Dynamic Block Deployment

[Daniel Krieg <dk...@kc.rr.com>]

Is it possible to dynamically add/remove Blocks within a SAR?  With Catalina Sevak, I am attempting to use a BlockListener to assemble the different Blocks within the application.  What I would like to do is declare the Blocks within the assembly.xml but be able to dynamically add services based upon Catalina's con/server.xml file.   For example say I have declared a block

<block name="Connector" class="org.apache.avalon.apps.sevak.blocks.catalina.StandardConnectorWrapper">
    <provide name="bootstrap" role="org.apache.avalon.apps.sevak.services.Bootstrap"/>
</block>

This describes the block and the block that fulfills its dependencies that I want.  However, if the CatalinaAssembler (BlockListener),  parses the ${catalina.home}/conf/server.xml it may discover that two "Connector" Blocks are needed.  I would like to be able to deploy another Service instance into the Application.  Is this possible/desireable?
