Hi,
I have developed a "BackgroundProcessManager" as a Cocoon Action.
*************
What it does
*************
With it, multiple requests (to Cocoon pipelines) can be processed at a time
and their responses can be saved to the filesystem.
After the reponses have been saved, for each process (BGP) an email is
generated which gives a feedback about the generation process (if everything
worked fine, or if there were errors).
So everytime my action is called, there are 2 requests to Cocoon. Firstly
the request to a Cocoon Pipeline which does a (time intensive)
xml-generation and transformation and secondly the request to the Email
Pipeline.
So far so good.
***************
The Problem
***************
The action has a configuration parameter, which defines the maximul number
of requests that can be processed in parallel. (I implemented the
Parameterizable interface, to get the parameter value.)
<map:action logger="bgpm" name="bgpm"
src="bgpm.acting.BackgroundProcessManager">
<parameter name="max_parallel_bgps" value="3"/>
</map:action>
When I change the parameter while requests are processed, I encounter an
"IllegalStateException. You cannot lookup components on a disposed
ComponentLocator".
Okay, one solution whould be, not to change the parameter while requests are
processed.
However this is not the best solution.
Does anybody have a better solution. What the right way to do ist?
can somebody explain the Background of this Exception? Why is it thrown?
Regards,
Stephanie
