I need to demo a xml based data interchange system. It is demoed offline on a trusted computer at school. The application will get database later but just for this presentation I only need to show the layout, opening and saving of xml-files and how the table gets data from the xml.

So, what would be the best location to let the web app create the xml files temporarily so I can showcase this app? I'm using Eclipse and Tomcat.

As mentioned, security is not an issue at all, since this version is NOT going to be online. Also, it's ok if the files get erased each time the application is run.

They need to exist only for the duration of the presentation where the application is run once. So, I'm clueless what would be the best location and how to get the path to such location not depending on the computer used.

Thank you.

Use the property java.io.tmpdir to get the tomcat temp folder and save your files there. That will be a good place to temporarily keep them in. So you can define it as follows:

public static final String TMP_DIR = System.getProperty("java.io.tmpdir")
