Hi Denys.

Sorry for not getting back faster. What you sent me was incomplete. I was missing some source and dependencies, so I wasn't able to run it up.

Anyway, sounds like you have some things to try out there from Daniel and Kevin's posts.

The suggestion here is to use use classloading isolation. You can do this by isolating the .esb archive as described here : http://www.jboss.org/community/docs/DOC-10339

Daniel,
I'm traing this but I have exception.

Here is my deployment.xml

kconner Oct 23, 2008 7:22 AM (in response to denix)

The isolation is unlikely to help as the Spring classes are not covered by the isolated classloader. The leak will still occur.

We need to take a look at the way in which we are integrating with spring and make sure that all resources are tidied up correctly on undeploy.

beve Oct 23, 2008 7:22 AM (in response to denix)

Ok, the scoping looks fine. I'd really need to try this as I cannot reproduce the error.
Could you modify that you sent Tom so that I can run this and try to find out what is happening? Tom mentioned that he could not get it to run in a previous post that is way I'm asking for this.

Thanks,

/Daniel

okey, I will prepare small project which docs which will show all bugs and then send it all to you

Because of lack of time I decided to write all our project characteristics:
Spring version - 2.5.5
Hibernate version - 3.2.4.sp1

deployment.xml

<?xml version="1.0" encoding="UTF-8"?>
<jbossesb-deployment>
 <depends>jboss.esb:deployment=spring.esb</depends>
</jbossesb-deployment>

jboss-esb.xml

<?xml version = "1.0" encoding = "UTF-8"?>

<schedule-provider name="scheduler">
<simple-schedule scheduleid="xServiceScheduler"
frequency="180" />
</schedule-provider>

<scheduled-listener
name="xprocess_scheduled_listener"
scheduleidref="xServiceScheduler"
event-processor="dse.x.esb.MsgComposer" />

XActionProcessor.java



package ds.x.esb;

import java.util.List;
import java.util.Map;

import org.apache.log4j.Logger;
import org.jboss.soa.esb.actions.AbstractSpringAction;
import org.jboss.soa.esb.actions.ActionLifecycleException;
import org.jboss.soa.esb.helpers.ConfigTree;
import org.jboss.soa.esb.message.Message;
import org.springframework.beans.BeansException;

import ds.x.Netting;
import ds.x.Util;
import ds.persistence.entity.CashFlow;

/**
 * ESB netting service.
 */
public class XActionProcessor extends AbstractSpringAction {

 private static final Logger logger = Logger
 .getLogger(NettingActionProcessor.class);
 private OrdersDAO ordersDAO;

 public XActionProcessor(ConfigTree _config) {
 super(_config);
 }

 /**
 * Invoked by ESB runtime
 */
 @Override
 public void initialise() throws ActionLifecycleException {
 super.initialise();

 try {
 ordersDAO = (OrdersDAO getBeanFactory().getBean("ordersDAO");
 } catch (BeansException bee) {
 logger.error(bee);
 throw new ActionLifecycleException(bee);
 }
 }

 public Message xProcess(Message msg) throws Exception {
 ordersDAO.getAll(); //after hot re-deploying it will not return all orders
 List<Order> orders = ordersDAO.getOrdersByStatus("Completed"); //if getOrdersByStatus method uses HQL after hot re-deploying it will throw an exception that couldn't find mapping for class Order (we map using annotations)

 return msg;
 }

}

also see my comments in method xProcess for more error-prone behaviour.

All other bugs you may reproduce with this code. applicationContext-dao.xml and all Spring beans are packed in separate jar which included to ESB archive.

Hi,

I've created a quickstart that is supposed to simulate your application. It uses spring and hibernate and the AbstractSpringAction mimics the code you posted.

But I'm not able to reproduce this issue. If you like I can send the quickstart to you and perhaps you can see if there is something that different that I've missed?

If you send me an email I'll reply and send you the quickstart.

Regards,

/Daniel

Hi Denys,

Thanks for the update/new example that you sent!

I've looked into this and this is just an update on what I've got so far.
The exception that you posted (not the original one):

This was caused by the the spring jar being included in your .esb archive. This jar should only reside in the spring.esb archive.

I'll look into the other issue(s).

Regards,

/Daniel

23. Re: Why JBoss ESB doesn't delete services from registry when

denix Oct 29, 2008 12:05 AM (in response to denix)

Thanks to Daniel currently I cannot reproduce all hot deployment issues. Also services successfully unregister from registry when overwriting.

In my case I removed hibernate & spring jars from my .esb file, i.e. if you use maven just use provide

and copied removed jars to my servers /lib directory.

These are the jars have been added in my case:
persistence-api-1.0.jar
hibernate-annotations-3.2.1.ga.jar
hibernate-3.2.4.sp1.jar
ehcache-1.6.0-beta1.jar

And removed old one:
hibernate3.jar
hibernate-annotations.jar

Also I updated spring.esb with my own spring.jar version.

It's works!
