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.

Strange Session/Entity Bean Cross-Instance Calls in Cluster

In one of our enviroments, we are seeing session entity bean cross-instance
          calls that are hard to explain. The following is our configuration:
          The cluster contains 4 instances on 2 machines (2 on each machine). The same
          beans are deployed to each instance. "jndi.properties" is on the classpath
          for the each instance with jndi provider url = mach1inst1-ip, mach1inst2-ip,
          mach2inst1-ip, mach2inst2-ip:70001. Same servlets are also deployed to each
          instances.
          Requests from the web are load balanced through weblogic's proxy plugin for
          IPlanet and are forwarded to the 4 weblogic cluster instances. The servlet
          processing the requests calls a stateless session bean which uses an entity
          bean. The entity bean is configured with "home-is-clusterable" set to
          "false".
          What we have observed is that when all 4 instances are up, sometimes (even
          when the load is not high) the session bean is accessing entity bean from an
          instance on one machine to an instnace on another machine, while if only one
          machine (with 2 instances) is up, we don't see such calls.
          My theory is that because the jndi provider url is the same for all
          instances, the jndi lookup from each instance goes to the instance bound to
          the first IP specified in the provider url: machine 1 istance 1. If the
          request is from machine 2, because of co-location optimization, even though
          the home stub is from machine 1 instance 1, the session bean returned from
          the home stub actually is from machine 2. However, when the session bean
          does jndi lookup to get an entity bean home, the home stub is from machine 1
          and instance 1. And unfortunately, because the entity bean home is not
          clusterable, the stub can only point back to machine 1, co-location can not
          work. Thus entity bean from machine 1 is referenced by the session bean
          located on machine 2. I do not have a chance to verify this. But it seems to
          make sense to me.
          Unfortunately, I don't feel that I have a theory to explain why we don't see
          cross instance session entity bean calls when only 1 machine is up (with 2
          instances).
          Any ideas or hints would be greatly appreciated.
          Thanks,
          David Chen


rs = stmt.executeQuery() , insert statement is not a query. So use executeUpdate.

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).

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:

Have you ever experienced such a strange behaviour? Can you suggest something to solve the problem?

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?

I took my iMac to be fixed and when i got it back, mail was not set up. I called Apple Support and they helped me set up mail. Then the emails went to trash on the iMac and on the MacBook Pro (same emails). There are no numbers by the 'inbox' to tell how

I took my iMac to be fixed and when I got it back, mail was not set, so I called Apple and they helped me set up mail. Now the new mail goes to trash and there is no number by the 'inbox' to tell me how many new messages I have. I cannot save a draft to 'drafts.' There is a large number by 'trash' (I think all mail went to trash - including drafts). When I send myself an emai, it goes to trash also. This is on both my iMac (the one taken in) and my MacBook Pro (same emails) which was not taken in.
I went to 'rules' but have no idea what to do there. There are no rules in the rule box. When I click 'add rule' it puts 'rule 1' in the rule box, but since that was not there when I took it in, I delete it to have an empty rule box.
Can someone pleasehelp me. I am completely stupid with all this. Do not under stand what is suppose to be set up in 'rules.'
Thank you so much,
Arudi

Now new mail is coming to both computer's inboxes but there is no number on the stamp icon on dock to show number of emails on the iMac. Nor is there a number by either email address under MAILBOXES/inbox (sidebar) on the iMac. This number is showing on MacBook Pro.
I also can save drafts now on both computers.
Seems the Pro is fixed and the iMac is only missing the numbers on dock icon and by addresses in inbox.
Now that the problem is less, I feel i am wasting your time but will continue so maybe I can get those numbers back.
Two emails > AT&T email and gmail.
Apple's Mail program for email - yes, and gmail.
IMAP for both accounts.
Did not change mail configuration on MacBook.
The iMac and MacBook Pro have the same mail configuration except in Accounts/mailbox behaviours/store draft messages on the server was not marked on MacBook > it is now.
'Store junk messages on the server' was marked on one computer for gmail, but is unmarked on both now.
On the iMac, Accounts/Accounts info/Outgoing mail for gmail is smtpgmail.
On the MacBook Pro for gmail it is smpt.gmail.com (plus) my email address.
Rules/Add rule window, on the MacBook third line is 'Any Recipient', on the iMac third line is 'From."
The last box on that line has my email address on the MacBook.
The last box on that line has the last address I sent an emil to (last night), on the iMac.
On the last line on iMac, no box was selicted for 'to mailbox' > I choose 'inbox' because it is on the MacBook Pro.
Now I have a Rule #1 and am not sure I should have because there was no rules marked when I took the computer in.
Thank you. I relized I had done the labeling wrong when so much of my question appeared twice and no one else's did. I know how to do it now.
Thank you so much,
Arudi

Timeout of session / entity bean

Hi all
We are facing "RollbackException: The transaction has been marked for rollback (timed out)" excpetion. please help us in resolving this.
Here is problem description.
Code Description:
Step1: Action class calls Session bean
Step2:Session Bean does three things
A. Reads various value from database and write it to fileOutputStream
B. Generate a Sequence number using Sequence
C. Call create method of Entity Bean by local reference to insert the created file (in step 2A) in database as blob
As per our observation session bean takes around 20-30 sec in processing 2A and 2B.
But at 2-C, code raises following error
TariffDocumentBlob is the Entity Bean

We have tried out .....
- Making new Enity Bean
- changing timeout of session bean by changing it in properties
<session-deployment name="TariffSessionEJB" timeout="300" >
We are using Oracle 10g application Sever and Oracle 10.1 database.

Assuming you are using either 9.0.4 or 10.1.2, please note that default transaction time out is 30s and you can change that <transaction-config> element in server.xml. This is specified in millliseconds

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?
Regards,
Christian

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

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!

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)

     ... 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...
Best Of Luck

@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...
John
