Adf ejb jpa persistance problem

Hi everyone,
I`m a newbie to adf technology.
I was trying Build a Web Application with JDeveloper 11g Using EJB, JPA, and JavaServer Faces tutorial
([http://www.oracle.com/technology/obe/obe11jdev/11/ejb/ejb.html])
I have a problem when I try to run it.
It says;
javax.ejb.EJBException: EJB Exception: ; nested exception is:
Exception [EclipseLink-4002|http://forums.oracle.com/forums/] (Eclipse Persistence Services - 1.0.1 (Build 20080905)): org.eclipse.persistence.exceptions.DatabaseException

Problems with ADF when running sample EJB, JPA, JSF Tutorial

Hi,
I'm new to jDeveloper.
I've downloaded the version 11.1.1.2.0 and tried to do my first tutorials with the product.
I started with the sample 'Build Applications with EJB, JPA and JSF' and run to following problems:
- Part1: Step 10 expose the EJb as a Data Control
Here right-click FODFacadeBean.java and choose Create Data Control.
this option 'Create Data Control' does not come up at all. There is not such option
- Part 2: Step 1 Add Tag Libraries to a project
The option to select ' ADF Faces Components 11 '
does not come up either. I can not see any ADF related options...
Is there something missing from my installation, as I can not access these ADF components ?
Should I include the ADF components at some stage during the installation to be able to access these
or is this some licencing option ?
I downloaded the product yesterday from the public download site, filename jdevstudio11112install.exe

If yes, the ADF Faces Components 11 tag library would've been added by default (Check out in the list of tag libraries that are already added - before clicking on the Add button).

ADF and JPA question

I tried the example in 'Build a Web Application with JDev 10g Using EJB, JPA and JSF and it worked.
This example is based on two tables. Now I have 6 tables. Tables 1,2 and 3 are joined to populate an ADF table form and tables 1,2,4,5 and 6 are joined to populate another ADF form.
My question is: should I use JDev to generate all 6 entity EJBs or rather create two Oracle views for each of these joins and get JDev to generate EJB for each of these views?
Also, how can I customize the annotated queries generated by JDev? I would like to have all the native SQLs to be in separate XML files. Should I use XML files generated by JDev or create a new XML file? Is there an example of how to do that?

Hello,
I read somewhere JPA supports external XML native SQL queries and apparently these queries override named queries in entity annotations. Assuming this is true, would that be the preffered way (both queries, 1-2-3 join and 1-2-4-5 join have one input parameter each so the database views would have to be parametrized in that case)? And how should I access these XML based queries from inside the code?
Also, what queries are generated by JDev JPA when 6 tables are selected? Are all combinations based on foreign keys generated or just table (entity) and its directly related tables?
Thanks,
Sale

CAn EJB do persistance without hibernate?

Hai All.....
My doubt is that 'Can EJB do persistance without hibernate or any other tools'?
Can EJB do persistance alone??
Please Help

EJB 3, and JPA are just specification, not implementation. EJB 3 alone cannot do anything, it is just interfaces. Any product that implements the EJB 3 spec will support EJB SessionBeans and JPA and persistence.
Any JEE 5 server will support EJB 3 and JPA persistence (WebLogic, OC4J, Glassfish, JBoss, WebSphere, etc...). Each server uses a different product to support JPA, (Glassfish v2 uses TopLink Essentials, OC4J 11g uses TopLink, WebLogic uses Kodo, JBoss uses Hibernate, Glassfish v3 uses EclipseLink, etc.). Technically if you are using JEE 5, you don't need to worry about what JPA product you are using and can consider that EJB supports persistence, but more than likely you will need to know you JPA provider in more intimacy.
You will also need a database to persist to. Again most JEE server bundle a database, but most production applications prefer to choose their own database.
The JPA part of EJB also works outside of JEE, in this case you will need to choose one of the many JPA products.

Persistant problems with FF 27.0.1 on Windows 7/64

I seem to have a persistent problem with Firefox 27.0.1 and my MSN homepage. When I open FF, it takes me to both my Outlook Mail page and My MSN pages in two separate tabs. Outlook Mail had a problem taking my correct password, but that issue seems to have resolved itself (I did clear all cookies and caches related to the website). But My MSN is still giving me this message...
"The page you have requested cannot be found.
The web page you were attempting to view may not exist or may have moved — try checking the web address for typos."
I tried the same thing as I did with Outlook (deleted cookies and caches), but the problem persists. I disabled all plugins, and still no luck. The MSN Homepage comes up, and I'm shown as logged into My MSN, but when I click the My MSN link, I get the "The page you have requested..." message.
Another issue relating to both websites is password remembering. FF will NOT ask to remember the passwords for those sites. I have Remember Passwords box checked in Settings and it does for other sites, but not my Homepage(s). Clearing cookies/caches didn't help, and the password is not listed in the Remembered Passwords page of Settings.
Finally, Firefox on my home laptop (Windows 7/64 as well) freezes and crashes a lot, as well as displayes a warning there is something with Flash, which I have updated many times over.
I used to use Internet Explorer as a browser exclusively until I started having problems with certain websites not allowing me to log in. I realized it was not the website, but some incompatibility with IE. I started using Firefox, and fouind no problems, and heard it was more secure and easier to configure than Internet Explorer anyway. But since these problems started occurring (especially with NO way for me to log onto My MSN), I have to go back to using IE (except for select website logons), which is disappointing :-(.

About your home page; Manually set up Firefox with the window(s) and tab(s)
the way you want them to be. Then;
'''''Firefox Options > General > Homepage'''''.
Press the button labeled ''''Use Current'''.'
=====================================
Open a new window or tab. In the address bar, type '''''about:config'''''.
If a warning screen comes up, press the '''''Be Careful''''' button.
This is where Firefox finds information it needs to run.
At the top of the screen is a search bar. Enter '''''browser.newtab.url'''''
and press enter. '''''browser.newtab.url'''''
tells Firefox what to show when a new tab is opened.
If you want, right click and select '''''Modify'''''. You can change the
setting to; about:home (Firefox default home page), 
about:newtab (shows the sites most visited), 
about:blank (a blank page), 
or you can enter any web page you want. 
The same instructions are used for the new window setting, listed as
'''''browser.startup.homepage'''''.

Stored procedure, EJB, JPA, and JavaServer Faces

Hi!
I am currently working on a Web application using EJB, JPA, and JavaServer Faces. A part of the
business logic is already stored in the database as stored procedures, so we need to call those
procedures (instead of named queries) through a EJB and represent the data on the web tier.
Where can I find an extensive tutorial using this technology? There is no such tutorial in the Oracle Learning Library.
Maybe somebody can provide a link and/or example.
Thanks in advance for your help!

Hi,

JPA persist() or merge()

Hi All,
I would like to get clarification between using JPA persist() and merge() where there is a OneToMany EMPLOYEE table unidirectionally joint to ManyToOne TELEPHONE table.
The code snippet for OneToMany Employee.java entity object is as follows:
@Entity
@IdClass(EmployeePK.class)
@Table(name="EMPLOYEE", catalog="CorporationDB", schema="")
public class Employee implements Serializable {
@OneToMany(cascade={CascadeType.ALL}, fetch=FetchType.EAGER)
 @JoinTable(name="EMPLOYEE_TELEPHONE", catalog="CorporationDB", schema="",
 joinColumns={@JoinColumn(name="FIRSTNAME", referencedColumnName="FIRSTNAME"),
 @JoinColumn(name="SURNAME", referencedColumnName="SURNAME"),
 @JoinColumn(name="AGE", referencedColumnName="AGE"),
 @JoinColumn(name="SEX", referencedColumnName="SEX")},
 inverseJoinColumns={@JoinColumn(name="TELEPHONE_ID")})
 private Collection<Telephone> telephones = new ArrayList<Telephone>();
 public Collection<Telephone> getTelephones()
 return telephones;
 public void setTelephones(Collection<Telephone> telephones)
 this.telephones = telephones;
 }The corresponding detail for ManyToOne Telephone.java entity object is:
@Entity
@Table(name="TELEPHONE", catalog="CorporationDB", schema="")
public class Telephone implements Serializable {
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name="ID")
 private int id;
 @Column(name="TELEPHONE")
 private String telephone;
 public void setTelephone(String telephone) {
 this.telephone = telephone;
 public String getTelephone() {
 return telephone;
 }I would like JPA to to ignore (not overwrite) existing record and only add newer unique telephone numbers. persist() does that except it is throwing the following exceptions and continually re-trying to insert the duplicate records:
Local Exception Stack:
*Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.1 (Build b60e-fcs (12/23/2008))): oracle.toplink.essentials.exceptions.DatabaseException*
Internal Exception: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry Allan-Smith-20-M' for key 'PRIMARY'
Error Code: 1062
Call: INSERT INTO CorporationDB.EMPLOYEE (FIRSTNAME, SURNAME, AGE, SEX.....) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)
*bind => [Allan, Smith, 20, M,....]*
Query: InsertObjectQuery(finance.Employee@1d2d80c)
JTS5054: Unexpected error occurred in after completion
On the other hand, merge() ignores (does not add) duplicate Employee record (good) but it still duplicates the ManyToOne TELEPHONE table. Is it because of the OneToMany(cascade={CascadeType.ALL}} property in Employee.java which duplicates TELEPHONE records automatically? As a result, how to ensure that only unique OneToMany (EMPLOYEE) & ManyToOne (TELEPHONE) records are added once?
persist() seems to work fine except that it is continually erroring out instead of skipping to the next new record.
This Java EE 5 application is running properly.
I am running JDK1.6.0_7, GF2.1 and MySQL on Windows XP.
Thanks in advance,
Jack

I would recommend you continue to use TopLink Essentials as your JPA provider by setting your provider in your persistence.xml, or upgrading to EclipseLink and setting it as your provider. The latest WLS release also includes EclipseLink.

Adf faces command button, bindings and ejb 3.0 persisting problem

When mapping the persist method to an adf command button it got this error:
1. JBO-29000: java.lang.IllegalArgumentException: PERSIST impossible sur l'objet détaché : hr.entity.Departments@1b21.; nested exception is: java.lang.IllegalArgumentException: PERSIST impossible sur l'objet détaché : hr.entity.Departments@1b21. -

Is that because Departments are serialized by the container when the session bean is accessed by the data control to catch the data when the form is populating and entities are detached from the persisting context ? or something else ?
I bind the button to the current row data provider for the departments. Is it correct, isn't ?

EJB + JPA Troubles

hello
can anyone help me with this problem
atm i'm making a project which uses EJBs (with JPA) and some fields in the EJBs get auto generated when persisting an EJB entity to the database
Writing to the database and reading out of it works perfectly, but when i persist a brand new entity to the table, i don't receive the brand new generated ID
(ID is a primary key in the table)
is there any way to update the persisted entity right after persisting it to the database ? so that my entity, which got persisted, gets his ID injected?
this is my code for inserting a new entity into the database:

What database and JPA provider are you using? Since you are using a SEQUENCE object to generate the id, you should see it assigned after calling the persist(). Potentially you are using IDENTITY sequencing (not on Oracle), so you must first call flush() to have the id assigned.
see,

Question for Steve Muench - ADF/EJB & Applets?

Steve or anyone who can help - Do you have any sample demo that can demonstrate how to take advantage of ADF caching technology on the server, or an EJB solution integrated with an applet in a web application?
It is kind of late in the game, because we are about to roll out an application in our company, nevertheless we are still researching a better way for handling tremendous amount of data by our applet. We are using F1 Formula engine (spreadsheet like tech) in our applet. But, we have severe performance problems, especially in our remote locations trying to load thousands of rows in the applet and on top of that do all kinds of formatting and Excel like functionality in the applet grid at run time.
We are looking for a way to integrate ADF or EJB caching solution with our applet, so that we can cache the client data on the app server if possible, in order to improve performance.
Any guidance, suggestion and help is very much appreciated.
Thanks,

Hi,
my recommendation would be to use JavaWeb Start with BC deployed as EJB to the Application Server. This way you have a real client installation and don't need to download the Applet classes all the time (and JClient, assuming you use JClient, comes with a couple of libraries slowing down the initial application startup). Using EJB on the middle tier allows you to use batch mode, which reduces the number of roundtrips between the client and the server. Note that the default implementation is synchronous, which is more chatty.

Referencing EJB 3.0 ,problem

Hello I have 2 session EJB 3.0 and I would reference one on body of another , but
I have an error form embedded OC4J when I run DEBUG .
Here is my simply code
TransactionController ---
package com.savino.banking.model.facade;
import com.savino.banking.model.entity.Transaction;
import com.savino.banking.model.entity.TransactionItem;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless(name="TransactionController")
public class TransactionControllerBean implements TransactionController,
TransactionControllerLocal {
@PersistenceContext(unitName="Model")
private EntityManager em;
public TransactionControllerBean() {
public Object mergeEntity(Object entity) {
return em.merge(entity);
public Object persistEntity(Object entity) {
em.persist(entity);
return entity;
and I declare a reference to TransactionController into AdminController :
package com.savino.banking.model.facade;
import com.savino.banking.common.exception.BusinessException;

@PersistenceContext(unitName="Model")
private EntityManager em;
@EJB(name="myController",beanInterface=TransactionControllerLocal.class,beanName="TransactionControllerLocal")
TransactionControllerLocal controller;
public AdminControllerBean() {
And this is the error that I caught :

Persist problem in cascade using @OneToMany

We are trying to persist an object which has a OneToMany relationship to other objects with CascadeType.ALL
When we persist, the log shows that it creates the INSERT statement with the correct bind variables (sequence-generated REPORT_ID, etc.) for the first object.
The problem happens when it tries to cascade and insert the Many part. The log shows the it tries to create the INSERT statement for the second object but the bind variable for the REPORT_ID is null.
Since we defined the relationship of the OneToMany using the REPORT_ID, we assumed that the REPORT_ID that was auto-generated for the first object would be used for the @Many objects.
What are we missing ??????
First Object:
@Id
@SequenceGenerator(name = "REPORT_HEADER_S", initialValue = 1, allocationSize = 1)
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "REPORT_HEADER_S")
@Column(name = "REPORT_ID", nullable = false)
private Long reportId;
@OneToMany(mappedBy = "report", cascade = { CascadeType.ALL})
private List<Summary> summaryList;
Second Object
@ManyToOne
@JoinColumn(name = "REPORT_ID", referencedColumnName = "REPORT_ID")
private Report report;

Hello, Chris.
Thank you for your reply.
The structure of my tables is:
table document (id int not null constraint document_pk primary key,
table document_price (document_id int not null constraint document_price_fk references document (id),
date date not null default current_date,
price decimal(9,2) not null,
primary key (document_id, date)).
The entity classes are:
@Entity @Table(name = "DOCUMENT")
public class Document implements Serializable {
@TableGenerator(name = "document_generator", table = "ID_GENERATION", pkColumnName = "TABLE_NAME", valueColumnName = "ID_VALUE",
pkColumnValue = "DOCUMENT", allocationSize = 1)
@Id
@GeneratedValue(generator = "document_generator")
@Basic(optional = false)
@Column(name = "ID")
private Integer id;
// other fields
@OneToMany(cascade = CascadeType.ALL, mappedBy = "document", fetch = FetchType.LAZY)
private Collection<DocumentPrice> documentPriceCollection;
// constructors, getters, setters ...
@PostPersist
public void initializePrices() {
for (DocumentPrice dp : documentPriceCollection) {
dp.documentPricePK.setDocumentId(id);
@Entity
@Table(name = "DOCUMENT_PRICE")
public class DocumentPrice implements Serializable {
@EmbeddedId
protected DocumentPricePK documentPricePK;
@Basic(optional = false)
@Column(name = "PRICE")
private BigDecimal price;
@JoinColumn(name = "DOCUMENT_ID", referencedColumnName = "ID", insertable = false, updatable = false)
@ManyToOne(optional = false, fetch = FetchType.LAZY)
private Document document;
// constructors, getters, setters ...
@Embeddable
public class DocumentPricePK implements Serializable {
@Basic(optional = false)
@Column(name = "DOCUMENT_ID")
private int documentId;
@Basic(optional = false)
@Column(name = "DATE")
@Temporal(TemporalType.DATE)
private Date date;
// constructors, getters, setters ...
I create first Document entity, create DocumentPrice entity and add DocumentPrice entity to the documentPriceCollection of the first Document entity. I invoke commit method of my entity manager, and corresponding rows are added to the document and document_price tables.
I invoke clear method of my entity manager.
Then I create new entities Document and DocumentPrice and add new DocumentPrice entity to the documentPriceCollection of the new Document entity. I invoke commit method and get the following exception:
oracle.toplink.essentials.exceptions.ValidationException
Exception Description: Cannot persist detached object [entities.DocumentPrice[documentPricePK=.entities.DocumentPricePK[documentId=0;
date=Sat May 29 00:00:00 MSD 2010];
price=11]].

at oracle.toplink.essentials.internal.ejb.cmp3.base.EntityManagerImpl.persist(EntityManagerImpl.java:205)
And I see through debugging that @PostPersist method of the Document entity isn't invoked during second commit before the exception is generated.
What should I do to avoid exception during second commit?

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.
