Hi, ok, with next release :-) damned deadlines...
Btw, are there any examples you recommend to look at to start with
ServiceManager and Serviceable?



ServiceManager is semantically equivalent to ComponentManager. They both have a lookup and relase operation. The only significant difference is that code written for a component manager may narrow an object to Component - whereas code for a ServiceManager allows java.lang.Object.

Rolling over is easy: (a) replace Composable with Serviceable, (b) replace the compose operation and ComponentException with service and ServiceException and update the imut argement to be a ServiceManager (c) replace any ComponentManger references with ServiceManager, (d) check for any other org.apache.avalon.component imports and handle as appropriate.

Cheers, Steve.

Heh, not that easy, removed one, compiled and got error:

Incompatible type for method. Explicit cast needed to convert...

when

compMgr.put( MyClass.ROLE, this);

shall I replace Block with Component?



I would recomend you move to using ServiceManager and Serviceable rather
than
ComponentManager if it is possible.

Hi, since it has been deprecated what shall I do with my code, just
remove Block from every place?


Yep.
