Hi Venkat and Anindya, First, your questions (see below) are user questions and not dev questions so I have moved them over to the user list.
Second, your questions are very basic web development questions and not really OpenLayers specific. OpenLayers is a JavaScript library that runs in a web browser, so all the rules that apply to this development environment apply to OpenLayers. If you can not answer this question then you need to do more research and read some tutorials on web development BEFORE you start asking questions on OpenLayers User or the Dev lists. [2] So questions like, Can OpenLayers call .... can be more generally ask in terms of can any JavaScript web client call ... and how do they do that? Then you can look at the examples OpenLayers provides that do very simple things like you are asking. Once you have some basic understanding of OpenLayers and you need to more specific information, I'm sure there are plenty of people that are willing to give you some help. If you are asking to decide if you should pursue some additional investigation on your own then: 1) Yes, OpenLayers can call AJAX services - see the examples [1]. 2) Yes, OpenLayers has support for parsing various geostapial data formats - see the examples [1] 3) No Javascript running in a browser can talk to a Database without some kind of AJAX server application 4) All Javascript running in a browser can talk to web services as AJAX requests, but you have to deal with the "server of origin" issues. If you don't know what that means, google it. -Steve [1] http://dev.openlayers.org/releases/OpenLayers-2.9/examples/ [2] http://trac.openlayers.org/wiki/Documentation -------- Original Message -------- Subject: [OpenLayers-Dev] Can OpenLayers call a webservice? Date: Thu, 6 May 2010 18:51:23 -0700 (PDT) From: venkat.bapalu <[email protected]> To: [email protected] Hi, I was stuck up at the below implementations and am not able to move further. I have few queries on OpenLayers functionalities, Please let me know the possibility of the approach and the best way of implementing it !! 1. Can OpenLayers directly read the XML data with spatial information and display in web page? If this possible, please give any example 2. Can OpenLayers connect directly to any database (oracle) and publish the data on map? one way of connecting to the database is through the use of GeoServer with OpenLayers. But I want to use only OpenLayers to connect to the oracle database. Please let me know how to achieve this? 3. Can OpenLayers using JavaScript (AJAX) can call a Oracle BPEL webservice? If so how to customize the openlayers to call the webservice Regards Venkat -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Can-OpenLayers-call-a-webservice-tp5017473p5017473.html Sent from the OpenLayers Dev mailing list archive at Nabble.com. _______________________________________________ Dev mailing list [email protected] http://openlayers.org/mailman/listinfo/dev -------- Original Message -------- Subject: [OpenLayers-Dev] Can OpenLayers call a java program Date: Thu, 6 May 2010 19:34:36 -0700 (PDT) From: Anindya <[email protected]> To: [email protected] Hi, Can OpenLayers call a java program?
