One solution is to split the context path by the delimiter File.separator, then remove the last path element. Finally concatenate the result with "uploadedFiles/"+Name;

If you want to save the files outside of the web context (which I agree is the correct way to do this) then you won't be able to directly access them, because they're not in context.
However the problem is easily solved, you provide a file download servlet which reads the file from the directory, and sends it out as a servlet response.

I would set it up such that http://myWebSite/myWebApp/getFile/MyFile.txt would download the file.

A servlet mapping in web.xml would map /getFile/* to the file servlet
The servlet would then look at the rest of the url to know which file to send back to the client.

Googling for "file servlet" gives you some good results.

Dear Stefan i think your solution works but i am new to jsp so as requested by you i cannot perform task so please can you give me step by step to perform these task

A "getFile" servlet, that serves a file outside of the context root, basically follows these steps:

Servlet receives request for file

Servlet opens file as input stream

So far so good? Send the appropriate content type & length via HttpServletResponse

(if there was an error, send your error message & quit)

Use the response's getOutputStream() method to get your output stream

Chunk by chunk, read from the file, write to the output stream

Close input stream

Flush & close the output stream

One security caution - use a context-param or a protected field in your servlet to store the base directory where these files will live, and only serve files from that base directory. DO NOT let this servlet serve just any file on your system, or you may allow people to access /etc/password or file:///C|/WINDOWS/ntusers.dat , or other sensitive files that you probably don't want to share.

Dear Pete Nelson,Does input stream works on image file also the file uploaded may be image or text extension or any extension.Can you give me examples how to follow these steps in general

Input Stream deals with a stream of bytes. It doesn't matter if the bytes are ASCII text or binary data.

As far as examples, there are a TON on the web waiting for you to google. Try googling for "java file io", or even "file servlet", as Stefan Evans suggested.
