I met a problem when I deploy a entity bean!
I had developed a simple entity--only have
two columns use Jbuilder 6.0 Enterprise,
when I deploy it with weblogic 6.1,I met
the following error :

Hi,
Within you weblogic-cmp-rdbms-jar.xml file you will have an entry:
<data-source-name>Oracle</data-source-name>
This links to a DataSource deployed on WebLogic which in turn links to a
connection pool to the database where you persist the entity.
So do you have a DataSource called Oracle?
Is this correctly deployed?

Met a problem when excute a process about Create InfoArea
Dear all,
we met a problem when excute a process in our bw system:
our process as follow:
rsa1(Data Warehousing Workbench:Modeling) --> InfoProvider --> Create InfoArea
the below error message window came out.
error in object editing
No valid change license available for n
/BPR3R/
Choose 'Display object' or 'Cancel'.
its detail as follow:
Message no. TO127
Diagnosis
You cannot edit the object AREA 0INDUSTRIES. This may be due to the following reasons:
The corresponding namespace /BPR3R/ is not entered in the namespace table with a valid change license.
In the namespace table there is no entry with a valid change license that matches the template /BPR3R/.
System Response
The function terminates.
Procedure
Check the name of the object AREA 0INDUSTRIES. If necessary, choose another object name.
Otherwise, let the system administrator check the change licenses of the namespaces in your SAP system.
Maintain the namespaces in the Tools of the Transport Organizer under Administration -> Display/Change Namespaces.
You need to check and correct the entries that match the template /BPR3R/.
You need to distinguish between the following cases:
The namespace is /0SAP/:
Make sure that the namespace role is C (recipient) and the flags SSCR popup and SAP standard are activated. The license fields remain empty.
You did not create the namespace yourself. Instead, the namespace owner is SAP or another software vendor.
Make sure that the namespace role is C (recipient). The field Repair license must either contain the valid license, or the flag SSCR popup must be activated. Contact the namespace owner and ask what you should now do, and what the valid repair license is.
You are the namespace owner:
Proceed according to the documentation on applying for and setting up namespaces. If the namespace role is P (producer) then you need a valid development license. For information on this, see the SAP Library under BC - Basis Components -> Change and Transport System -> BC - Namespaces and Naming Conventions -> Reservation of Namespaces).
Please give your advice.
RegardsHi,
this forum is about the SAP BusinessObjects BI Solution architecture. I would suggest you post your question into the SAP BW Forum.

I think you are trying to test the Hello world EJB example shipped with the product. As a first
step I would recomend you to go through every line of the document on deploying this application,
since, I too have experienced many errors while trying to deploy the sample applications, but on
following the documentation, I subsequently overcame all the errors and have been working with the
applications. So please follow the steps in documentation and let me know, if you still encounter any
issues.

Deployment problem sdk 1.4 with entity bean
hallo!
i have a big problem with the j2ee sdk 1.4. when i want to add an entity bean to my ear-file, everything goes good, but when i put the sql-ql for the finder-method and save the file i got an error like this
xxxxxxx.ear is corrupt or cannot be read
when i dont save and will show the descriptor it generates an empty descriptor for this entity bean.
the problem is, that the deployment tool cannot generate the deployment desciptor for entity beans. with session bean there was no problems.
hope somebody can help me.
thanksThere's bug in non-U.S. locales. The workaround is described in this thread:

Problem deploying EJB entity bean
Hi all!
I'm trying to deploy an CMP entity bean with composite primary key.
My environment is Oracle 8i (8.1.7) on W2K Professional and I'm using JDK 1.3.1_02.
The error I get is:
Compiling Stubs...done
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: null
I don't understand what am I doing wrong...
Any help will be highly appreciated.

Thanks in advance.Hi Nikos,
I obviously don't know what your entire situation is, but you may not
be aware that Oracle's DBMS embedded EJB container does not work well,
and as a result, Oracle decided to replace it with an external EJB
container which is part of a product called "Oracle Containers for
J2EE" (otherwise known as "OC4J"). The "other" forum (the J2EE forum)
deals mainly with OC4J.
As far as I know, Oracle recommends doing your EJB related work with
OC4J and not with the embedded EJB container.
Good Luck,
Avi. That's correct
Java code, implementing data bound logic, can still run in the database as Java stored procedures/packages/functions/triggers
while J2EE componentsdeployed in middle-tier implement business logic. Java in database enable the database to be an active participant to your deployment platform
in 9iDB R2 you will even be able to call-out Web client (using HTTP Client), EJB client (using oc4jclient.jar) or Web Service client
(using SOAP libraries)

Deploying BMP Entity Bean with primary key calss
Hi,
I am using EJB 2.0 with and websphere studio 5.0 and database is sql server 2000.
My BMP Entity bean has a primary key class.From my client I am invoking the Entity Bean by calling it's findbyprimarykey method.
The home interface of my findbyprimarykey method returns a class of type Remote.But in the Entity Bean class,the return type is the primarykey class type.
My problem is invoking this findbyprimarykey from the client to get the remote interface so that the other business methods of the entity bean can be called.
The control goes into the ejbFindbyPrimaryKey but when it is returing from the Entity Bean class,it gives a remote exception (as the return type in Entity Bean class and Home interface are different for the findbyprimarykey method).
I think that somewhere in the deployment decriptor in my websphere,i have to specify the primarykey class type,which i am missing out and hence getting the error.
Please help me out with your advice and solution.
Thanks

How to specify JDBC Oracle url using deployment tool - Entity Bean
Hello I'am new to EJB.
When creating a entity bean-managed persistence and you need to specify the jdbc url with user name
and password to establish a connection object, how does one specify that in the deployment
tool?
Heres an example of what has in the J2EE tutorial has in AccountEJB to get an connection object
private String dbName = "java:comp/env/jdbc/AccountDB";
private void makeConnection() throws NamingException, SQLException {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup(dbName);
con = ds.getConnection();
Now if my oracle jdbc url is to be jdbc:oracle:thin:@Abe:1521:dev
ie My host is Abe, port number 1521 and database name of dev and username/password will be system/manager.
what would my dbName be at the top?
Would my JNDI lookup of a DataSource resource "java:comp/env/jdbc/AccountDB" become "java:comp/env/jdbc/dev" for starters?
In the Resource Factories Reference Code I've add a reference of
Coded Name: jdbc/dev
Type: javax.sql.DataSource
Authentication: Container
and down the bottom of the I've put JNDI Name: MyAccount
according to the AccountClient code of:
Context initial = new InitialContext();
Object objref = initial.lookup("MyAccount");
and put User Name of "system" and Password of "manager"
I'am sure in the source code I have to put
Class.forName("oracle.jdbc.driver.OracleDriver")
else you would get that no sutitable driver error, maybe you don't have to if ejb server is smart enough?
What I'am confuse about is where to specify the jdbc url of "jdbc:oracle:thin:@Abe:1521:dev" ??
Know it won't work because of this vital part. Do you have to put that somewhere else in the deployment tool or properties file, or some other tool??
Please help
Thanks
Abraham KhalilWhen running the client after successful deployment with jdbc, I'am getting

One thing I don't like about EJB is that everything is transparent which is good! But its much
harder to debug! :( Tried to see if I can figure it out. Hope someone has seen this problem before? -
Can I deploy the entity bean in different jar files?
I have an application EAR, which contains several JARs. I have an entity bean A that has relationships with 2 other different entity beans B and C in the same DB. Now, I have to deploy this entity A together with B in AB.jar, and A with C in AC.jar. Both AB.jar and AC.jar are modules of the same application EAR file. They all use the same data sources to the same database, and named by different <ejb-name>.
I have no problem with deploying the app to WebLogic 8.1. But the JSP page accessing entity A got errors. Sometime, it got error complaining that the container-generated ejbFindAccount mehtod is abstract.
My questions are,
Can an entity bean be defined twice in 2 different jars?
When container load AB.jar and AC.jar, does it generate the finder methods twice?
I guess there are some name conflicts going on here. What should I do to avoid it?
Any comments are very much appreciated.Thanks for your answer, but how can I use it in connection with relationships?

Noob Question: Problem with Persistence in First Entity Bean
Hey folks,
I have started with EJB3 just recently. After reading several books on the topic I finally started programming myself. I wanted to develop a little application for getting a feeling of the technology. So what I did is to create a AppClient, which calls a Stateless Session Bean. This Stateless Bean then adds an Entity to the Database. For doing this I use Netbeans 6.5 and the integrated glassfish. The problem I am facing is, that the mapping somehow doesnt work, but I have no clue why it doesn't work. I just get an EJBException.
I would be very thankfull if you guys could help me out of this. And don't forget this is my first ejb project - i might need a very detailed answer ... I know - noobs can be a real ....
So here is the code of the application. I have a few methods to do some extra work there, you can ignore them, there are of no use at the moment. All that is really implemented is testConnection() and testAddCompany(). The testconnection() Methode works pretty fine, but when it comes to the testAddCompany I get into problems.
Edit:As I found out just now, there is the possibility of Netbeans to add a Facade pattern to an Entity bean. If I use this, everythings fine and it works out to be perfect, however I am still curious, why the approach without the given classes by netbeans it doesn't work.
public class Main {
private EntryRemote entryPoint = null;
public static void main(String[] args) throws NamingException {
Main main = new Main();
main.runApplication();
private void runApplication()throws NamingException{
this.getContext();
this.testConnection();
this.testAddCompany();
this.testAddShipmentAddress(1);
this.testAddBillingAddress(1);
this.testAddEmployee(1);
this.addBankAccount(1);
private void getContext() throws NamingException{
InitialContext ctx = new InitialContext();
this.entryPoint = (EntryRemote) ctx.lookup("Entry#ejb.EntryRemote");
private void testConnection()
System.err.println("Can Bean Entry be reached: " + entryPoint.isAlive());
private void testAddCompany(){
Company company = new Company();
company.setName("JavaFreaks");
entryPoint.addCompany(company);
System.err.println("JavaFreaks has been placed in the db");
}Here is the Stateless Session Bean. I added the PersistenceContext, and its also mapped in the persistence.xml file, however here the trouble starts.
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
@Stateless(mappedName="Entry")
public class EntryBean implements EntryRemote {
@PersistenceContext(unitName="PersistenceUnit") private EntityManager manager;
public boolean isAlive() {
return true;
public boolean addCompany(Company company) {
manager.persist(company);
return true;
public boolean addShipmentAddress(long companyId) {
return false;
public boolean addBillingAddress(long companyId) {
return false;
public boolean addEmployee(long companyId) {
return false;
public boolean addBankAccount(long companyId) {
return false;
}That you guys and gals will have a complete overview of whats really going on, here is the Entity as well.
package ejb;
import java.io.Serializable;
import javax.persistence.*;
@Entity
@Table(name="COMPANY")
public class Company implements Serializable {

public Long getId() {
return id;
public void setId(Long id) {
this.id = id;
public String getName() {
return name;
public void setName(String name) {
this.name = name;
System.err.println("SUCCESS: CompanyName SET");
@Override
public int hashCode() {
int hash = 0;
hash += (id != null ? id.hashCode() : 0);
return hash;
@Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Company)) {
return false;
Company other = (Company) object;

return false;
return true;
@Override

return "ejb.Company[id=" + id + "]";
}And the persistence.xml file

Best regards and happy coding
Taggert
Edited by: Taggert_77 on Jun 8, 2009 2:27 PMWell I don't understand this. If Netbeans created a Stateless Session Bean as a facade then it works -and it is implemented as a CMP, not as a BMP as you suggested.
I defenitely will try you suggestion, just for curiosity and to learn the technology, however I dont have see why BMP will work and CMP won't.
I also don't see why a stateless bean can not be a CMP. As far as I read it should not matter. Also on the link you sent me, I can't see anything related to that.
Maybe you can help me answering these questions.
I hope the above lines don't sound harsh. I really appreciate your input.
Best regards

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! -
Deploying CMP entity bean throws compilation error.
Jdeveloper build works fine but the server deployment ( embedded) fails. I linked tools.jar to j2ee home dir, same version as jdev uses. Session beans deploy OK.
The table corr to the entity bean has a primary key and the entity bean was created by dragging-dropping table onto UML diagram.
error is >>>cmp-field of type 'java.lang.Long' does not have a no-arg constructor which is needed for properties/fields based mapping<<<, message details follow after dashed line.

Error Deploying CMP Entity Bean
Hi,
I am new to Entity Beans and am trying to deploy a CMP Entity Bean without any success.
I did search this forum for similar issues and tried those suggestions as well but that has not helped. Was wondering if someone could help me out on this.
The Entity bean has 2 fields: name and description.
The ejb-jar.xml file for this bean is:
<enterprise-beans>
<entity>
<ejb-name>Product</ejb-name>
<home>example.cmp.ProductHome</home>
<remote>example.cmp.Product</remote>
<ejb-class>example.cmp.ProductBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.String</prim-key-class>
<reentrant>false</reentrant>
<cmp-version>2.x</cmp-version>
<abstract-schema-name>PRODUCTS</abstract-schema-name>
<cmp-field>
<field-name>name</field-name>
</cmp-field>
<cmp-field>
<field-name>description</field-name>
</cmp-field>
<primkey-field>name</primkey-field>
<query>
</query>
</entity>
</enterprise-beans>
The error that I get while deploying the bean is:
