[rules-users] Drools Guvnor and jboss single sign on

2009-12-08 Thread সাহিদ

Hello,

I have couple of web applications other than Guvnor deployed in JBoss.
I use jboss single sign on [1] for authentication. But guvnor does not
seem to be working. I believe there are some issues with JBoss Seam
and JBoss SSO. But is there any work around to integrate JBoss SSO
with Guvnor? Please help.

Thanks in advance,

Re: [rules-users] Human Task Work Item

2009-12-08 Thread Vijay K Pandey

I don't think you can get hold of workItem directly from Task  the only 
reference Task has the workItemId.  May be you can serialize the workItem and 
set to the content of the Task( I don't like it) - and then retrieve it later  
--- else I guess you have to get hold of WorkItemInfo and then workItem..

Also creation of knowledgesession is not process/time consuming so I don't see 
any harm in there

I guess first you have to get hold of the "workitemid" from the task data i.e. 
task.getTaskData().getWorkItemId().

a)   Create a "Command" class which implements GenericCommand
b)   Implement the method "public WorkItem execute(Context context)"
c)   Based on the workitem id ( set this value in your command object - 
constructor/setter) - get hold of the WorkItemInfo object through the entity 
manager  and then its workItem - something like this

StatefulKnowledgeSession ksession = ((KnowledgeCommandContext) 
context).getStatefulKnowledgesession();
if (workItemId==null) {
return null;
}
EntityManager em = (EntityManager) 
ksession.getEnvironment().get(EnvironmentName.ENTITY_MANAGER);
WorkItemInfo workItemInfo = em.find(WorkItemInfo.class, 
workItemId);
if(workItemInfo==null){
return null;
}else{
  return workItemInfo.getWorkItem();
 }

   d) Then call the execute method on the StatefulKnowledgeSession - which 
should execute the above Command object and that returns you the WorkItem 
object.

Re: [rules-users] Multiple packages approach

2009-12-08 Thread Ross H

The other factor to consider is how you do your premium calculations. If
they are mainly in the rules and with many common elements then Greg's
points 1 and 2 apply.

On the other hand if the calculations are mainly in java code or lookups and
your rules coordinate the use of this code then other factors will determine
your choice, particularly the multi product/brand/channel combinations.

The key determining factor in all of this is probably the %commonality
between rules.

Try doing a project clean, and check that eclipse is copying all the drls
into the output folder, by default this is bin. If that's not working you
might need to try and put together a small example that shows the problem
and share that.

They are all source folders in eclipse, so they should be.
