Deploying EJB 3.0 entity beans without a Datasource

[Cross-posted from the TopLink list]
My question: Is there any way to configure the container or persistence provider to defer trying to connect to the Datasource until I make some call that involves persistence? Or any other way to deploy an app containing entity beans without having a database configured?
Background: I am working on a component that can be configured to run in either persistent or in-memory mode. For the persistent mode we would like to use EJB 3.0 entity beans; for the in-memory mode we would like the component to be deployable without having to have a database available.
However in my prototype of the application, when I try to deploy to OC4J 10.1.3, as soon as the entity beans are detected the TopLink persistence provider tries to establish a connection to the db via either the configured or default DataSource. So if the db is unavailable, deployment fails. Since this is occuring at deployment, it happens regardless of whether I am actually using any persistence features or not.

Hi,
I'm experiencing same problems, is this a bug or an feature?

Deployment descriptor error for an EJB 3.0 entity bean module

Hi all,
i'm facing an error deploying an EJB 3.0 entity bean module wrapped in an enterprise application on WebLogic 10.
The application is composed as follows:
WASEnterprise.ear
|-META-INF
|-application.xml
|-WAS.jar
|-META-INF
|-persistence.xml
In other words the application server is unable to load persistence.xml deployment descriptor and,during deployment, it throws an error message like this:
<Error> <J2EE> <BEA-160197> <Unable to load descriptor C:\bea\user_projects\domains\base_domain\autodeploy\WASEnterprise\WAS/META-INF/persistence.xml of module WAS. The error is weblogic.descriptor.DescriptorException: Unmarshaller failed
I suppose that the persistence.xml is correct since i can deploy the application on jboss without any problem.
The persistence.xml deployment descriptor is:
<?xml version="1.0" encoding="UTF-8"?>

I don't use any other weblogic specific deployment descriptor.
Have you ever experienced such a strange behaviour? Can you suggest something to solve the problem?
Thanks inadvance.

Problems accessing ejb 3.0 entity bean from project

I have written some code using ejb 3.0 and was previously accessing the entity bean without problem when both ejbs and the accessing code were in the same project. However I have moved the accessing code into a different project within the same application and now when the code tries to accessing the entity bean I get the following error:
com.colwilson.web.ingestion.IdentifiedException: java.lang.ClassCastException: __Proxy3
     at com.colwilson.web.ingestion.IngestionHandler.recordArrived(IngestionHandler.java:140)
     at com.colwilson.web.ingestion.IngestionHandler.main(IngestionHandler.java:52)

     ... 1 more
Now, of course I could move the code back into the same project, but as I understand it that is just the point of ejbs. I'm looking up the entity bean thus:
final Context context = InitialContext();
ingestionSessionEJB =
(IngestionSessionEJB)context.lookup("IngestionSessionEJB");
It may be true that I don't understand the way lookup works, but to be honest I can't find the docs that explain what I've got wrong.
Please help.

hi
Double Click on the project which is goin to use the project which contains bean from the Application Navigator window. The project properties window will open. Choose the "Dependencies" item from left panel. click on the radio "User Project Settings" and select another project which contain ejb which you're goin to access...

EJB 3.0 Entity Bean

Hi Friends,
I am Facing a problem in EJB 3.0 Entity Bean. I am Using Eclipse 3.3.2 and JBoss 4.2 Application Server. Im getting the error such as *"javax.naming.NameNotFoundException: EntityBean not bound"* when im trying to lookup the entity bean. Herewith i had attached the servlet code. Can anyone suggest me.
package common;
import java.io.IOException;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import example.BookRemote;
public class CounterServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {
static final long serialVersionUID = 1L;
private BookRemote hello;
     public CounterServlet() {
          super();
     protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          // TODO Auto-generated method stub
          try
     InitialContext ctx = new InitialContext();
     hello = (BookRemote) ctx.lookup("EntityBean/remote");
     hello.test();
     Integer count = 1;
     request.setAttribute("counter", count);
     request.getRequestDispatcher("result.jsp").forward(request, response);
     catch (NamingException e)
     e.printStackTrace();
     protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          // TODO Auto-generated method stub
     }

I think the Bean haven't been registered. I had look into the jmx-console and this is the result which i have got for my sample application (EntityBean).

Ejb 3.0 Entity Bean Deployment

I am using Jboss4.0.4 Application Server and i have deployed the Entity bean.
In this for every request with same primary key, it is getting the values from the data base every time. I am not able to figure out why it's behaving like this.. Is there is any thing through code we can instruct the container to do it.

EJB 3.0 entity beans and WebDynpro models

Hi all,
first off all my setup:
WebDynpro Development Component: dcA
EJB Module Development Component: dcB
i wan't to create Entity Beans in dcB an use it for my model in dcA.
My questions:
1. Why does the "New Wizard" only offer EJB 3.0 Session and Message Beans an no Entity Beans? What is the correct way for creating Entity Beans in DevStudio?
2. Is ist right that i have to define a public Part containing the Entity Bean to make it visible to dcA?

Problem creating EJB 3.0 Entity bean in JDeveloper

Hello all,
I trying to create my first entity bean in JDeveloper.
JDevelper create the entity bean with the code below:
package model;
import java.io.Serializable;
import javax.persistence.Entity;
@Entity
public class BatchSettlementT implements Serializable {
public BatchSettlementT() {
The problem is that JDeveloper don't find the import command import javax.persistence.Entity;
What am I doing wrong?
I'm using JDeveloper Studio Edition Version 10.1.3.1.0.3914.
My libraries are:
- TopLink
- Oracle XML Parser 2
- EJB 3.0
- Toplink Essentials JPA
- J2EE
Thanks in advance.

It's very strange, when I type import.javax. in my class there is no persistence package available, do you have any idea what's wrong.
I did set the technology scope to EJB either.
Thanks!

Problem with ejb 3.0 entity beans with manyToMany relationship

Hello everyone!
I am using struts 1.2.9 and java ee 5 sdk update 2 for my enterprise application. Besides others i have these entity beans Targetgroup.java and City.java, (i would upload file but i do not know how:)
with manytomany relationship with join table.
when user updates Targetgroup, by clicking on web page with checkboxes and textfields, struts dispatch action calls following method stateless bean:
public void update(String firmId, String targetgroupId, String newGender, String newMinYearsOld, String newMaxYearsOld, String[] newCities) {
TargetgroupPK pkForUpdate = new TargetgroupPK(targetgroupId, firmId);
Targetgroup targetgroupForUpdate = find(pkForUpdate);
targetgroupForUpdate.setGender(newGender);
targetgroupForUpdate.setMinyearold(Integer.parseIn t(newMinYearsOld));
targetgroupForUpdate.setMaxyearold(Integer.parseIn t(newMaxYearsOld));
//pronalazenje gradva za koje je vezana ciljna grupa
Collection<City> newCitiesCollection = new ArrayList<City>();
for(int i = 0; i < newCities.length; i++){
String tmp_city_name = newCities;
City city_obj = cityFacade.find(tmp_city_name);
newCitiesCollection.add(city_obj);
targetgroupForUpdate.setCityidCollection(newCities Collection);
parameter newCities represents names of cities which user checked on his update page. When the page is showen to him some cities are allready check because they were connected with Targetgruoup when it was created (targetgroup).
this code throws following exception:

exceprion is throwen ONLY when in parameter newCities are city names allready connected to Targetgroup. when NewCities contains names of
City objects which are not connected to Targetgroup it works fine, but it's of no use for me, because user must be able to add or remove certian cities from relaionship with Targetgroup. I think it's because there are rows in join table that contain primary keys of city and targetgroup which are connected so perisistence manager cann't write them again.
i thought it was going to figure it out by itself, and only update those rows.
Does anyone know what is the problem and solution?
Thanks! (forgive my spelling errors :)

solved the problem!
I moved code from sesion bean to struts action as follows:
CityFacadeLocal cityFacade = lookupCityFacade();
//prikupljanje novih podataka o ciljnoj grupi
String newGender = ctf.getGender();
String newMaxYears = ctf.getMaxyears();
String newMinYears = ctf.getMinyears();
String[] newSelectedCities = ctf.getSelectedCities();
//niz imena gradova se prevodi u kolekcju objekata City
Collection<City> newCitiesObjCollection = new Vector<City>();
for(int i = 0; i < newSelectedCities.length; i++){
String tmpCityName = newSelectedCities;
City tmpCityObj = cityFacade.find(tmpCityName);
newCitiesObjCollection.add(tmpCityObj);
//setovanje novih podataka
targetgroupForUD.setGender(newGender);
targetgroupForUD.setMinyearold(Integer.parseInt(newMinYears));
targetgroupForUD.setMaxyearold(Integer.parseInt(newMaxYears));
targetgroupForUD.setCityidCollection(newCitiesObjCollection);
//pozivanje update metdoe u session beany
targetgroupFacade.edit(targetgroupForUD);
//korisnik se vraca na stranu sa svim postojecim ciljnim grupama
forward = mapping.findForward("backend.targetgroups");
and now it works fine. I guess probelm was same transaction scope for Targetgroup and City entities. Now when they are separated it works.
Thanks!

@EJB annotation in entity bean does not work

I just started with ejb3. I have created a couple of beans. One session bean that looks like this:
@Stateless
public class MySessionBean implements MySession
     @Resource(name="jdbc/mydb")
     private DataSource myDB;
public void someMethod() {
myDB.getConnection()
This works great. The other bean is an entity bean, and there the resource injection doesn't work. It looks like this:
@Entity
public class MyEntityBean
@Resource(name="jdbc/mydb")
     private DataSource myDB;
public void someMethod() {
myDB.getConnection()
Is resource injection any different in an entity bean then in a session bean? Both beans belong to the same package and are in the same application, (ear). I have exactly the same problem with @EJB injection: it works fine in the session bean but not in the entity bean...
Any help is appreciated...

Creating and deploying ejb 3.0 session bean with annotated pojo

I try to create and deploy a EJB 3.0 stateless session bean (and associated webservice) with the following steps:
1) Create Interface "Repository"
package de.xxx.config;
import java.rmi.Remote;
import java.rmi.RemoteException;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public interface Repository extends Remote {
     @WebMethod(operationName = "findCampaignByChannel")
     public String findCampaignByChannel(String channelName) throws RemoteException;
2) create dummy "RepositoryImpl"
package de.xxx.config;
import java.rmi.RemoteException;
import javax.ejb.Stateless;
import javax.jws.WebService;
@WebService(endpointInterface="de.xxx.config.Repository")
@Stateless
public class RepositoryImpl implements Repository {
     public String findCampaignByChannel(String channelName) throws RemoteException {
          return null;
3) The two class files are packaged into a jar without any further descriptors
4) The jar is deployed with admin_client into the oc4j instance using the commands:
-deploy -file <jarfile> -deploymentName <name>
Result:
An ear was constructed and started but no session bean or webservice is found (using the console). But according to to the docs a jar file without a ejb-jar.xml should be recognized as a EJB 3.0 ejb-jar file and the necessary steps to create session bean and expose webservice should be done automatically.
My question:
Which step do i miss here ?
Tools used:
Eclipse 3.2 for the jar file
SoaSuite 10.1.3.1 for oc4j

another strange problem.
i have an APplication server added ( JBOSS ).
when i create deployment profile (EAR ) application server is showed in the ComboBox .
But when i create Java Test Client for some EJB and when i check " Connect Remote Application server" there is 2 comboboxes
J2EE Application
App Server Connection.
first combo is ok there is EJB applicaiton
Secound is empty .. but i Have App Server.
Another think is that when i create EJB 3.0 its BAD to see J2EE app it must be J EE 5 app or just Java EE app

Deployment fails when my entity Bean has the following NamedQuery.

Hi Folks,
I have and entity that has the following NamedQuery
@NamedQuery(name = "myQuery", query = "SELECT o FROM HELLOWORLD o WHERE BINARY o.bName LIKE :bName and o.AK = :AK"),
The EAR that contains this Entity is not getting deployed. It fails with the following error. Any Ideas ?..

Hi SpaceShuttle,
the valid jpql keywords can be found in the ejb 3 persistence specification. You can download it form here:
[http://jcp.org/aboutJava/communityprocess/final/jsr220/index.html]
Btw. if you try to enforce case sensitive comparison on your columns you must define them using the appropriate collation.
For example
@Column(columnDefinition="varchar(200) COLLATE latin1_bin")
should work.
This way you won't need the BINARY keyword at all.

EJB, JPA E MANAGED BEAN WITHOUT DATA CONTROL

How do I build a simple crud with no EJB without data controls. Exposing the methods of my bean class.
Who can help me thanks.

You'll write managed beans that access your EJB service facade.
You can use @EJB injection to get this working.

EJB/JPA Session/Entity Bean: Back Reference Id not set

Hello All,
I m using JPA as a persist tool. I have an entity Account and in Account there is a collection of entity AccountDetail. In Account entity relation for AccountDetail is One-To-Many and in AccountDetail the relation for Account is Many-To-One. When i save the Account, object of Account and AccountDetail are saved correctly. But the problem is that in AccountDetail the Id of Account is not saved in Database table. I have AccountId in AccountDetail table. plz help me??
Second thing is that how to generate automatically primary keys when entity saved in database ???

define the column you want to auto increment as an Integer with Identity attribute set to True (using the sql server management tool for example) and then put
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
in front of the ID declaration in the mapping file, it should generate the IDs automatically.

EJB 3.0 entity beans generation with MySql - problem

Hi,
I am using JDev 10.1.3 Production and using the EJB3.0 CMP wizard to generate the code from a MySQL database. No matter what type I specify for my database columns in schema, code generator always generates the properties of type String only. e.g if a column called Age is specified as Integer in schema, the generator generates setters/getters with String type.
Can somebody please help me.
Regards
Vimal
