doubt in displaying PDF documents

Presto doesn't currently support PDF files for upload. However, that doesn't necessarily mean that you cannot accomplish what you need to. If you can host the PDF files in your web server, or in the same application server as the Mashup Server, then even a simple link to that URL will open the PDF file.

Can you explain a little more exactly how you need to have users select a PDF and then open it?

 Even i  thought of accomplishing that with the help  of a web server, since  i thought there  might be an hidden option i was posting this question.I will explain you the scenario. There are 12  pdfs. i  should be able to select one at a time according to  the input . So if my input is '1' i  wanted to  display the first pdf and  if the input is '2' i  wanted to display the second  pdf.Seeking your help in this regard.

Thanks,

It's still not clear to me what you actually want. So some more specific questions:

1. Are you creating a custom App?

2. Are the 12 documents known? So maybe a simple HTML page with 12 links that users can click is good enough?

3. If not, can you please explain the steps you expect a user to take to select a document? And what, if anything, you expect this custom App to display when it first opens?

          I  am  creating a custom app. I  have written a JSP/servlet coding to display a  pdf  for a particular ID and runs on a web server . In the mashboard i have created an App  of  using default features of presto which displays data according to the ID. Now i want to fetch a document in the JSP/servlet web app  according to the ID  chosen in the default mashboard app. In short i  want to make the JSP/Servlet web app interact with the Mashboard App. The ID  should be passed from the mashboard app to the JSP/Servlet on a clicking , and the JSP/servlet and mashboard app should interact.

Sounds like you need to write a simple custom app which subscribes to a topic, published by the other app when a row is clicked, constructs an iframe which points to your JSP, passing the doc id as a url param.  Something like this:

Sample.IframeApp = function( app ) {              

       var root = jQuery(app.rootElement),     

       doc;           

       // subscribe to anything that publishes a rowclick event 

       app.subscribe('*.rowclick.*', function(topic, data){
        if(data.documentId && data.documentId != doc){
            var w = app.width,
            h = app.height;
            doc = data.documentId;
            root.html('<iframe style="width:'+w+'px;height:'+h+'px;" ' + 

               'src=http:/path-to-my-jsp/myjsp.jsp?documentId="'+doc+'" ></iframe>');
        }
    });
}
