Deploying EJB 3 session beans on OC4J 10.1.3.0.0 Standalone

Guys,
I am unable to deploy any EJB 3.0 session beans on my freshly installed OC4J 10.1.3.0.0 instance. I also have tried to deploy the EAR created by the "Develop a Stateless Session Bean using EJB 3.0" to eliminate problems in the deployed archive, but itfails with the exact same stacktrace:

Also, and this is probably related, when starting up it the app server prints:
6-06-05 14:38:51.777 WARNING J2EE EJB5003 EJB 3.0 enabled but JDK 1.5 is not in use. No annotations will be parsed.
Which is not true as I am running JDK 5.0_6 and I have tested/validated this by deploying a working (working as in putting stuff in and pulling stuff out of a db) EJB 3.0 Persistence project in there, which uses annotations.
I really hope somebody on the OC4J team can help me out on this, as I am guessing a lot of people will run into this.
Kind regards,
Mik

Well, I think I at least isolated the problem:
My installation was not as fresh as I thought. It had to do with my trying to get the latest version of TopLink (the final EJB 3.0 RI one) running on the latest OC4J standalone. For this I deleted the j2ee/home/persistence.jar and replaced it by toplink-essentials.jar. I apparently misjudged the differences that occured in the last steps of the EJB 3 specs.
So let me rephrase my question: is there a way to get the latest version of TopLink (the one packaged as the EJB3 Persistence RI) in the OC4J 10.1.3.0 Standalone container? And if not, when will there be one?

Hi,
I'm trying the "Oracle JDeveloper 11g Tutorials" - "Create a Simple EJB Session Bean", I just follow the instructions in that page. But when I tried to run it, it always failed. Can anyone help me to have a look. I paste the log below. thank you.
There's an error in the log "java.lang.ClassNotFoundException: oracle.security.jps.wls.listeners.JpsApplicationLifecycleListener". but I don't know what's that meaning.

Steve,
I'm facing the same issue as user#####.
Your workaround does not work ; when I deploy manuelly the ear file, with a new weblogic-application.xml, I get the same error.
Does that happen a lot ? :p

BC4J, JSP, accesing a remote app module deployed as an 8i EJB session bean

hi everybody,
i am reposting this question since the thread went somewhat off-topic ...
i have successfully deployed my Jdev 3.2 developed app module to my remote 8.1.7 db server as an EJB session bean
i am able to test it via the Business Components Tester ...
i am also able to test it from my wizard-generated Business Components JSP App using DataWebBeans ...
but when i try to access it from a JSP data tag page I get the following error:
Excepcisn:
javax.servlet.jsp.JspException: JBO-28300: Piggyback read error
void periodoswebtags_html.PeriodoView_Browse._jspService(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)

and the JBO-28300 error is undocumented ... :(
i have included a library containing the <mybcs>CommonEJB.jar and <myappmodule>EJBClient.jar files into my JSP projects
the JSP data tag page is a wizard-generated trivial browse page
TIA,

hi everybody,
just fixed ... :) ...
i added the following libraries to my JSP data tag project and everythig works fine ...
Oracle XML Parser 2.0
JBO Runtime

Deploying App Module as EJB Session Bean to JBoss

I am attempting to follow the How-To at
http://otn.oracle.com/products/jdev/howtos/appservers/deploy_bc4j_to_jboss.html for deploying BC4J to JBoss. In particular, I was looking at the section 'BC4J as an EJB Session Bean', because that is the route we would like to take.
The document instructs you to create a business components deployment profile.. ok, done.
It then instructs you to copy the app module configuration that was just created and rename it. However, the editor will not let you rename the configuration.
Then when 'Creating a JSP to Access Your Application Module as a EJB', the wizard to create the JSP will not allow you to select the app module configuration that was just created. It only shows the Local configuration.
What am I doing wrong? I am using JDeveloper 9.0.3.1.
My ultimate goal is to take an existing BC4J/JSP application and deploy the app module as an EJB, so the JSP and EJB can reside on separate machines.
Any pointers that anyone can give me about deploying an app module as a Session Facade (BMT) to JBoss, with a JSP front end, is greatly appreciated. I have read the how-tos available from OTN. I have relatively little experience with EJB, so please forgive me if there's something obvious I'm missing.
Thanks!!!

Can this be solved by application module pooling? How
can we use the PoolMgr to work with the session
beans?You can use a stateless checkout/checkin appmodule.
Take a look at the following help topics which explain this in good detail.
"About Application Module Pooling"
"About JSP Pages and Application Module Pooling"
The pool can help reuse the appmodule instance across requests thus reducing the number of concurrent db sessions.

How to deploy a BC4J application as a Session Bean to OC4J?

I want to deploy a BC4J application as an Session Bean to Oracle9iAS Containers for J2EE instead to the 9iAS-DB (= Oracle8i database). How to package the EJB JAR(s), EAR(s), Client JAR(s) ...???
The main question is: Is it generally possible to deploy/run a BC4J application as an Session Bean to/on Oracle9iAS Containers for J2EE???

One of the cool things about BC4J framework is the way you can deploy the BC4J application.
The BC4J application is independent of the deployment mode.
Irrespective of which mode you actually deploy the applicaiton, you would still get all the framework services.
It is also easily switchable from one deployment mode to another.
Today you can decide to deploy it in the local mode and a later stage if you need to deploy it as EJB Session Bean you don't have rewrite your Appplication.
All you do use the Design Time Wizards for the APplication Module and make it remotable as EJB Session Bean and everything is taken for you.
BC4J white paper available on technet gives more details

HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean

HOWTO: Using a BC4J Application Module in an Stateless EJB Session Bean
by Steve Muench
Overview
BC4J provides automatic facilities for deploying any application module as a stateful EJB session bean. If you want to leverage the features of your BC4J application module from a stateless EJB session bean, it's not automatic but it is straightforward to implement. This howto article explains the details.
For our example, we will create a stateless EJB session bean that uses a container-managed transaction. To keep things simple, let's assume the session bean has a single public method on its remote interface named createDepartment() with the following signature:
public void createDepartment(int id, String name, String loc) throws AppException
AppException is an example of an application-specific exception that our method will throw if any problems arise during its execution.The goal of this article is to illustrate how to use the BC4J application module named com.example.hr.HRApp as part of the implementation of this createDepartment method on our stateless enterprise bean. Let's assume that the HRApp application module has a view object member named Departments, based on the com.example.hr.DeptView view object, based on the familiar DEPT table and related to the com.example.hr.Dept entity object so our view can be updateable.
Creating the Stateless Session Bean
We can start by using the JDeveloper Enterprise Bean wizard to create a new stateless session bean called StatelessSampleEJB implemented by:[list][*]com.example.StatelessSampleEJBBean (Bean class)[*]com.example.StatelessSampleEJBHome (Home interface)[*]com.example.StatelessSampleEJB (Remote interface)[list]
We then use the EJB Class Editor to add the createDepartment method to the remote interface of StatelessSampleEJB with the signature above. We edit the remote interface to make sure that it also reflects that the createDepartment method thows the AppException like this:
package com.example;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
public interface StatelessSampleEJB extends EJBObject {
void createDepartment(int id, String name, String loc)
throws RemoteException,AppException;
}Before we start adding BC4J into the picture for our implementation, our StatelessSampleEJBBean class looks like this:
package com.example;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class StatelessSampleEJBBean implements SessionBean {
public void ejbCreate(){}
public void ejbActivate(){}
public void ejbPassivate(){}
public void ejbRemove(){}
public void setSessionContext(SessionContext ctx){
public void createDepartment(int id, String name, String loc)
throws AppException {
    // TODO: Implement method here
}We can double-click on the ejb-jar.xml file in our project to see the XML deployment descriptor for the bean we just created:
<ejb-jar>
   <enterprise-beans>
      <session>
         <description>Session Bean ( Stateless )</description>
         <display-name>StatelessSampleEJB</display-name>
         <ejb-name>StatelessSampleEJB</ejb-name>
         <home>com.example.StatelessSampleEJBHome</home>
         <remote>com.example.StatelessSampleEJB</remote>
         <ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Container</transaction-type>
      </session>
   </enterprise-beans>
</ejb-jar>We need to add the extra <assembly-descriptor> section in this file to indicate that the createDepartment method will require a transaction. After this edit, the ejb-jar.xml file looks like this:
<ejb-jar>
   <enterprise-beans>
      <session>
         <description>Session Bean ( Stateless )</description>
         <display-name>StatelessSampleEJB</display-name>
         <ejb-name>StatelessSampleEJB</ejb-name>
         <home>com.example.StatelessSampleEJBHome</home>
         <remote>com.example.StatelessSampleEJB</remote>
         <ejb-class>com.example.StatelessSampleEJBBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Container</transaction-type>
      </session>
   </enterprise-beans>
   <assembly-descriptor>
      <container-transaction>
         <method>
            <ejb-name>StatelessSampleEJB</ejb-name>
            <method-name>createDepartment</method-name>
            <method-params>
               <method-param>int</method-param>
               <method-param>java.lang.String</method-param>
               <method-param>java.lang.String</method-param>
            </method-params>
         </method>
         <trans-attribute>Required</trans-attribute>
      </container-transaction>
   </assembly-descriptor>
</ejb-jar>
Aggregating a BC4J Application Module
With the EJB aspects of our bean setup, we can proceed to implementing the BC4J application module aggregation.
The first thing we do is add private variables to hold the EJB SessionContext and the instance of the aggregated BC4J ApplicationModule, like this:
// Place to hold onto the aggregated appmodule instance
transient private ApplicationModule _am = null;
// Remember the SessionContext that the EJB container provides us
private           SessionContext    _ctx = null;and we modify the default, empty implementation of the setSessionContext() method to remember the session context like this:
public void setSessionContext(SessionContext ctx){ _ctx = ctx; }We add additional constants that hold the names of the J2EE datasource that we want BC4J to use, as well as the fully-qualified name of the BC4J application module that we'll be aggregating:
// JNDI resource name for the J2EE datasource to use
private static final String DATASOURCE = "jdbc/OracleCoreDS";
// Fully-qualified BC4J application module name to aggregate
private static final String APPMODNAME = "com.example.hr.HRApp";We expand the now-empty ejbCreate() and ejbRemove() methods to create and destory the aggregated instance of the BC4J application module that we'll use for the lifetime of the stateless session bean. When we're done, ejbCreate() it looks like this:
public void ejbCreate() throws CreateException {
try {
    // Setup a hashtable of environment parameters for JNDI initial context
    Hashtable env = new Hashtable();
    env.put(JboContext.INITIAL_CONTEXT_FACTORY,JboContext.JBO_CONTEXT_FACTORY);
    // NOTE: we want to use the BC4J app module in local mode as a simple Java class!
    env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_LOCAL);
    env.put(PropertyConstants.INTERNAL_CONNECTION_PARAMS,DATASOURCE);
    // Create an initial context, using this hashtable of environment params
    InitialContext ic = new InitialContext(env);
    // Lookup a home interface for the application module
    ApplicationModuleHome home = (ApplicationModuleHome)ic.lookup(APPMODNAME);
    // Using the home, create the instance of the appmodule we'll use
    _am = home.create();
    // Register the BC4J factory to handle EJB container-managed transactions
    registerContainerManagedTransactionHandlerFactory();
catch(Exception ex) {
     ex.printStackTrace();
    throw new CreateException(ex.getMessage());
}and ejbRemove() looks like this:
public void ejbRemove() {
try {
    // Cleanup any appmodule resources before getting shutdown
    _am.remove();
catch(JboException ex) { /* Ignore */ }
}The helper method named reigsterContainerManagedTransactionHandlerFactory() looks like this:
private void registerContainerManagedTransactionHandlerFactory() {
SessionImpl session = (SessionImpl)_am.getSession();
session.setTransactionHandlerFactory(
    new TransactionHandlerFactory() {
      public TransactionHandler createTransactionHandler() {
        return new ContainerManagedTxnHandlerImpl();
      public JTATransactionHandler createJTATransactionHandler() {
        return new ContainerManagedTxnHandlerImpl();
}The last detail is to use the BC4J appmodule to implement the createDepartment() method. It ends up looking like this:
public void createDepartment(int id, String name, String loc)
throws AppException {
try {
    // Connect the AM to the datasource we want to use for the duration
    // of this single method call.
    _am.getTransaction().connectToDataSource(null,DATASOURCE,false);
    // Use the "Departments" view object member of this AM
    ViewObject departments = _am.findViewObject("Departments");
    // Create a new row in this view object.
    Row newDept = departments.createRow();
    // Populate the attributes from the parameter arguments.
    newDept.setAttribute("Deptno", new Number(id));
    newDept.setAttribute("Dname", name);
    newDept.setAttribute("Loc", loc);
    // Add the new row to the view object's default rowset
    departments.insertRow(newDept);
    // Post all changes in the AM, but we don't commit them. The EJB
    // container managed transaction handles the commit.
    _am.getTransaction().postChanges();
catch(JboException ex) {
    // To be good EJB Container-Managed Transaction "citizens" we have
    // to mark the transaction as needing a rollback if there are problems
    _ctx.setRollbackOnly();
    throw new AppException("Error creating dept "+ id +"\n"+ex.getMessage());
finally {
    try {
      // Disconnect the AM from the datasource we're using
      _am.getTransaction().disconnect();
    catch(Exception ex) { /* Ignore */ }
Building a Test Client
With the EJB-Tier work done, we can build a sample client program to test this new stateless EJB Session Bean by selecting the bean in the Oracle9i JDeveloper IDE and choosing "Create Sample Java Client" from the right-mouse menu.
When the "Sample EJB Client Details" dialog appears, we take the defaults of connecting to embedded OC4J container. Clicking the (OK) button generates the following test class:
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import com.example.StatelessSampleEJB;
import com.example.StatelessSampleEJBHome;
public class SampleStatelessSampleEJBClient {
public static void main(String [] args) {
    SampleStatelessSampleEJBClient sampleStatelessSampleEJBClient =
       new SampleStatelessSampleEJBClient();
    try {
      Hashtable env = new Hashtable();
      env.put(Context.INITIAL_CONTEXT_FACTORY,
              "com.evermind.server.rmi.RMIInitialContextFactory");
      env.put(Context.SECURITY_PRINCIPAL, "admin");
      env.put(Context.SECURITY_CREDENTIALS, "welcome");
      env.put(Context.PROVIDER_URL,
              "ormi://localhost:23891/current-workspace-app");
      Context ctx = new InitialContext(env);
      StatelessSampleEJBHome statelessSampleEJBHome =
           (StatelessSampleEJBHome)ctx.lookup("StatelessSampleEJB");
      StatelessSampleEJB statelessSampleEJB;
      // Use one of the create() methods below to create a new instance
      // statelessSampleEJB = statelessSampleEJBHome.create();
      // Call any of the Remote methods below to access the EJB
      // statelessSampleEJB.createDepartment( int id, java.lang.String name, java.lang.String loc );
    catch(Throwable ex) {
      ex.printStackTrace();
}We uncomment the call to the create() method and add a few calls to the createDepartment() method so that the body of the test program now looks like this:
// Use one of the create() methods below to create a new instance
statelessSampleEJB = statelessSampleEJBHome.create();
// Call any of the Remote methods below to access the EJB
statelessSampleEJB.createDepartment( 13, "Test1","Loc1");
System.out.println("Created department 13");
statelessSampleEJB.createDepartment( 14, "Test2","Loc2");
System.out.println("Created department 14");
try {
// Try setting a department id that is too large!
statelessSampleEJB.createDepartment( 23456, "Test3","Loc3");
catch (AppException ax) {
System.err.println("AppException: "+ax.getMessage());
}Before we can successfully run our SampleStatelessSampleEJBClient we need to first run the EJB bean that the client will try to connect to. Since Oracle9i JDeveloper supports local running and debugging of the EJB-Tier without doing through a full J2EE deployment step, to accomplish this prerequisite step we just need to right-mouse on the StatelessSampleEJB node in the System Navigator and select "Run". This starts up the embedded OC4J instance and runs the EJB right out of the current out path.Finally, we can run the SampleStatelessSampleEJBClient, and see the output of the test program in the JDeveloper log window:
Created department 13
Created department 14
AppException: Error creating dept 23456
JBO-27010: Attribute set with value 23456 for Deptno in Dept has invalid precision/scale
Troubleshooting
One error that might arise while running the example is that the database connection information in your data-sources.xml for the jdbc/OracleCoreDS datasource does not correspond to the database you are trying to test against. If this happens, then double-check the file .\jdev\system\oc4j-config\data-sources.xml under the JDeveloper installation home directory to make sure that the url value provided is what you expect. For example, to work against a local Oracle database running on your current machine, listening on port 1521, with SID of ORCL, you would edit this file to have an entry like this for jdbc/OracleCoreDS :
<data-source
    class="com.evermind.sql.DriverManagerDataSource"
    name="OracleDS"
    location="jdbc/OracleCoreDS"
    xa-location="jdbc/xa/OracleXADS"
    ejb-location="jdbc/OracleDS"
    connection-driver="oracle.jdbc.driver.OracleDriver"
    username="scott"
    password="tiger"
    url="jdbc:oracle:thin:@localhost:1521:ORCL"
    inactivity-timeout="30"
/>This is the data-sources.xml file that gets used by the embedded OC4J instance running in JDeveloper.
Conclusion
Hopefully this article has illustrated that it is straightforward to utilize the full power of BC4J in local mode as part of your EJB Stateless Session Beans using container-managed transaction. This example illustrated a single createDepartment method in the enterprise bean, but by replicating the application module interaction code that we've illustrated in createDepartment, any number of methods in your stateless session bean can use the aggregated application module instance created in the ejbCreate() method.

Hi Steve, It4s me again;
About the question I made, I tried with a single assembly-descriptor tag and a single container-transaction tag in the deployment descriptor of the session bean and these were the results.
java.lang.NullPointerException
     void com.evermind.server.rmi.RMIConnection.EXCEPTION_ORIGINATES_FROM_THE_REMOTE_SERVER(java.lang.Throwable)
     java.lang.Object com.evermind.server.rmi.RMIConnection.invokeMethod(com.evermind.server.rmi.RMIContext, long, long, java.lang.reflect.Method, java.lang.Object[])

     void SamplemdeController.envolturaControlEJBClient.main(java.lang.String[])
Then I tried with multiple assembly-descriptor tags each with a single container-transaction tag and the results were:

Finally I tried with a single assembly-descriptor and multiple container tags and the results were:

How can I make my Stateless Session bean work out?

Can I deploy the session bean to 9i in the JDeveloper3.2

dear ONT
My JDeveloper3.2 can't find the method to deploy the session bean to 9i.
sk

I'm not sure that's entirely correct.
Personally I run both EJBs and servlets/JSP in OC4J. OC4J has all the 'web' features of IAS, including full SSL support.
From a speed perspective, running the EJBs and web components in the same container will give you a huge benefit.
Also I'm not sure what you mean by "you can't deploy EJBs into OC4J yet" - I do it daily? ;)

Test web service proxy using EJB session bean client...

Hello!
I am following this blog /people/abdelmorhit.elrhazi/blog/2009/10/30/how-to-consume-an-inbound-backend-web-service-in-nwdsjboss-environment to create a EJB session bean client to access the web service proxy...
The blog is not very clear. Where should I be deploying the web service proxy and the EJB session bean (web service client) ? on the PI 7.1 ?
How to find out the URL for the wsdl ?
Thanks

> The blog is not very clear. Where should I be deploying the web service proxy and the EJB session bean (web service client) ? on the PI 7.1 ?
"To deploy your web service proxy and session bean, right click on your JBoss server in the Servers view, and click on Add Remove Projects, add you ear file and click finish."
You need a JBoss server.

Unable to call exported client methods of EJB session bean remote interface

I am unable to call client methods of a BC4J application module deployed as a Session EJB to Oracle 8i at the client side of my multi-tier application. There is no documentation, and I am unable to understand how I should do it.
A business components project has been created. For instance, its application module is called BestdataModule. A few custom methods have been added to BestdataModuleImpl.java file, for instance:
public void doNothingNoArgs() {
public void doNothingOneArg(String astr) {
public void setCertificate(String userName, String userPassword) {
theCertificate = new Certificate(userName, userPassword);
public String getPermission() {
if (theCertificate != null)
{if (theCertificate.getPermission())
{return("Yes");
else return("No, expired");
else return("No, absent");
theCertificate being a protected class variable and Certificate being a class, etc.
The application module has been tested in the local mode, made remotable to be deployed as EJB session bean, methods to appear at the client side have been selected. The application module has been successfully deployed to Oracle 8.1.7 and tested in the remote mode. A custom library containing BestdataModuleEJBClient.jar and BestDataCommonEJB.jar has been created.
Then I try to create a client basing on Example Oracle8i/EJB Client snippet:
package bestclients;
import java.lang.*;
import java.sql.*;
import java.util.*;
import javax.naming.*;
import oracle.aurora.jndi.sess_iiop.*;
import oracle.jbo.*;
import oracle.jbo.client.remote.ejb.*;
import oracle.jbo.common.remote.*;
import oracle.jbo.common.remote.ejb.*;
import oracle.jdeveloper.html.*;
import bestdata.client.ejb.*;
import bestdata.common.ejb.*;
import bestdata.common.*;
import bestdata.client.ejb.BestdataModuleEJBClient;
public class BestClients extends Object {
static Hashtable env = new Hashtable(10);
public static void main(String[] args) {
String ejbUrl = "sess_iiop://localhost:2481:ORCL/test/TESTER/ejb/bestdata.BestdataModule";
String username = "TESTER";
String password = "TESTER";
Hashtable environment = new Hashtable();
environment.put(javax.naming.Context.URL_PKG_PREFIXES, "oracle.aurora.jndi");
environment.put(Context.SECURITY_PRINCIPAL, username);
environment.put(Context.SECURITY_CREDENTIALS, password);
environment.put(Context.SECURITY_AUTHENTICATION, ServiceCtx.NON_SSL_LOGIN);
BestdataModuleHome homeInterface = null;
try {
Context ic = new InitialContext(environment);
homeInterface = (BestdataModuleHome)ic.lookup(ejbUrl);
catch (ActivationException e) {
System.out.println(e.getMessage());
e.printStackTrace();
System.exit(1);
catch (CommunicationException e) {
System.out.println(e.getMessage());
e.printStackTrace();
System.exit(1);
catch (NamingException e) {
System.out.println(e.getMessage());
e.printStackTrace();
System.exit(1);
try {
System.out.println("Creating a new EJB instance");
RemoteBestdataModule remoteInterface = homeInterface.create();
// Method calls go here!
// e.g.
// System.out.println(remoteInterface.foo());
catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
It doesnt cause any errors. However, how must I call methods? The public interface RemoteBestdataModule has no such methods:
void doNothingNoArgs();
void doNothingOneArg(java.lang.String astr);
void setCertificate(java.lang.String userName, java.lang.String userPassword);
java.lang.String getPermission();
Instead of that it has the following methods:
oracle.jbo.common.remote.PiggybackReturn doNothingNoArgs(byte[] _pb) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn doNothingOneArg(byte[] _pb, java.lang.String astr) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn customQueryExec(byte[] _pb, java.lang.String aQuery) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn setCertificate(byte[] _pb, java.lang.String userName, java.lang.String userPassword) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn getPermission(byte[] _pb) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
I cannot call those methods. I can see how they are called in BestdataModuleEJBClient.java file:
public void doNothingNoArgs() throws oracle.jbo.JboException {
try {
oracle.jbo.common.remote.PiggybackReturn _pbRet = mRemoteAM.doNothingNoArgs(getPiggyback());
processPiggyback(_pbRet.mPiggyback);
if (_pbRet.isReturnStreamValid()) {
return;
catch (oracle.jbo.common.remote.ejb.RemoteJboException ex) {
processRemoteJboException(ex);
catch (java.rmi.RemoteException ex) {
processRemoteJboException(ex);
throw new oracle.jbo.JboException("Marshall error");
However, I cannot call getPiggyback() function! It is a protected method, it is available to the class BestdataModuleEJBClient which extends EJBApplicationModuleImpl, but it is unavailable to my class BestClients which extends Object and is intended to extend oracle.jdeveloper.html.WebBeanImpl!
It seems to me that I mustnt use RemoteBestdataModule interface directly. Instead of that I must use the public class BestdataModuleEJBClient that extends EJBApplicationModuleImpl and implements BestdataModule interface. It contains all methods required without additional arguments (see just above). However, how must I create an object of BestdataModuleEJBClient class? That is a puzzle. Besides my custom methods the class has only two methods:
protected bestdata.common.ejb.RemoteBestdataModule mRemoteAM;
/*This is the default constructor (do not remove)*/
public BestdataModuleEJBClient(RemoteApplicationModule remoteAM) {
super(remoteAM);
mRemoteAM = (bestdata.common.ejb.RemoteBestdataModule)remoteAM;
public bestdata.common.ejb.RemoteBestdataModule getRemoteBestdataModule() {
return mRemoteAM;
It looks like the remote application module must already exist! In despair I tried to put down something of the kind at the client side:
RemoteBestdataModule remoteInterface = homeInterface.create();
BestdataModuleEJBClient dm = new BestdataModuleEJBClient(remoteInterface);
dm.doNothingNoArgs();
Of course, it results in an error.
System Output: null
System Error: java.lang.NullPointerException

System Error: void bes
System Error: tclients.BestClients.main(java.lang.String[]) (BestClients.java:76)
I have studied a lot of documents in vain. I have found only various senseless discourses:
"Use the Application Module Wizard to make the Application Module remotable and export the method. This will generate an interface for HrAppmodule (HrAppmodule.java in the Common package) which contains the signature for the exported method promoteAllEmps(). Then, deploy the Application Module. Once the Application Module has been deployed, you can use the promoteAllEmps() method in your client-side programs. Calls to the promoteAllEmps() method in client-side programs will result in calls to the promote() method in the application tier."
However, I have failed to find a single line of code explaining how it should be called.
Can anybody help me?

How to pass parameter to the method in EJB session bean from Managed Bean

Hi,
I need some guidance in accessing the EJB session bean methods from one of my backing Bean. I use EJB 3.0 Entity Beans and EJB Session Beans. I have to get value from my page and pass it thro the backing bean to the respective EJB session bean. I have no clue of how to do this,
When i click a command link on the page, in its backing bean click method, i am able to get a value and store in a variable under its click action. But from there i am not knowing of how to pass it as a variable to the EJB session bean and hence execute the query(this is where we have to pass the variable as a parameter in its where clause) in the entity bean.
I wanna know how to make a call to the EJB session bean and from there execute the Enitity bean.
Guide me regarding this....
Thanks
ri

Unfortunately dependency injection doesn't work for jsf backing beans, so you have to use a normal jndi lookup to find your session bean. The following example shows you how to find a session bean and call a method:
public void commandButton_actionListener(ActionEvent actionEvent) {
Context ctx;
try {
ctx = new InitialContext();
helloWorldEjb = (HelloWorldEJB)ctx.lookup("HelloWorldEJB");
hello = helloWorldEjb.sayHello(name);
System.out.println(hello);
} catch (NamingException e) {
e.printStackTrace();
}

EJB Session Bean in Java Studio Creator

Hello!
I just download the creator 2, and imported some of my EJB that i created with Sun Application Server. It sounds like that the import was successful and i can see my files under EJB in servers windows. I am creating some form with creator and i like to use EJB Session bean to transform the data that the form is submitting.
Any idea or suggestions

After you drop an ejb into the designer, you'll see a <ejb>Client1 instance created for the ejb in the backing bean (i.e. Page1.java). The client instance is a wrapper for the ejb. It contains all the remote methods available on your ejb. In your web app, you can invoke any methods on the client instance as if you're calling methods on a regular java object. The wrapper class knows how to invoke the corresponding methods on the ejb for you.

How to pass submitted Data from a servlet to EJB Session Bean in JPA

How to pass Data User submitted Data from a servlet to EJB Session Bean when using JPA :
Hi ,
I have a jsp page in which the user fills up the Data and submits it to the servlet :
Inside servlets i am getting all the parameters and setting it to the Entity Class .
Sample Entity class is shown below :
@Entity
public class Employee {
@Id private int id;
private String name;
public Employee() {}
public Employee(int id) { this.id = id; }
public int getId() { return id; }
public void setId(int id) { this.id = id; }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
}After calling setters of my Entity Class .
I am using JNDI lookup to call my session Bean method and pass this Entity class to the session Bean to persist data
Please let me know what will be the right approach :
1. Passing parameters whole as a Entity Class
that is
public void insertData(Employee emp)
}Or
2. public void insertData(String Name , int ID)
}

they are both right as they both work. Easy huh?
You might argue that if you have to set a lot of fields, use the entity as otherwise you get a method with a gigantic amount of parameters.

Create Data Control not showing in EJB Session Bean context menu

Hi All,
I've been studying the new Oracle Application Development Framework Tutorial for 10g Release 3 (10.1.3). When I get to page 2-16 (page 31 of the PDF doc) it says to create ADF Data Control. Specifically is says " In the Applications Navigator, right-click the SRPublicFacadeBean.java node and choose Create Data Control from the context menu."
But my context menu doesnt have the Create Data Control option. I double checked that I didn't miss a step in the tutorial. I'm sure it's something simple. Can anyone point me in the right direction? Is there another way to create the Data Control for an EJB Session Bean?
Thanks,
Cary

I downloaded "jdevstudio1013.zip " and I still don't have this context menu?
What are the steps to correct this?
Thanks,
--Todd
Figured it out. I was having an extension issue and I had to turn off all of my extensions. Thus, turned on the ADF extension (duh!) and all was well.

JDev 10.1.3: Problem deploying a session bean to embedded OC4J

JDeveloper 10.1.3, TopLink, OC4J, WinXP, java 1.4.2_05.
I used TopLink to create a set of Java objects from a DB Schema, then created a simple Session Bean to read some of the objects. Everything compiles fine.
JAVA_HOME points to the JDK (not JRE) and CLASSPATH is empty (undefined).
When I try to Run my session bean in the jdeveloper embedded oc4j, I get this message. Thanks in advance for your help.
