I am trying to use the quartz scheduler that comes with JBoss. I have created a simple job that logs a message every few minutes. Now that I have this working, I want to call a job that requires Hibernate and Java Persistence. When I do this I get errors because the persistence.xml file is not found in META-INF folder. I beleive this is a class path issue. Here is the error I am getting:
12:36:00,034 INFO [Ejb3Configuration] Could not find any META-INF/persistence.xml file in the classpath

Here is my setting the the ejb-jar.xml:
<message-driven>
| <ejb-name>GISBatch</ejb-name>
| <ejb-class>com.idfbins.nexus.batch.ExecuteGISBatch</ejb-class>
| <messaging-type>org.quartz.Job</messaging-type>
| <transaction-type>Container</transaction-type>
| <activation-config>
| <activation-config-property>
| <activation-config-property-name>
| cronTrigger
| </activation-config-property-name>
| <activation-config-property-value>
| <![CDATA[0 */2 * * * ?]]>
| </activation-config-property-value>
| </activation-config-property>
| </activation-config>
| </message-driven>
Here is my JBoss.xml:
<?xml version="1.0" encoding="UTF-8"?>
| <jboss>
| <enterprise-beans>
| <message-driven>
| <ejb-name>QuartzTst2</ejb-name>
| <resource-adapter-name>quartz-ra.rar</resource-adapter-name>
| </message-driven>
| <message-driven>
| <ejb-name>GISBatch</ejb-name>
| <resource-adapter-name>quartz-ra.rar</resource-adapter-name>
| </message-driven>
|
| </enterprise-beans>
| </jboss>
|
Here is the class that gets scheduled. It is located inside and EAR deployed on JBoss:
package com.idfbins.nexus.batch;
|
| import javax.ejb.EJBException;
| import javax.ejb.MessageDrivenContext;
| import javax.jms.Message;
|
| import org.jboss.logging.Logger;
| import org.quartz.JobExecutionContext;
| import org.quartz.JobExecutionException;
|
| public class ExecuteGISBatch {
|
| /**
| * @param args
| */
| /*
| public static void main(String[] args) {
| // TODO Auto-generated method stub
| GISDataBatch batch = new GISDataBatch();
| batch.assignLocationsCoordinates();
| }
| */
|
| private static final Logger log = Logger.getLogger(QuartzTst2.class);
|
| public void execute(JobExecutionContext jobExecutionContext)
| throws JobExecutionException {
| log.info("Executing GIS Batch");
| log.info("class path="+System.getProperty(
| "java.class.path"
| ));
|
| GISDataBatch batch = new GISDataBatch();
| batch.assignLocationsCoordinates();
| }

| throws EJBException {

|

| log.info("GIS Batch job created");
| }

I have read that if I set the Quartz property: useClassLoaderOfInitializer to true then it will use the JBoss class loader and everything should be on the classpath. If this is correct, I just need to know where to update or create the quartz.properties file. If I am incorrect I need to find a way to make sure that when the job is run that everything in my EAR is in the classpath. What is the best way to do this?
