Oi<br>
<br>
Um conselho, tenta usar o pastbin (<a class="moz-txt-link-freetext" href="http://pastebin.com/">http://pastebin.com/</a>) assim
mandas so um link em vez de uma catrafada de javascript<br>
<br>
O que se passa em e' que ao selectionares a camada OSM ela fica
sobreposta a camada wms_ruas e deixas de ver, o que e' logico :)<br>
<br>
Talvez a solucao seja adicional as propriedades da camada OSM algum
valor de transparencia ('opacity': 0.5)<br>
<br>
Mas uma pergunta, pelo que vejo tens uma baseLayer que bem de um WMS
+ uma camada com Ruas, nao consiguo percebe a utilidade da OSM.<br>
<br>
Nao basta usar a OSM como baseLayer + WMS_ruas ?<br>
<br>
Normalmente o uso mais comum do OpenLayers e' teres uma image raster
e depois em cima varias camadas vectoriais, ja que nas camadas
vectoriais e' mais facil de modificar as transparencias de cada
objecto<br>
<br>
Alguem tem mais ideas, sugestoes ?<br>

Podes meter a layer onde quiseres sem grandes problemas, ate
podes chegar a este ponto:<br>
<br>
map.addLayer(new OpenLayers.Layer.OSM());<br>
<br>
Eu nao sei o que estas a tentar fazer mas penso que queras que
OSM seja a baseLayer ? Talvez isto funcione ?<br>

Obrigado Jorge. Já eliminei os erros no entanto o
openlayers não está a carregar o layer ruas, a página abre
mas sem eu conseguir ver o layer.<br>

Tentei wms_ruas.getExtent() no firebug e obtenho o
seguinte erro: <span role="presentation" class="objectBox
objectBox-errorMessage hasBreakSwitch "><span
class="errorMessage ">ReferenceError: wms_ruas is not
defined.<br>
Penso que não está a conseguir ir buscar o layer ao
geoserver, alguma segestão do que poderá ser?<br>

Obrigado pelas repostas de todos<br>

<br>
</a></div>
</blockquote>
"OpenLayers is not defined" acho que este e' o error que
tens, parece que a pagina nao carregou o OpenLayers.js.
Ve no tab "Net">js do firefox se ele carregou o
OpenLayers, experimenta usar a versao online: <br>
<br>
<br>
<script type="text/javascript" src=<a
moz-do-not-send="true" class="moz-txt-link-rfc2396E"
href="http://openlayers.org/dev/OpenLayers.js">"http://openlayers.org/dev/OpenLayers.js"</a>></script><br>
<br>
<br>
Eu experimentei: var bounds = new
OpenLayers.Bounds(-23941, 208039,-21480, 210148);<br>
<br>
E esta tudo OK<br>
<br>
Quanto aos bounds, experimenta meter os bounds iguais
aos descritos no WMS (faz um pedido getCapabilites),
depois de teres adicionado o a layer wms_ruas, podes
usar wms_ruas.getExtent():<br>
<br>
map.zoomToExtent(wms_ruas.getExtent());<br>
<br>
So uma chamada de atencao o object wms_ruas so esta
totalmante operacional depois de adicionado ao mapa e
depois de feito o pedido ao servico pelo openlayers, ate
teres o objecto totalmente criado certas variaveis e
metodos dao error.<br>

Penso que seja porque os bounds estão mal

map.zoomToMaxExtent e map.getExtent no layer

Isto e' un link pro CSS (cascade style sheet) que
define como varios elementos vao ser rendizados
(rendered), ou seja cores, tipos de letras icons, e
onde os menus (exemplo: LayerSwitcher) vao aparecer

a fazer alteracoes :) .Se nao sabes trabalhar com

<br>
Basicamente em Javascript tu nao podes chamar um URL
que nao esteja no mesmo dominio, por exemplo se o
teu site esta em <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://localhost">http://localhost</a> mas o
WFS esta em <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://WFSsite.pt">http://WFSsite.pt</a> o
codigo de javascipript nao pode aceder a <a
moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://WFSsite.pt">http://WFSsite.pt</a>,
esta situacao eh conhecida por "cross domain" da uma
vista de olhos na internet<br>
<br>
Actualmente os browsers mais recentes podem
contactar outros dominios se o servidor no outro
dominio suportar a norma CORS: <a
moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://www.leggetter.co.uk/2010/03/12/making-cross-domain-javascript-requests-using-xmlhttprequest-or-xdomainrequest.html">http://www.leggetter.co.uk/2010/03/12/making-cross-domain-javascript-requests-using-xmlhttprequest-or-xdomainrequest.html</a><br>
<br>
Basicamente, a melhor estrategia eh de instalar a
proxy no teu servidor e deixar que o openlayers
trate do assunto.<br>
<br>
Normalmente, o firebug manda-te um erro quando tens
cross-domain (normalmente o browser nao diz nada e
nao faz nada quando tens cross-domain)<br>

var map=null; Bem uns gostam cozido outros gosta de

que eh uma variable global, que pode ser acedida por
qualquer funcao. Normalmente um erro comum e' meter
"var map" dentro do init()<br>
<br>
Pessoalmente meto o map e as layers sempre fora da
funcao de inicializacao, ja que variaveis globais
parecem logo no firebug.<br>

<b>3) NO exemplo em questão que segue em baixo, temos de por o schema para o layer do geoserver em questão, trata-se de
um url? Como posso descobrir url para o layer que pretendo? Tentei trocar o nome deste exemplo (participante)
por um layer que tenho e colar no browser mas não abre nada...
POdem dar-me uma dicas?

Eu raramente trabalho com WFS e estive a ver no
codigo do openlayers (Protocol/WFS/v1.js) temos a
seguinte definicao da propriedade schema:<br>
<br>
/**<br>
* Property: schema<br>
* {String} Optional schema location that will
be included in the<br>
* schemaLocation attribute value. Note
that the feature type schema<br>
* is required for a strict XML validator
(on transactions with an<br>
* insert for example), but is *not*
required by the WFS specification<br>
* (since the server is supposed to know
about feature type schemas).<br>
*/<br>
schema: null,<br>
<br>
<br>
Basicamente e' um URL que define o schema dos dados
em XML e que pode ser usado para validar os
conteudos, no exemplo passas um DescribeFeatureType
que gera un esquema que define a estrutura do XML
dos teus dados. Em varios exemplos nunca vi o uso
do schema:<br>

Eu uso mais mapserver, ja que nao me dou muito bem
com o JAVA (serei demasiado calhau?) <br>

uma livraria no localhost e' mais rapida para fazer
o upload e nao estas dependente de "terceiros" <br>
<br>
E para concluir: O firebug e' o melhor amigo do
Homem (depois do cao e' claro)<br>
<br>
<br>
Bom feriado, eu vou marfar <br>
