            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());
        }
	}

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

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.

Why not just use a Button with an href config?

[tvanzoelen]

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