Helpful hint #1: When posting examples, please minimize the samples to just the parts that you think relate to the problem. It's very hard to read long bits of code and XML on-screen, and since no one here gets paid, they're not likely to want to print it off and read it.

Helpful hint #2: Java supports a "universal" file path format. Use it in preference to OS-specific forms both to assist in code portability and because it doesn't use backslashes, which are very treacherous in Java.

So instead of


Code this:


Note that as a general rule, you should not read, write, or create files within the webapp server or WAR directories. ESPECIALLY do not create, write, update or delete files inside the WAR itself. Use an external directory!

I am not sure what you mean about the path, though. If you're looking to do something with the path of the file as it is stored on the client, you should be aware that most web browsers do not send that path, with the exception of Internet Explorer. It's a security risk in that it publishes hints about the structure of the client's filesystem. Plus, since client and server cannot do actual file I/O with each other, it's useless. HTTP file upload/download doesn't do file I/O over the network. Instead it simply embeds the data contents of the file into an HTTP request or response data stream.
 
Don't get me started about those stupid light bulbs.
