EJB reference not bound

I'm running JBoss 3.0.1 with Tomcat 4.0.4 bundle. I have successfully deployed a EJB to Jboss and created 2 clients (java & JSP client).
For some reasons, I'm able to run the java client but when I try the JSP client (served by Tomcat) I get this error message
javax.servlet.ServletException: Name greetings is not bound in this Context
Below is the code for the 2 clients & web.xml

Why is it not bound?

Please Ignore my other Message(My META-INF was not in Root and now I am able to get my beans bound).
I am using Jboss 3.0
I am able to access service of my HelloWorld Session Bean through a jsp.
But not able to do so using a java client.
my directory structure is :
com\ideas\users\<Bean classes(Remote Interface,home interface,Bean)>
com\ideas\users\<Bean client(a java client)>
My java client program is :
import javax.rmi.*;
import javax.naming.*;
import java.util.*;
import com.ideas.users.*;
public class HelloWorld {
public static void main( String args[]) {
try{
Properties p = new Properties();
          p.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
          p.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
          p.put("java.naming.provider.url","localhost");
          InitialContext ctx = new InitialContext(p);
          //Lookup the bean using it's deployment id
          Object obj = ctx.lookup("users/Hello");
//Be good and use RMI remote object narrowing
//as required by the EJB specification.
HelloHome ejbHome = (HelloHome) PortableRemoteObject.narrow(obj,HelloHome.class);
//Use the HelloHome to create a HelloObject
Hello ejbObject = ejbHome.create();
//The part we've all been wainting for...
String message = ejbObject.sayHello();
//A drum roll please.
System.out.println( " run successfully and message is :" + message);
} catch (Exception e){
e.printStackTrace();
I am able to compile but when i try to Run I get the following error message
javax.naming.CommunicationException. Root exception is java.lang.ClassNotFoundException: org.jboss.proxy.ClientContainer (no security manager: RMI class loader disabled)

Ejb reference not bound when calling a stateless bean in jboss

hi there !
i am trying to deploy a simple stateless session bean in Jboss3.0.4_tomcat-4.1.12
my bean is successfully deployed but when it is looked up in a jsp i am getting an exception as below :
javax.naming.NameNotFoundException ejb not bound
my ejb-jar.xml is as follows :
<session>
<display-name>FirstEJB</display-name>
<ejb-name>First</ejb-name>
<home>com.ejb.session.FirstHome</home>
<remote>com.ejb.session.First</remote>
<ejb-class>com.ejb.session.FirstEJB</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
jboss.xml is as follows:
<jboss>
<enterprise-beans>
<session>
<ejb-name>First</ejb-name>
<jndi-name>ejb/First</jndi-name>
</session>
</enterprise-beans>
</jboss>
my jsp is as follows :
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
props.put(Context.PROVIDER_URL,"localhost:1099");
props.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces" );
props.put("java.naming.rmi.security.manager","yes");
Context ctx = new InitialContext(props);
System.out.println("Before LookUp");
FirstHome home = (FirstHome)ctx.lookup("session.First");
System.out.println("LookUp Successfull");
First bean = home.create();
Can anyone fix this ?
Thanx in Advance

Hi,
hi Vicky !
thanx again for ur response.
i created a Demo.jar file as u said.
and now where should i place my JSP ?
first i will tell u my folder structure
<jboss-home>/server/default/deploy/index.war
index.war has the following
firstEJB.jsp
Web-inf/web.xml
Web-inf/jboss-web.xml
Web-inf/lib/First.jar
First.jar file has my home , remote , bean classes.
and ejb-jar.xml and jboss.xml files
web.xml has the <welcome-file-list>
jboss-web.xml has the <context-root>/</context-root>
plz tell me where i have messed up my code.
i have created the Demo.jar file now as u said.
so plz tell me where should i place my jsp file.
thanx
lakshmi
Since your application is having the jsp and ejb hence the deployment should be done as per the J2EE specification, where you have
1)web-module
2)ejb-module
3)appliction-client module
4)JCA(It is included in J2EE1.3+)
Now follow the following steps:
1)Demo.ear folder
2)Create META-INF/application.xml
3)Put your Demo.war and Demo.jar in Demo.ear
4)Demo.jar and Demo.war should be as expalined earlier.Also no need to place the ejb related classes in the WEB-INF/lib of Demo.war.
5)Write the following contents in the applicaiton.xml
<?xml version="1.0"?>
<!DOCTYPE application PUBLIC "-//Sun Microsystems, Inc.//DTD J2EE Application 1.2//EN" "http://java.sun.com/j2ee/dtds/application_1_2.dtd">
<application>
     <display-name>Project</display-name>
     <module>
     <ejb>
     Demo.jar
     </ejb>
     </module>
     <module>
          <web>
               <web-uri>Demo.war</web-uri>
               <context-root>/demo</context-root>
          </web>
     </module>
</application>
6)You can create the compressed form of ear or keep it exploded in the Jboss/server/default/Demo.ear
7)Note the console for the results of deplotment
8)call http://localhost:8080/demo/yourjsp.jsp
Hope now I have explained in the detail and it should work now.
Regards
Vicky

EJB Reference Not In IntitialContext

I have a jsp which accesses a stateless session bean which in turn accesses an entity bean.
The reference to the session bean is in the initial context but the entity bean reference is not (I have printed out the entire initial context to verify this).
When I deploy the application it does say that it is binding both the session bean and the entity bean.
(ie. binding "java:comp/env/ejb/<Name>" for both)
Any ideas as to why the ejb reference doesn't exist in the initial context?
FYI: I am using the J2EE app server and the deploy tool. I have checked the xmls and there is an ejb-ref in it for the entity bean.

You should say wheter the entity bean is referenced by the session bean, that is, in the deploytool:
1) select the session bean.
2) select the EJB Refs tab.
3) enter "ejb/YourEntityBean", "Entity" and the interfaces used. "ejb/YourEntityBean" should be as appears in your session bean code.
4) select the EJB jar. (the beans owner)
5) in the JNDI tab you will see this new entry in "References", here you put the JNDI name of your bean as appears bellow in "EJBs"

Deployed EJB Not Bound

I deplyed a simple EJB on S17AS. The server.log tells me it is deployed successful.
CORE3282: stdout: ejbCreate() on obj samples.jdbc.simple.ejb.GreeterDBBean@1017ca1
CORE3282: stdout: ejbCreate() on obj samples.jdbc.simple.ejb.GreeterDBBean@9d5793
LDR5010: All ejb(s) of [simpleEjb] loaded successfully!
The relevant simpleEjb.jar_verified.txt is as follows
     Test Name : tests.ejb.ias.ASEjbJndiName
     Test Assertion :
     Test Description : PASSED [AS-EJB ejb] : jndi-name is simpleHome
However, the server log did not indicate the EJB is bound even if I set the log level to finest.
Therefore when I tried to access it, I get the following error
Exception in thread "main" javax.naming.NameNotFoundException: No object bound f

I tried to use lookup for both "java:comp/env/ejb/simpleHome" and "java:comp/env/simpleHome". None succeed.
Does anyone know why the ejb is deployed successful but not bound?

Could not lookup PortalManagerHome in the JNDI tree using EJB reference java:comp/env/ejb/PortalManager

Hi
I am just a starter on WLPortal.
I have created a barebone Application from scratch. I have synchronized it properly
from EBCC to WLP. But When I am trying to access the home page of my application,
I am getting from stack trace -

Neeraj -
The Portal framework code (including PortalAppflowHelper) uses ejb
references to find the PortalManager (and other EJBs) from servlets and
taglibs; that is what is signified by the java:comp/env/... name.
Since you built your webapp from scratch (instead of using the portal
wizard), you will need to make sure the you have the appropriate
<ejb-ref> entries in your web.xml, and the corresponding
<ejb-reference-description> entries in your weblogic.xml. By default,
you will need at least mappings for:
- ejb/PortalManager
- ejb/UserManager
- ejb/GroupManager
- ejb/PipelineExecutor
- ejb/EventService
See either the resulting webapp from using the portal wizard or
BEA_HOME/weblogic700/samples/portal/sampleportalDomain/beaApps/sampleportal/sampleportal/WEB-INF
for example syntax.

EJB Reference could not be resolved (javax.naming.NameNotFoundException)

I am new to EJBs and am trying to get a simple Java client to run which I've generated from a EJB3.0 session bean.
The code for the client (LoanAppFacadeClient.java) is
package buslogic;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class LoanAppFacadeClient {
public static void main(String [] args) {
try {
final Context context = getInitialContext();
LoanAppFacade loanAppFacade = (LoanAppFacade)context.lookup("java:comp/env/ejb/LoanAppFacade");
// Call any of the Remote methods below to access the EJB
// System.out.println( loanAppFacade.getLoans( ) );
loanAppFacade.addLoan( "Galactic Loans", 30, "fixed", 6.25 );
String ssn = "123-12-1234";
System.out.println(loanAppFacade.getCreditRating( ssn ));
} catch (Exception ex) {
ex.printStackTrace();
private static Context getInitialContext() throws NamingException {
Hashtable env = new Hashtable();
// Standalone OC4J connection details
env.put( Context.INITIAL_CONTEXT_FACTORY, "oracle.j2ee.naming.ApplicationClientInitialContextFactory" );
env.put( Context.SECURITY_PRINCIPAL, "oc4jadmin" );
env.put( Context.SECURITY_CREDENTIALS, "welcome1" );
env.put(Context.PROVIDER_URL, "ormi://localhost:23791/LoanApp");
return new InitialContext( env );
When the trying to run the client I get a warning:
"WARNING: EJB Reference "ejb/LoanAppFacade" could not be resolved."
followed by the error
"javax.naming.NameNotFoundException: java:comp/env/ejb/LoanAppFacade not found in Lab1_BusinessServices-app-client"
When the client was created I right-clicked on the session bean (LoanAppFacadeBean which implements LoanAppFacade) and chose New Sample Java Client.
This automatically creates the java client and also created the following xml file (application-client.xml)
<?xml version = '1.0' encoding = 'windows-1252'?>

Could someone please help me to fix these errors?

I used windows for years whereby I stored all photos in folders. As macs don't use this concept I am finding it hard to organize my photos.
You can do this on your Mac too. Just don't use iPhoto. But iPhoto is a lot more flexible.
For instance:
I usually sort them by month so when I say move to an album I mean I create an album called for example '2013 March' so I can easily find specific photos/videos.
Click on the Magnifying Glass lower left to reveal the search box. Then click on the magnifying glass in the search box, and select Date. Now you can instantly find all the photos from a particular month, or day.
File -> New Smart Album will allow you to create an automatic album for any date or date range you choose.
Select one of the affected videos in the iPhoto Window and go File -> Reveal in Finder -> Original. A Finder Window should open with the file selected. Does it play?

Could be that your EJB is connected to a wrong datasource called only "jdbc"?
Strangely you say that while reading data all works fine (so the datasource definition is ok) but only when writing data there is a NamingException.
The stacktrace seems to report an error while getting datasource reference inside com.soluzionasf.arqw10.gc.cmp.OracleSequenceSessionLocal.getNextSequenceNumber method, the problems seems to be a bad name resource name ("jdbc" instead of java:jdbc/OracleDS or java:comp/env/jdbc/OracleDS if you use resource reference in your web.xml file). If you created this class as a CMP perhaps you misstype the right datasource name, otherwise if you code this method by yourseft you misstype the naming reference.

Error:CalculatorBeanRemote not bound

Hi Good People,
I am developing a sample EJB3 application in eclipse3.4. I am following the following steps:
1) First of all i am creating an EJB project (testEJB) in the eclipse. While creating this Project i am selecting the options of 1) Create an EJB Client Jar Module (testEJBClient) to hold the client interfaces and classes and 2) Add Project to an EAR (testEJBEAR) for this project. So it will create three different projects with the given names in the eclipse.
2) Now in the project testEJB i will create a stateless session bean. Its corresponding remote interface will be automatically created in the testEJBClient. Now i will declare a simple method hello() in the remote interface and will implement it in the testEJB.
So this completes my ejb beans.
3) Now in the third step i am creating a dynamic web project (with jboss as server). In this project's properties, in the java EE Module Dependencies section i am giving reference to both the testEJB.jar and testEJBClient.jar so that i can access the method in my jsp or servlets. My index.jsp is looks like:
<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page import="com.*, javax.naming.*,java.util.Properties"%>
<%
                       Properties p = new Properties();
                  p.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
                  p.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
                  p.put("java.naming.provider.url", "localhost");
                  Context ctx = new InitialContext(p);
                  calculator = (CalculatorBeanRemote)ctx.lookup(CalculatorBeanRemote.class.getName());
               System.out.println("Loaded Calculator Bean");
        } catch (Exception ex) {
            System.out.println("Error:"+
                    ex.getMessage());
%>But when i am trying to run this file it is giving the following exception :
Error:com.CalculatorBeanRemote not bound
I am trying to solve this from last 3 days but still not successful. If any one has any idea please help me.
I am also attaching the log file of jboss server.
Regards,
Khushwinder

I think your EJB's are not bound.
You can find this message when deploying the ejb server jar in the jboss app server.
And also check your web-inf/lib path for any jar files.
1.if your web-inf/lib contains the testEJBClient.jar(client jar) then remove it from there and place it in
jbosshome/server/default/lib
2.Place your testEJB.jar (server jar) in the deploy folder of jboss.similary your web app war file also place in the same location
by verifying the step1.
Don't use eclipse deployment. Manually place these jar files in the jboss and run the jboss in command prompt.
If you found in exception like binding then check your deployment packaging once again.
If you have any problem then ask me.
I hope it will solve your problem.

Venki

Access via 'NULL' object reference not possible Error in WD application execution

Experts,
I am getting following error for web dynpro application intermittently, please find following error log:
What happened?
    Error in the ABAP Application Program
    The current ABAP program "CL_SALV_WD_C_TABLE_V_TABLE====CP" had to be
     terminated because it has
    come across a statement that unfortunately cannot be executed.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
     caught in
    procedure "IF_SALV_WD_COMP_TABLE_DATA_MAP~MAP_TO_RESULT_CHANGES" "(METHOD)",
     nor was it propagated by a RAISING clause.
    Since the caller of the procedure could not have anticipated that the
    exception would occur, the current program is terminated.
    The reason for the exception is:
    You attempted to use a 'NULL' object reference (points to 'nothing')
    access a component.
    An object reference must point to an object (an instance of a class)
    before it can be used to access components.
    Either the reference was never set or it was set to 'NULL' using the
    CLEAR statement.
Information on where terminated
    Termination occurred in the ABAP program "CL_SALV_WD_C_TABLE_V_TABLE====CP" -
     in "IF_SALV_WD_COMP_TABLE_DATA_MAP~MAP_TO_RESULT_CHANGES".
    The main program was "SAPMHTTP ".
    In the source code you have the termination point in line 168
    of the (Include) program "CL_SALV_WD_C_TABLE_V_TABLE====CM080".
    The termination is caused because exception "CX_SY_REF_IS_INITIAL" occurred in
    procedure "IF_SALV_WD_COMP_TABLE_DATA_MAP~MAP_TO_RESULT_CHANGES" "(METHOD)",
     but it was neither handled locally nor declared
    in the RAISING clause of its signature.
    The procedure is in program "CL_SALV_WD_C_TABLE_V_TABLE====CP "; its source
     code begins in line
    1 of the (Include program "CL_SALV_WD_C_TABLE_V_TABLE====CM080 ".

Hi Madan,
It seems that, there are user settings saved and the attribute in the layout settings is not available with current changes.
try to delete the user settings if any.
Please find my answer in the below link

Hi jadespirit ,
I have the same problem in the same Book example ,my ejb3 project name "BaseHotele" so i follow what u said and this is my persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence>
<persistence-unit name="FirstEjb3Tutorial">
*<jta-data-source>java:BaseHoteleDS</jta-data-source>*
<properties>
<property name="hibernate.hbm2ddl.auto"
value="create-drop"/>
</properties>
</persistence-unit>
</persistence>
But it didn't work i have always HotelTestBean not bound!!
Help PLEASE i think that i had a mistake in the persistence.xml:i have 2 days searching for solutions without a good result!!!!!!!!!!!!!

Why to use EJB Reference

hi all,
when i have an enterprise application with a session bean and a webapp,
i can access the session bean either over an ejb-reference in the webapp or directly access the jndi entry. what is the advantage of using ejb references? here an example of what i mean (both from within a webapp):
ctx.lookup("myBean"); // without ejb ref
ctx.lookup("java:comp/env/ejb/myRef"); // with ejb ref
I get back the same, so whats the difference?
rgds

With ejb-reference a container optimizes access to collocated beans. For example, say you have a deployment where beans A and B are both replicated in two different containers, for performance and/or availability reasons. For optimal use every instance of A in container would use instances of B also in container one. Likewise for container two. An EJB container can enforce this locality constraint using ejb-links, but not always using direct JNDI names.
