Cornerstone-datasource

[idris]

Hi all,
  I'm trying to create a datasource componet using cornerstone, but I  
keep getting the following exception whenever I start phoneix.

Phoenix 4.0.3

There was an uncaught exception:

Unable to create BlockInfo as are unable to locate resource  
"org/apache/avalon/cornerstone/blocks/datasources/ 
DefaultDataSourceSelector.xinfo".

My question is, am I supposed to create the xinfo file, and I am, where  
do I place it and what is the purpose of the file. All help would be  
very much appreciated. I've also posted the content of my assembly and  
config  files. Thank you
