replace all -<- with < ->- with >
To upload multiple images, videos we can use the following code..........
-------------------------------------------------------------------------------------------
HTML Code:
-------------------------------------------------------------------------------------------
-<- input type="file" name="Flash_Path" onkeypress="return false" / ->-
-<- input type="file" name="Image_Path" onkeypress="return false" / ->-
-<- input type="text" name="name" / ->-
-------------------------------------------------------------------------------------------
JAVA Code:

// Part One: to parse input file and other input form fields
try {

Use this method to retrieve all files and store files in specified path.
Change necessary paths as per your requirement.
The above method gives hash map for above HTML we can retrieve the input fields in the following way
in ActionServlet or action handling class use
Map hMap = -<- classname ->-.UploadCategoryImage(httpRequest);
imagePath = (String) hMap.get("Image_Path"); ---- form field(file)
flashPath = (String) hMap.get("Flash_Path"); ---- form field(file)
name= (String) hmap.get("name"); -- form field(general)
now we can store these values to store in database or for some logical usage.
