Re: [Gwt-openlayers-devl] WFSprotocol and Vector Layer

[Edwin C. <com...@gm...>]

Hi Mikael,

Sorry for the toe stepping. I will not push the additional setters for
version, srsName and will await your changes.

As for the proxy. I am not so literate with servlets, so I am reading
up and experimenting a bit. The resourceUrl/targetUrl for GET/POST
should be replaced by one parameter I think (e.g., remoteUrl) and the
method should be inferred from the request to the proxy. Are you good
with servlets? Would you have time to work on the proxy servlet?

Greetings,
Edwin
