[JNDI/Naming/Network] - Getting Exception in client code while JNDI Lookup(EJB 2.0 a
by sharma.nalin83
Hi All,
I have created a EJB proect as follows:
(1) Stateless EJB class
(2) Home Interface
(3) Remote Interface
(4) ejb-jar.xml as below:
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar id="ejb-jar_ID" version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd">
<display-name>MyEJB</display-name>
<!-- <ejb-client-jar>EJBProjectClient.jar</ejb-client-jar> -->
<enterprise-beans>
<ejb-name>MyBean</ejb-name>
src.MyBeanHome
src.MyRemoteBean
<ejb-class>src.MyBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</enterprise-beans>
</ejb-jar>
(5) jboss.xml as below:
<?xml version="1.0" encoding="UTF-8"?>
<enterprise-beans>
<ejb-name>MyBean</ejb-name>
<local-jndi-name>ejb/myEJBMapping</local-jndi-name>
</enterprise-beans>
(6) and below is my client code:
package MyClient;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.rmi.*;
import java.util.Hashtable;
import java.util.Properties;
import javax.ejb.*;
import src.*;
public class MyClient{
public static void main(String[] args){
try{
// Get an initial context
InitialContext jndiContext = new InitialContext(properties);
System.out.println("Got context");
// Get a reference to the Bean
Object ref = jndiContext.lookup("ejb/myEJBMapping");
System.out.println("Got reference");
// Get a reference from this to the Bean's Home interface
MyBeanHome home = (MyBeanHome)
PortableRemoteObject.narrow (ref, MyBeanHome.class);
// Create an Adder object from the Home interface
MyRemoteBean sp = home.create();
}catch(RemoteException rex){
rex.getLocalizedMessage();
}catch(Exception e){
e.printStackTrace(); }
}
}
After running the client code getting below exception:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645)
at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:247)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:284)
at javax.naming.InitialContext.lookup(InitialContext.java:351)
at MyClient.MyClient.main(MyClient.java:78)
Can anyone please suggest over this?
Thanks in advance.

[JNDI/Naming/Network] - Re: jndi jboss service problem connecting
by ByDcc
Well, I tried many names but the result is always the same.
Global JNDI Namespace
| ....
| +- ConnectionFactory (class: org.jboss.mq.SpyConnectionFactory)
| ....
| +- persistence.units:unitName=cartstore (class: org.hibernate.impl.SessionFactoryImpl)
| ...
| +- CartstoreFactory (class: org.jboss.ejb3.entity.InjectedEntityManagerFactory)
My code
| Object obj=ic.lookup("cartstore");
| Object obj1=ic.lookup("persistence.units:unitName=cartstore");
| Object obj2=ic.lookup("ConnectionFactory");
|
| EntityManagerFactory em = (EntityManagerFactory) ic.lookup("CartstoreFactory");
|
| CategoryEntity ce = new CategoryEntity();
| ce.setCreationDate(new Timestamp( Calendar.getInstance().getTimeInMillis() ) );
| ce.setDescription("pppppp");
| ce.setKeyName("lllllll");
| ce.setName("oooooooo");
|
| em.createEntityManager().persist(ce);
obj is null
obj1 is null
obj2 is NOT null. I have a reference to an object.
And the last line throws a NullPointerException.
