How to use property value in timer configuration

hiten_rastogi1

Hi,

I am using activiti with Alfresco to create a multilevel approval workflow.

I am thinking of using a property in timer config e.g. <timeCycle>${cronExpression}</timeCycle> instead of <timeCycle>0 0/1 * * * ?</timeCycle>, where cronExpression=0 0/1 * * * ?.

Can someone please help me out how can I achieve this.

Hi hitenrastogi!
I think you can simply set process variable cronExpression and then use expression ${cronExpression} in TimerCatchingEvent

Hi Warper,

Thanks for your reply but this is not what I am looking for, I want that variable to be preferably in something like alfresco-global.properties, if possible, so that I can change the cromExpression without restarting the server and redeploying the service.

Noone limits you, read whatever property you want from whatever configuration you want. You can use spring bean, java delegate or whatever JUEL-available configuration reader you want. TimerCatchingEvent simply runs JUEL expression to get timer definition. One of my processes reads timer duration from LDAP.

I don't think such property can affect timer jobs in activiti database, though. That is, once timer is set, it needs to be fired before it can change configuration (reread properties, reevaluate expression) .
