Pessoal podem ajudar-me no seguinte:<br>
Tenho esta parte do código:<br>
<br>

<br>
<br>
Significa que o mapa vai estar na projecção 900913. Neste exempo eu
quero mudar a area a ser apresentada por isso tenho de mudar o
maxExtend certo?<br>
A questão é se eu no geoserver definir o srs como 900913 e calcular,
tenho os valores da bounding box,e é so substituir ou estou errado?<br>
<br>
Pelo que percebi:<br>
<br>
<pre><span class="o">-</span><span class="mi">20037508
(left = min X)
</span><span class="o">-</span><span class="mi">20037508</span><span class="p"></span>
(bottom = min y)
<span class="mi">20037508</span><span class="p"></span>
(right = max X)
<span class="mf">20037508.34</span><span class="p"></span>
(top = max y)
Estou correcto?
obrigado

Oi<br>
<br>
Pelo que vejo:<br>
<br>
1) Nao tens a proxy instalada para poderes contactar <a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://localhost:8080">http://localhost:8080</a><br>
<br>

href="http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#HowdoIsetupaProxyHost">http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#HowdoIsetupaProxyHost</a><br>
<br>
Ate teres a proxy instalada o browser nao vai pedir nada ao
servidor...<br>
<br>
2) Tens duas vezes projection:<br>
projection: 'map.getProjectionObject()',<br>
reproject: 'True',<br>
projection: new OpenLayers.Projection('4326'),<br>
<br>
Geralmente JS usa o ultimo valor definido, portanto estas a usar
projeccao 4325<br>
<br>
3) O uso correct the OpenLayers.Projection e' com EPSG<br>
<br>
OpenLayers.Projection("EPSG:4326")<br>
<br>
All the best<br>

Acho que o problema é mesmo os wms que não são reprojectados:<br>
Reparem neste exemplo que fiz:<br>

Simplesmente não aparece o wms<br>

Bons dias<br>
<br>
<br>
Bem, se tens acerteza que o wms funciona sem problemas sem o
layer proprietario, o mais provavel e' que o WMS nao supporta
EPSG:900913 ou gera um erro quando fazes o pedido.<br>
<br>
No firebug, ve os pedidos feitos pela pagina (Seccao Net) e ve
o pedido feito ao servidor e a resposta data.<br>
<br>
Por exemplo tenho um sistema que faz o seguinte pedido: <br>
<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://localhost/rasdaman/wms.py?LAYERS=rasdamanImage&FORMAT=image%2Fpng&TIME=2011-06-20&STRATEGIES=%5Bobject%20Object%5D&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A900913&BBOX=-6300637.7833253,4684889.401321,6076045.8348875,10359574.380423&WIDTH=1265&HEIGHT=580">http://localhost/rasdaman/wms.py?LAYERS=rasdamanImage&FORMAT=image%2Fpng&TIME=2011-06-20&STRATEGIES=%5Bobject%20Object%5D&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A900913&BBOX=-6300637.7833253,4684889.401321,6076045.8348875,10359574.380423&WIDTH=1265&HEIGHT=580</a><br>
<br>
Experimenta a fazer um pedido ao teu WMS usando
SRS=EPSG%3A900913<br>

Jorge,<br>
<br>
Sim lembro-me.Esclarece-me só a seguinte dúvida, o que é que
o browser não está a conseguir ir buscar na tua opinião mais
precisamente? É que ele vai buscar o layer proprietário, os
wms é que não. Mas noutros exercicios que efectuei sem o
layer proprietario ele ia buscar tudo.<br>
<br>
<br>
Obrigado<br>
bom fim de semana<br>

<p><font size="2">Oi<br>
<br>
Parece tudo em ordem, mas tens um ligeiro problema :)<br>
<br>
Lembras-te da explicacao relativa a cross-domain, ou
seja podes acecer a outros URLs partir de Javascript
?! Pois quando tens um url com uma porta diferente
tens a mesma situacao, ou seja:<br>
<br>
<a moz-do-not-send="true" href="http://localhost:8080">http://localhost:8080</a><br>
<br>
è um URL differente e tens de usar uma proxy para
buscar os resultados. Eu sempre pensei que mesmo com
uma porta difererente nao haveria problemas mas à
alguns meses algume teve o mesmo problema e foi tudo
explicado no mailing list, acho que podes procurar no
google pelos emails mais antigos.<br>
<br>
Alem disso, tens o WMS a funcionar a 100%?
Experimentaste a fazer uma pedido com EPSG:900913 ??<br>

Tentei assim:<br>
<br>
<a moz-do-not-send="true"
href="http://pastebin.com/WLkRVbxu">http://pastebin.com/WLkRVbxu</a><br>
<br>
<br>
Mas continuo sem sucesso, só é visivel o layer
proprietário. Nem sequer<br>
aparece o "+" do layer switcher, não percebo o
porquê...<br>
<br>
Alguma sugestão?<br>
<br>
Obrigado<br>
<br>
<br>
PS: O firebug tb não detecta nenhum erro.<br>
