using actions in flow

[Michael Wolf]

Hello,
after I searched the net for three days, asked a developer and posted in 
the cocoon-user mailing list all I found for my problem is the same 
unanswered question.

So I decided to post in this mailing list, because this seems to be a 
problem no one besides the developers is able to solve.
-----------------------------------------------------------

I want to use a modular Database Action in my flowscript.

I tried this approach:

myAction = cocoon.getComponent(???);
result = myAction.act("mod-db-sel","",{"table-set" : "login_check"});
cocoon.release(myAction);
The cocoon.getComponent method expects a component id, but how do I get 
this id?

I tried

myAction = 
cocoon.getComponent(Packages.org.apache.cocoon.acting.modular.DatabaseSelectAction.ROLE);

but that didn't work.

For completeness here is the action description in the 
sitemap/components/actions section:

<map:action name="mod-db-sel" 
src="org.apache.cocoon.acting.modular.DatabaseSelectAction">
   <descriptor>descriptors/database.xml</descriptor>
   <throw-exception>false</throw-exception>
</map:action>

So please tell me how this action is called from the flowscript.
Thanks for your help,
Michael
