[jBPM Users] - How can I query run my own HQL in jBPM 4.x?

by vchira

I have searched the forums buit i was unable to find a solution to my problem. I am trying to run my own hql query using the hibernate session that jBPM is using. how can i do that? is there a way to do something like this using jBPM API? if I could do that i could also search the task instances for a specific task that has some value saved in some variable.

[JBoss Messaging Users] - Mutable Objects inside ObjectMessage and rollback behaviour.

by dcausse

Hi, with JBM shipped with JBossAS 5.1.0, i suspect that ObjectMessage body instances are cached. In a transaction I modify my object issued from ObjectMessage.getObject(), then something goes wrong and I do rollback on the JMS session. When the broker send the message a second time I get the same instance as the first failed receive with modifications made on my object in the previous failed transaction, It is not what I expect. So my question is : is this normal behaviour? Can I disable this cache and have everything rollbacked and my object deserialized again? Thank you for your help.

[EJB 3.0 Users] - How to load classes dynamically in EJB3 on JBoss 4.2.2 at Ru

by samuelpaulc

Hi All, My application is a SWT application on the client side and an EJB3 on JBoss 4.2.2 on the server side. Users(from client) can upload jars containing classes that are copied onto the JBoss server machine to a known directory. The classes within the newly uploaded jars have to be loaded,instantiated and a known method has to be called on them. We have enforced upon the user to implement our base interfaces in their classes so that we can call any new jars that are uploaded at runtime without shutting down and bringing up JBoss. I am getting a NullPointerException when I try to load the class dynamically(using URLClassLoader) We have tried using URLClassLoader but the loaded class is not visible at runtime. Also tried to load class using UnifiedClassLoader3 but am not sure I did the right way. Please suggest the best possible way to do this ASAP.

[Installation, Configuration & Deployment] - Multiple JBoss instances vs. one "big" JBoss with different

by icordoba

hello, I start this thread to get opinions on which is the best approach when needing to deploy multiple different applications in the same server. I've been using JBoss for years starting with version 3. During this time I've used a couple of JBoss instances with scope class loading, even though docs state that disabling unified class loading and enabling marshaning (CallByValue?) is CPU consuming. I am migrating now to JBoss 5.1 and have decided to test keeping unified class loading and starting multiple JBoss'es in differennt localhost IPs. (I cannot deploy different applications in the same instance as I have many version conflicts. I use multiple versions of my own EJB3 component library) These JBoss will need less memory than the previous one and only JBoss. Of course, they are faster now. is this approach right? I use MacOS and its Java VM, while not specially fast, it is suppoused to handle memory sharing between different java instances. Maybe there is a different approach for deploying different apps in the same server... as far as I know there is no way to enable isolated class loading without enabling "CallByValue"... is there? Thanks for any advice/experiences.

[jBPM Users] - JBPM4: How to find leaving transitions of an execution

by mbelow

Hello, I'm quite new to JBM4... I would like to fetch a list of all transitions leaving the current activity of an execution. I thought that this would actually be a quite common thing to do, but I was only able to archive this with an ugly cast (from Execution to ExecutionImpl). Is there a cleaner way of doing this using the API?

[JBoss Messaging Users] - Re: 1.4.x Topic Subscriber and TTL'ed Messages

by chacs

In a clustered environment, the subscriptions are also split into sub-subscriptions at each cluster. If we wish to implement the nightly cron to clear the expired messages (using CLIENT_ACKNOWLEDGE and rollback), we must be able to obtain the connection manager for each cluster to clear it's local expired messages. The inability to connect to a specific cluster means this cannot be a viable solution.
