[Persistence, JBoss/CMP, Hibernate, Database] - jboss 4.2 Hibernate 3.2 entity mapping problem
by cgrahamatip
I am trying to get a test jsf application to work on the standard jboss 4.2.0 AS server. I am using eclipse as the IDE. I set the build path in my eclipse project to point to jboss/default/lib jar files for hibernate and other required jars.
when I deployed the application everythings works as it should until I make a call from a backing bean to query or load a hibernate class. I get the following error: "org.hibernate.MappingException: Unknown entity: com.ipi.jsfapp.model.People".
Any information would be greatly appreciated..
The configuration snippets are:

[JBoss Seam] - Re: PAGE context and Ajax4JSF
by jazir1979
Hi Gavin,
Thanks for the reply.
"gavin.king(a)jboss.com" wrote : anonymous wrote : the serialized page state is not available when Ajax4JSF goes through the JSF lifecycle to process the validations
|
| I'm sure that's not correct. Ajax4JSF does resubmit the serialized state back to the server.
|
I'd have thought so too, but I read something on the forums which led me to believe this was the problem (can't find the link now). Perhaps the behaviour I'm seeing is actually to do with my @Factory/@DataModel usage.
Here's what's happening...
| @DataModel(scope = ScopeType.PAGE)
| private List<Batch> batchList;
|
| @Factory("batchList")
| public void search() { ... }
|
Now, every time focus leaves an input box that has Ajax4JSF validation on it, the search() method gets called on the server. I assumed this was because the Ajax4JSF request does not have the page scoped "batchList" available, so the @Factory gets called. What do you think?
"gavin.king(a)jboss.com" wrote :
| anonymous wrote : i wanted the data model to refresh on each request.
|
| Then what you need to do is re-render the whole f:view. If you don't re-render the ViewRoot, then the PAGE scope attributes won't be updated on the client side.
|
| If you use reRender="theViewRootId", everything should work fine.
|
Those requests aren't PPR/ajax.. but thanks for that tip because if I solve the above a4jsf validation problem, I will probably change this later on and I would have just reRender'ed the data table, not the whole view.
cheers,
Daniel.

[JBoss jBPM] - Getting a list of the process variables in a process instanc
by lachelt
>From outside of a process instance I want to get visibility into the current state of a process instance (e.g. what are its process variables and their values). For some context? I am showing a list of the process instances, but want to give the client more than just the instance id, process name, start time, end time, etc. I want to give more info that identifies this process instance (to a user) ? which would come from variables in the process instance.
I found that I can get the root token for a process instance, and then construct an ExecutionContext from that which lets me get a variable. This seems sort of overkill. I don?t want to do execution at this point? I just want to see into the process instance. Is this the only/recommended way to do what I want?
Also, is it possible to get a list of the Process Variables in the process instance? I?ve only found the ExecutionContext.getVariable() method ? for which I need to know the name of a specific variable I am interested in.
Thanks,
-Jon
