Coherence exception in JPA

Hi,
I am using open jpa for persistence in my clustered weblogic server envirnment. I am using coherence for locking support and distributed cache mgmt.
But while creating entity manager from the Persistence.xml file, i am getting an error, for which the base exception is thrown from the tangosol classes.
Here is a complete stack trace of the error.

Exception in JPA (NoClassDefFoundError: org/hibernate/AnnotationException)

Hi,
I´m having a serious problem when using JPA. I´m using Weblogic Server 10 and developing in Weblogic Workshop Studio. When I start the WLS in Workshop, all works fine, but when I use the "publish" over my WLS Server in Workshop because I change any class in the project (and I need to republish the project to send the changed class to WLS), the following error is reported when I try to use the JPA:
Caused by: javax.ejb.EJBTransactionRolledbackException: EJB Exception: : java.lang.NoClassDefFoundError: org/hibernate/AnnotationException
at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:353)

Why the AnnotationException class is no more found after a publish in a started Weblogic Server ?
Thanks in advance,
Sergio Stateri Jr.

Sergio,
there are at least three implementation for JPA available: OpenJPA, TopLink, and Hibernate. The first two are or can easily installed in WLS. If you intend to use Hibernate as the persistence provider you should ensure that all libraries are in the class path of your application.

How To Handle SQL Exceptions in JPA

Hi,
we are working on toplink JPA. My use case is I have an emp table with columns as "empid" , "emp name" , "job" with "empid" as primary Key. Here I'm creating a record in the Database by using a jspx page. Here My problem is when I'm entering a duplicate value for the empid I'm getting "ORA-00001: unique constraint (constraint_name) violated" . I'm able to catch the exception in the jspx backing bean where I'm calling the JPA insert method, But i could not catch the exception in the sessionEJB Bean. Is there any way to catch such exception in the sessionEJB.
could anyone help me out.
Thanks in Advance.
regards,
PrapanSol

You should be able to call flush on your EntityManager in your SessionBean to trigger the exception.
Note that the transaction will still be rolled back even if you catch this exception.

Coherence exception - This service timed-out due to unanswered handshake request

Hi,
We are getting weird errors in production with below exception - Oracle Coherence GE 3.5.1/461 <Error> (thread=DistributedCache, member=2): validatePolls: This service timed-out due to unanswered handshake request. Manual intervention is required to stop the members that have not responded to this Poll.
To give little back ground on the issue, we had multicast coherence setup in production with 3 servers are in coherence cluster.   We are using JBoss as our application server. Coherence version currently using in production is : 3.7.1.0b27797. Our applications are running in 2 data centers and interestingly this issue is occurring in only one data center. So not sure weather it is coherence issue or environmental issue.
If this issue occurs in one or two servers then they are able to recover after some time. But if is happens on all 3 servers, then all 3 servers are dead and causing production outage.
We have captured the thread dump from production servers when this issue occured and noticed all application threads are hanging at WAITING state with below thread stack trace

               return bcsNe;
     }The relation between BcsNe and BcsPort is one to many with BcsNe as the parent and BcsPort as the child.
Junit invocation is as follows
//@testMethod
     tx.begin();
     for (BcsPort port : bcsPortList) {      // All the ports have the same ne
     neBean.*updateNE*(port.getBcsNe());//Throwing the Exception in question
   tx.commit();The Junit runs well if the ne values are different,
All comments suggestion are welcome..
Thanks

merge can only be called for an entity that comes out of the entity manager. If you jUnit test creates the entity instance without first getting it it from the entity manager, this latter cannot "merge" it, merely "create" it. I'm not talking about whether the entity's data exist in the DB, really about which entity manager you get the entity from.

Using EclipseLink or JPA with Oracle Coherence as shared cache

Hi,
I expect to use EclipseLink with Oracle Coherence as shared cache, mainly with/for Entity Caching.
* JPA)
For JPA queries, is the JPA semantics fully preserved when using Oracle Coherence ?
* Non-JPA)
Are the non-JPA API taking also advantage from Oracle Coherence ?
For these non-JPA queries, is the semantics fully preserved when using Oracle Coherence ?
Regards,
Dominique
PS: I hope this is the right forum to ask my questions.
Otherwise, could you tell me what is the right forum ?
Thanks.

Yes, JPA semantics are fully preserved when using TopLink-Grid to cache entities within Coherence.
Yes, the native EclipseLink APIs can also take advantage of TopLink-Grid and Coherence.
I am not sure what you mean by "For these non-JPA queries, is the semantics fully preserved when using Oracle Coherence ?" Perhaps you can provide an example of what you are looking for?

Running Weblogic 10.3.3.0 with Coherence 3.5.

There are multiple ways to configure WebLogic with Coherence as described in the Active Cache guide but to define EAR scoped caches you need to deploy the jars to WebLogic as shared libraries, not put them on the server classpath. You can define shared libraries using the WLS Admin Console or you from the command line. Coherence and Active Cache jars deployment is described here: http://download.oracle.com/docs/cd/E21764_01/web.1111/e16517/coh_wls.htm#BABHAHJG and TopLink Grid here: http://download.oracle.com/docs/cd/E21764_01/web.1111/e16517/package_wls.htm#BABJCGIG

Coherence gives error just after starting up

Hi,
Whenever I start up my app, after the app has started I get the below coherence exception. Any idea why this might be happening?
Oracle Coherence GE 3.5.1/461 <D5> (thread=PacketSpeaker, member=1): Attempt to refresh sockets: [UnicastUdpSocket{State=STATE_OPEN, address:port=$IPADDR:8088}, TcpSocketAccepter{State=STATE_OPEN, ServerSocket=$IPADDR:8088}] caused by UnicastUdpSocket{State=STATE_OPEN, address:port=$IPADDR:8088}; exception java.io.IOException: Invalid argument

Hi user1945969,
Can you provide some additional information:
- your Coherence operational configuration file
- any Coherence system properties you are specifying
- full Coherence startup logs, please specify log level 9 see http://coherence.oracle.com/display/COH35UG/logging-config#logging-config-level
- OS vendor/version
- JVM vendor/version
thanks,
Mark

JPA and database error handling

Can anyone point me towards any information or discussions on methods of handling database initiated exceptions with JPA? Specifically, I'm trying to handle common data exceptions, like primary/foreign key violations etc., so I don't have to duplicate that level of data integrity checking in my business logic.
It seems I can only get hold of a RollbackException if something goes wrong. Ok, I can get into the underlying cause easily enough, but then I'm straight into implementation specific stuff (in my case, Hibernate exceptions). Are there any good techniques/patterns to reduce this dependency to an absolute minimum?

In this situation I created @Id for one of the columns or created @IdClass from all view fields.

Problem using TopLink Grid on WebLogic

I encountered an error using TopLink Grid with WebLogic.
I have a servlet that persists an object through TopLink Grid, and then try to retrieve an object. It has the following setup:
JPA 2.0
TopLink 11.1.1.4.0
Coherence 3.6.0.4 (bundled with WebLogic)
WebLogic Server 10.3.4
Cache config: Grid Entity
Method of obtaining EntityManager: Injection of @PersistenceContext
Transaction Management: JTA
I put coherence-cache-config.xml and tangosol-coherence-override.xml in /APP-INF/classes in my EAR file.
I did not use active-cache.jar in my servlet. After the WebLogic server is started, the Coherence cache client is to be launched when the persist operation is called.
However, found that the insertion fails with error. Only when em.find() is called could the Coherence cache client be launched properly. I find it very strange because toplink grid complains about missing coherence-cache-config.xml when it tries to insert, but is perfectly ok when it tries to do an em.find().
Has anybody encountered the same issue before?
The log is: (the lines starting with #### are output by the servlet)
#### Inserting new dept

It seems Coherence is unable to load the config files using the application class loader. You could try placing the config files in a location that gives them the same visibility as your PersistenceUnit.

Failed to load operational configuration

Dear support,
I have an application which uses toplink grid. However, once I get the data from DB and would like to cache the data, it throws exception.
Do you have any idea of the following stack trace? Seems that it is related to failure to load the configuration.

It could be one of a few things; Coherence is validating the XML file against its schema so either...
1. You have a custom tangosol-coherence.xml file that is not valid
2. You have incompatible XML jars in your classpath - we had this problem with an old version of Xerces that was in our classpath.

Initially this application was giving me absolute path related errors.But when I made changes to applicationContext.xml as follows,giviing absolute path for Hibernate mapping files
<property name="mappingDirectoryLocations">
     <list>
     *<value>file:D:\saas-mappings</value>*
     </list>
</property>
I have extrached all the *.hbm.xml file to above location that is D:\saas-mappings.But now the application is giving me above mentioned error.The error says that it is related to Named queries.I am pasting the contents of a sample *.hbm.xml file having named query as a sample

Hi,
For a tutorial with source on how to create and deploy a simple quickstart JEE5 JPA enterprise 3-tier application on your Oracle WebLogic 10.3 server - see the following example that uses the EclipseLink JPA provider. You should be able to transition all of your mapping information (the @ManyToOne and table/column overrides and named queries for example) using either JPA via entity annotations or native extensions if you do not want to implement EJB3.
see...
http://wiki.eclipse.org/EclipseLink/Examples/JPA/WebLogic_Web_Tutorial
We also have a similar version for Tomcat 6 except the JPA entity beans run outside a container-managed JTA transaction on the web container - for reference.

Error while deploying a .war file

Hi,
I have a one Servlet class, which references two more classes for database
connection. After creating a .war file, I am trying to deploy it on iAS, and I
get the following error:
Failed to deploy web application "MBSServlet". Jar file: /var/tmp/jar61304.tmp
is missing its standard xml descriptor located at WEB-INF/web.xml
I don't know anything about /var/tmp/jar61304.tmp, I don't know where is it picking it up from. And my web.xml is as follows:
<?xml version="1.0" standalone='yes'?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN" " " target="_new">http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">
