[Gvsig_english] Eclipse RCP with gvSIG

Fri Apr 8 11:53:26 CEST 2011

Dear José,

thank you for this information. I have signed these three groups to pursue and understand the developments of gvSIG. It would be preferable if the spanish speaking developers would take more interest on the international developer mailing list. I have learned spanish three years at school, but I have to take a look on my schoolbooks again before I can enrich this community :-) 

Do you have any information about some sample code for using the features of gvSIG like adding data to layers and so on? I am feeling a little bit left alone at this part...

Buen fin de semana :-)
Tobias

Hello Tobias,
I would like to say you where you can find more information to develop gvsig yourself:
- English spoken developers mailing list (https://lists.forge.osor.eu/listinfo/gvsig-desktop-devel): it has low traffic because there are not many gvSIG English spoken developers but you should also read and write in this list. Developers for other projects work together there.
- Spanish spoken developers mailing list (http://listserv.gva.es/cgi-bin/mailman/listinfo/gvsig_desarrolladores): it has high traffic because there are many and highly qualified developers. If you can read/write spanish you will have very good information to develop gvsig. 
- Public mailing list of the gvSIG Technical Steering Committee -TSC (https://lists.forge.osor.eu/listinfo/gvsig-desktop-tsc-pub): This list is probably the most important one for people who need to know how gvsig is being developed. 
The allowed languages for the TSC list are Spanish and English. Most of the discussion is done in Spanish but don't hesitate to ask in English if you have cuestions.  People there are open and they make a good documentation of their meetings that you can read if you can speak spanish.
Nice to see you in the gvsig lists!
Schönes Wochenende!
José

Dear Jordi,

thank you for your suggestion. My job is just to build a working prototype in Eclipse RCP. Other people will rack their brains for license issues :-) I will tell them regarding these obscurities.

With best regards
Tobias

Hi Juan Lucas,

I believe you are rigth, Tobias is able to distribute a plugin, that way he
is not mixing GPL code with EPL code, is the final user who do that.
My intention was only to advice Tobias to be careful with license
incompatibilities.

Cheers.
