[OpenLayers-Users] [OpenLayers-Dev] Can OpenLayers call ......

[Stephen Woodbridge]

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.

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
