Calling Glassfish jdbc Datasorce in EJB 3.0 with @Resource annotation.

I tried EJB 3.0 with netbeans and glassfish and "{color:#ff0000}+_ORACLE_+{color}". I wanted to link the oracle database to GLASSFISH server and I followed the instructions.After I clicked 'ping' button, it displayed as *{color:#339966}'PING SUCCEED".{color}*
But I couldn't call my datasource from the eje stateless session bean with @Resource annotation.It resulted a dependency injection exception. Can some one tell me how to do this properly.
{color:#ff0000}Thanks in Advance!!!!{color}

Frank, yes, I can modify if it is necessary the datasource but, how can I say in the xxxx-jdbc.xml not to use JTA transactions when this data source is called inside a ejb 3.0 method?
I'm using Jdev11g and the integrated Web Logic Server.
Thank's

Thread hang during call EJB 3.0 with Weblogic 10.3 (Urgent)

Hello,
We have a java client application call Weblogic Appserver 10.3, EJB 3.0 Service. Occasionally, client application, some step will get hang when try to invoking EJB. When we restart the application server and re-run the client application, it may work or hang on any other step. (Totally, we have around 40 steps to invoking EJB service)
We did check Google and find similar issue happen on the IBM Websphere appserver. They post a patch to fix this issue (http://www-01.ibm.com/support/docview.wss?rs=180&uid=swg1PK74719), but not Weblogic.
Is there any Weblogic expert who can help me to solve this issue?
I have attached two thread dumps (different steps) when they got hang.
Appreciate your quick help.
Best wishes,
Feelyn

JDBC, JMS and EJB transactions - possible problem?

Hello,
          I am using Oracle 9, Weblogic 8.1 SP 4, MyEclipse and
          XDoclet.
          In my current project I have the following piece of code
          in one of my message driven beans (code cited as pseudocode
          without unnecessary details):
          * @ejb.bean name="MyMessageProcessor"
          * display-name="Display name for a MyMessageProcessor"
          * jndi-name="ejb/MyMessageProcessor"
          * description="Bean MyMessageProcessor"
          * destination-type="javax.jms.Queue"
          * transaction-type="Container"
          * acknowledge-mode="Auto-acknowledge"
          * subscription-durability="Durable"
          * generate="false"
          * @ejb.transaction type="Required"
          public class MyMessageProcessor implements MessageDrivenBean, MessageListener {
          public void onMessage(Message msg) {
               try {
                    //obtaining connections to two different databases via JNDi
                    java.sql.Connection connOne =
                    ((DataSource)ctx.lookup("DataSourceOne")).getConnection();
                    java.sql.Connection connTwo =
                         ((DataSource)ctx.lookup("DataSourceTwo")).getConnection();
                    // performing some UPDATEs and INSERTs on connOne and connTwo
                    // calling some other methods of this bean
                    //creating the reply JMS message and sending it to another JMS queue
                    Message msgTwo = this.createReplyMessage(msg)
                    this.queueSender.send(msgTwo);
                    //commiting everything
                    this.queueSession.commit();
               } catch (Exception ex) {
               try {
                    if (this.queueSession!=null) this.queueSession.rollback();
               } catch (JMSException JMSEx) {};
               this.context.setRollbackOnly();
          Some days ago (before the final remarks from my client) there used to be only one DataSource configurated on the basis of the
          connection pool with non-XA jdbc driver. Everything worked fine
          including the transactions (if anything wrong happend not only wasn't the replymessage sent, but also no changes were written
          to database and the incomming message was thrown back to the my bean's
          queue).
          When I deployed the second DataSource I was informed by an error message, that only one non-transactional resource may
          participate in a global transaction. When I changed both datasources
          to depend on underlying datasources with transatcional (XA) jdbc drivers, everything stopped working. Even if
          EJB transaction was theoretically successfully rolledbacked, the changed were written to the database
          and the JMS message wasn't resent to the JMS queue.
          So here are my questions:
               1. How to configure connection pools to work in such situations? What JDBC drivers should I choose?
               Are there any global server configurations, which may influence this situation?
               2. Which jdbc drivers should I choose so that the container was able to rollback the database transactions
               (of course, if necessary)?
               3. Are there any JMS Queue settings, which would disable the container to send message back to the
               queue in case of setRollbackOnly()? How should be the Queue configurated?
          As I am new to the topic and the deadline for the project seems to be too close I would be grateful
          for any help.
          This message was sent to EJB list and JDBC list.
          Sincerely yours,
          Marcin Zakidalski

Hi,
          I found these information extremely useful and helpful.
          The seperate transaction for sending messages was, of course, unintentional. Thanks a lot.
          Anyway, I still have some problems. I have made some changes to the
          code cited in my previous mail. These changes included changing QueueSessions
          to non-transactional. I also set the "Honorate global transactions" to true.
          I am using XA JDBC driver. After setting "Enable local transactions" to false
          (I did it, because I assume that JDBC transactions should be part on the global
          EJB transaction) I got the following error:
          java.sql.SQLException: SQL operations are not allowed with no global transaction by default for XA drivers. If the XA
          driver supports performing SQL operations with no global transaction, explicitly allow it by setting
          "SupportsLocalTransaction" JDBC connection pool property to true. In this case, also remember to complete the local
          transaction before using the connection again for global transaction, else a XAER_OUTSIDE XAException may result. To
          complete a local transaction, you can either set auto commit to true or call Connection.commit() or Connection.rollback().
          I have also inspected the calls of methods of bean inside of onMessage() method just to check, whether
          the transactions are correctly initialized (using the weblogic.transaction.Transaction class).
          My questions are as follows:
          1. Any suggestions how to solve it? I have gone through the google answers on that problem and only
          thing I managed to realize that JDBC must start its own transaction. Is there any way to prohibit it
          from doing that? Can using setAutocommit(true/false) change the situation for better?
          2. How to encourage the JDBC driver to be a part of EJB transaction?
          3. As I have noticed each of ejb method has its own transactions (transactions have different
          Xid). Each method of the bean has "required" transaction attribute. Shouldn't it work in such
          way that if already started transaction exists it is used by the called method?
          4. The DataSources are obtained in my application via JNDI and in the destination environment I will have slight
          impact on the configuration of WebLogic. What is least problematic and most common WebLogic configuration which would
          enable JDBC driver to participate in the EJB transaction? Is it the WebLogic configuration problem or can it be
          solved programmically?
          Currently my module works quite fine when "enable local transactions" for DataSources is set to true, but this way
          I am loosing the ability to perform all actions in one transaction.
          Any suggestions / hints are more than welcomed. This message was posted to jdbc list and ejb list.

JDBC transactions in EJB 3.0

We have an EJB 3.0 method that call some jdbc DAO methods. This DAO methods called from controller (servlet) works fine, but when called from EJB method raise the following exception:
"java.sql.SQLException: Cannot call Connection.commit in distributed transaction. Transaction Manager will commit the resource manager when the distributed transaction is committed."
I think it is a JTA related error. I don't want to use JTA because I can't modify DAO (its a third party library).
I've tried annotation @TransactionAttribute(value=SUPPORTS) in the EJB method without success.
There is anyway to say EJB 3.0 not use JTA?
Thank's

Frank, yes, I can modify if it is necessary the datasource but, how can I say in the xxxx-jdbc.xml not to use JTA transactions when this data source is called inside a ejb 3.0 method?
I'm using Jdev11g and the integrated Web Logic Server.
Thank's

Servlets/JDBC vs. servlets/EJB performance comparison/benchmark

I have a PHB who believes that EJB has no ___performance___ benefit
against straightforward servlets/JSP/JDBC. Personally, I believe that
using EJB is more scalable instead of using servlets/JDBC with
connection pooling.
However, I am at a lost on how to prove it. There is all the theory, but
I would appreciate it if anyone has benchmarks or comparison of
servlets/JSP/JDBC and servlets/JSP/EJB performance, assuming that they
were tasked to do the same thing ( e.g. performance the same SQL
statement, on the same set of tables, etc. ).
Or some guide on how to setup such a benchmark and prove it internally.
In other words, the PHB needs numbers, showing performance and
scalability. In particular, I would like this to be in WLS 6.0.
Any help appreciated.

First off, whether you use servlets + JDBC or servlets + EJB, you'll
most likely spend much of your time in the database.
I would strongly suggest that you avoid the servlets + JDBC
architecture. If you want to do straight JDBC code, then it's
preferable to use a stateless session EJB between the presentation layer
and the persistence layer.
So, you should definitely consider an architecture where you have:
servlets/jsp --> stateless session ejb --> JDBC code
Your servlet / jsp layer handles presentation.
The stateless session EJB layer abstracts the persistence layer and
handles transaction demarcation.
Modularity is important here. There's no reason that your presentation
layer should be concerned with your persistence logic. Your application
might be re-used or later enhanced with an Entity EJB, or JCA Connector,
or a JMS queue providing the persistence layer.
Also, you will usually have web or graphic designers who are modifying
the web pages. Generally, they should not be exposed to transactions
and jdbc code.
We optimize the RMI calls so they are just local method calls. The
stateless session ejb instances are pooled. You won't see much if any
performance overhead.

HOW TO CALL A WEB SERVICE OR EJB FROM BPEL

HI
i want to call java web service or ejb from my bpel process. how can i do this.
i am using oracle soa10.1.3.1.0 and jdeveloper 10.1.3.1.0 and oracle database xe 10g.
thanks in advance K ROY

You could deploy your EJB or Java under a web service into your OC4J, after that, you invoke a partnerlink from BPEL to the destination of wsdl will do. Also don't forget to add in your XSD schema as well.
Thanks,
Jyno

Error with Asynchronous RFC call to JDBC

Hi all,
We are working on a scenarion where in we have to make an asynchronous RFC call to JDBC.
We have configured RFC sender adapter following this weblog
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
We have created data types only for the database as RFC does not require any data types.
And also we have created message types,message interfaces accordingly.
In Message Mappping,we mapped the export parameters of RFC to the access fields of database message type.
Also we have created sender agreement,interface determinations etc.... accordingly
And for sending RFC request asynchronously we followed this weblog
/people/swaroopa.vishwanath/blog/2006/12/28/send-rfc-to-sap-xi-150-asynchronous
Once done with all the above steps we could able to trigger the RFC call and caught with the following errors in SXMB_MONI and no errors are seen in communication monitoring

Can any one please let me know what other configurations do we need to do?
I did not map the RFC import parameters,do we need to do that
Any help in this regard is really appreciated

Hi,
I am really happy to hear that the problem with mapping is resolved.
Now as per your requirment It needs to be aynschornous RFC--> XI ---> JDBC call. In XI you should map the RFC Export parameters to the traget structure of JDBC.
then the question is to how to trigger the RFC Function Module in R/3 to XI.
Plesae follow below steps to trigger it from SAP R/3
1. Create a RFC in the R/3 system
2. Configure the SM59 and Sender Communication channle as given in the Michal's blog. Also test if it is succesful.
/people/michal.krawczyk2/blog/2005/03/29/configuring-the-sender-rfc-adapter--step-by-step
3. Import the RFC in XI
4. Do the mapping to the target strucutre
5. Configure the JDBC receiver adapter
/people/sameer.shadab/blog/2005/10/24/connecting-to-ms-access-using-receiver-jdbc-adapter-without-dsn
6. You can trigger the RFC from R/3 sytem by using
Async Call - in ABAP program use below syntax to call RFC. Here the export parameters will be passed on to XI which further have mapped to JDBC.
CALL Function "RFC Name" IN BACKGROUND TASK destination <sm59 destination>
COMMIT WORK.
Sync Call
CALL Function "RFC Name" destination <sm59 destination>

Javax.ejb.ObjectNotFoundException: Bean with primary key '555' was not foun

When I delete a particular entity bean instance, i get the following exception:
javax.ejb.ObjectNotFoundException: Bean with primary key '555' was not found by 'findByPrimaryKey'.
But, the instance is being deleted from the database.
Anyone please help,
Thank u,
Seshu

Greetings,
When I delete a particular entity bean instance, i get
the following exception:
javax.ejb.ObjectNotFoundException: Bean with primary
key '555' was not found by 'findByPrimaryKey'.Interesting. How is your client calling the bean's remove method? Directly or through its home? Is it calling findByPrimaryKey before or after the call to remove? What is the PrimaryKey class type of your bean? Is the client passing a correct instance? All are things to be considered when troubleshooting your application. If more assistance is required, then seeing the relevant source code would be more helpful.
But, the instance is being deleted from the database.As is generally to be expected. No?
Anyone please help,
Thank u,
SeshuRegards,

Subclassed EJB with RolesAllowed annotation not giving permission

A servlet is calling a method of an EJB (name EJB B). EJB B is a sub class of EJB A which contains the method and is not overridden by EJB B.
EJB A uses the annotation @RolesAllowed({"user","system","admin"})
EJB B uses the annotation @RolesAllowed({"system"})
When the call is made by the servlet the following error is produced:
JBAS014134: EJB Invocation failed on component EJB B for method xxxx: javax.ejb.EJBAccessException: JBAS014502: Invocation on method: xxxx throws exception of bean: EJB B is not allowed
If I replace the EJB A annotation with @PermitAll then the method is called without the permission problem.
I am wondering why the 'system' role allowed in EJB A is ignored in the annotation and the exception is thrown.
Is this a bug perhaps?

Hi Jay Bhaiya,
I am getting the correct output by following the below:
1: Change the SecurityRolesImpl.java to provide the below role that can access the EJB method:
*@RolesAllowed({"TestRole"})*
2: Then build the service as normal using the same build.xml
3: Do not depoly the EAR using ant and try to use the Admin Console to deploy the EAR.
4: While deploying the application through the admin console choose the below option:
Custom Roles: Use roles that are defined in the Administration Console; use policies that are defined in the deployment descriptor.
5: Then create the client stubs using the build.xml
6: Then go to the Admin Console.
Security Realm >> my realm >> users and Groups >> create a user TestUser ( pass- TestUser).
7: Then Click on the RolesAllowedEar under the depolyments tab.
Click on Security >> Roles ..
Create a New Role >>> TestRole.
Click on the Role created (TestRole) >>> Add Condition >>>
Within Add Condition >> select User >> NEXT >>>
Enter TestUser >>> Click ADD .
Click Save.
Now try to access the Web Service using the client code.
Thanks,
Sandeep

A Tip for using EJB 3.0 with WebLogic Ant Tasks

I started out writing this up as a problem, but then I found the answer so I'm, posting a tip instead.
When I tried to write an EJB [stateless] using EJB 3.0 in my legacy Weblogic ear project I started getting this error:
<pre>
No EJBs found in the ejb-jar file 'test'. Please ensure the ejb-jar contains EJB declarations via an ejb-jar.xml deployment descriptor or at least one class annotated with the @Stateless, @Stateful or @MessageDriven EJB annotation.
</pre>
This is why: wlcompile will put the class files in the App-Inf/classes directory unless it finds an ejb-jar.xml file in the META-INF directory for the module it is working on. With EJB 3.0, I wasn't using an ejb-jar.xml file because it was unnecessary. Later, Appc runs and it complains <b>because there are no classes module directory, they went into the shared ear folder instead.</b>
Here's I how it working again: Use javac [not wlcompile] to compile the EJB 3.0 module and make sure that the class files go into the correct module directory. Then you can use wlappc to generate all the associated files for the EJB. I have sucessfully deployed an ear file that uses both EJB 2.x and EJB 3.0 with this approach.
I wish Weblogic's own ejb3.0 sample application used their split directory deployment.
Good Luck.
John Aronson

Hi John,
I am working on development an enterprise application using EJB 3.0 on Weblogic 10.
While developing, I am keeping all my classes (from ejb's as well as web) into APP-INF/classes directory. It is working fine for Web and ejb 2.0 packages, but ejb 3.0 packages, I get the following error when I keep my ejb 3.0 beans classes in APP-INF/classes directory.
No EJBs found in the ejb-jar file 'customer'. Please ensure the ejb-jar contains EJB declarations via an ejb-jar.xml deployment descriptor or at least one class annotated with the @Stateless, @Stateful or @MessageDriven EJB annotation.
One solution is to keep the classes under customer ejb directory, but I wan tto keep all the classes in APP-INF/classes directory so that when using Eclipse IDE I can output all compiled sources into APP-INF/classes directory.
Has anyone faced this situation? Any suggestions to fix this issue?

Here's a good free e-book but without Netbean. It covers everything you would need to know about EJBs.

The question is too vague to be answered. It's a design decision that needs more details.

I can no longer receive or send calls because i need to restore my iphone with itunes how do i do this?

The back of my iphone 4 got smashed and it worked fine for about 3 hours.
Then in the top left corner of my screen where normaly my service bars are, it said "searching".
And i could no longer make/receive any calls and my phone is completely unconnected to my 3G network.

If you have the computer that you first setup the phone with iTunes then just connect the phone to that computer via. the USB cable and see if a sync can be done.
