How to use an instantiated variable into all the script tasks in a single jbpm process?

[catherinesjy]

Dear all,

My jBPM process (BPMN) is like:  START -->  DirectoryImport  -->  Process  -->  DirectoryStorage  -->  END

I have three functions wanted to be invoke in each of the tasks in the process:

     public void doDImport();

     public void doProcess();

     public void doDExport();

All the three functions are in com/myutil/ProcessClass.java

What I want to do is like:

1. Import 'com.myutil.ProcessClass' into 'DirectoryImport', 'Process', and 'DirectoryStorage'

2. Instantiate 'ProcessClass' in 'DirectoryImport' script task:

ProcessClass processClass = new ProcessClass();

3. Use the instantiated variable in all the tasks:

     code in 'DirectoryImport' script task:

ProcessClass processClass = new ProcessClass();
processClass.doDImport();

     code in 'Process' script task:

processClass.doProcess();

     code in 'DirectoryStorage' script task:

processClass.doDirectoryStorage();

But, the problem is:

The variable 'processClass' instantiated in 'DirectoryImport' cannot be use in 'Process' and 'DirectoryStorage' , since it is not a global variable.

How can I deal with this problem?

Thank you all!

Hi Catherine,

Why are you using Script Tasks?

You can use process variables and WorkItemHandlers for that and it will be way better for the maintainance point of view.

So something like:

Map <String, Object> params....

params.put("processClass", new ProcessClass());

startProcess(<your process id>, params)

From inside the workItem handler you will be able to access to the processClass process variable and execute the methods that you need.

Hi Mauricio,

Thank you so much for your suggestion! I finally find the solution to my question using process variable with WorkItemHandler.

Really thanks a lot for help!

Hi Mauricio,

Sorry to trouble you but I have a new problem with the same case. I posted it on the How to apply process variable to custom java class?.

Could you help me with that? Thanks a lot!
