Thanks for your comment, it helped me a lot. Indeed that's the "problem".
I guess the next step is to create a good response so the RPC works. Or is
there any better solution? (I can't avoid the cross-site situation)
I've overriden the doOptions method in the servlet with the following code:
@Override
protected void doOptions(HttpServletRequest req, HttpServletResponse
res){
res.addHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS");
res.addHeader("Connection", "Keep-Alive");
res.addHeader("Keep-Alive", "115");
res.addHeader("Access-Control-Allow-Origin",
req.getHeader("Origin"));
res.addHeader("x-gwt-permutation", GWT.getPermutationStrongName());
res.addHeader("x-gwt-module-base", "
http://localhost:8084/AnalisiHeuristic/cat.udl.griho.AnalisiHeuristic.Main/
");
}
But it's not working yet, what am I doing wrong? isn't this the good
approach? :(
