Hi, I am new to Hibernate and Jboss so getting the architecture right here is a little confusing.
This is my problem,
I am getting an unexspected error thrown from my onMessage method in my message driven bean.
As the docs state this will happen for example if the instance failed to open a database connection.
This is what I am doing but through Hibernate.
My onMessage method is trying to open and close a session just at this point.
I'm using JBoss 3.2.5 with Hibernate 2.1.
This is my onMessage method
Code:
public void onMessage(Message message){
try{
ObjectMessage oMessage = (ObjectMessage)message;
MyTestBean bean = (MyTestBean)oMessage.getObject();
System.out.println("Received : "+bean.getMessage());
message.acknowledge();
System.out.println("Trying hiberante connection");
HibernateSession.currentSession();
System.out.println("Got Hibernate Session");
HibernateSession.closeSession();
System.out.println("Clossed Hibernate Session");
//sendReply();
}catch(Exception e){
System.out.println("Error : "+e.getMessage());
}
}
this is my HibernateSession singleton class that will manage the sessions
Code:
package server.j2eeHibernate.components;
import net.sf.hibernate.SessionFactory;
import net.sf.hibernate.Session;
import net.sf.hibernate.HibernateException;
import javax.naming.Context;
import javax.naming.InitialContext;
public class HibernateSession {
private static final SessionFactory sessionFactory;
static{
try{
Context ctx = new InitialContext();
sessionFactory = (SessionFactory)ctx.lookup("java:/HibernateFactory");
}catch(Exception e){
throw new RuntimeException("SessionFactory Error - " + e.getMessage(),e);
}
}
public static final ThreadLocal session = new ThreadLocal();
public static Session currentSession() throws HibernateException{
Session s = (Session)session.get();
if(s==null){
s = sessionFactory.openSession();
session.set(s);
}
return s;
}
public static void closeSession() throws HibernateException{
Session s = (Session)session.get();
session.set(null);
if(s!=null){
s.close();
}
}
}
These are my xml config files for Hibernate and Jboss to talk,
//jboss-service.xml
Code:
<server>
<mbean code="net.sf.hibernate.jmx.HibernateService" name="jboss.jca:service=HibernateFactory,name=HibernateFactory">
<depends>jboss.jca:service=RARDeployer</depends>
<depends>jboss.jca:service=LocalTxCM,name=asademo</depends>
<!-- Make it deploy ONLY after DataSource had been started -->
<attribute name="MapResources">server/j2eeHibernate/deploy/classes/versioning/VModule.hbm.xml</attribute>
<attribute name="JndiName">java:/com/env/HibernateFactory</attribute>
<attribute name="Datasource">java:/asademo</attribute>
<attribute name="Dialect">net.sf.hibernate.dialect.SybaseAnywhereDialect</attribute>
<attribute name="TransactionStrategy">net.sf.hibernate.transaction.JTATransactionFactory</attribute>

<attribute name="UseOuterJoin">false</attribute>
<attribute name="ShowSql">false</attribute>
<attribute name="UserTransactionName">UserTransaction</attribute>
</mbean>
</server>
//hibernate.cfg.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN" "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
<hibernate-configuration>
<session-factory>

<property name="connection.url">jdbc:sybase:Tds:localhost:2638?ServiceName=asademo</property>
<property name="dialect">net.sf.hibernate.dialect.SybaseAnywhereDialect</property>
<property name="connection.username">DBA</property>
<property name="connection.password">SQL</property>
<mapping resource="server\j2eeHibernate\deploy\classes\versioning\VModule.hbm.xml"/>
</session-factory>
</hibernate-configuration>
//and hibernatesybase-ds.xml
Code:
<datasources>
<local-tx-datasource>
<jndi-name>HibernateFactory</jndi-name>
<connection-url>jdbc:sybase:Tds://localhost:2638/asademo</connection-url>
<driver-class>com.sybase.jdbc2.jdbc.SybDriver</driver-class>
<user-name>DBA</user-name>
<password>SQL</password>
</local-tx-datasource>
</datasources>
both jboss-service.xml and hibernate.cfg.xml reside in the root of my deployed jar file.
hibernatesybase-ds.xml is sitting in my jboss/server/default/deploy.
this is my stack trace,
