Spring 2.5.5 and EJB 3.0 Deployment problem in WLS 10.3
Hi,
I am attempting to deploy a EAR file that previously ran on SJSAS 9.1 update 1 to WLS 10.3. As part of the deployment I get the following error related to the EJB3 classes.
There are 1 nested errors: weblogic.j2ee.dd.xml.AnnotationProcessException: [EJB:015002]Unable to load class au.edu.cqu.cis.web.ajaxservice.AjaxServicesBean in Jar D:\dev\env\oracle\middleware\jdeveloper\system\system11.1.1.0.31.51.56\DefaultDomain\servers\DefaultServer\tmp\_WL_user\ProgEnrol-ear-3\v540rk\ProgEnrol-ejb-3.0.4-SNAPSHOT.jar : java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy
I suspect that this is related to the @Autowired spring annotation in use in the session bean. Either, the server is not finding the Spring JAR correctly or it has a problem with the annotation.
Can anyone point me in the right direction? Do I need to deploy the spring jar as a library?
Thank you.
Regards,
Graeme.
Hi, Graeme.
Seems there is an existing CR on something related from v10.0: CR353213
* WLS 10.0 - EJB 3.0 deployment fails when parsing class for Stateless annotation
According to http://edocs.bea.com/wls/docs103/issues/known_resolved.html, this is not addressed in 10.3
Closely review your classpath, and then (assuming you have access to the source) review the body of your ejb. If it is related to this CR, you may be able to workaround the issue by shortening the body and split large methods into more sub-methods.
I hope this helps,

General install and deployment problem with WLS clustering on two boxes
Hi,
I've come across a general installation problem with WLS with a cluster spanning two different physical machines and two Managed Servers, one Managed Server per physical machine.
The problem is, starting from scratch, you install WLS on both physical machines. You can then use the config wizard to create the domain, cluster and managed servers, but this is a manual typing in process.
So we've now got a WLST Script which we run with "java weblogic.WLST domaincreate.py domain.properties". This is good as it creates the domain, cluster, managed servers and JMS modules.
Now the trouble is, it doesn't do anything to the 2nd physical machine which will be running only the 2nd Managed Server.
One dirty way to get around this in order to start the 2nd managed server was to copy the domain directory to the 2nd server, but I'm sure this is bad practice and what you can actually do is improve the WLST script to actually, but the same as the config wizard and dump the nessary information to the 2nd physical machine in order so you don't need to copy the domain directory across so that it will startup straight after running the WLST.
Any help appriecated.
Surfbum.Hi I think I've found the answer. You can build a managed server template using the pack command.

Adf faces command button, bindings and ejb 3.0 persisting problem

I just started learning EJB3.0. I created a slsb application very similar to the converter available in the tutorial sample. However when i build and deploy the app I am getting this error ->This application client has no ejb refernce by the name simpleSessionRemote. This happens when I have app-client jar inside the ear. For only jar and war inside the ear there is no deployement problems. I am using NetBeans 5.5 and Sun App server. Anyone has come across similar issue?
How are you looking up the remote ejb dependency in the app client -- via @EJB or InitialContext()?
Please post the source code for the app client, the full error message/stack trace, and any of the following files that exist in the .ear : sun-ejb-jar.xml, application-client.xml, sun-application-client.xml, ejb-jar.xml .

Hi,
Does javafx 2.0 supports ejb injection. I am trying to inject ejb using annotation in fxController. It is simply not recognizing class ejb. Is it supposed to be done in old fashioned way using Service Locator.
Could someone direct me to the literature related with javafx 2.0 and ejb.
Thanks
SaradHi Sarad,
Injecting stuff (whether it is via EJB or Spring or whatever) usually requires that the bean is loaded (i.e. newed) via some context. In FXML the Controller is created via the FXMLLoader so unfortunately you can't easily inject into it. This is a bit of a problem for a few of us and there is an open feature request being considered for future releases: http://javafx-jira.kenai.com/browse/RT-16724. You may want to up-vote if this is important for you.
At this stage of the game I would suggest your best bet is to have your controller look up your EJB via JNDI (as per the unit test in http://openejb.apache.org/3.0/injection-of-other-ejbs-example.html) and then have your controller delegate calls onto the EJB. You will likely want to thread the calls onto this as well, using JFX's Task or Service.
Hope that helps,
zonski

I am fed up with Spring and Apple passing me off to one another and neither will fix the problem. I am unable to receive a connection on my phone.
The internet goes out and I have to reset network setting each and every time. This is only a temporary solution which by the time I release the line with Spring or leave the apple store the issue is back. Sprint indicates that it is a know issue with the Iphone 5 and apple says it is a network issue as Sprint's network is not up to par with the Iphone and can not meet the expectations on the Iphone 5.
I have attached a few picture, as you can see it clearly says I have 5 bars and 3g available but I have no connections what so ever.
This issue affects all data and so I can not send or receive picture messages, use apps, or access the internet. The data goes in and out intermittently and it seems the phone chooses what I can and can't do.
For example I can watch Youtube or Vevo videos but I can not access Facebook or Instagram.
Is anyone else having this issue?
I will soon loose my patience....
I have reset my phone three time and have reset network and other setting mutltiple times. -

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 ZakidalskiHi,
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.

OC4J 9.0.3 and EJB 1.1 deployments???
I can not deploy my ejb1.1 beans on 9.0.3 container.
OC4J crashes with an XML parse error as a null pointer exception.
If I remove my O-R mappings from my orion-ejb-jar.xml file, the container starts up ok (app wont run as it needs the mappings)
9.0.3 docs claim I should be able to use my 1.1 ejb in this ejb 2.0 container.
Solaris release notes for 9.0.3 claim I must migrate to ejb2.0
Someone else posted this same question but got no replies.
Anyone else deployed ejb1.1 with OR mappings in 9.0.3 successfully yet?
thanksI have tried migrating to an ejb2.0 set of beans and ejb-jar.xml file.
With no <query> tags installed for my finders I notice that a typical finder produces this:
<!-- Generated SQL: "select Isp.isp_Id from Isp -->
This is vastly different from the 1.1 orion-ejb-jar.xml which would list ALL column names in the finder - hence how am I going to do a findAll? The currently generated sql is way off. Deployment of the "ormap" demo also shows a lack of column names in the generated SQL finder methods in orion-ejb-jar.xml.
Further, as soon as I introduce the query in the 2.0 version of ejb-jar.xml, the container dies with a null pointer exception. Removing this from the ejb-jar and bean deploys. Useless, cause theres no finders though.
Also, attempts to add to the <finder-method query=...> tag yield container crashes with null pointers too.
This is not very robust to say the least. Can you provide names of jar files that would cause such exceptions?
When NO query tag is inserted in the ejb-jar file, attempts to run a sample client using findByPrimaryKey return successfully but use of findAll causes timeouts similar to whats described in
"finders giving "timeout expired waiting for an instance" after 0, 1, or 2 calls" in this same forum.
Heres the query out of the ejb-jar.xml file...
<query>
<query-method>
<method-name>findAll</method-name>
<method-params></method-params>
</query-method>
<ejb-ql>
SELECT OBJECT(o) from IspTb o
</ejb-ql>
</query>
IspTb is the <abstract-schema-name> Tables exist in db.
The full error...which prevents deployment of the ejbs and hence no rewrite of the orion-ejb-jar file.

Deploying EAR and EJB (ClassLoader Question)
Hi,
Have a few queries. Appreciate any quick answers.
(a) To deploy a EAR or EJB jar to WebLogic server, is it necessary to include the jar location specifically in $CLASSPATH?
I think not. Am I correct?
(b) Is the bean/EAR deployed at module level? Is there a setting for this - is it at bean deployment descriptor? Where can I find this?
If (say) I need to update an EJB, do I un-deploy, update and re-deploy it?
Or must I restart the entire WLS container?--> An EAR includes one or more EJB files. You don't need to specify the location because it's contained at application.xml file inside the EAR.
--> Each bean has a deployment descriptor. You can see it at META-INF directory
If you need to update an EJB (that it is not part of and EAR), you are right.
The WLS container not need to be restarted.

Had nebody used Swing for GUI and EJBs for business logic. HEre i need to use Swing for gui rather than JSPs.
Can nebody help??My question is ...
How do u call EJBs from swing based applets..
In J2EE transaction management cud be done at server side but how will we manage with the swing app?? -
OC4J EJBQL and EJB 2.0 features
Hello Debu Panda and All
I've got all howtos and I mangaged to get some parts of OC4J [Oracle9iAS (9.0.3.0.0) Containers for J2EE (build 020323.1689)] working.
There are still some issues that are stalling our development. Could you please comment on them, maybe providing an estimate of when they will be solved/implemented?
First of all, a little background. Our application uses many Java Swing application clients that connect to the EAR application in the container.
The ear application has the following structure:
All database access (Oracle 8i, located in its own server) is done exclusively by means of CMP entity beans. A entity bean may access other entity beans. There are workflow session beans (stateful and stateless) that access the entity beans. All clients see only the workflow session beans (session beans fagade).
Our applicatoin is complex, having more than 80 session beans and more than 25 entity beans (not counting entity beans that exist only to represent relationships among entity beans).
There goes the questions:
1) It seems that entity beans cannot currently be referenced by remote interfaces. We couldn't deploy our application using it. Since we could use only local interfaces fot entity beans, thats what is been done now.
2) There is no CMR supported. Is this true?
3) EJBQL seems to be very limited. In the howto examples there are EJBQL statements that compare two numbers. However, when we tried to use String comparisons, it didn't work. Here is the statement:
"SELECT DISTINCT OBJECT(p) FROM Person p WHERE p.name = ?1"
If I compile, package and deploy the ear applicatin with the above EJBQL statement, OC4J generates an exception when executing the finder method. The exception is:
"java.rmi.NoSuchObjectException: Session has timed out
at com.evermind.server.ejb.StatefulSessionEJBObject.throwPassivisat
ception(StatefulSessionEJBObject.java:188)
at Cad023Remote_StatefulSessionBeanWrapper0.obterPessoasPorParteNom

at java.lang.reflect.Method.invoke(Native Method)
at com.evermind.server.rmi.RMICallHandler.run(RMICallHandler.java:8
at com.evermind.util.ThreadPoolThread.run(ThreadPoolThread.java:64)"
If I remove the where clause, the expection is gone. However, I get all records. ;-)
4) It seems that all EJBQL clauses must be capitalized. Is this true?
FINALY)
Is there a newer OC4J build that could use to get the development going? Do you know where there will be one? Is there any way of contacting the OC4J development team to report bugs?
If you would like, we could discuss it in private e-mail (please use my private mail [email protected]).
Thanks for your attention,
Luis Fernando Soeiro
Hi !! OC4J 9.0.3 developer's preview has most features of EJB 2.0. We are working on updating on our docs and samples for EJB 2.0
Please look at the following URL that has some How Tos on EJB 2.0 features such Local Interfacea, EJB QL, etc : http://otn.oracle.com/tech/java/oc4j/htdocs/oc4j-how-to.html#ejb

Luis Soeiro <mailto:[email protected]> <mailto:[email protected]>Type : Question Date : Apr 11, 2002 15:15 PT Hello
Some colleagues and I are trying to port a large project from JBOSS to OC4J. We used JBOSS 3.0 (beta) in order to evaluate EJB2.0 features and see if we could use it. We already have OC4J in production, but only as a JSP/Servlet container. The next step would be to deploy our EJB application to OC4J.
We have read the material and it is written that OC4J (developers preview) is EJB 2.0 compliant. However, the specific documentation and the examples don't show how to specify OC4J specifc XML files. We absolutely need CMR and Local Interfaces, because we don't have the time required to downgrade our JBoss EJB2.0 application to the EJB 1.1 specification. We have over 80 Session Beans and over 20 Entity Beans.
Is there anybody there that can confirm that OC4J developer's preview is really EJB2.0 compliant? If so, could you send me some pointers to information about OC4J container specifc deployment descriptors? The docs listed at the web site don't have EJB2.0 features listed, nor does the Oracle samples.
Thanks for your attention,
desperately,
Luis Fernando SoeiroHI,
I worked out CMR and EJB-QL with single bean.
Using CMR, it is possible to get one bean reference through other bean, but
When I tried EJB-QL with bean to bean navigation then I run into problem.
