EJB publisher -- Normal Java Client

I'm having a problem with publishing from an EJB.
I am trying to publish a topic from Session Bean in Weblogic server. And a normal client is subscriber for the topic. When I publish a message from the EJB, client is not getting the messages. While I am monitoring the Topic, it is receving the messages from bean, that is, Messages Received is increasing each time the EJB publishes. But the client is not receiving any message. Consumers Total is displayed as 1.
Could anybody tell me what might be the problem.
Thanks in advance.
Supriya

I got the solution. Thank you if anybody tried to find the solution.

Looking up EJBs from a java client

While trying to migrate my application from standalone-oc4j
to Oracle Application Server 10g, I ran into the following problem.
My application has a stateless session bean. When trying to lookup the bean (from a java client), I get the following exception:
javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException
Invalid username/password for UnifyoccEAR (ias_admin)
My code used the username/password I used to log into web-based console (which I used to deploy the application). The lookup code follows:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
OracleJASLayer.INITIAL_CONTEXT_FACTORY);
env.put(Context.PROVIDER_URL, "ormi://localhost:3201/UnifyoccEAR");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, username);
env.put(Context.SECURITY_CREDENTIALS, password);
Context ctx = new InitialContext(env);
Object obj = ctx.lookup("unify/nxj/controlCenters/occ/ControlCenterEJB");
On a whim, I tried the old SCOTT/TIGER username/password and got the following
exception:
javax.naming.NoPermissionException: Not allowed to look up unify/nxj/controlCenters/occ/ControlCenterEJB,
check the namespace-access tag setting in orion-application.xml for details
So evidently, SCOTT/TIGER is in the security database used by the app (but isn't
authorized) while the ias_admin user is not in the security database.
I have the following questions:
1. In the default configuration, is there a username/password I can use to
lookup EJB homes in the jndi namespace of an OC4J instance? If so, what
is it?
2. Where is the security database? I tried looking in the web-based console
to find how to configure security and could not figure it out. I did find
the Security page for the application, but when I tried to add a user,
it had no effect. Furthermore, this page did not show a user entry for
SCOTT; hence, it doesn't seem that OC4J is actually using the information
on this page. This is strange because the path to this page is:
Farm > Application Server: ias_admin.lab10.sac.unify.com > OC4J: home > Application: UnifyoccEAR > Security
I then went to the Security page for the default application and found
that it did have a SCOTT user. So I added a new user and tried to run
my java client. This resulted in the javax.naming.AuthenticationException
described above (I was expected the NoPermissionException encounted when
using SCOTT/TIGER). Next, I used the Security page for the default application
to change the password for SCOTT and reran my java client using SCOTT/TIGER.
This time I was expecting an AuthenticationException exception, but got the
NoPermission exception. Therefore, it seems that OC4J isn't using this
security data either.
Hunting in the console (again) for the security database, I stumble accross
the Infrasturcture page and see an Identity Management section and see that
it is configure to use an Oracle Internet Directory server. Using
<ORACLE_HOME>/bin/oidadmin, I connect to the directory server and look
for the SCOTT user. I don't find it, so I believe that this can't be the
security database either.
3. Finally, how do I configure the OC4J instance such that it will allow
anonymous users to lookup my EJB from a java client?
Please help a confused and frustrated user.

Looking at your example, it looks like you are using a J2EE client container or some properties file to specify the JNDI environment used to create the initial context (for you use the no-arg constructor to InitialContext). Since our application needs to the ability to dynamically connect to ejb's running on different Java application servers (e.g., WebLogic, WebSphere, JBoss), such an approach will not work. Instead we must do it the old-fashioned way and pass the jdni connection info to the InitialContext constructor.
In any event, our problem isn't how to write the connection code, it is how to test it. Specifically, we can't figure out a valid username/password that will allow us to look up the home. Nor can we figure out how to configure security for the oc4j instance.

How do I call an ejb from a java client?

I put ejb classes in a jar file along with java client code and deployed it on my OC4J server. Now I am trying to run the ejb by calling the client code on my OC4J server from the command line but I am not having success. Am I doing this the right way? Should I also deploy my client code? Should the client code also be in a directory on my OC4J server?

Hi. Here is a part of the code for a java client. In this particular case it is also an EJB but it is a Message Driven Bean.

Calling EJB from from a client app

Hi all,
I am trying to call an EJB component from portal. The example EJB I have taken is from SDN Bonus Calculator example - Application Server/Web Dynpro/Samples and Tutorials/Using EJBs (20)
I deployed the EAR file - no issue
I wrote the following code in a client app and trying to connect to the EJB remotely.
          try {
               java.util.Properties properties = new Properties();
               properties.put(Context.INITIAL_CONTEXT_FACTORY, "com.sap.engine.services.jndi.InitialContextFactoryImpl");
               properties.put(Context.PROVIDER_URL, "ux0800:55304");
               InitialContext ctx = new InitialContext(properties);
               //InitialContext ctx = new InitialContext();
               // get ejb home
               home =
                    (BonusCalculatorLocalHome) ctx.lookup(
                         "localejbs/MySessionBean");
               theCalculator = home.create();
          } catch (Exception namingException) {
               namingException.printStackTrace();
I get the following error
javax.naming.NoInitialContextException: Cannot instantiate class: com.sap.engine.services.jndi.InitialContextFactoryImpl [Root exception is java.lang.ClassNotFoundException: com.sap.engine.services.jndi.InitialContextFactoryImpl]

Hi Sabbir,
Following code works for me in calling EJB from normal java application. Did you added the jar files to your application?. see the required jar files in end of code.
Create simple java applcation do the following steps:
Give JNDI name to the EJB(HelloJNDI)->Add the HelloEJB to HelloEAR ->deploy
Proxy Program to call ejb:
import javax.naming.Context;
import javax.naming.InitialContext;
import com.sample.Hello;
import com.sample.HelloHome;
public class HelloTest {
     public static void main(String[] args) {
                   Hello remote = null;
                  try {
                    Context ctx = new InitialContext();
                    HelloHome home = (HelloHome) ctx.lookup("HelloJNDI");
                    remote = home.create();
                    String result = remote.hello();
                    System.out.print("Result:" + result);
                     } catch (Exception e) {
                            System.out.println("Exception:" + e.getLocalizedMessage());
1. Go To Run > Java Application ->New->select your project and select your main class(java program from which your going to call EJB)
2. Click next tab ->(x)=Arguments
paste the following code in VM Arguments
-Djava.naming.factory.initial=com.sap.engine.services.jndi.InitialContextFactoryImpl -Djava.naming.provider.url=localhost:50104
replace the server IP address with your server IP address where your ejbs are running.
Under Class path settings for the program put the following jar files.
You can search for them from net weaver soruce folders
or copy from D:\usr\sap\J2E\JC01\j2ee\j2eeclient
ejb20.jar
logging.jar
exception.jar
sapj2eeclient.jar
Add Corresponding ejb.jar
and RUN >>>
this makes testing of your client programs easier, you can find the error trace on which line and saves lot of time.

Is it a remote lookup? Then maybe this will help:

Creating multiple stateful session beans from a java client. (EJB 3.0)

I'm having difficulties with the following:
To access the ShoppingCartBean, I have to put the following annotation in my standalone java client:
@EJB
private static ShoppingCartRemote shoppingCartBean;
The static must be there, thus only one ShoppingCartBean will exist within my java client. But as the ShoppingCartBean is a stateful session bean, I want to be able to get different beans of the same type.
What is the correct way to do this in EJB 3.0?

Great question. Because Home interfaces have been removed for the EJB 3.0 simplified
API, stateful session bean creation happens as a side-effect of injection. However, the
same is true of EJB 3.0 business interface lookups. The easiest way to create additional
stateful session beans is to lookup the same dependency that was declared via your
@EJB annotation.
E.g.,
// Assuming the declaring class is pkg1.ShoppingCartClient.java
InitialContext ic = new InitialContext();
ShoppingCartRemote scr1 = (ShoppingCartRemote)
ic.lookup("java:comp/env/pkg1.ShoppingCartClient/shoppingCartBean");
Note that the name relative to java:comp/env is the default associated with your
@EJB annotation since the name() attribute wasn't used. Alternatively, you
could have used :
@EJB(name="scb") private static ShoppingCartRemote shoppingCartBean;
InitialContext ic = new InitialContext();
ShoppingCartRemote scr1 = (ShoppingCartRemote) ic.lookup("java:comp/env/scb");
Yet another alternative is to declare the @EJB at the class-level. This just defines
the dependency without any injection, which is fine if you want to create a bunch of
them via lookup anyway.
@EJB(name="scb", beanInterface=ShoppingCartRemote.class)
public class .... {

Finding an EJB object. Web clients vs. Java clients

From what I've read this is the process for a web client to find an EJB object: the client uses JDNI to find a reference to the EJBHome interface and then it uses the create method from this interface which makes the container to begin to work, creating an instance of the implementation class and an instance of the EJBObject interface, and returning a reference to the EJBObject, which will be used by the client to call the methods.
Are there any differences if the client is a java application and not a web client?

The Java Client talk to the server with random ports
not 80. Gives me a headache. _*why?
There's no need to get headaches about it, in fact no need to worry about it at all.
Just have the JNDI services available so you can do the lookup (which might require opening a port (or more than one) on the firewall, but that's it.
And that's no different between a standalone client and a web application client. Both need to do that JNDI lookup.

Problem running Java client of EJB deployed on WebSphere

Hi,
I am using websphere studio 5.1.2 with fix pack 3. I have a sample Stateless Session Bean (EJB) deployed and running on websphere.
I wrote a small Java client program as below.
import java.util.Hashtable;
import HelloJavaHome;
import HelloJava;
import javax.naming.InitialContext;
import javax.naming.Context;
import javax.ejb.EJBHome;
import javax.ejb.EJBObject;
public class RemoteConn {
public static void main(String[] ar) throws Exception{
String greeting = "";
try{
Hashtable env = new Hashtable();
//env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
//env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ejs.ns.jndi.CNInitialContextFactory");
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.ws.naming.util.WsnInitCtxFactory");
//env.put(Context.PROVIDER_URL, "corbaloc:iiop:myhost.mycompany.com:2809/NameServiceCellPersistentRoot");
env.put(Context.PROVIDER_URL, "iiop://localhost:2809");
System.out.println("Before creating context ");
InitialContext initContext = new InitialContext(env);
System.out.println("Before looking up HelloJavaHome.");
//Object obj = initContext.lookup("java:comp/env/ejb/HelloJavaHome");
Object obj = initContext.lookup("ejb/HelloJavaHome");
System.out.println("After lookup javahome.");
HelloJavaHome home = (HelloJavaHome) javax.rmi.PortableRemoteObject.narrow(obj, HelloJavaHome.class);
HelloJava remote = home.create();
greeting = remote.getGreeting("John");
catch(Exception e){
e.printStackTrace();
System.out.println("Greeting::"+ greeting);
I did not have any problem if I write and run this client from Websphere studio environment..
However its giving lot of compilation and runtime errors when I tried to run from command line.
I could eliminated compilation errors by setting the below jar files in the classpath.
testclient.jar; (client jar of my EJB)
j2ee.jar;
naming.jar;ras.jar;
wsexception.jar;
bootstrap.jar;
namingclient.jar;
websphere.jar;server.jar;
ejbcontainer.jar;
ecutils.jar;
Now it is throwing runtime error after the statement, "Before looking up HelloJavaHome.", has printed. Here is the stack trace of exception ..
Exception in thread "main" java.lang.NoClassDefFoundError: com.ibm.CORBA.iiop.GlobalORBFactory

Also include idl.jar and ffdc.jar on the classpath

Java client ejb access

Hi
Am I correct in thinking that if I require a browser based Java
client to access an EJB that I have to perform the following ....
SETUP for the browsers
1) You need to remove the iiop10.jar file from the
...Netscape/Communicator/Program/Java/Classes directory. Renaming
this
file is not enough - you must remove it.
2) You need to copy $ORACLE_HOME/lib/aurora_client.jar
$ORACLE_HOME/lib/vbjorb.jar and $ORACLE_HOME/lib/vbjapp.jar into
the
...Netscape/Communicator/Program/Java/Classes directory.
aurora_client.jar is 2.3MB! This effectively means ejb's are
totally useless in the real world if you want to access them from
a browser over the internet.
Somebody please tell me there's an alternative or even better
it's not true.
Thanks

Check the JNDI name specified in the xml file.
Hope this will help

Creating a simple java client for a session EJB local interface

Hi all
Is it possible to create a simple java client for a session ejb local interface with JDeveloper.
The problem is that it creates a test client for a remote interface only...
i.e.
MySessionEJB sessionEJB = context.lookup("MySessionEJB")
and once i try to adjust it manually for the local interface...
MySessionEJBLocal sessionEJB = (MySessionEJBLocal) context.lookup("MySessionEJBLocal") (MySessionEJBLocal - is the name of my local interface)
it generates the exception:
javax.naming.NotFoundException: SessionEJBLocal not found
at...........................(RMIClientContext.java:52)
There is still no problem with accessing the local interface object from the jsf project where i've added <ejb-local-ref> tag into the web.xml file.
but i need the possibility of testing the simple java client for the local interface to test business methods wich should return objects without indirect properties
Thanks in advance.
Alex.

Pedja thanks for reply.
I still dont understand what is wrong with my example.
The first peace of the code i wrote (getting the reference to the remote interface object) works pretty well, and even more it is produced automatically by JDeveloper, so why we cant get a reference to the local interface object the same way?
Certanly we should use the local interface for getting access to the resource functioning under the same local jvm and i think it doesnt metter wich app server we really use wls or oas or others
Thanks. Alex.

Access a normal java class from EJB

how can i access normal java class from an EJB.
I do not want to write the business logic inside the EJB. How can I achieve this.

There's no special API for doing this. Just use normal java. E.g.
@Stateless
public class FooBean implements Foo {
public void foo() {
// access non-EJB utility class Bar
Bar b = new Bar();
b.bar();
}

RMI - EJB Standalone Java client

Hello,
We have a standalone Java client attempting to invoke a EJBs running on OC4J. We get a user not allowed to access namespace...check orion-application.xml file... Any ideas what could be the problem.
Regards.

Hi,
In access namespace tag of your orion-application.xml, you should specify the same user as the one used by your java client.
Hope that helps

EJB Java Client to Corba C++ object

Does BEA have any examples of calling from an EJB java client to a CORBA C++ object
(please no Tuxedo examples, thank you)?
I've tried the c++ -> EJB examples, however now I need the other way around.
thanks,
Sean

Thank you.

In terms of scalabilty, will static method in normal java class better than

You only have one copy of the static method in memory, but you have a few copy of the stateless session bean, plus the overhead of those session bean.So isn't static method of normal java class more scalable than stateless session bean.

Then you have to take care of transaction management, connection pooling, etc other ejb services all by your self.
In fact stateless session beans acts more like a static class. They do not get destroyed when remove() method is called on client stub. Similarly they are not always gets created whenever someone calls create() method on home interface!! (Again it's specific to appserver implementation)
Thx.
