In the case of the new scripting plugin available in gvSIG 2.0, our 
initial plan is to provide access to all (or almost all) the gvSIG Java 
API from any script, as the supported scripting languages allow to call 
Java code (bytecodes actually) more or less easily. So to create a 
script you will be able to use the same documentation and examples 
available to develop gvSIG java plugins.

In the plugin's current state you have access to the gvSIG 2.0 core Java 
API, and some work has still to be done so any gvSIG plugin is able to 
make its own API available to the scripts.

That's our idea for the gvSIG 2.0 initial release. In the future we 
would like to use the scripting languages facilities to create a DSL [1] 
to make gvSIG scripting easier, but can't tell for sure and for which 
scripting languages. It will depend on available resources and if there 
are any volunteers.

Just in case anyone is interested, the scripting languages available in 
the scripting plugin are:

- Python (Jython)
- Ruby (JRuby)
- Groovy
- Javascript/ECMAScript

We planned initially to include Beanshell support also, but if you want 
to use the Java syntax, you can do it through Groovy.
