hi JavaCrazyLover
u got why u getting the error i ma getting similar error its running fine in 8.1 but in web9.1 it is giving errors in some jsp pages may be due to versions or name spacing ie we write in top of the page DTD schema am not sure but i think , there is no jars to add on as such web 9.1 is upgraded one and it supports all files some where there will be conflicts between versions example JDK 1.5and 1.4 enum is a keyword in 9.1 but in normal in 8.1 if u get the solution for this error please mail me to [email protected]

Jdeveloper 11 and/or toplink-jpa problem

Hello,
We have a big problem with toplink-jpa or jdev 11. I tried something very similar to the jdev/jpa tutorial (http://download-uk.oracle.com/otn_hosted_doc/jdeveloper/11/demos/JPA/JPA_Demo.html), only adapted to our db. I've been trying to solve this for hours, but whenever we run the sample facade client we created, we get this as only output:
Error opening zip file: toplink/jlib/essentials-agent.jar
Error occurred during initialization of VM
agent library failed to init: instrument
Process exited with exit code 1.
I would greatly appreciate some support, I'm desesperate, this project being an experiment to see how we can evolve from "classic" toplink to toplink/jpa.

Please also note: I tried this with jre 1.5.0.6 and 1.6.0.1 . The first one says "Error opening zip file: toplink/jlib/essentials-agent.jar", 1.6 says "Error opening zip file or JAR manifest missing : toplink/jlib/essentials-agent.jar".
I also tried the 1.5.0.6 jvm which comes with jdev 10.x, which doesn't say (or does) anything.
I downloaded the las version of toplink/jpa, without any change.
All help greatly appreciated :-/

Toplink JPA Problem

Please i have this problem wth toplink in netbeans 6.1
The reason am bringin this here is that it uses toplink implementation of JPA
I have two projects
1.project A
2. Project b
In project A i have a database with Users,Contacts tables with a datasource configured as projectAdDS pointing to projectADb
In projectB i have a different database with Users,Contacts tables with a datasource configured as projectBdDS pointing to projectBDb
Now the generated Entity Classes for each projects is Users , Contacts. They have the same name but different package name
in project a the Users Entity classes is com.projectA.Users while in projectB is com.projectB.Users.
Now the problem is where the webapplication of projectA tries to save a Users it save it in projectB database.
That is the problem even when the two persistent are pointing to two different datasources.
Project A Persistent. XML

Yes,
It looks like you are getting 2 connection attempts for phonebookdb (2 is normal) but receive soapphonebook as the connection - this is odd.
But, I am working fine. In my application which is working now with <exclude-unlisted-classes>true</exclude-unlisted-classes> on "all" persistence units
I am working with two (Cell) entities in different packages (both are in the EJB jar). So this is either an issue with entities in the WAR or it is a db platform issue surrounding JavaDB
See a screencap of both persistence units working on two different datasources with the same entity "alias" but different packages
[http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebLogic_Web_Tutorial#Two_Persistence_Units]
For reference I get the same 4 logs when I attempt a single JTA connection but in my case my datasource name is listed as null even though my app continues on ok.
In the case of using both persistence units I get 2 sets of 4 logs = 8 for the 4 connections to the 2 datasources
The two datasources in my case are Oracle11g (remoteJTA) and Oracle10g (localJTA) - both using the same 11g driver - so it is easier to tell them apart in the logs.

I also do not see anything from the persistence unit "SoapProPU" in the logs from your servlet. Have you initialized both persistence units there or are there logs from the other servlet?
For example I used the following servlet with 2 references to session beans that in turn reference the 2 pu's - or you could just use persistence unit injection on the servlet.
public class FrontController extends HttpServlet implements Servlet {
@EJB(beanName="ApplicationService")
public ApplicationServiceLocal applicationService;
@EJB(beanName="ApplicationService2")
public ApplicationServiceLocal2 applicationService2;
@Local @Stateless
public class ApplicationService2 implements ApplicationServiceLocal2 {
@PersistenceContext(unitName="exampleDuplicate", type=PersistenceContextType.TRANSACTION)
private EntityManager entityManager;
@Local@Stateless
public class ApplicationService implements ApplicationServiceLocal {
@PersistenceContext(unitName="example", type=PersistenceContextType.TRANSACTION)
private EntityManager entityManager;
This may be DB platform specific, I think a reproduction on the same JavaDBPlatform is required on our side.
You may be right about the alias name that is narrowed to Userdetails (with no qualifying package). I see the same message when creating the EntityManagerFactory for the particular PU from....
m_entityName = Helper.getShortClassName(getJavaClassName());
getLogger().logConfigMessage(MetadataLogger.ALIAS, getDescriptor(), m_entityName);
and get further because I forgot to add the following exclude so that predeploy does not pick up classes from the persistence.xml classpath.
<exclude-unlisted-classes>true</exclude-unlisted-classes>
I wil let you know when I have switched my reproduction to use JavaDB.
thank you

Using Stored Procedures with TopLink / JPA : Success explanation

For those who have to use Stored Procedures in TopLink this is my success history :
To call an Stored Procedure from the persistence, we have to use the direct JDBC connection because my TopLink version ( Essentials 10g ) ? to date ( 10g ) does not have support for Stored Procedures.
Here is my code :
<address>{color:#0000ff} EntityManagerFactory JPAemfactory = null;{color}</address>
<address>{color:#0000ff} JPAemfactory = Persistence.createEntityManagerFactory ("MyPersistenceUnit"); // this is the name of the persistence unit wrote in the persistence.xml file{color}</address>
<address>{color:#0000ff} EntityManagerr MyEntityManager = JPAemfactory.createEntityManager ();{color}</address>
bq. <address>{color:#0000ff}// creation of the stored procedure calling string .... one question mark for every param, output included \\ String sql = "{call SP_GETLISTATARIFAS(?,?,?,?,?)}"; \\ // We get the JDBC connection \\ oracle.toplink.essentials.internal.ejb.cmp3.EntityManagerImpl entityManager = (oracle.toplink.essentials.internal.ejb.cmp3.EntityManagerImpl) MyEntityManager; \\ UnitOfWorkImpl uow = (UnitOfWorkImpl)entityManager.getUnitOfWork(); \\ // we create a request to the unitofwork because if dont the connection will not exist \\ uow.beginEarlyTransaction(); \\ Connection conexion = ((UnitOfWorkImpl)uow).getAccessor().getConnection(); \\ {color}{color:#0000ff} \\ try { \\ // Creation of the call and we will identify the params as they are in the stored procedure definitiondefinidos \\ CallableStatement call = conexion.prepareCall(sql); \\ {color}</address>

Hope this helps all the people that have searched a lot like me.......

I have my entity manager setup in a singleton.
I'm finding it's costly to generate the emf, but if I don't close the em (enitity manager) and emf (entity manager factory) my open cursor count climbs until I exceed the max number of open cursors on the database (11g RAC)
I'm committing the connection, and uow, and closing the em at the end of each call.
But until I close the emf, the open cursors aren't released.
TransactionhistoryPkg tranPkg = new TransactionhistoryPkg(conn); //Class created over database package via JPublisher
tranPkg.transactionhistoryInsSp(insertTrans.getCardId()); // executes db package
tranPkg.closeConnection();
conn.commit();
uow.commit();
uow.getAccessor().decrementCallCount();
em.close();
Am I missing something really obvious here??
btw - I found this link helpful in troubleshooting the max cursors issue: https://support.bea.com/application_content/product_portlets/support_patterns/wls/InvestigatingORA-1000MaximumOpenCursorsExceededPattern.html

Batch Updates with Toplink/JPA

Hi All,
I am new to JPA/Toplink and I wonder is there a way that we can do the batch updates/insertions using the JPA? If yes please help me how to do it?
My requirement is this, I need to fetch the n number of records from database and compare with the records from a file and insert/update/delete as required.
I don't wanted to do it one by one record but as a batch. Is there a way that I can do batch updates/inserts/deletes?
Any suggestion would be appreciated.
Thank you.

Hello,
I'm not sure how you are going to do the comparison as a batch and not record by record. A JPA query will give you objects back which you can use to compare and make changes to as neccessary. When you commit, the JPA provider will commit those changes to the database for you. TopLink/EclipseLink has options to efficiently comit those changes, even combining them into batches where possible. See http://wiki.eclipse.org/Optimizing_the_EclipseLink_Application_(ELUG)#How_to_Use_Batch_Writing_for_Optimization for details on using batch writing in EclipseLink.
Best Regards,
Chris

Joins with Toplink : Strange Problem!

Hi!
I'm trying get the data from EMP table where the column mgr (ValueHolderInterface instance in Toplink POJO) is a self referential key to the empno.
Now I want to execute a query like this :
SELECT t0.EMPNO, t0.ENAME, t0.JOB , t0.MGR FROM EMP t0, EMP t1 WHERE (t1.EMPNO = t0.MGR);
And I used ReportQuery to get this ;
see the following code
Session session = getSessionFactory().acquireSession();
ExpressionBuilder builder = new ExpressionBuilder();
Expression expression = builder.get("mgr").get("empno").equal(builder.get("empno") );;
ReportQuery query = new ReportQuery(Emp.class,builder);
query.addAttribute("empno");
query.addAttribute("ename");
query.addAttribute("job");
query.addAttribute("mgr",builder.get("mgr").get("empno"));
query.addAttribute("mgr",expression);
query.dontMaintainCache();
List<ReportQueryResult> results = (List<ReportQueryResult> )
session.executeQuery(query);
And the Toplink Generated SQL is :
SELECT t0.EMPNO, t0.ENAME, t0.JOB, t1.EMPNO FROM EMP t0, EMP t1 WHERE (t1.EMPNO = t0.MGR)
which is almost similar.
But I'm getting an exception as below:
Exception [TOPLINK-4002] (Oracle TopLink - 10g Release 3 (10.1.3.1.0) (Build 061004)): oracle.toplink.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: ORA-00904: "T0"."MGR": invalid identifier
Error Code: 904
Further ,
I tried to get the data from multile tables as below:
The intended SQL :
SELECT E.EMPNO,E.ENAME,E.JOB,E.MGR,E.SAL,E.DEPTNO,D.DNAME,D.LOC FROM EMP E, DEPT D WHERE E.DEPTNO=D.DEPTNO;
And for this I wrote the code as below :
ExpressionBuilder builder = new ExpressionBuilder();
Expression expression = builder.get("dept").get("deptno").equal( builder.get("dept").get("deptno"));;
ReportQuery query = new ReportQuery(Emp.class,builder);
query.addAttribute("empno");
query.addAttribute("ename");
query.addAttribute("job");
//query.addAttribute("mgr",builder.get("mgr").get("empno"));
// query.addAttribute("mgr");
query.addAttribute("ename");
query.addAttribute("sal");
query.addAttribute("deptno",builder.get("dept").get("deptno"));
//query.addAttribute("dept",expression);
query.addAttribute("dname",builder.get("dept").get("dname"));
query.addAttribute("loc",builder.get("dept").get("loc"));
query.dontMaintainCache();
//query.addAttribute("mgr",expression);
List<ReportQueryResult> results = (List<ReportQueryResult> ) session.executeQuery(query);
And the Query Generated by the Toplink is :
SELECT t0.EMPNO, t0.ENAME, t0.JOB, t0.ENAME, t0.SAL, t1.DEPTNO, t1.DNAME, t1.LOC FROM EMP t0, DEPT t1 WHERE (t1.DEPTNO = t0.DEPTNO);
which is perfect .
But the Toplink error message is :Internal Exception: java.sql.SQLException: ORA-00904: "T0"."SAL": invalid identifier
Error Code: 904
And I tried to do this using ReadAll Query as below :
The code I wrote is :
ExpressionBuilder builder =new ExpressionBuilder();
// Expression expression = builder.get("");
ReadAllQuery query = new ReadAllQuery(Emp.class,builder);
query.addJoinedAttribute("dept");
query.dontMaintainCache();
List results = (List) session.executeQuery(query);
The Toplink Generated SQL is :
SELECT t1.EMPNO, t1.ENAME, t1.JOB, t1.HIREDATE, t1.EMPDET, t1.SAL, t1.COMM, t1.DEPTNO, t1.MGR, t0.DEPTNO, t0.DNAME, t0.LOC FROM DEPT t0, EMP t1 WHERE (t0.DEPTNO = t1.DEPTNO)
And the error is :
Internal Exception: java.sql.SQLException: ORA-00904: "T1"."MGR": invalid identifier
Error Code: 904
What mistake am I making ?
The generated SQL from the Toplink is working fine, I tested it.. but the Strange error message given are puzzling me..
Could anyone point me where I'm wrong ?
Thanks in advance,
Samba.

Looks like you were trying to use the attributes being returned to define the query's selection criteria.
To find self-reference manager's in our shipped Employee example I can use:
        ExpressionBuilder eb = new ExpressionBuilder();
        ReportQuery rq = new ReportQuery(Employee.class, eb);
        rq.addAttribute("id");
        rq.addAttribute("firstName");
        rq.addAttribute("lastName");
        rq.setSelectionCriteria(eb.get("manager").get("id").equal(eb.get("id")));
        List<ReportQueryResult> results = (List<ReportQueryResult> ) session.executeQuery(rq);
    }and the generated SQL is: (note: multi-table mapping sith SALARY in use)
SELECT t0.EMP_ID, t0.F_NAME, t0.L_NAME FROM SALARY t3, EMPLOYEE t2, SALARY t1, EMPLOYEE t0 WHERE (((t2.EMP_ID = t0.EMP_ID) AND (t1.EMP_ID = t0.EMP_ID)) AND ((t2.EMP_ID = t0.MANAGER_ID) AND (t3.EMP_ID = t2.EMP_ID)))If you also add a direct query-key for the manager's id ('managerId') we can avoid the self join:
        ExpressionBuilder eb = new ExpressionBuilder();
        ReportQuery rq = new ReportQuery(Employee.class, eb);
        rq.addAttribute("id");
        rq.addAttribute("firstName");
        rq.addAttribute("lastName");
        rq.setSelectionCriteria(eb.get("managerId").equal(eb.get("id")));
        List<ReportQueryResult> results = (List<ReportQueryResult> ) session.executeQuery(rq);And the SQL looks like:
SELECT t0.EMP_ID, t0.F_NAME, t0.L_NAME FROM EMPLOYEE t0, SALARY t1 WHERE ((t0.MANAGER_ID = t0.EMP_ID) AND (t1.EMP_ID = t0.EMP_ID))Cheers,

How to Create and Remove CMP Entity with Toplink in same transaction??

Hi, i have a problem to create and delete cmp intances with toplink.
I create a entity bean and remove the same entity bean in the same transaction.
ie. my method have this code:
bean a = homeBean.create(pk);
a.remove();
bean a = homeBean.create(pk);
this code throws a javax.ejb.DuplicateKeyException
Toplink not remove CMP, execute the two calls of create first.
What configure toplink to support this case ??
Is this possible ??
I Can't controling the transaction manualy i'm using CMP entity beans with CMT.

BM,
If you want to import the utils package into your code, then the location of the utils package has to be in your CLASSPATH. JDeveloper uses libraries to define a project's CLASSPATH.
I'm not sure exactly what's going on here, but you might want to read the information about packages and class libraries in the online documentation. It's under:
User Guides

Toplink JPA LAZY loading in Java SE works without javaagent?

hi there,
I tought that mappings like
@JoinColumn(name = "join_col_name")
@ManyToOne(cascade=CascadeType.ALL, fetch=FetchType.LAZY)
private RelatedObject relObj;
with TopLink JPA in Java SE environment works ONLY with the
-javaagent:toplink-essentials-agent.jar
JVM parameter?
the strange thing is: I did 2 test runs, with and without the java agent parameter. I also could see that in the first case the weaver is working, in the second the property "toplink.weaving=false" is printed to the console BUT if I access the LAZY mapped attribute of the object instance it works in both cases - I expected a NullPointerEx. in the case without the javaagent.
Is there anything I missed?
Hans

Chris,
thank for for the tip about verifying lazy or eager fetching. The results are interesting - or better: confusing - to me:
I have built a test project with 3 entities:
Entity A hast @OneToMany to Entity B and
Entity B has ManyToONe to Entity C
A <-- B --> C
ALL relations are marked with FetchType.LAZY in all directions.
When I simply run the test project via main()-method out of eclipse, WITHTOUT specifycing a -javaagent parameter in the run dialog, I can confirm using your test case that the realtion IS LAZILY FETCHED.
So, I do not really know how this should work without the javaagent.
You mentioned statically weaved classed - is this the default case when no agent is present, how is it done? Toplink logging says that weaving is NOT active:
ServerSession(16821027)--Thread(Thread[main,5,main])--property=toplink.weaving; value=false
so how can the lazy loading work then?
regards,
Hans

Toplink JPA with Coherence deployment to Weblogic 10.3

Hi,
I have created an EJB application using Toplink JPA and Coherence. I would like to deploy this application to Weblogic 10.3.
During the startup of Weblogic I have specified the Java option as
-Dtangosol.coherence.cacheconfig=D:/JDEV_11g/jdeveloper/jdev/mywork/CoherenceApp/CoherenceProject/src/META-INF/coherence-cache-config.xml.
Persistence.xml and coherence-cache-config.xml are palced inside the jar file.
When I execute the ejb client program, during the method call, I can see that coherence is started but it uses the cache-config from the coherence.jar file instaed of the value I have set during startup. How can I make weblogic use my cache-config.xml? I have included the log file entries from server:

Hi Raji,
You mentioned:
>
-Dtangosol.coherence.cacheconfig=D:/JDEV_11g/jdeveloper/jdev/mywork/CoherenceApp/CoherenceProject/src/META-INF/coherence-cache-config.xml
>
and
>

>
It appears that these are conflicting; as the system property indicates that the config should be read from a file, whereas the file is actually deployed in a jar.
That being said, I would suggest double checking that the system property is actually being set in the JVM. In my testing, if I specify a cache config that does not exist, an exception will be thrown:
java -Dtangosol.coherence.cacheconfig=foo.xml com.tangosol.net.CacheFactory

Deployement problem in oc4j with hibernate + JPA and Spring

Dear All,
From last 2 days I am facing a problem in deployment of our application in oc4j client of oracle app server.
I am getting the following exception
Operation failed with error: [mkclsets:mkclsets] - Exception creating EntityManagerFactory using PersistenceProvider class oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider for persistence unit mkclsetsPersistenceUnit.When I am deploying the same application in tomcat app server its working fine. But I am unable to deploy the same in oc4j.
I am using the following technologies
Spring 2.0
Struts 2.0
Hibernate 3.3

Hi,
Thank you very much for your reply. the previous Exception has gone but now I get the following one.

Problem with standalone JPA

I have a stand-alone, non-WLS, utility Spring-JPA jar (jar contains its own META-INF/persistence.xml) that I use across several non-WLS applications. It's using the Toplink provider and works fine. When I attempt to use this jar within a Weblogic 10 war/ear environment, I see random behaviours. Specifically, upon start up of the server environment sometimes the Spring context appears to load all the Toplink entityManager/provider components, and sometimes it does not - in those cases, it appears that an OpenJPA entityManager gets loaded first and nothing works (many errors related to missing openjpa properties). When the Toplink pieces successfully load, all works as expected. It's almost as if the application is experiencing some race condition on what entityManager/provider is being loaded upon startup/deployment of the application.
Please help - I'm at a loss as to how to resolve this issue.
Thanks,

Hello,
Does this work if you set the <exclude-unlisted-classes> tag to true and list your classes in the persistence.xml as described in:
http://www.oracle.com/technology/products/ias/toplink/jpa/howto/java-se-usage.html
If it works, the problem might be with searching the persistence context for entities using a non-url classloader.

Chris

Can't create connection pool using weblogic 6.1 with Oracle thin driver

Hi !
I have tried to create a connection pool from adminconsole. My CLASSPATH setting

Hi Joe !
I didn't get what you would like to point out. Actully, I am using same config.,
but not to disclose the info. I gave you @test and username/password xxx/xxx.Ok. Now, assuming your pool looks like what I showed, the issue is probably
that there are multiple Oracle driver zips around, and your standlaone program
is using a different, newer, better one than the server. Our weblogic jar files
include a classes12.zip Oracle thin driver, but there are multiple versions of
classes12.zip, and the latest from oracle is better than the one we sealed into
our packaging. Please use jave -verbose to identify exactly which Oracle sip file
you are using in the successful case, then make sure this zip file comes before
any weblogic stuff in your weblogic server's classpath, so we'll use the same
driver. This should work. Edit the script you sue to start weblogic to verify
the classpath does end up with the oracle driver ahead of all weblogic stuff.

.MadhuriWell fine! That was easy. Your pool definition didn't have the same URL
or
user or password as this code. Try this for your pool definition:
weblogic.jdbc.connectionPool.thin=\

The key is in the log:

The DBMS driver exception was:
java.sql.SQLException: invalid arguments in call
at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:168)
Now we need to simplify the problem. Please make a simple 15-line
standalone
Java program like you'd find with the Oracle driver's examples, with
no
weblogic code in the picture. Just make a JDBC connection using Oracle's
driver, and show me that code. Then I can translate that into a pool
definition.

Toplink JPA Deployment problem in OC4J

Hi all ,
we are having problem in deployment for an toplink JPA program in OC4J 10.1.3 .. We are using toplink essesntial and our deployed EAR structure is
aaplication.xml
rmwtoplink.war
the content of application.xml is as
<display-name>rmwtoplink</display-name>
<module>
<web>
<web-uri>rmwtoplink.war</web-uri>
<context-root>rmwapplist</context-root>
</web>
</module>
the content of war file as below :
web-inf\web.xml
web-inf\classes\META-INF\persistence.xml
web-inf\classes\<classes>
web-inf\gnf\<jsp pages>
when ever a pages are called those do not use entity manager / jpa call are loading perfectly , but the pages which have used jpa are nt diplayed , we check the error messages , it just halts after following codes :
EntityManagerFactory emf =
Persistence.createEntityManagerFactory(jpaSource);
It seems there is no exception that is even thrown in page or opmn log .
The same program is running fine in Jdveloper 10.1.3 /
Is there any way where we can get the actual error message ?
we are using toplink.jdbc.url for connecting the database .

Here is little more insight for the problem , further check reveals that :
start connecting rmwtest
exception occured for connection test , Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
The Connection descriptor used by the client was:
//localhost:1521/ORCL
we do not have any idea how is localhost:1521/ORCL picked up , in our persistence.xml we have
where as rmwtest defined in persistence.xml as

Toplink\JPA vs JDBC - Toplink died for my app with 5000 users

Hi All Just a quick question about performance when comparing toplink jpa ans jdbc.
I have an app I just develpoed using toplink for all data acces that will have approx 5000 users and initial testing with 200 things look good. However after launch and going live for 5000 people the app blew up. Lot's of memory heap errors, and TopLink exceptions...
To make things work I have replaced all the toplink with traditional JDBC, this works but I am currious as to why toplink blew up? I notice when JDev creates the Toplink code that it never does any checking for open connections and never explicitly closes connections. Is this something that I have to do?
I should not that I was not using datacontrols directly, I created a datacontrol but then ised the FacesContext to create a list of results in the backing bean??
Anyway, I know that's not a great description but I thought I would throw this question out there and see what people had to say?
Thanks
J

It is hard to say where a memory issue occurred. Normally usage of a memory profiler such as JRockit JRA, or JProfiler is useful in debugging such issues.
There were a couple related memory issues in previous releases, so ensure you have the latest release or patch release.
Using an isolated (shared=false) or weak cache may also help.
In general you should be able to scale to 5000 users without any issues.

Problem creating deployment weblogic 5.1

I have weblogic 5.1 running on Win2K. I can start it up without

Generally we get this error when we did not packaged properly, like if use
tool win zip for packaging the bean.
1. when you are building EJB jar, please make sure that you have created a
directory "META-INF" with upper case letters
2. Make sure that you have deployment descriptors in 'META-INF".
3. Use Command line console, java command to package the bean like
"jar -cv0f".
ignore this mail, if you already done this way.
