Hi, Thanks for the reply. But I have a doubt, what if user manually changes extension of some other file type (e.g. .bmp file) to .tdt/.txt type and uploads that file? In that case though the extension is correct, contents of the file are not?

Create a javax.activation.MimetypesFileTypeMap object and add your types to that object. Then call javax.activation.MimetypesFileTypeMap.getContentType(yourFileName) to get the contentType for the file on the server without relying on the browser content type setting. MimetypesFileTypeMap will return application/octet-stream as the default if it does not know the content type. You have to include the J2EE activation.jar in your classpath for this to work.
