Hi All,
I am trying to create a sample workflow based on a business process. I am getting
exception as "could not parse knowledge" when i have anything other than a
parallel gateway ( ie for only parallel gateway there are no errors , for rest all
gateways there are errors ) it gives error. The examples provided by jbpm git does the
same as below.
| | | KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); |
| | |
kbuilder.add(ResourceFactory.newClassPathResource("looping/Looping.bpmn"),
ResourceType.BPMN2); |
| | | return kbuilder.newKnowledgeBase(); |
The only change with my code is that i am using it as below.
kbuilder.add(ResourceFactory.newUrlResource(url),
ResourceType.BPMN2);
Is there a problem with this or the other gateways are still not supported ? If they are
supported then any idea why "kbuilder.newKnowledgeBase();" throws "could
not parse knowledge" exception.
Regards
Prashanth Karnam

Could you please share the full stacktrace of the exception? In the case of XOR gateways,
how are you defining the condition of the branches? How are you modeling your processes?
Are you using eclipse, guvnor, or are you ding them manually in plain xml?
As far as I know, complex gateways are not supported by jbpm5. The supported gateway types
are: Parallel (AND), Inclusive (OR) and Exclusive (XOR).

Hi Esteban,
I am using Data based XOR gateway. The condition for the branches are defined in Java. The
modeling is done in guvnor ( oryx ).
the stack trace of the problem is as below , this is hit as one of the methods containing
kbuilder.newKnowledgeBase() is hit.
java.lang.IllegalArgumentException: Could not parse knowledge.

Hi saig,
While debugging i do have the variable in processinstance. Does it mean that we need
to define this variable in the variable definition of the process while designing in the
oryx ?
we are adding these variables while starting the process startProcess( , , Map Params
).
Hi Mauricio,
I am trying to evaluate the value of result==true because in the backend i am having
a set of criterias which i evaluate and put the result as true of false into this
variable. I want the XOR to branch based on this result value. If its true ( meaning the
criterias are met in the backend ) then it should branch one way otherwise the second.
Hence i chose condition expression as java and the expression as return result ==
true;
For the senario explained above can you please let me know what is the way of
defining the process / condition in Oryx ?
Regards
Prashanth Karnam
