This is good but there some javascript which helps me to select multiple files in the "File upload dialogbox" e. I am sure you are able to find that easily. Google is a nice friend.

Moreover, if you want some easy template for it, you can always go to some javascript libraries or frameworks, like jQuery, Mootool MemoryLeak MemoryLeak 7, 22 22 gold badges 82 82 silver badges bronze badges.

I don't want to create seperate input tag for each file. Say I want to upload 10 files, i need to create 10 input tag. To eliminate these situations, I mention clearly " selecting multiple files in same dialog box " in my question. I used that before, it is very conveninent — MemoryLeak.

Inside the scriptlet call the isMultipartContent method of class ServletFileUpload which takes one parameter request.

This method checks whether there is a file upload request or not. It returns the boolean value. The implementation of FileItemFactory means that it creates FileItem instances which keep their content either in memory or disk. While using the DiskFileItemFactory the temporary files are automatically deleted as soon as they are no longer needed. This is used to constructs an instance of this class which uses the supplied factory to create FileItem instances.

Now declare a variable of type List with the initial value null. Use the method parseRequest and pass a request object as its parameter which returns a list of FileItem instances parsed from the request, in the order they were transmitted.

This method will throw FileUploadException if there is any problem while reading or parsing the request. Don't worry this is not going to happen in this example. To iterate the list of FileItem instances parsed from the request use a method iterator of interface List which returns an iterator over the elements in this list in proper sequence.

To get the list of FileItem instances we need to make use of while loop This loop will continue until the end of FileItem doesn't reached.

After all this we need to save the file to the particular location. Create a object of File class of package java.
