[JBoss jBPM] - Re: Fetching Task Variable Instances (Early Loading)
by bradsdavis
Yeah, my suggestion here is the following.
First, I dont think this is as efficient as it should be. However, this is my suggestion at the most efficient result.
Create a DTO that includes the values you want in the grid. Then do a HQL query to fetch the task instance. The key is to make the variable local to the task instance so that it can be pulled in a eager fashion.
So, when you create your task, just add a controller that copies the value from the process instance to the task. That is equivalent to creating a variable locally on the task instance.
So, then you need to fetch the variable eagerly.
| "select task from org.jbpm.taskmgmt.exe.TaskInstance task fetch all properties left join fetch task.variableInstances varInstance"
|
When you are populating your DTO from your TaskInstance objects gathered in the HQL query, make sure you say "getVariableLocally("variableName") rather than the getVariable method. That is crucial.

[JBoss jBPM] - Re: jPDL: global event handlers
by bradsdavis
I am not sure of an official global event handler. I dont believe there is a way to do that, but here is one possible solution otherwise.
One option would be to write a log handler that executes on the different logs to send events. Most of the event types are logged, so you could get at the same data.
| <!-- A : org.jbpm.graph.log.ActionLog -->
| <!-- B : org.jbpm.context.log.ByteArrayUpdateLog -->
| <!-- C : org.jbpm.logging.log.CompositeLog -->
| <!-- D : org.jbpm.context.log.VariableDeleteLog -->
| <!-- E : org.jbpm.context.log.DateUpdateLog -->
| <!-- F : org.jbpm.context.log.HibernateStringUpdateLog -->
| <!-- G : org.jbpm.context.log.LongUpdateLog -->
| <!-- H : org.jbpm.context.log.HibernateLongUpdateLog -->
| <!-- I : org.jbpm.graph.log.ProcessInstanceCreateLog -->
| <!-- L : org.jbpm.context.log.DoubleUpdateLog -->
| <!-- M : org.jbpm.logging.log.MessageLog -->
| <!-- N : org.jbpm.graph.log.NodeLog -->
| <!-- O : org.jbpm.graph.log.TokenCreateLog -->
| <!-- P : org.jbpm.logging.log.ProcessLog -->
| <!-- R : org.jbpm.context.log.VariableCreateLog -->
| <!-- S : org.jbpm.graph.log.SignalLog -->
| <!-- T : org.jbpm.graph.log.TransitionLog -->
| <!-- U : org.jbpm.context.log.StringUpdateLog -->
| <!-- V : org.jbpm.context.log.VariableLog -->
| <!-- W : org.jbpm.context.log.VariableUpdateLog -->
| <!-- X : org.jbpm.graph.log.ProcessInstanceEndLog -->
| <!-- Y : org.jbpm.graph.log.TokenEndLog -->
| <!-- Z : org.jbpm.graph.log.ProcessStateLog -->
| <!-- 0 : org.jbpm.taskmgmt.log.TaskLog -->
| <!-- 1 : org.jbpm.taskmgmt.log.TaskCreateLog -->
| <!-- 2 : org.jbpm.taskmgmt.log.TaskAssignLog -->
| <!-- 3 : org.jbpm.taskmgmt.log.TaskEndLog -->
| <!-- 4 : org.jbpm.taskmgmt.log.SwimlaneLog -->
| <!-- 5 : org.jbpm.taskmgmt.log.SwimlaneCreateLog -->
| <!-- 6 : org.jbpm.taskmgmt.log.SwimlaneAssignLog -->
|
In the jbpm configuration, then just configure in your logger.
|
| <service name="logging">
| <factory>
| <bean class="you.logger.Class"></bean>
| </factory>
| </service>
|

[JBoss Tools (users)] - Deployment of JBoss Seam project created by JBoss Tools
by GermanDev
Hi!
I created a new JBoss Seam EAR project using the newest JBoss Tools and a local running JBoss AS 4.2.3GA under Windows Vista x64.
Now the project needs to be deployed to a productive system this is the same JBoss AS but running under Debian x32. I wondered there was no trace of the project within the "deploy" folders of my local server. I read in my documentation that this is where projects are being deployed to?!
I finally found the datasource file and the .ear folder (is this right that it isn't a file called *.ear but a folder?) but only in the directory "c:\my-eclipse-workspace\.metadata\.plugins\org.jboss.ide.eclipse.as.core\JBoss_4.2_Server\deploy\".
I copied the myProject-ds.xml and the .ear folder in the defaut\deploy folder of my productive server and started it. Even when the application started it behaved strange - the validation messages for example where old ones. Actions that work on my local server doesn't work on the remote one - even when they access the same database - I don't get errors but strange validation messages instead. For example I can't change my password because the application always says that the password is too short and does not match with the "verify password" field - what is actually does.
-> Might a reason be that I am locally using the "JDK6" version of the AS while the productive server uses the "JDK5" version instead?
-> How do I "build" that project correctly from JBoss Tools to deploy it to my remote server? (I can't mount that server at the moment, I can only copy files to it).
Thank you so much in advance!
