J2EE Tutorials: May 2013

Step 1:
Upload and Download multiple files at a time using JSP-Servlet.

for eg code

function displayTable(data)
{
$("#Uploadfile table").remove();
if(data!="null"||data!="undefind")
{
var objArray=JSON.parse(data);
var count=1; // UserName,filename,filepath,FileID,Uplodated_Datetime
var glacc="<center><table border='1'><tr align='center'><th></th><th>User Namer</th><th>file Name</th><th>File ID</th><th>Date Of uploading</th></tr>";
$.each(objArray, function(index,jsonObject){

glacc+="<tr align='center'><td id='uploadfile"+count+"' onclick='getid(this.id)'><a href='#'>download</a></td><td id='name"+count+"'>"+jsonObject.UserName+"</td><td id='filename"+count+"'>"+jsonObject.filename+"</td><td id='fileid"+count+"'>"+jsonObject.FileID+"</a></td><td>"+jsonObject.Uplodated_Datetime+"</td></tr>";
count=count+1;
});

glacc+="</table></center>";
$("#Uploadfile").append(glacc);
$("#printPage").show();

}
}

function showfile(hid)
{
var id=hid.substring(4,hid.length);
var act=$("#activity"+id).text();

var complance=$("#complance"+id).text();
complance=complance.substring(0,10);

var name=$("#name"+id).text();

//alert("name="+name+"complance="+complance+"act="+act);
waiting_effect_on();
$.ajax({ type: "Post", url: "show_uploadfile",
data:{flag:1,Username:name,activity:act,c_date:complance},
cache:false,
success : function(data){
waiting_effect_off();
alert(data);
if(data=="]")
{
msg_box('No File Avilable','A',function(result){

});
}
else
{
$("#submitDIV2").show();
displayTable(data);
}

}
});

}

Step 2:

click on Link to download file
call this function

function getid(id)
{

$.ajax({ type: "Post", url: "downloadfile",
data:{filename:filename},
cache:false,
success : function(data){
window.location.href="tempdownloadfile.jsp?backurl="+window.location.href;

}
});

}

Step 3:
write code on Downloadfile.jsp

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>

<script type="text/javascript">

function whatFile()
{
alert("1");
var url='file:///' + 'C://Users/1100lt031/Desktop/2012-White-Jaguar-XKR-S-Convertible-3Q-Front-1152x2048.jpg';
alert(url);
window.open(url,'Download');
}

function startDownload()
{
var url='http://localhost:8080/Project/Report/1368005388533/REC_ADVT_16_2013.pdf';
/* var url="file:///E:/Siddharth/Relese Statergy/Multi Level Purchase Order Release Strategy.pdf";
alert(url); */
window.open(url,'Download');

}
</script>

</head>
<body>
<input type="button" onclick="startDownload();"/>
<a href="download/VB6IP.zip">Download</a>
<a href="http://localhost:8080/Project/Multi Level Purchase Order Release Strategy.pdf">http://localhost:8080/Project/Multi Level Purchase Order Release Strategy.pdf</a>

</body>
</html>

Step 4:
Output:

Step 1:
Create JSP And Add Controls.

<input type="button" value="Upload file..." onclick="upload();">

Step 2:
Oen Uploading JSP file in Window

window.open("uploadfile.jsp","Test","width=300,height=300,scrollbars=1,resizable=1");

Step 3:

Control Add on uploadfile.jsp

Write Code On uploadfile.jsp.

Step 4:

Write Code On Servlet

boolean isMultipart = ServletFileUpload.isMultipartContent(request);

if (isMultipart) {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);

try {
List items = upload.parseRequest(request);
System.out.println("items=="+items);
Iterator iterator = items.iterator();
while (iterator.hasNext()) {
FileItem item = (FileItem) iterator.next();
System.out.println("item=="+item);
if (!item.isFormField()) {
String fileName = item.getName();
fileName=fileName;
fileName=fileName.replaceAll("\\s","");
System.out.println("fileName=="+fileName);

String root = getServletContext().getRealPath("/");
System.out.println("root=="+root);

File path = new File(root + "/Report");
File path1 = new File("E:\\Report");
System.out.println("path=="+path);

File file2 = new File("C:\\Users\\Bharat\\
workspace\\Juno Eclipse\\23.04.2013\\Project
\\WebContent\\Report");
if (!file2.exists()) {
file2.mkdir();
}

if (file2.exists()) {
File file1 = new File("C:\\Users\\Bharat\\workspace
\\Juno Eclipse\\23.04.2013\\Project
\\WebContent\\Report\\"+millisec);
if (file1.mkdir()) {
System.out.println("Directory is created!");
File uploadedFile = new File(file1 + "/" + fileName);
item.write(uploadedFile);

} else {
System.out.println("Failed to create directory!");
}
}

String fid="http://localhost:8080/Project/Report/"+millisec+"/"+fileName;
session.setAttribute("fileName", fileName);

File uploadedFile = new File(file2 + "/" + fileName);
// File uploadedFile = new File(path1 + "/" +"/"+name+"/"

System.out.println("sucess fully uploding.....");

/* if (path.exists()) {
boolean status = path.mkdirs();
}
*/

File f=new File("C:\\Users\\Bharat\\workspace
\\Juno Eclipse\\23.04.2013\\Project
\\Report\\"+millisec+"\\"+fileName);
String file_path="C:\\Users\\Bharat

try
{
con = DBManager.openDBConnection();
con.setAutoCommit(false);
st = con.createStatement();
String query = "insert into uploading_file(File,UserName,filename,filepath,FileID
,Uplodated_Datetime,activity,Compliance_date)
values ('"+f+"','"+name+"','"+fileName+"','"+file_path+"',
'"+millisec+"','"+currDate+"','"+Activity+"','"+Compliance_date+"')";
System.out.println("query = "+query);
int ack = st.executeUpdate(query);
//System.out.println("ack = "+ack);
//System.out.println("succuess with first query.");
}
catch(Exception e)
{
e.printStackTrace();
}
// out.print("sucess");
}

}
} catch (FileUploadException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}

}
else
{
System.out.println("UN sucess uploding.....");
//out.print("Not Uploading....");
}

try {
con.commit();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
