Hi Dave,

Hmm, have you used modules before? Have you written some modules (including for your private use)?

No Laurent. That is why,i am stuck how to write this framework. Recursively how can i extract .jar, .ear,.tar etc.. and find files that i need.I need to automatically extract jar and ears inside tars as well.

I did something like this back in 5.6 that required some really funky workarounds. Today I would recommend the following approach (what I did with PGObject's registered type system).

1. You have a module private (lexically scoped) hash variable connecting an extension to a plugin class name.
2. You specify an interface for that plugin. We could call it extract_files().
3. You call it somehow like this:

   "$plugin_registry->{$extension}"->can('extract_files')->($path);
   [download]

This approach allows you to add whatever extensions you want and have them register themselves (through an API) which can check for the extract_files interface and add to the registry.
