[JBoss jBPM] - History Functions
by gosub33
Hey all. I have been looking for a few days now at documentation and can't seem to be able to do something I thought would be quite simple.
Here is the business problem: my client is interested in tracking who made what decision and when. They also want to incorporate the diplay of that history into the site. For the purposes of discussion, each decision is 'userstamped' (which means their username and datetime is stamped).
Here is an example, to illustrate the problem:
-Order comes in from client.
-Admin clerk who looks at it first generates a userstamp
-If there is no product in the warehouse, the clerk creates an order. A userstamp is captured about who ordered it (and later who approved the order).
-Email is sent to the client that it has been back-ordered, the person sending the email has a userstamp captured
- etc.
- Later a Manager comes by and reviews the order. They see a page that shows the history of the order as well as the userstamps (who, when).
I can easily see how to implement something like this using JBPM, but I really don't want to re-invent the wheel. Is this functionality already built into JBPM? If so, how can it be accessed?

[EJB/JBoss] - Finder exception after upgrade from 4.0.5 to 4.2.2
by aazaroff
I did look in the archives and saw a previous reference to this but it was logged against a 4.0.x series and had appeared to be resolved. It was in reference to the query generator creating malformed queries. I want to post this just to make sure the problem has not cropped back up.
We are in the process of upgrading from 4.0.5 to 4.2.2 and have run into an issue. We have basically just copied all of our deployed code and libraries into the new install as we did for the last 3 or 4 upgrades (running since 3.2.1) we have done. This time however none of my EJB2 entity beans will work. All of the ones I have tested so far fail with the following error:
[org.jboss.ejb.plugins.cmp.jdbc.JDBCFindByPrimaryKeyQuery.XmlfeedrequestsBean#findByPrimaryKey] Find failed
This is now deployed into a stock 4.2.2 jboss install. We are running on the exact same physical piece of hardware that the previous version was. In fact everything works from the previous installation when we fire it back up in place of the new install. Same database backend, same everything except the jboss install.
Note:
There are no issues with any of the EJB2 session beans or any of the EJB3 beans (session or entity) we have deployed only the EJB2 entity beans.
I can provide any code/deployment descriptors necessary.
Thanks
Andre

[Clustering/JBoss] - Load balancing and dev environment
by maralcbr
Hi,
I have searched the forums and the JBoss Clustering documentation for a while, but could not find the information I needed.
We intend to use two servers in our partition and for that, we intend to keep each client on the same server it first connected.
1) For that, I intend to use the org.jboss.ha.framework.interfaces.FirstAvailableIdenticalAllProxies load balancing configuration for JNDI HA and the EJBs.
There is really no centralized way to do this configuration? Besides JNDI HA each EJB should be configurated individually?
2) For the development environment, the idea, for not having to change the descriptors/annotations all the time, would be the load a single JBoss server with the clustering turned on?
Thanks in advance for any help.
Regards,
Marcelo Alcantara
