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)

void oracle.lite.web.SocketListener.process(java.net.Socket)
void oracle.lite.web.SocketListener$ReqHandler.run()
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
SQLJ Runtime
HTH,

App No Longer Works After Creating EJB Session Bean

I am using EJB3.0 and using JDEV 11g, PS1. I have used EJB to create my entities from tables and then i created my ejb diagram. After doing that my application (i have a jspx page) that runs fine. Once I create my session bean, I am no longer able to run my application. After creating my session bean I get the following error when I run the application (i.e. not at build/compile time).
<Feb 12, 2010 3:28:57 PM PST> <Error> <Deployer> <BEA-149265> <Failure occurred in the execution of deployment request with ID '1266017332257' for task '5'. Error is: 'java.lang.ClassNotFoundException: javax.faces.webapp.ConverterELTag'
java.lang.ClassNotFoundException: javax.faces.webapp.ConverterELTag
If i delete the sessionejb.java, ejbbean.java, and the ejblocal.java files, I am able to run my application again. Am I missing something or is this a bug?
Thanks.

Did you solved the problemn? I'm getting this, when I try run my App doesn't work, but if I deploy to WLS Integrated and go to URL it's work...

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.

BC4J: client object reference in app module

We know that the BC4J clients can call the server using the remote app module reference. Just wondering if the server can have references to the clients as well (so that the server could call all the clients if something on the server gets updated)? If so, is there any example for client callbacks from the app modules? Has anyone done something like this before?

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[])
     java.lang.Object com.evermind.server.rmi.RemoteInvocationHandler.invoke(java.lang.Object, 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:
java.lang.NullPointerException

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?

Always fail to deploy to server when (Create a Simple EJB Session Bean )

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

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:

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.

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?

Deploy Error when using Stateful Session Bean inside Webdynpro

Hi,
I'm trying to create a webdynpro project that uses a stateful session bean
I have created DC's for a EJB Module project, Enterprise Application and Webdynpro component. Created the bean, built it, added it's package to the public part, added the EJB Module to the EAR project. Built the EAR project. Added the EJB Module project and Enterprise Application project as a used DC in the Webdynpro DC.
In the Webdynpro DC I added com.sap.archive-packaging.default.update-descriptors=true in the build.properties file of the cfg directory. (using the navigator view) That resolved an error while building it.
Deployed the Enterprise Application DC without problems.
Tried to deploy the Webdynpro DC but I get the following error:

Default is 30mts.
This is done as a parameter in orion-ejb-jar.xml. Please look at the EJB Guide at http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/a97677/dtdxml.htm#634197 for details

HOW CAN I DEPLOY BC4J JSP APPLICATION ON REMOTE OC4J?

Hi,
I am using JDeveloper9iRC. I am trying to go through 'Oracle9i JDeveloper Reviewers Guide'. After having built business components and a JSP front-end I would like to deploy my application on remote OC4J (release 2). I started with the deployment of the middle-tier components as an EJB. It was a success, but I had to add the following line to application.xml file (because of JBO-28300: Piggyback read error):
<library path="../../home/lib/bc4jdomorcl.jar" />
I also deployed the JavaServer Pages as Web Module - WAR. When I am trying to access the web application in a browser
(http://hostname:8888/j2eeapp-3JSP-context-root/
OrdersView_BrowseEdit.jsp) I get an empty page. However, locally it works.
It looks like something wrong was with 'datatags.jar' library.
Is the following tag correct, if I have business components in different project than JSP:
<jbo:ApplicationModule id="am" configname="bizlogic.BizlogicModule.BizlogicModuleLocal" releasemode="Stateful" />?
I would be grateful for every advice.

hy wang.
to deploy a simple jsp-project create a deployment-profile (WAR-File) in this project. -->file-->new-->deployment-profiles-->war.
now you need a connection to the oc4j where you want to put your files. this can be done in the system-navigation of jdev.
you then can rightclick the <myapp>.deploy and deploy the project to a selected oc4j.
don't forget to have a look at the jdev-help.
hope this helps you for the first.

Remote App - Because of a protocol error this session will be disconnected

Hello,
We have an environment where we connect to our server in a different network location to access our ERP system. On this server, we have a RemoteApp configured, so the connection is transparent to the user.
We connect to this different network location through a VPN tunnel (in this VPN tunnel, we already have a compression configured). So the Microsoft RDP do not compress the connection, I have configured the server with the recommended settings. When I open
just one instance of the software, it works perfectly. The problem happens when I open more than one instance of the software or let's say a software Help (F1). Two screens show as opened and when I try to navigate from one to another, it gives me the error.
Below you can find an image that illustrates what I am calling two instances of a software. I have created a simple WordPad Remote Application to check whenever the problem was directly involved with my ERP RemoteApp or any of them. With the WordPad application,
the problem also occurs.
http://social.technet.microsoft.com/Forums/getfile/502716
I have tried several different configurations (but the ones that should work are listed below) and also tried to check the
Event Viewer. Unfortunately, none work.
The following steps were used to disable encryption on Windows virtual desktops
Registry keys:
• Set HKLM\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\MinEncryptionLevel to 1.
• Create HKLM\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\SecurityLayer as a DWORD
value and set it to 0.
Disabling Compression and changing Authentication Level:
Step 1. Open the RDP connection (.rdp) file in Notepad.
Step 2. Change the line compression:i:1 to compression:i:0.
Step 2. Create a new line with authentication
level:i:0.
Step 3. Save the file.
Thank you,
Pedro Pagliosa

Unable to deploy an EJB session Bean

I run with JDeveloper 3.1, Oracle8.1.6 on windows NT.
All steps to deploy the Business Logic Tier work fine except the last one when to deploy
using the deployment profile; I' ve got the following error in the debug window:
(last lines of the debug)
Generating Jar File...done
Loading EJB Jar file and Comm Stubs Jar file...done
Generating EJBHome and EJBObject on the server...
An exception occurred during code generation: Class not found: DpltBcPkg.common.ejb.DpltBcPkgModuleHome.class
*** Errors occurred while deploying the EJB to JServer ***
*** Deployment completed ***
Help will be greatly appreciated, thanks in advance

Jean-Yves,
The class that the deployment wizard can't find should have been created when you made your application module remotable. So you should check the following:
- Did you make your application module remotable? (edit the application module and select the "Remote" tab; complete instructions are in the online help).
- Did you rebuild your application after making your application module remotable?
When you make your application module remotable, the node for Common->ejb->DpltBcPkgModuleHome.java should show in the navigator pane.

Problem in Connection pooling after deploying BC4J App Module as EJB

Hi,
We have deployed the application modules on standalone OC4J as stateful EJB session beans.
The problem is that with each user, the number of database connections seem to increase. This is making the application unscalable, which defeats the purpose of using EJB!
Can someone please suggest how to limit the number of database conections in this scenario?
Can this be solved by application module pooling? How can we use the PoolMgr to work with the session beans?
We have tried to invoke disconnect on the application module after calling methods(using appmodule.disconnect(true)) and reconnect (appmodule.reconnect()) on entering the method. This keeps the number of connections low and works the first time the method is invoked. But subsequently, it gives nullpointerexception when the Row is accessed in the JSP.
The exception we are getting is :
java.lang.NullPointerException

          xa-location="jdbc/xa/ConnectionXADS"
          max-connections="5"
          min-connections="1"/>

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.

BC4J:jsp:deployment

I implemented a Jsp application based on BC4J and I want to deploy it to the server.
as shown in the Jdeveloper Help; first I have to deploy the BC4J as Oracle8i EJB Session Bean. but the problem is that I don't know how to establish an IIOP connection. My question is can I deploy the BC4J project as an Oracle application server; and so I have not to specify aN IIOP connection.
any help is appreciated.

You have to pre-config the standalone oc4j with BC4J installer to setup the bc4j runtime on the oc4j.
