Yup, there's no guarantee that the contents of a webapp can be written
to in all deployment contexts. However, as long as you know you will be
deploying it to a container that allows the file to be written to, you
should be OK.

In your case, a simple change to the code you've already written should
do the trick. Something like this (untested):

  URL res = Thread.currentThread()
     .getContextClassLoader()
     .getResource(pathToConfigurationFile);

  InputStream input = new FileInputStream(res);

  //Load the properties
  properties.load(input);
  input.close();

  ...

  // Save the properties
  OutputStream out = new FileOutputStream(res);
  properties.store(out, "");

Agreed. Or otherwise externalized, for example through JNDI or something.
