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
