[Gvsig_english] groovy

[Jorge Sanz]

Hi Robert,

Do you want to execute groovy compiled classes or to execute dynamic compiled scripts?

I've tested recently the dynamic execution of groovy scripts in gvSIG (sorry but I haven't any examples here at work) loading the script files. I created a new extension (like any other gvSIG plugin) with its config.xml and so on. In my extension execute method I've tried to parse a groovy script[1].

One thing you should care about is to pass the extension classloader[2] to the compiler in order to let your groovy scripts to access gvSIG classes. I've successfully accessed andami classes (like PluginServices for example) but I've experienced casting problems with other libraries like FMap (to access for example to the active view's MapControl).

Anyway (IMHO) developing extensions for gvSIG is easier in Java than in scripting languages.
