how to set configration data for DataSource?

I'm writing demo for DataSource block, which will get me JdbcConnection from
the pool.
I'm using
"org.apache.avalon.cornerstone.services.datasource.DataSourceSelector" to
get the DataSourceComponent from the excalibur package.

But i'm finding it difficult to set the configration data for this block.
Phoenix is throws exception at "DefaultSarDeployer".

I have gone through "Developing with Avalon" developer guide and Phoenix
assemblers guide. still i'm not getting how this has to be done.Can any one
please give me the sample configration data for the DataSource block. And
explain how it will work?

regards,

Could you tell us what the exception is? It would be easier to diagnose the 
problem that way.

I don't actually use it at this stage. Eung-ju could you describe it ... or 
even better javadoc it ? ;)

Try like this:

assembly.xml
--------------
...
<block
class="org.apache.avalon.cornerstone.blocks.DefaultDataSourceSelector"
  name="datasources" />

config.xml
----------
<datasources>
  <data-sources>
    <data-source name="default1"
class="org.apache.avalon.excalibur.datasource.JdbcDataSource">
       <!-- configuration for JdbcDataSource -->
    </data-source>
    <data-source name="default2"
class="org.apache.avalon.excalibur.datasource.J2EEDataSource">
       <!-- configuration for J2EEDataSource -->
    </data-source>
    ...
  </data-sources>
</datasources>
