I want to read data from a file and store data to it. If my app is effectively an axis web service, how can I access my file? With new File(String relativePath) ? Can I read a file in a jar? Write to a file in a jar?
What if I want to read/write to a file on the classpath rather than on the filesystem? Does this actually make any sense at all?
And in a class Apple in package com.foo.bar (hence com.foo.bar.Apple), what does the relative path relate to? The root of wherever folder com is? What if all of com has been jar-ed?
No matter what they say in Ohio, we're still first in flight!
Whether your class is a web service makes no difference to its I/O behavior. It's probably easiest to use paths that are relative to the context (which may be something like ".../axis"). Then you can construct absolute paths using the HttpServletRequest.getRealPath method. In Axis, you can obtain the HttpServletRequest as described here.

Yes, I've used that class in the past to create absolute paths. I wanted to ignore that because when I test out my components before deploying them as web services, they are simple apps.
Thanks for the tip anyway. Now I know there's no smart mechanism I should be using. [ October 30, 2006: Message edited by: David Brossard ]
