Transaction integation with Toplink

xxx

Absolutely.
TopLink can manage its own TX directly using JDBC or make use of connections from an external connection pool (app server typically), which are involved with global TX. This is accomplished through JTA.

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.
tanks.

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
-> Working with JDeveloper

Using transaction activation policy together with TOPLINK Java object/relational mapping "commit and resume" transaction?

Has any one has experience using WLE transaction context together with TOPLINK Java

Bad performance when using complex database view with Toplink

Hi
Problem description
1. I have a complex query that collects the data from many DB tables. For this reason I create a database view based on this select. Using EJB 3.0 with Toplink I
mapped this view to a java object the same way I map database tables. The method I use to get the results is:
snippet code...
public List<VwKartela> VwKartela(Integer pperid) {
List<VwKartela> results = null;
Session session = getSessionFactory().acquireSession();
ExpressionBuilder bankfile = new ExpressionBuilder();
Expression exp1 = bankfile.get("perid").equal(pperid);
ReadAllQuery query = new ReadAllQuery();
query.setReferenceClass(VwKartela.class);
query.setSelectionCriteria(exp1);
results =(List<VwKartela>)session.executeQuery(query);
When running the select on the view prom SQL Plus I haven’t any performance problem.
2.Question: How can I improve the performance? I referenced to Toplink docs but I didn't improve the it.
Have anyone any experience is such cases?
Thank you
Thanos

Hi
After my last tests I conclude at the followings:
The query returns 1-30 records
Test 1: Using Form Builder
- Execution time 7-8 seconds
Test 2: Using Jdeveloper/Toplink/EJB 3.0/ADF and Oracle AS 10.1.3.0
- Execution time 25-27 seconds
Test 3: Using JDBC/ADF and Oracle AS 10.1.3.0
- Execution time 17-18 seconds
When I use:
session.setLogLevel(SessionLog.FINE) and
session.setProfiler(new PerformanceProfiler())
I don’t see any improvement in the execution time of the query.
Thank you
Thanos

Predeploy for PersistenceUnit failed - JBOSS with toplink essentials

I am trying to migrate my project from Tomcat 6 to Jboss-5.1.0-GA
I am using JPA 1.0 with toplink-essentials 2.0 for database process.
In tomcat it is working perfectly.
But when i am trying in JBOSS, it showing the below error..

1) Remove the "private static final long serialVersionUID = 1L;" from all pojos.
2) There should not be white space in persistence.xml inside <class> tag.
3) Change the JTA datasource from NON-JTA datasoucre.
I had changed all things as per the above mentioned points.
But still i am getting the same error.
Please verify the problem and suggest me a possible solution.
Please help me.. Please..

Hai jsutherl, Thank you for reply..
Right now cannot upgrade my project from toplink to eclipselink.
Because my project was an huge application. where i am using nearly 250 actionclasses and dao.
I already tried to migrate, but the package structures are completely different. so, i am unable to figure out this packages path.
So, as per your suggestion, i had renamed my orm.xml to mapping.xml file.
But when i am running the application then the below error was throwing....
19:03:30,149 INFO [STDOUT] [TopLink Warning]: 2013.05.01 07:03:30.119--java.lang.NullPointerException: null was thrown on attempt of PersistenceLoadProcessor to load class env.model.masters.IptNotifications. The class is ignored.[here IptNotifications is a database pojo refrence class where the db table name is IPT_NOTIFICATIONS]
The above same kind of error was throwing to all my pojos [i.e. Database table refrence classes]
Please help me.
I have to migrate my project to jboss.
All my work are getting stopped due to this issues.
Please help me..

Problems with Toplink integration with JTS and WSAD

We have a very strange problem.
Description:
     We are attempting to integrate with JTS, insuring that TopLink does its transactional activity within the scope of a JTS transaction, as described in the Foundation Library Guide.
     We have a stateless session bean, a method of which implements a simple "insert" on a database table registerObject() on a unit of work). This bean is configured to use bean-managed transactions, but with a default resolver of rollback.
     The bean is launched in the WSAD test environment.
     When the bean method is invoked from the WSAD Universal Test Client (web app that runs in the same app server allowing discovery and unit test of bean methods), the code works. A row is inserted into the table, etc.
     Same code, same method, same (stateless) bean, same instance of the WSAD test environment, if the bean method is invoked from outside the application server (via a JUnit test driver that discovers the session bean via JNDI), the code breaks. The final JTS commit catches a javax.transaction.RollbackException, apparently without any sort of stack trace tacked to the exception printStackTrace() doesn't result in anything). No row is inserted.
     We can call the bean alternately, via these two approaches, under the same instance of test environment, and get different behavior.
     We don't understand. All (hopefully) of the relevant details follow.
We are using:
     WSAD Version: 5.0.1 Build id: 20030423_1316
     TopLink - 9.0.3.3 (Build 430)
     Oracle 9i
From our sessions.xml:
     <login>
          <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
          <datasource>project</datasource>
          <platform-class>oracle.toplink.internal.databaseaccess.OraclePlatform</platform-class>
          <uses-external-connection-pool>true</uses-external-connection-pool>
          <uses-external-transaction-controller>true</uses-external-transaction-controller>
     </login>
     <external-transaction-controller-class>oracle.toplink.jts.was.JTSExternalTransactionController_5_0</external-transaction-controller-class>
From our project XML:
     <uses-external-connection-pooling>true</uses-external-connection-pooling>
     <uses-external-transaction-controller>true</uses-external-transaction-controller>
The code that breaks:
     SessionManager sm = SessionManager.getManager();
     Server ss = (Server) sm.getSession("project", TestBean.class.getClassLoader());
     ClientSession cs = ss.acquireClientSession();
     Context c = new InitialContext();
     UserTransaction t = (UserTransaction) c.lookup("java:comp/UserTransaction");
     t.begin();
     UnitOfWork u = ss.getActiveUnitOfWork();
     u.registerObject(value);
     u.commit();
     t.commit(); /* this throws javax.transaction.RollbackException */
Thanks.

Strange problem, could be a Websphere issue, or an issue with the JTSExternalTransactionController_5_0.
Try configuring TopLink to not use JTS and see if the same problem still occurs. Also turn on TopLink logging and exception logging and your Websphere server logging to see if you can get the real exception and stack that is causing the RollbackException.
This could be an issue with the JTSExternalTransactionController_5_0 as the original version of the controller did have a JTS issue. Make sure you are no the latest patch and check with support to see if they have a patch for this problem.

XA transactions timeout with essentials / eclipselink

I'm attempting to do an XA (container managed) tranasction throught a series of remote EJB calls. Database is 11g
When the JPA provider is toplink-essentials or EclipseLink the the end of the 2PC hangs. Eventually it times out with an "Error allocating connection". Monitoring of the connection pool shows there are lots of free
However this work with Hibernate 3.
How do I use XA transactions on 11g with toplink/eclipselink.

Thanks for looking at this. I can send a full code sample if needed. Sorry for the full stack traces.
The Setup
There are three parts to my application.
+1) an ejb which writes "Nice Weather" to the database+
+2) an ejb which calls the nice weather remotely then returns "Hello World"+
+3) a junit test which connects to the ORB of the "HelloWorld" which in turn calls the "NiceWeather"+
Using Toplink-essentials and ojdbc6.jar
The database user has all grants/admin/privileges. Assigned by clicking on the Grant ALL and Admin All in the SQL developer edit user.
In NiceWeather ejb the persistence.xml looks like
+<?xml version="1.0" encoding="UTF-8"?>+
+<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">+

+<property name="toplink.logging.logger" value="JavaLogger"/>+
+<property name="toplink.logging.level" value="FINEST"/>+
+</properties>+
+</persistence-unit>+
+</persistence>+
the Connection pool backing jdbc/helloRemoteEJB looks like

Datasource Classname: javax.sql.XADataSource
Resource Type:    javax.sql.DataSource javax.sql.XADataSource
User: example
password: example

Passing Case
When run with both components (HelloWorld-ejb and NiceWeather-ejb) deployed on the same Application Server instance (Glassfish v2ur2) the tests pass and everything is happy
the log messages for the NiceWeather-ejb are:

Hot delpoyment with TopLink and Stateless Session Beans

What is the recommended procedure for making hot deployment of Stateless session beans work with toplink in WLS 7.0sp1 and oc4j (9.0.3)
My current setup is as follows using WLS 7.0sp1:
A stateless session bean is accessing toplink enabled persistent java classes via the SessionManager. I'm currently using the class loader of the stateless session bean:
* Method in stateless session bean
* Return the TopLink Session (based on the wls stateless session bean demo)
public Server getSession() {
return (Server)SessionManager.getManager().getSession("ejb_sessionbean", this.getClass().getClassLoader());
Everything is working as such. My session bean can read and write the persistent java classes. However if I redeploy the stateless session bean jar file the toplink session is not reinitalized. This means that new settings in the session.xml are not used. I addition I get other errors.
I'm having toplink on the server classpath. The toplink enabled persistent classes are in the stateless session bean jar file.
Thanks
Henrik

This is a recent post note I found on the same topic:
It all hinges on whether the TopLink ServerSession class has
been loaded by a classloader which is actually thrown away
during the hot deployment process. If this is the case, then
hot deployment causes the ServerSession to go out of scope
and finalize methods take care of logging it out properly.
If you deploy your TopLink Project on the Sytem class path then
it definately won't work. You'd have to restart the server every time.
But if the TopLink Project is deployed inside of an .ear file
and if you pass the correct ClassLoader to the
SessionManager.getSession( .... ) call then TopLink Session will
be re-started when you hot deploy the .earBased on this, the solution might be to deploy your EJBs in an ear file. Everything else looks OK. Can you try this and let us know?
Thanks,

Error while deploying Spring PetClinic Demo App(with Toplink OR )on OC4J

Hi All,
I am trying to deploy sample app provided with spring framework on oc4j with Toplink as my OR layer, but i am facing issues with the deployment
App fails to start with error finding "org.springframework.orm.toplink.support.CommonsLoggingSessionLog"
this is found in toplink-applicatio context.xml file
i found that this class is missing in spring framework.
please help to get the jar files
Thanks
Raghavendra

i got the class files. actually in 10.1.3 these class files are put in a different jar file spring-toplink.jar
The Main issue here is that 10.1.3 toplink production is yet to be integrated into spring 2.
petClinic will work fine if we use 10.1.3 developer preview edition
Thanks
Raghavendra

How to preset fields in a transaction BP with default values

Hi!
I want to fill few fields in transaction BP with default values.
This should be if there`s a new business partner to insert.
If i can do this depending on the selected role it was the best
First i thought on SPA/GPA-parameters ... but then i can`t do it in depence on the selected role.
In customizing i can tell only if a field should be displayed or not, for input or not, ... but no values to insert.
Is here anybody with a good idea for me?
I`ve posted my question first in crm-section but i think here it`s better
Thanks a lot in advance.
Best regards,
Ingo

Hi,
There is one possibility which requires an enhancement of the
BDT event ISDAT and a call to the function module
BUP_BUPA_FIELDVALUES_SET. This means that an ISDAT function module needs to be written (transaction BUS7) which calls the function module BUP_BUPA_FIELDVALUES_SET with the needed values that are to be defaulted. You can read the role value using BUS_PARAMETERS_ISSTA_GET (T_RLTYP).The fields which are possible can be found in the DDIC structure BUSDEFAULT. However this is limited only to the fields inside this structure.
Thanks and warm regards,
Smita.

What's the data type when defining a KF to show an integer with a sign?

We want show some days difference which should be an integer with either a positive or negative sign. I used to design a KF with type of Number with "DEC - Counter or amount field with comma and sign" as the Data Type, but find it shows 25.000 if the day difference is 25 days. We want to show it as 25 other than 25.000. Then what type would we pick when defining the KF? Use Integer as the type? But we also want it to show the sign symbol.
The type field is dimmed as long as the InfoObj. is activated that I have to remove this field. I've delete all the data loaded in ODS, PSA and etc., and I have successfully remove this KF from InfoSource, but when I try to remove it from the ODS, always get the msg "Can't move/delete locked InfoObjects" even if the InfoObject is not locked (I've tried SM12 to delete all locked entries and also tried relog on, but not helpful). If someone gives any idea, I would be very appreciated on how to remove this KF from ODS and also let me what type should I use when creating a new KF which only shows integer with a sign!
Thanks

hey Siggi,
Now after I right click the ODS and select "Delete Data", the KF eventually gets removed from the ODS without any error, then I continue to delete this InfoObj.
However, when I run the InfoPackage to load data to the ODS, get a msg (see below in between two dashed lines):
Syntax error in GP_ERR_RSDRO_UPDATE, row 1,210 (-> long text)
Message no. RG102
Diagnosis
The data object "I_S_OLDDATA" does not have a component called "/BIC/Z_field".
Where Z_field is the InfoObject we deleted. With this error, that's even worse since that stops any data coming in! How to get rid of this error that we can continue to load data?
Thanks
