Hi All, I am very new to SOA and just have the idea of it. All the articles I read I just could understand that it is just to setup a standard and passing the data in XML format. But can anybody tell me why to have a new standard when we have HTTP in place to pass the same type of data. It also supports session management and security(HTTPS) in a standard way. Its not like I am against the SOA but I feel we already have SOA implemented everywhere but we just need to make applications more structured to generate output of different type based on request. I feel the basic thing we assume that normal application design will generate html(written in JSP,ASP etc.) as an output which is for browser only but isn't it possible to send same data in form of any xml or other format generated by same JSP, ASP code. Afterall whatever data is being passed will have to be parsed to proper type at consumer end, because all is just array of char. And also in both the cases we need to tell the consumer about the data format needed to be transfered. I feel in same MVC approach if we have multiple selectable views(which can be selected based on request) to generate output in different format we can obtain integration between different applications following the same http protocol standards only. I mean what is the need of converting data to xml then set in http requst then on server take it from request then again unparse the xml then parse the output again in xml then add in response then take the data out from response at client and again unparse it from xml.
