[Installation, Configuration & DEPLOYMENT] - Multiple EAR deployment not working as documented (at all !)
by paulsmith22221
I have 2 EARs that I wish to deploy in the same JBoss configuration. The EARs have identical contents except for the conf/log4j.xml file, the MySQL datasource file, and the META-INF/jboss-app.xml file. One of the files in each of the EARs is a JAR file (config.jar) containing POJOs and EJBs. config.jar is in the root level of the EARs.
When I deploy the EARs I get the error:
anonymous wrote :
| --- MBeans waiting for other MBeans ---
| ObjectName: jboss.j2ee:module=config.jar,uid=31702491,service=EjbModule
| State: FAILED
| Reason: javax.management.InstanceAlreadyExistsException: jboss.j2ee:jndiName=ejb/CustBean,service=EJB already registered.
|
This article http://www.jboss.org/community/docs/DOC-9288 and others I have found led me to make the changes:
| myear1.ear: META-INF/jboss-app.xml
| <jboss-app>
| <loader-repository>com.mycompany:loader=myear1.ear</loader-repository>
| </jboss-app>
|
| myear2.ear: META-INF/jboss-app.xml
| <jboss-app>
| <loader-repository>com.mycompany:loader=myear2.ear</loader-repository>
| </jboss-app>
|
Section 2.2.2.4.2 of the documentation found here http://docs.jboss.org/jbossas/jboss4guide/r1/html/ch2.chapter.html confirms what I have done is correct.
In default/deploy, my ear-deployer.xml has the contents:
| <server>
| <mbean code="org.jboss.deployment.EARDeployer"
| name="jboss.j2ee:service=EARDeployer">
| <attribute name="Isolated">true</attribute>
| <attribute name="CallByValue">false</attribute>
| </mbean>
| </server>
|
The EARs have identical META-INF/application.xml files with contents:
| <module>
| <web>
| <web-uri>eartest_w.war</web-uri>
| <context-root>test_root_ctx</context-root>
| </web>
| </module>
|
| <module>
| <java>config.jar</java>
| </module>
|
I want only one code base, and so having different JNDI names for my beans in each copy of config.jar is not something I want to do. The articles I have read suggest that what I want to do is possible, but I am clearly missing something. Any help therefore greatly appreciated!
Thanks,
Paul
