Hi all,

        I have a custom object?(card)  in salesforce with field (service order) . I would like to get information from oracle db that match this service order.

What approach would be better?
What about service calls?
I am baby on this case of integration?
Can anybody help me?
If i do REST api,
i have some questions.
I could find a blog :-
https://developer.salesforce.com/blogs/developer-relations/2013/08/integrating-force-com-using-xml-in-apex.html
Can i do something like this?
1. When the call is made to the XML server, is the web browser on the user's PC making the call or is the SalesForce.com server making the call?  
2. Is it makes a difference in how we will need to navigate around the firewall issue?
3. Which is good to use SOAP / REST?
4. What is difference between them?

 Thanks in advance.

Hi all,
    I am using a custom button in event page layout for some interrnam pupose. I have used the code given below to populate the 'Add attachemnt page' from custom button


Code:
URL.getSalesforceBaseUrl().toExternalForm() + '/p/attach/ActivityAttach?relatedListId=' + eventID +'_RelatedActivityAttachmentList&retURL=%2F'+eventID+'%2Fe%3FretURL%3D%252F'+eventID+'&pid='+eventID+'&type=00U';

Link retrieved :
https://cs10.salesforce.com/p/attach/ActivityAttach?relatedListId=00UJ0000009yQ2F_RelatedActivityAttachmentList&retURL=%2F00UJ0000009yQ2F%2Fe%3FretURL%3D%252F00UJ0000009yQ2F&pid=00UJ0000009yQ2F&type=00U


But the issue is after attachement return to 'Edit page ' of event simply like standared functionalty. Instead, i have to return to the view page after saving the attachment. What change i should made for it?

Thanks in advance.
