    I am generating pdf file using below code
    Code:
    public void getTaskreportPDF(Session openSession,HttpServletRequest request,
                HttpServletResponse response) {
    		try {	
    Class.forName("com.mysql.jdbc.Driver");
               Connection con = (Connection) DriverManager.getConnection("jdbc:mysql://localhost/contact","root","root");
    			
    			Map params = getParameters(openSession);
    			Date date = new Date();
    			String reportfileName = "report"+date.getDate()+"-"+date.getMonth()+"-"+date.getYear()+"-"+date.getTime()+".pdf";
    		   JasperDesign jasperDesign = JRXmlLoader.load(this.getClass().getResourceAsStream("/com/gantt/report/ganttreport.jrxml"));
               JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
               
               JasperPrint jasperprint = JasperFillManager.fillReport(jasperReport, params,con);
           		
       		JRAbstractExporter exporterPDF = new JRPdfExporter();
               exporterPDF.setParameter(JRExporterParameter.JASPER_PRINT, jasperprint);
               exporterPDF.setParameter(JRExporterParameter.OUTPUT_STREAM, response.getOutputStream());
               response.setHeader("Content-Disposition", "inline;filename="+ reportfileName);
               response.setContentType("application/pdf");
               exporterPDF.exportReport();  
    		} catch(Exception exception) {
                System.out.println("Error occured " +exception.getMessage());
            }
    	}
    when i view my firebug net tab i am getting response as

    my response is correct and i am getting the pdf file having size of 4 kb. but the problem is that the download dialog window is not available. so help me to find my problem so I can solve it.

    my app.js is
    Code:
    Ext.onReady(function() {
        Ext.QuickTips.init();
        
        App.init();
    });
    
    
    TaskPriority = {
        Low : 0,
        Normal : 1,
        High : 2
    };
    
    
    App = {
    
    
        // Initialize application
        init: function () {
    	
    	//create the downloadframe at the init of your app
    	this.downloadFrame = Ext.getBody().createChild({
    	                tag: 'iframe'
    	                    , cls: 'x-hidden'
    	                    , id: 'iframe'
    	                    , name: 'iframe'
    	            });
    	//create the downloadform at the init of your app
    
    
    	            this.downloadForm = Ext.getBody().createChild({
    	                tag: 'form'
    	                    , cls: 'x-hidden'
    	                    , id: 'form'
    	                    , target: 'iframe'
    	            });
    	            
    	   
            var params = new Object();
            
            var g = Ext.create("Gnt.panel.Gantt", {
                height: '100%',
                width: '99%',
                renderTo: Ext.getBody(),
                leftLabelField: 'Name',
                loadMask: true,
                startDate: start,
                endDate: end,
                multiSelect : true,
                cascadeChanges : true,
                viewPreset: 'weekAndDayLetter',
                recalculateParents: false,
               
    		   tbar: [{
                    	iconCls : 'icon-pdf',
                        scale : 'large', 
                        text : 'Export to PDF',
                        handler : function(button, event){
                    	   //code goes here
                    	   Ext.Ajax.request({
                    		   url: 'task/GetTaskReportPDF.action',
                    		   params: params,
                               form: App.downloadForm,
                               isUpload: true,
                    		  // method: 'POST',                			   
    	                		success : function(response, option){
    	                			//this.gestioneRisposta(response);
    	                		      console.log("success");
    	                		}
    	                		,failure :function(response, option){
    	                			console.log("failure");
    	                		}
    	                		,scope : this
                    		});                	  
                      }
                    }
                ]
            });
        }
    };
    I am using Java as my server side technology and for the report i am using Jasper Report.

    hi.. forum member.

    I am able to get my download window that download the pdf file for me. But the problem is that the file name always comes as GetTaskReportPDF.action

    I tried to use exporterPDF.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, reportfileName); to give my file name but that also doesn't work.

    I got my solution by removing the inline from the header.

    got a solution by changing the response header as

    response.setHeader("Content-disposition",
    "attachment; filename=\"" +"example.pdf" +"\"");

    thanks for your support forum members.

    @Animal, maybe because sending params is the problem in that case. Otherwise I think thats a nice solution, less code.
