[Installation, Configuration & DEPLOYMENT] - EAR deployment with isolated hibernate classes on JBoss 4.2.
by michael.degols
Hi everybody,
I'm trying to deploy an EAR with a new version of hibernate and I'm encountering some problems with class loading (I've read the articles on the wiki but it didn't help).
I've installed a fresh version of JBoss 4.2.3.GA.
ear-deployer is configured with default values (isolated = false, callByValue = false, javaee5lib=true).
I deploy an EAR with isolated class loading with following configuration:
My jboss-app file
| <jboss-app>
| <loader-repository>
| com.example:loader=example-loader
| <loader-repository-config>
| java2ParentDelegation=false
| </loader-repository-config>
| </loader-repository>
| </jboss-app>
|
I've a lib directory with following jars:
- hibernate-entitymanager-3.3.1.ga.jar
- hibernate-annotations-3.3.0.ga.jar
- hibernate-common-annotations-3.0.0.GA.jar
- hibernate-3.2.4.sp1.jar
- hibernate-validator-3.0.0.GA.jar
- ejb3-persistence-1.0.1.GA.jar
- jasperreports.jar
- drools-compiler.jar
- drools-core.jar
When I deploy my app, I've a ClassCastException for HibernatePersistence because the entitymanager jar is loaded twice: once from the default lib of jboss and once from the ear lib. How is it possible with my jboss-app configured with isolated class loading and no parent delegation ?

It looks like the ejb3 deployer requires the loading of jboss-ejb3.jar located in server\default\deploy\ejb3.deployer which then requires the loading of some dependencies like hibernate-entitymanager from the jboss default lib. Only after my own hibernate-entitymanager is loaded resulting in a ClassCastException.
Can somebody explain me what I'm missing here and how I can solve this?
Thanks a lot,
Michael

[Clustering/JBoss] - Re: Invocation of startSingleton()
by _Adam_
Thanks for quick response.
Well, then I suppose I must have some mistake in my configuration files.
Info:
Version: JBOSS 5.0.0 GA
My singleton class:
public class StartupService2 implements StartupService2MBean {
|
| Logger log = Logger.getLogger(StartupService2.class);
| private boolean isMasterNode;
|
| public String getName() {
| return "com.xitee.cfd.be:service=StartupService";
| }
|
| public boolean isMasterNode() {
| return isMasterNode;
| }
|
| public void startSingleton() {
| isMasterNode = true;
| log.info("starting testing-singleton");
| }
|
| public void stopSingleton() {
| isMasterNode = false;
| log.info("stopping testing-singleton");
| }
| }
My MBean interface:
public interface StartupService2MBean {
|
| public void startSingleton();
|
| public void stopSingleton();
|
| public boolean isMasterNode();
| }
My jboss-service.xml:
<server>
| <mbean code="com.xitee.cfd.be2.StartupService2"
| name="StartupTestingCFD2">
| </mbean>
|
| <mbean code="org.jboss.ha.singleton.HASingletonController"
| name="HASingletonController">
| <depends optional-attribute-name="ClusterPartition"
| proxy-type="attribute">jboss:service=${jboss.partition.name:DefaultPartition}</depends>
|
| <attribute name="TargetName">StartupTestingCFD2</attribute>
| <attribute name="TargetStartMethod">startSingleton</attribute>
| <attribute name="TargetStopMethod">stopSingleton</attribute>
| </mbean>
|
| </server>
After deploying the application (into deploy directory) I would expect "starting testing-singleton" string to appear in the server.log file, however this does not happen.
Could you please give me any startup hint, how to solve this? Do you need some more information from my side?
Adam
