBean;
import ejb.HelloHome;

public class myHelloWorldClient {

/**
* @param args
*
*
*
*/

//public static final String COMP_NAME=”java:comp/env/ejb/HelloWorld”;
//public static final String JNDI_NAME=”ejb/HelloWorld”;

public static final String COMP_NAME=”java:comp/env”;
//public static final String COMP_NAME=”java:comp”;

// public static final String JNDI_NAME=”Hello”;

public static final String JNDI_NAME=”ejb/Hello”;

public static void main(String[] args) {
// TODO Auto-generated method stub

HelloBean hb;
HelloHome home;
Hello h=null;
try {

Context ctx = new InitialContext();

System.out.println(“after InitialContext “);

Object objref=ctx.lookup(JNDI_NAME);

PortableRemoteObject pro=new PortableRemoteObject();

home=(HelloHome)pro.narrow(objref,HelloHome.class);
try {

h=home.create();
h.printHello();
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (CreateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

}

and here is my EJB class code :
package ejb;

import java.rmi.RemoteException;

import javax.ejb.EJBException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;

/**
* XDoclet-based session bean. The class must be declared

* Below are the xdoclet-related tags needed for this EJB.
*
* @ejb.bean name=”Hello”
* display-name=”ejb/Hello”

*/
public class HelloBean implements SessionBean {

/** The session context */
private SessionContext context;

public HelloBean() {
super();
// TODO Auto-generated constructor stub
}

/**

*/
public void setSessionContext(SessionContext newContext)
throws EJBException {
context = newContext;
}

public void ejbRemove() throws EJBException, RemoteException {
// TODO Auto-generated method stub

}

public void ejbActivate() throws EJBException, RemoteException {
// TODO Auto-generated method stub

}

public void ejbPassivate() throws EJBException, RemoteException {
// TODO Auto-generated method stub

}

/**

*
* @ejb.interface-method view-type = “remote”
*

*/
public void printHello() throws EJBException {
System.out.println(“Hello !!!”);
}
/**
* An example business method
*
* @ejb.interface-method view-type = “remote”
*
*/
public void name() {
System.out.println(“EJB Statless “);
}

}

Your JNDI name that you define in the XDoclet tags in your EJB source code is called

 *  jndi-name="ejb/Hello"

. However, in your client code the JNDI_NAME constant uses “ejb/HelloWorld”. You will need to make these 2 the same. The easiest should be to just make the JNDI_NAME constant in your client “ejb/Hello”. If you change your XDoclet jndi-name tag, you will need to re-run XDoclet generation to get the new interfaces and xml files with the update jndi-name.

Hi Greg ,
Thanks for the quick answers .
I affraid that there is a misunderstanding : if you look into the client code,
you’ll see that the jndi-name is correct ( there are some other lines which refer to
jndi-name , but they are all remarked ) the correct one is with the name “ejb/Hello”

but still, when I run the client it gives me the same message “Hello not bound ”

any idea ?
Thanks.

[Greg]

Did you add the jboss subtask and specify “version” and “destDir” attributes in your XDoclet EJB configuration? If you did, make sure that the <jndi-name> tag for your Hello session bean was generated correctly in your jboss.xml file.

[eyalm]

Hi Greg ,

I didn’t add the the jboss subtask , so i didn’t have the jboss.xml file in the right
directory.After I configure the xdoclet again as in the Help manual
and running xdoclet again I see that there is a new file for jboss ( jboss.xml ) under
“C:\jboss\jboss-3.2.7\server\default\deploy ” ( as I configure it )

After redeploy the application , I moved that file to :
“C:\jboss\jboss-3.2.7\server\default\deploy\Hello.ear\HelloEJB.jar\META-INF ” .

Is it the right place ?

Now , after doing it , when I run the client , I get a new message when getting to
the line : Object objref=ctx.lookup(JNDI_NAME);
:
“javax.naming.NoInitialContextException: Need to specify class name in environment or system property …”

I checked wether the names are o.k ( as you suggested ) and everything .it all seems fine

What’s wrong ??

[Greg]

For JBoss, you have to provide a jndi.properties file in your client application.

So create a jndi.properties file that contains the following:

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=jnp://localhost:1099
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

Now this file will specify the class name for the initial context factory.

A google search of “jndi.properties jboss” brings up lots of helpful links, including this one:
http://www.huihoo.com/jboss/online_manual/3.0/ch01s15.html

[eyalm]

it seems like never ending story :
I created a new property file ( which called “jndi.properties”) put it under the classpath.
now , when I run the client I get :
“Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory ] ”

please help !

[Riyad Kalla]

eyalm,
That class should be in the jbossall-client.jar or jnp-client.jar in the JBoss directory, you can forcefully add this to your classpath by navigating to Window > Prefs > MyEclipse > App Servers > JBoss 3 > Paths, click “Add” next to Append to Classpath, and find that JAR and add it.

[eyalm]

Hi

I think I’m lost . I did as you told me : I added the 2 (!) jars which contain the NamingContextFactory.class , I even opened ( with WinRar ) these jar files to make sure that they really
contain that class , and indeed they are . I added them to the classpath of jboss ( as you instructed me ) ,and again
the same message: ” Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory ] ”

than , I added those jar to the run classpath ( via Run->Run..->classpath tab) and again
the same message.

any idea ?

[eyalm]

Continue from last message ..
I tried another way to overcome the problem :
instead of using the property file I used it in the code , i.e
“Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
“org.jnp.interfaces.NamingContextFactory”);

p.put(Context.PROVIDER_URL,”jnp;//localhost:1099″);
p.put(Context.URL_PKG_PREFIXES,”org.jboss.naming:org.jnp.interfaces”);

Context ctx = new InitialContext(p);
…
..

”
now, it doesn’t throw the ClassNotFoundException any more , BUT ,
there is a new message when I get to “lookup” line :

“Failed to initalize plugin: org.jboss.logging.Log4jLoggerPlugin@9173ef”

??

[Riyad Kalla]

eyalm,
Please email me a sample project that exhibits this problem to support@genuitec.com ATTN Riyad, I will try and solve this problem locally.

[eyalm]

I sent you a winrar file which includes all the project files.
Thanks.
