Persistence outside EJB
Hi
I am developing a web app with tomcat and JSF and apache derby db. I want to use the java persistence api to talk to the DB. (Note: I am not using the EJBs here)
I would like to know if this possible or should I just go with hibernate. This application will reside in an embedded device with good processing power.
So please also suggest adding java persistence or hibernate would be a big overhead compared to the plain JDBC access. If so how much would be the overhead
thanks
Absolutely. The Java Persistence API was designed to be usable from outside the EJB tier.
You can use it from within other Java EE tiers such as the web tier or Application Client tier,
or outside of a Java EE environment altogether.
The Java Persistence API was developed as part of the EJB 3.0 JSR but in future releases
it will be evolved as its own specification.
You can find some more information here :

EJB Persistence problem [Data modified outside EJB]
Hello,
There is an EJB in the system which corresponds to a db table, say it "AppBean", and a corresponding session bean AppSession which provides insert/remove/query service. There is another program, a webapp which might runs on another server, also makes modifications to that table.
But the EJB seems to be totally unaware of data changes made by others ... Is there a simple mechanism that would allow notification to the EJB to ask it to reload data from DB? JMS or MDB seems to be too complicated ...
Thanks in advance.
laymanHello,
Thanks for your reply first.
Do you mean that the webapp shall call the EJB's
ejbLoad method in remote interface? or is there anyway
to set a "validation" flag, as we do to Session State?Well, I actually mean that shall the webapp call the EJB's ejbLoad through it's local interface(ejb-local-ref in web.xml)? Isn't there some more elegant way to achieve this? A Java guru told me that JMS might be an "easy" way, but I know almost nothing about that.
tHANK YOU.

Dependent Object persistence in EJB 1.1
Please take a look at the following container-managed entity EJB
code:
//REMOTE INTERFACE //----------------------
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
public interface Product extends EJBObject {
public void setPrice(double price) throws RemoteException;
public double getPrice() throws RemoteException;
public String getDescription() throws RemoteException;
public void setDescription(String desc) throws RemoteException;
public ItemView getItemView() throws RemoteException;
public void setItemView(ItemView i) throws RemoteException;
//HOME INTERFACE //------------------------------
import java.util.Collection;
import java.rmi.RemoteException;
import javax.ejb.*;
public interface ProductHome extends EJBHome {
public Product create(String productId, String description,
double balance, ItemView itemView) throws RemoteException,
CreateException;
public Product findByPrimaryKey(String productId)
throws FinderException, RemoteException;
public Collection findByDescription(String description)
throws FinderException, RemoteException;
public Collection findInRange(double low, double high)
throws FinderException, RemoteException;
//EJBean //----------------------------------------------
import java.util.*;
import javax.ejb.*;
public class ProductBean implements EntityBean {
public String productId;
public String description;
public double price;
//custom java class: Item
public Item item;
private EntityContext context;
public void setPrice(double price) {
this.price = price;
public double getPrice() {
return price;
//instead of returning field Item, an object of ItemView with Item
data is returned.
public ItemView getItemView()
return new ItemView(item.getDesc(), item.getCodeNum());
public void setItemView(ItemView itemView)
this.item = new Item(itemView.getDView(), itemView.getCView
public String getDescription() { return description; }
public void setDescription(String descri) {description = descri;}
public String ejbCreate(String productId, String description,
double price, ItemView itemView) throws CreateException {
if (productId == null) {
throw new CreateException("The productId is required.");
this.productId = productId;
this.description = description;
this.price = price;
item = new Item(itemView.getDView(), itemView.getCView());
return null;
public void setEntityContext(EntityContext context) {
this.context = context;
public void ejbActivate() {
productId = (String)context.getPrimaryKey();
public void ejbPassivate() {
productId = null;
description = null;
public void ejbRemove() { }
public void ejbLoad() { }
public void ejbStore() { }
public void unsetEntityContext() { }
public void ejbPostCreate(String productId, String description,
double balance, ItemView itemView) { System.out.println
("ProductBean ejbPostCreate"); }
} // End of ProductBean
//Item //-------------
public class Item implements java.io.Serializable {
public String desc;
public int codeNum;
public Item(String desc, int CodeNum) {
desc = desc;
codeNum = codeNum;
public void setDesc(String decs) {desc = desc;}
public void setCodeNum(int i) {codeNum = codeNum;}
public String getDesc() {return desc;}
public int getCodeNum(){return codeNum;}
} //End of Item
//ItemView //-------------------------------------
public class ItemView implements java.io.Serializable {
public String dView;
public int cView;
public ItemView(String s, int i) {
dView = s;
cView = i;
public void setDView(String s) {dView = s;}
public String getDView() {return dView; }
public void setCView(int i) {cView = i;}
public int getCView() {return cView;}
Upon running the following client:
//ProductClient //-------------------------------------
import java.util.*;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
public class ProductClient {
public static void main(String[] args) {
try {
Context initial = new InitialContext();
Object objref = initial.lookup("MyProduct123");
ProductHome home =
(ProductHome)PortableRemoteObject.narrow(objref,
ProductHome.class);
Product duke = home.create("1006", "Siamese atty", 23.13,
new ItemView("Hot",12));
System.out.println("Description: " + duke.getDescription());
System.out.println("Price: "+ duke.getPrice());
System.out.println("Item desc: " + duke.getItemView
().getDView());
System.out.println("Item CodeNum: " + duke.getItemView
().getCView());
} catch (Exception ex) {
System.err.println("Caught an exception." );
ex.printStackTrace();
This is expected to create a ProductBean whose Item field variable
object will have "Hot" and 12 as its values. However, the program
output is:
Description: Ceramic Catty
Price: 19.23
Item desc: null
Item CodeNum: 0
1. I am unable to understand why the Item object contained in the
ProductBean remains null.
2. I read in a sdmagazine article, that helper objects (dependent
objects) should not be exposed directly to the client. I have used
the ItemView in line with this argument although I am not clear if
this is a requirement , if so, what is the rationale behind it.
Please see
http://www.sdmagazine.com/documents/s=739/sdm0010j/0010j.htm.
3. If I do not use ItemView and expose the Item field directly to the
client, there is a runtime error NullPointerExc eption...
4. Does EJB 2.0 adopts the same approach i.e. can depenmdent objects
be directly exposed to the client or not. Or this is just a
recommendation not a requirement?
In the above mentioned article :
(http://www.sdmagazine.com/documents/s=739/sdm0010j/0010j.htm)
"EJB enables me to improve the design I presented in Figure 1. The
problem is the address attribute; it's an object and not a primitive
value. Because I need to persist addresses, I have two options: I can
implement it as a dependent value object or as a dependent object. A
dependent value object is one that is serializable, the properties of
which are saved as a single value; it's the relational database
equivalent of a binary large object (blob). On the other hand, the
properties of dependent objects are saved as individual values, one
for each property. This appears to be a significant advantage, but it
comes at a price: A dependent object must never be directly exposed
to the clients of entity beans via its remote interface because the
persistence container is free to optimize the delivery of dependent
objects and may never fully materialize them as full-fledged classes.
What you should do, as Figure 2 indicates, is expose a representation
of the dependent object if required. I have done this with the new
versions of the getAddress() and setAddress() operations in the
Customer class that now work with instances of XmlDocument instead of
Address. A little clunky, but reasonably easy to live with in
practice. Note that I didn't have to introduce any code to maintain
the relationship between the two classes to my model."
5. This is totally new to me. I don't know what the author means when
he says 'the properties of
which (dependent object) are saved as individual values, one for each
property.' Does this mean,
the dependent object can be persisted in a separate table. How is it
possible while using CMP? 6.
And 'all this comes at a price...' I can't see what's the price.
Any help is highly appreciated.

HasanDid you forget adding "this." in the item.java.

SAS9.1 Persistence and EJB lookups (not registered in JNDI?)
I am trying to deploy a very basic EJB3 module to test my learning. The module deploys via the Admin Console without apparnet error. Unfortunately, when using the generated test page for the web-service, I am having total failure which seems to be around the persistence unit and EJBs not being created in the JNDI.
I have an @Stateless/@WebService bean:
package com.flexit.buslogic;
import java.util.logging.Level;
import javax.ejb.Stateless;
import javax.ejb.EJB;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import com.flexit.persistence.eao.OwnerFacade;
@WebService
@Stateless
public class CreateOwner {
@EJB
private OwnerFacade ownerFacade;
public CreateOwner(){}
@WebMethod
public Integer addOwner (
@WebParam(name="Name") String name){
LogUtil.log("Add owner request " +
"received for "+name,
Level.INFO, null);
return ownerFacade.findAll().size();
}The OwnerFacade EJB injection fails with avax.ejb.EJBException: nested exception is: javax.ejb.CreateException: Could not create stateless EJBIf I instantiate a 'normal' reference to OwnerFacade (ie OwnerFacade ownerFacade = new OwnerFacade(); I get a similar error in the OwnerFacade EJB in relation to an attempt to inject an EntityManager:
package com.flexit.persistence.eao;
import java.util.List;
import java.util.logging.Level;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import com.flexit.persistence.LogUtil;
import com.flexit.persistence.Owner;
@Stateless
public class OwnerFacade implements OwnerFacadeLocal, OwnerFacadeRemote {
// fields
@PersistenceContext(unitName="FlexIBuildPU")
private EntityManager entityManager;
public OwnerFacade () {
if (entityManager == null) {
LogUtil.log("unable to get an Entity Manager Instance", Level.SEVERE, null);
...The constructor logs that the entityManager is, indeed, null.
I have tried the code on SAS9 and 9.1 and using the default JavaDB and a MySQL connection pool (successful ping) and datasource (named 'jdbc/FlexDBDS') created through the Admin Console. The persistence unit is defined in a persistence.xml file in the META-INF folder:
<?xml version="1.0" encoding="UTF-8"?>

</persistence>Can anyone please save me from tearing my hair out (more)?Have managed to resolve. There were two problems
First I was attempting to access a session bean directly rather than via an interface (eejit!) - ie:
@EJB OwnerFacade ownerFacadewhen it should have been:
@EJB OwnerFacadeLocal ownerFacadeSecond, the persistence unit wasn't created properly. In playing around with persistence.xml I moved from:

Hi,
I am using java persistence api(over oracle toplinks)
I have an entity customer and another entity contacts.
customer is mapped with contact as one to many.
the contact have a field primarycontact.
I want to get the contact name from contacts for a customer where primarycontact field is true. and set this contact name as a field customercontact which is a string in customer..
I got a way by executing multiple queries.
but is it possible to do this in single query using ejb ql?
Any help will be greatly appreciated..
Thanks in advance....@Id
@GeneratedValue( @GeneratedValue(strategy= GenerationType.TABLE, generator="SOMENAME")
public int setId() {
returrn this.id;
in the database you need to create table using following commands
CREATE TABLE SEQUENCE
SEQ_NAME VARCHAR(50),
SEQ_COUNT DECIMAL(15)
and insert a row initally with the same "SOMENAME" like
insert into sequence values ( "SOMENAME", 1);
you can get the next id by adding 50(default) to "SELECT SEQ_COUNT FROM SEQUENCE WHERE SEQ_NAME = "SOMENAME"
hope this provides a solution. -
Bean-managed persistence (BMP) in EJB 3.0
I've been on the google for a few days now and haven't found one single notion on bean-managed persistence in EJB 3.0 specification. Even the official specification PDFs don't mention it :(
Help! I need BMP! Does anybody know what's the situtation in EJB 3.0? Can I and how mark an entity bean to be bean-managed persistent and use ejbLoad and ejbStore functions like in the EJB 2.0 or something like that?
Tnx in advance,
IgorTnx Frank, I was afraid of that :(
I think that is a step back for the EJB technology. Now it is fixed to the table structure, every change in the database calls for a re-desing, re-compilation and re-deplyoment.
With BMP in EJB 2.1 one was able to build a bean that modifies itself according to the table structure dinamically. Is there any way to do it in EJB 3.0?

Error while running ejbc. Fatal error from EJB Compiler ---- Error while pr
Hi!
I was deploying a test application for a session bean with sun 1 studio 5 and I started getting this message while deploying.
I had tested the bean previously and I had no problems.
I found this in the sun app server 7 release notes, but I don't understand what I'm supposed to do...
"Deployment of CMP beans fails.
The following error is thrown because there are no <query-params> entries in the container-managed persistence (CMP) bean in sun-ejb-jar.xml file:

Solution
Even if it isn't necessary for the CMP beans, add the query-params tag for finders in the sun-ejb-jar.xml file with the empty parameters."

Please go to the above docs and look thru the examples given in it.
Example 2
This query returns all products in a specified price range. It defines two query parameters which are the lower and upper bound for the price: double low, double high. The filter compares the query parameters with the price field:
"low < price && price < high"
The finder element of the sun-ejb-jar.xml file would look like this:
<finder>
<method-name>findInRange</method-name>
<query-params>double low, double high</query-params>
<query-filter>low < price && price <
high</query-filter
</finder>
I hope this hepls. In your case u just have to make it null. -
Confuse about the injecting entity in EJB 3.0?
Hi all,
I have an customersBean which is inherit from customersRemote and my problem is i' am little confuse about injecting the entity(customer).
Where can you apply the EntityManagerFactory is it outside on EJB or Inside the EJB? means outside EJB is use the web application or java application. i have and example.
this is inside on EJB...............
public class CustomersBean implements com.savingsaccount.session.CustomersRemote {
@PersistenceContext(unitName="SavingAccounts")
EntityManagerFactory emf;
EntityManager em;
/** Creates a new instance of CustomersBean */
public CustomersBean() {
public void create(int id, String name, String address, String telno, String mobileno)
try{

Customer _customer = new Customer();
_customer.setId(id);
_customer.setName(name.toString());
_customer.setAddress(address.toString());
_customer.setTelno(telno.toString());
_customer.setMobileno(mobileno.toString());
em = emf.createEntityManager();
em.persist(_customer);

package pl.jaceklaskowski.jsf.tomahawk;

List resultList = em.createQuery("SELECT p FROM Pracownik p ORDER BY p.lastName").getResultList();;
pracownicy.setWrappedData(resultList);
return pracownicy;
}When I run it on GF v2b36 I'm getting the following exception:

Does anyone have any idea what might be wrong?

http://www.jaceklaskowski.plHi Jacek,
The attribute you should set is unitName(), not name(). name() defines the location of the
@PersistenceContext dependency within the component environment (java:comp/env). It
is independent of the dependency type and appears on all Java EE environment annotations :
@EJB, @Resource, etc.
unitName() specifies the name of the associated persistence unit. If there is only one defined it's
not needed. However, in your case there are two so since it's not specified there isn't enough
information to resolve the correct one.

The key is auto_increment and is an integer.
I'm usin MySQL and it is already set up as ANSI. (running as mysqld --ansi)
Any Idea?
Thanks in advanceWhat happend when two concourrent user try to get the same key on the table? If for example I have 30 users at same time do I have lock table?
Any way here the finest log using sunone 8. The error is the same, so I think I missing something:

ejb-local-ref where to put this tag in ejb-jar.xml ??
I have an ejb-jar.xml that looks like this. I have had no problem with remote interfaces. Now I want the bean to have a local interface too.
Just let me know where the tag I have mentioned for the <ejb-local-ref> has to be put into.
When I compile this file it throws me an error which i have shown below the output of the ejb-jar.xml file

at com.sun.enterprise.management.deploy.DeployThread.run(DeployThread.java:210)Hi thanks, I'm using the default table generator offerred by the app server. my entity classes have relationship with each other. for example, in the Bid entity, I have the mapping to AuctionItem antity.
@JoinColumn(name = "auctionItems_itemid", referencedColumnName = "itemid")
@ManyToOne
public entities.AuctionItem getAuctionItems() {
return auctionItems;
public void setAuctionItems(entities.AuctionItem auctionItems) {
this.auctionItems = auctionItems;

I've been on the google for a few days now and haven't found one single notion on bean-managed persistence in EJB 3.0 specification. Even the official specification PDFs don't mention it :(
Help! I need BMP! Does anybody know what's the situtation in EJB 3.0? Can I and how mark an entity bean to be bean-managed persistent and use ejbLoad and ejbStore functions like in the EJB 2.0 or something like that?
Tnx in advance,
IgorHi Sumit,
The direction the spec took was to define a completely new persistence model rather than try to retrofit the old BMP/CMP model. As with all Java EE releases, all requirements supported in previous releases of the platform continue to be supported. That's why you can continue to choose to develop using BMP if you'd like.
However, there is no architected relationship between the Java Persistence API and BMP/CMP. One thing the Java Persistence API and CMP have in common is the belief that all database interaction code should be perfomed by the system layer and not reside in the application.
That's why you don't see BMP-like features within the new Persistence API. In addition, Entity classes developed using the Java Persistence API are not EJB components. The Java Persistence API can be used from any Java EE component (EJB, web component, Application Client) and from J2SE.
The Java Persistence API does define many lifecycle callbacks events (e.g. @PrePersist, @PreUpdate, etc.) that can be delivered to the Entity class. However, these are intended for performing tasks other than direct interaction with the persistent store.

Cookie.setPath Inconsistent with RFC 2109
My reading indicates that Java EE imposes an additional restriction beyond that in RFC 2109 on setting Cookies. That does not make policy sense. Am I interpreting the specification correctly? If so, should the Java EE part be changed? From Java EE 5
