Java upload file?

[darklydeadly]

Sorry if my question is not clear? I am trying to upload a file through webpage and process with java.
The file is browsed by user using
<h3>XML configuration file</h3>

<p>This input the XML file that contain all configuration parameter for the simulation</p><br/>
<input type="hidden" name="MAX_FILE_SIZE" value="500" />
<!--<input type="file" id="XMLinput" name="XMLinput" size="40" multiple> <br/>-->
<input type="file" id="XMLinput" name="XMLinput" size="40"> <br/>
<output id="list"></output>

How do I get the file and pass it to java ? I tried Request.getParameter("XMLinput"), but it doesn't work.
The servlet i'm using is Tomcat.

Cheers

There are plenty of results from Googling 'java servlet file upload'.
Apache has a package that is handy.

Thanks Tolls, I tried that and there was an example using com.oreilly.servlet.MultipartRequest; library, which is not installed on the computer. And since it is university comp, I can not add extra libraries to it.
What I'm looking for is a simple method to pass the file that I select at the html page into a java class like File.
Sorry, I just start dealing with java recently.

You can't download jar files (there's no such thing as 'installation' with pure Java apps)?
Then you'll have to look into how multipart requests work.
I try not to reinvent the wheel these days.
