JBPM5.4 Get Process and Node variables from ProcessDefinition

[mdegan]

Hi,

I am using jBPM5.4 in my custom web application. I want to auto-generate forms for the nodes based on the variables defined in the nodes. For this, I need to extract the input and output variables defined for the node. I do not seem to find a way to get the variable names and datatypes for the node variables. Since this activity has to happen before the process is made available to users, we will not have any processInstances. Please suggest a way to accomplish this.

Regards,

Manny

Hi Jose,

Not till now. Looks like the only way to achieve this will be to parse BPMN as XML and get the values for the appropriate tags. Havent figured out any other way to do this.

I was hoping to get some information on how auto form generation works on the jBPM designer, because my logic should be similar. But I havent been able to figure it out.

Too bad

I am facing a similar issue with bpms 6 (beta); i haven't found any solution yet; hopefully, they will put this in the API, but i am not sure about that

good luck finding a solution with this

Hi, mdegan. You can try this

((RuleFlowProcess)kbase.getProcess("{full.process.name}")).getVariableScope()

for get information about all variables defined in process from process-constructor.
