Sharing variables across jbpm processes

[r3vans]

Hello there.

I want to define in one place a setting that is used as input to timer events in many processes. The value will change from environment to environment so I want to localise it.

I guess that global variables should work...

I defined the setting in the timer

- Timer Delay: #{statusPollInterval}

I then tried to set the global variable.

  - kSession.getGlobal.set("statusPollInterval", "2s") didn't seem to work

  - kRuntime.setGlobal.set("statusPollInterval", "2s") gave me an unexpected global message

- The following spring config also give unexpected global.

<drools:script>

<drools:set-global identifier="statusPollInterval">

<bean class="java.lang.String">

<constructor-arg value ="2s"/>

</bean>

</drools:set-global>

</drools:script>

Q1. Is a global variable the best approach for shared settings like this?

Q2. If so, what am I doing wrong? Do I have to declare the global in a drools:resource?

I have searched previous discussions on globals but have not managed to get the answer. I am new to jbpm so would be grateful for anywone with the patience to assume little prior knowledge.

My configuration is currently all in spring config.

Many thanks,

Richard

Hi Richard? Where are you trying to do:

kSession.getGlobal.set("statusPollInterval", "2s")

kRuntime.setGlobal.set("statusPollInterval", "2s")

That syntax is not even Java

if you have access to the Knowledge Session you just do: ksession.setGlobal("statusPollInterval", "2s");

If you don't have access, for example inside a process itself, you can use the kcontext object to access the knowledge runtime

kcontext.getKnowledgeRuntime().setGlobal("statusPollInterval", "2s");

That should work inside the processes and the rules.

Cheers

Thanks. Just a slip of the fingers. These are the two things I tried (written more carefully)

kSession.getGlobal().set("statusPollInterval", "2s")

kRuntime.setGlobal("statusPollInterval", "2s")

The second "worked" in that it seems to have set a global variable. However when I executed the process I got an "Unexpected global [statusPollInterval]"

Any ideas?
