How to use composite entities which driven by different PU via hibernate

Hi experts,
There are 2 different persistence unit in my project.
PU_A: Application entities, that can execute all crud operations.
PU_B: This one has some views which contains outside data. I can just read data from here
But i want to create foreign key in some entities which are in PU_A by using immutable-entity which managed by PU_B persistence-unit.
If you could view on following snippets. I have IncomingPaperwork entity which is driven by PU_A and ProjectView which is driven by PU_B.
After i applied this issue; When deploy the application exception that is below occured :

Not quite what I meant - I was suggesting you load the entity immediately after reading it from PU_B, or anytime before associating it into PU_A, so before the merge. What you have not shown though is any code on how you are obtaining IntegrationDepartment and integrating it into PU_A, or what you mean by it is returning a refreshed version of Topic. This problem could also be the result of how your provider works internally - this is a TopLink/EclipseLink forum post so I cannot really tell you why you get the exception other than it would be expected to work as described with EclipseLink as the JPA provider.
So the best suggestions I can come up with are prefetch your entity, try posting in a hibernate forum, or try using EclipseLink/TopLink so someone here might be better able to help you with any problems that arise.

How to access two entity managers from two different servers?

Hello
My test programm is trying to access two glassfish application servers (gf 2.1). The code base of these servers is the same, the persistence layers are just accessing different databases -> one ist the staging/test system, the other the live server.
After setting the connection and obtaining the em via the class persistence i can not fetch the em from the other system.
          properties.setProperty("org.omg.CORBA.ORBInitialHost", "host1");
          properties.setProperty("org.omg.CORBA.ORBInitialPort", "port1");
                InitialContext ctx = new InitialContext(properties);
          entityManagerFactory1 = Persistence.createEntityManagerFactory("pu/refdata");
          entityManager1 = entityManagerFactory.createEntityManager();After that Persistence seems to have been bound to host1 forever, so i can not fetch a reference to the em of host2. There is another createEntityManagerFactory method accepting a map but i dont find any reference for the properties, maybe that would help - dont know.
Regardless of what i do, any further call to Persistence.createEntityManagerFactory returns the handle of entityManagerFactory1.

I want to use the EntityManagers bound to the DataSources provided by different app servers.
Below you find an example persistence.xml with three entries. 1 & 2 have the same jta data source, 3 is different.
My point is that Persistence binds the new factory in a wrong way if the jta data source String has already been resolved.
If a progamm sets connection properties for app server 1 and fetches an entityManagerFactory for pu/refdata_Live, then sets connection properties for app server 2 with pu/refdata_Test they get different factory instances bound to the same server, in this case app server 1.
If i know set the connection properties for app server 3 with pu/refdata3 Persistence sees that the jta data source "dbc/ref3" has not yet been resolved and tries to connect to the app server 3. Which it should have done for app server 2 too.
<persistence-unit name="pu/refdata_Live" transaction-type="JTA">
     <provider>oracle.toplink.essentials.PersistenceProvider</provider>

How to track beans which are destroyed, but no exception log?

According to the WLS console, we have two out of about 30 entity beans
which have instances which are being destroyed. However, I cannot find
the exception which is causing them to be destroyed. I see nothing in
the WLS logs, nothing in our own logs, nothing, nothing, nothing.
I am wondering if this might be because for those two beans, there are
finder methods which are being invoked, and which may not find anything,
in which case the exception is caught and processing continues
appropriately. Is this a scenario where a bean instance might be created
and then destroyed?
Any ideas on how I can determine why these beans on being destroyed, if
the above scenario does not apply?
Thanks!

Well, there are only 2 paths to 'does not exist' in the spec.
unsetEntityContext or system exception. If unsetEntityContext isn't being
called, then it must be a system exception. If that isn't being logged, the
container isn't obeying the spec. If a FinderException is causing the
destruction of the instance, that isn't spec compliant, either. A
reproducible test case and a support call may be your best course of action.
Bill
"Jay Schmidgall" <no@spam> wrote in message news:41dd5bd9$1@mail...
Well, I put logging in the unsetEntityContext method and it is
apparently not being called; max-beans-in-cache is not explicity set, so
it defaults to 1000, I believe, and the console tells me the cached
beans current count is under 50 for both.
On the other hand, the scenario I suggested does seem to cooincide well
with the destroyed count; that is, after the bean is not found by the
finder, the destroyed count goes up. From your description, that seems
like it is just coincidence, but it is definitely there.
bill kemp wrote:
Finder methods are called on a pooled instance of the bean. If the
finder
doesn't find the entity, a FinderException(which is just an application
exception) should be thrown, which is reported to the client, but the
instance is not destroyed. If a system exception is thrown, thecontainer is
supposed to log it before it destroys the instance. The only other pathto
destruction in the state diagram is when the bean goes from 'pooled' to
'does not exist' when the container calls the unsetEntityContext method.So,
maybe put some output code in the unsetEntityContext method to see ifthe
container is removing beans because of cache size considerations. Just a
guess. Do you have <max-beans-in-cache> set to anything in particular?

Hi,
Just run the db_setup.sh script located in the bin directory of ias
If you just give the Oracle Home directory the libraries will be found.
Register a Datasource pointing to the service you defined in tnsnames.ora

I am trying to run a Entity bean which gives null pointer error while

the problem, but my guess is it cannot find or instantiate the object
since it cannot connect to the proper database.
Could anybody help me with it?

How to communicate between UNI ports?

Hi
I have a new ME3400 series switch with IOS (me340x-metrobase-mz.122-37.SE1), it has 24 fastethernet and 2 gig fiber uplinks
Now all the ports except fiber uplinks are uni ports by default.
So can't communicate with each other. Now i wishes to make them communicate while remaining in uni port-type.
On forums the solution is to declare them as member of community vlan.
My questions are
1) can i no shut the secondry vlan interface?
2) From which pool i have to give ip to my system either from primary vlan pool or secondry vlan pool?
3) In both cases i can't communicate with the default gateway i.e: the ip of vlan even the port is member of community vlan. so how to communicate them while being in uni ports?
The sh run of switch is below

Create two separate connection pools. Each one has its own url/userID/password to its own database. Example: If both are Oracle databases, you need the JDBC driver jar file in your classpath. You'll have to research how to create a connection pool.That is a pretty specific answer. Certainly inappropriate, for example, if the OP is attempting to just move records. Or compare records.
Probably ony useful if the OP wants to present to a client data from two databases. But since the OP said "communicate" that seems unlikely.

Help:How can I run the J2EE Client Application? Thanks

Help:How can I run the J2EE Client Application that will access the remote J2EE1.4 application server which runs on another host computer?
I have developped a stateles senterprise java bean name converter and deloyed it in the j2ee1.4 application server on the host machine A. The converterbean provides the remote home interface and remote interface. At the same time I have developped the j2ee application client named convertappclient. When I access the conveter bean at host computer A through the script 'appclient.bat' as 'appclient -client convertappclient.jar', the client can access the bean sucessfully. Now I want to access the bean through the script 'appclient.bat' at host computer B,what files should I copy from host computer A to host computer B;and what the command line should be like? Thanks!
The following are the code of the enterprise java bean and it's home interface .
The client code is also provided.
The enterprise java bean:
package converter;
import java.rmi.RemoteException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
import java.math.*;
public class ConverterBean implements SessionBean {
BigDecimal yenRate = new BigDecimal("121.6000");
BigDecimal euroRate = new BigDecimal("0.0077");
public ConverterBean() {
public BigDecimal dollarToYen(BigDecimal dollars) {
BigDecimal result = dollars.multiply(yenRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public BigDecimal yenToEuro(BigDecimal yen) {
BigDecimal result = yen.multiply(euroRate);
return result.setScale(2, BigDecimal.ROUND_UP);
public void ejbCreate() {
public void ejbRemove() {
public void ejbActivate() {
public void ejbPassivate() {
public void setSessionContext(SessionContext sc) {
The bean's remote home interface :
package converter;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface ConverterHome extends EJBHome {
Converter create() throws RemoteException, CreateException;
The bean's remote interface:
package converter;
import javax.ejb.EJBObject;
import java.rmi.RemoteException;
import java.math.*;
public interface Converter extends EJBObject {
public BigDecimal dollarToYen(BigDecimal dollars) throws RemoteException;
public BigDecimal yenToEuro(BigDecimal yen) throws RemoteException;
The j2ee application client:
import converter.Converter;
import converter.ConverterHome;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;
import java.math.BigDecimal;
public class ConverterClient {
public static void main(String[] args) {
try {
Context initial = new InitialContext();
System.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url","jnp://10.144.97.250:3700");
Context myEnv = (Context) initial.lookup("java:comp/env");
Object objref = myEnv.lookup("ejb/SimpleConverter");
ConverterHome home =
(ConverterHome) PortableRemoteObject.narrow(objref,
ConverterHome.class);
Converter currencyConverter = home.create();
BigDecimal param = new BigDecimal("100.00");
BigDecimal amount = currencyConverter.dollarToYen(param);
System.out.println(amount);
amount = currencyConverter.yenToEuro(param);
System.out.println(amount);
System.exit(0);
} catch (Exception ex) {
System.err.println("Caught an unexpected exception!");
ex.printStackTrace();
}

Surprisingly I find an upsurge in the number of posts with this same problem. I recently found a post which gave a nice link for this. Follow the steps and it should help:

Tag attempted to define a bean which already exists

I am having problems with something i thought was solved in version 10.1.3.0.0, but obviously not.
Here is the error message i get:
500 Internal Server Error
OracleJSP: oracle.jsp.parse.JspParseException: /html/portlet/journal_content/view.jsp: Line # 101, </liferay-portlet:renderURL>
Error: Tag attempted to define a bean which already exists: portletURL
I have tried adding init-param forgive_dup_dir_attr to the jsp servlet, but it doesn't help.
Any ideas how to solve this??

Help reg. read only CMP bean in the examples!!

Hi,
I have been working with examples of EJB in WLS 6.1
I used the Access database with CMP.
The basic entity beans, both CMP and BMP worked well.
However when I tried the read-only Stock Bean and write StockWriter Beans... I received the following error... I am not sure what does it say...

There was an exception while creating and using the Beans.
