[Portugal] duvidas sobre openlayers

Terça-Feira, 13 de Dezembro de 2011 - 06:11:22 EST

Oi

Pelo que vejo:

1) Nao tens a proxy instalada para poderes contactar http://localhost:8080

http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#HowdoIsetupaProxyHost

Ate teres a proxy instalada o browser nao vai pedir nada ao servidor...

2) Tens duas vezes projection:
projection: 'map.getProjectionObject()',
reproject: 'True',
projection: new OpenLayers.Projection('4326'),

Geralmente JS usa o ultimo valor definido, portanto estas a usar
projeccao 4325

3) O uso correct the OpenLayers.Projection e' com EPSG

OpenLayers.Projection("EPSG:4326")

All the best

Jorge
