var body=”;

var num1 = $.request.parameters.get(‘num1’);

var num2 = $.request.parameters.get(‘num2’);

var answer;

answer = num1 * num2;      

body = answer.toString();

$.response.setBody(body);

$.response.status = $.net.http.OK;

function downloadExcel(){ 

    var body = ”;  

    var query = ‘SELECT TOP 500 \”TextId\”,\”Language\”,\”ISOLanguage\”, \”Text\”‘

     + ‘FROM \”SAP_HANA_EPM_DEMO\”.\”sap.hana.democontent.epm.data::texts” order by \”TextId\”‘; 

    $.trace.debug(query); 

    var conn = $.db.getConnection(); 

    var pstmt = conn.prepareStatement(query); 

    var rs = pstmt.executeQuery(); 

    body = “TextId \tLanguage \tISOLanguage \tText\n”; 

   while(rs.next())

   { 

        body += rs.getString(1)+ 

“\t”+rs.getString(2)+”\t”+rs.getString(3)+”\t”+rs.getString(4)+”\n”;
