[jboss-user] [JBoss Web Services Users] - Re: Cannot find service endpoint target
Salut mecs, the problem hints to an inavailable ressource on the session bean, like a delayed of unavailable datasource.You shold check the server.log for any kind of ressource problems. In our case, our web-services suddently ran into the same problem,. throwing the same exception. We are using an Oracle-DB for to persist our data. Sombody changed the OracleDialect to OracleDialect or another one finally we hat the problems with our webservice. Some week later i noticed error messages (only one line) like this one: server.log.2009-10-02:2009-10-02 11:28:36,575 INFO [org.hibernate.dialect.Dialect] Using dialect: org.hibernate.dialect.Oracle10gDialect server.log.2009-10-02:2009-10-02 11:39:37,602 INFO [org.hibernate.dialect.Dialect] Using dialect: org.hibernate.dialect.OracleDialect server.log.2009-10-02:2009-10-02 11:39:37,602 WARN [org.hibernate.dialect.Oracle9Dialect] The Oracle9Dialect dialect has been deprecated; use either Oracle9iDialect or Oracle10gDialect instead Despite the fact, that this are only warnings, i guess, i found that smoking gun. Assumption: The error/warning condition slowed down the session bean, causing the WS unsuccessfully searching for a session bean, that has not been started. I switched to the Oracle10gDialect and the problem disappeared!

[jboss-user] [JCA/JBoss] - Re: JCA Problem: java.lang.IllegalStateException: Trying to
Salut mc's, the solution is quite simple. The (logical) close operation, that issues a closeSend of the ConnectionEvent class has to attach the connection handle to the ConnectionEvent, before broadcasting this event. so: ce = new ConnectionEvent(this, ConnectionEvent.CONNECTION_CLOSED) ; (new) ce.setConnectionHandle(connection) ; does help me in the closeHandle method.

Salut Peter, > Why are you using 4.2.1? The latest 4.2 version is 4.2.3 and there > is a download available for 4.2.3 that specifically works with JDK6. The 4.2.1 Version looks like the professional version shipped by Jboss. One of our productive systems does run on a 4.2.1. I assumed, that this one is the most recent one shipped as rpm pakages.

I located the problem in the nested class/method: org.jboss.resource.connectionmanager.NoTxConnectionManager.NoTxConnectionManager/connectionClosed ce.getConnectionHandle()); } The ce.getConnectionHandle() expression returns null, that seems to cause the problem. Therefore i think that i forgot to assign a connectionHandle in my ManagedConnection, cause ce referes to ce = new ConnectionEvent(this, ConnectionEvent.CONNECTION_CLOSED) ; where this referes to my managed connection and ce Event was created in the managedConnection method closeHandle.

[jboss-user] [Installation, Configuration & DEPLOYMENT] - JBoss 4.2 and JAVA6, compatibility matrix available
Hy there, i have the problem, we already started our development with JAVA6 using JBoss4.2.x. Yes, i know that Java6 is not officially supported, but the project manager staff decided to use JAVA6. Since JBoss5.x is delivered as a commercial product (supported by Redhat/JBoss), we have to go with JBoss4.2.x Running JAVA6 (on Linux) with JBoss issued some problems on the free JBoss 4.2.x version, that have been solved. Anyway, when i try to deploy my JBoss-ear file on the commercial JBoss server 4.2.1 running JAVA6. The deployment runs without any problem, the Web-GUI does run without any problems, but when i try to access the Web-Service, some exceptions happend. Seeking through the forum tells me, that i am using a wrong JAVA version. Great, but which one i should use ??? Is the a matrix of cooperating JBoss/JAVA Versions availiabe ??

[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: JBOSSAS Install problem - Do I have to use Sun Java?
Salut,
you are using a wrong JRE, coming from GNU-java (also known
als gcj). Try to install a SUN-JDK with via rpm and make sure, that
the run.sh will find firstly the original Sun-JAVA.
> Failed to boot JBoss:
> .. ClassLoader{urls=[], > parent=gnu.gcj.runtime.SystemClassLoader
GCJ is not exactly the same like SUN-JDK!

[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: Deployment of a J2EE1.3 application fails on JBoss4.2.2
Salut, that was my fault. In jboss.xml deployment descriptor i have overseen, that assigned in a stateful session bean the following standard setting: Standard Stateless Sessionbean That has in turn no instance-cache assignment in the default container definition. The good this is, that a started to understand the cool architecture of jboss.

[jboss-user] [Installation, Configuration & DEPLOYMENT] - Re: Deployment of a J2EE1.3 application fails on JBoss4.2.2
Salut mecs, in the meantime i switched to JBoss 4.2.3 but the problem is still there. From my point of view there are exaclty 2 choice for an explanation of this problem: 1) I misunterstood something and overseen some configurations in jboss.xml. The following posting on the JAVA greenhorn ranch shows a similar problem. But for any reason, this behaviour was clear to the author (but not me;) Can anybody explain me, what he talks about? http://www.coderanch.com/t/89576/JBoss/Missing-invalid-instance-cache-error 2) There may be a problem with the deployment for JEE-1.3/1.4 ear's on a JEE-5 Application server or some settings to be done, when you want to run that old application on a novel app server.

[jboss-user] [Installation, Configuration & DEPLOYMENT] - Deployment of a J2EE1.3 application fails on JBoss4.2.2
Salut, i have successfully set up a JEE1.4 environment for to test and run my applications using EJB3. Fine! Some days ago i started a migration project, where an old JEE Application has to move from an Oracle-App-Server to JBoss. So i created a new development-context using Eclipse&Jboss-Tools transfered also the ole JDevelopper to Eclipse. The migration is finished, instread of the oracle-descriptor now there is jboss.xml file doing the job. EAR-Build does create a app.ear that i am trying to deploy on my JBoss 4.2.2 (under Linux, with JAVA 1.6), but i do receive the following exception: 11:56:32,447 WARN [ServiceController] Problem creating service jboss.j2ee:service=EjbModule,module=myAppEJB.jar org.jboss.deployment.DeploymentException: Missing or invalid Instance Cache (in jboss.xml or standardjboss.xml); - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: ) at org.jboss.ejb.EjbModule.createInstanceCache(EjbModule.java:1234) at org.jboss.ejb.EjbModule.createStatefulSessionContainer(EjbModule.java:646) at org.jboss.ejb.EjbModule.createContainer(EjbModule.java:579) at org.jboss.ejb.EjbModule.createService(EjbModule.java:342) The exception seems to occur in the context of a stateful session bean. Thats right, my application has a couple of stateless and stateful session beans, that habe been configured on both descriptor file. Does the error indicate, that the application has problems to persists the data of a statefull session bean ?? Some postings on the web inidicate, that i do have to do some in my jboss.xml, but i do not know how ? Oh, there is another thing i should tell you. I do have 2 datasources, one of them is linked to a read-only oracle-access. When i worked with EJB3 i learned to map persistenc-issues in my persistence.xml to prevetent ambiguous object mapping, but i do not have any persistence.xml in my EJB2.x !!! Thank you in advance for any help!
