RE: Urgent: Execution of pipeline at startup

2002-03-04 Thread Vadim Gritsenko 

Your component can implement:
 - ThreadSafe
 - Runnable
 - Startable
 - Stoppable
 - Configurable
 - Parameterizable
 - ...

Read "Developing with Avalon" on the jakarta.apache.org/Avalon for more
info. See also comments in these interfaces.

Then, you will have methods:
 - run()
 - start()
 - stop()
 - configure()
 - parameterize()


Your component should be declared in the cocoon.xconf. Declaration could
look like:



  
  



PS If you need logger, it is good idea to extend from AbstractLoggable.

RE: Urgent: Execution of pipeline at startup

2002-03-04 Thread Chitharanjan Das 

Thank you for your quick response.

After going thru the components information , sitemap basically consists
of information regarding components and pipelines.

I have designed a Component, which basically extends
org.apache.avalon.framework.component.Component and as you specified it
has I have embedded the logic in start() and run() methods..

The questions I have is
1. How do I register this components, currently in the sitemap, the
components defined are generators, transformers, serializers, actions,
selectors and readers?

Could you please briefly explain as how to register my component in the
sitemap.

2. The only method which is defined in the Component interface is a log
method. Which class/interface should I extend so that the particular
method (which will iunvoke my start())gets invoked during startup.

I hope I am clear...

Thanks for your information in advance,
Regds,
Chiths

You could write own ThreadSafe, Runnable, Startable Component. It will
be loaded and started automatically on Cocoon startup. You can do
whatever you want in the start() or run() methods.

RE: Urgent: Execution of pipeline at startup

2002-03-02 Thread Chitharanjan Das 


Hello,
It's not the precompilation of JSP or XSP I am talking about.
But caching of datastructures , role definitions, access-controls ,
schema of data structure etc.

These will be typically defined in a database.

So What I am looking for is a callback or a hookup to execute a pipeline
when cocoon starts up

Regds,
Chiths

I know of two possibilities: use the -precompile target when building
your
war or use a spider after startup so that all pages are generated then.

Urgent: Execution of pipeline at startup

2002-03-01 Thread Chitharanjan Das 

Hello,
I had raised this issue earlier...
Please confirm if this is possible at all.

I need to cache some data structures and some schema elements.

Is there a way to execute a pipeline or any other possibilities to cache
the information at COCOON'S startup.

Currently, I am performing this caching at first access.

I would surely like to cache the information at startup, rather than at
first access...

Could any of you please provide an approach and if already implemented,
please share the implementation.

Regds,
Chiths
