How to set timeout runtime

[yogitabartake]

Is there any way to set a timeout period for an activity after the activity starts ? The timeout period will be dynamic in my case and I will be fetching it in the class that I call on that activity.So I need to set the timeout period after I fetch it.

Please guide me with some way to achieve the same...

Thanks for any reply in advance

Hi Yogita,

you could use expression in the duedate attribute.  So you could set a process variable and read it using expression.  Like this:

<timer duedate='#{proc_var}' />

Thanks a lot HuiSheng

But is it possible to set the timer for a java or a decision activity?

Hi Yogita,

Did you means that you want to create dynamic timer in the runtime?

Is it necessary?

[yogitabartake]

Well not exactly. I just want to set the timeout period runtime for a java and a decision activity.

Hi Yogita,

You can set a variable before timer create.  And let timer use this process variable for its duedate attribute value.  We cannot modify timer though java or decision activity directly.

If you really want to do that, you could use hibernate to access database directly, once you get the timerImpl,  you could do whatever you want to do.  But please notice that is not recommended.

What I meant to ask is can I have a timer transition or a timeout event on a java or decision activity in the following manner...

<java name="someActivity" >
    <on event="timeout">
      <timer duedate="10 minutes"/>
      <event-listener />
    </on>
    <transition name="go on" to="next step" />
  </java>

OR

<java name="someActivity" >
    <transition name="go on" to="next step" />
    <transition name="timeout" to="escalation" >
      <timer duedate="9 minutes" />
    </transition>
  </java>

Coz I have heard it can be used only for wait type of activities.Is that true?

Hi Yogita,

Yes, we cannot define a timer on an automatic actvity.  Because the automatic activity will execute and go to the next step immediately,  Even if you put a timer on it, the timer won't worked.
