[Gvsig_english] load layer by code

[Claudio]

Hi and thanks,
yes, it's a simple extension like a button that load this shape file without a gui. The reference tutorial is the  extLoadPostgis in the official repository.
So, in gvSIG, I create a new View and click on the "load layer", but nothing happens...while eclipse return an exception error.

any suggest...?

thanks and regards,
claudio
