Finding temporary file storage in Java

Question

So I'm writing a Java application that uses Simple to store data as xml file, but it is hellishly slow with big files when it stores on a network drive compared to on a local hard drive. So I'd like to store it locally before copying it over to the desired destination.

Is there some smart way to find a temporary local file storage in Java in a system independent way?

E.g. something that returns something such as c:/temp in windows, /tmp in linux, and likewise for other platforms (such as mac). I could use application path but the problem is that the Java application is run from the network drive as well.

Try:

String path = System.getProperty("java.io.tmpdir");

See: http://java.sun.com/javase/6/docs/api/java/lang/System.html#getProperties%28%29

And to add it here for completeness sake, as wic mentioned in his comment, there's also the methods createTempFile(String prefix, String suffix) and createTempFile(String prefix, String suffix, File directory) methods from Java's File class.
