I have a question, how I can set the path for the
OutputStream like i get it for the InputStream with
getResourceAsStream?
I'm not sure you can do that, particularly since a
resource might be inside a JAR file or be located in a
place you do not have write acess to.
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.
If you know that the properties file is in a specific
place and that it makes sense to write to it then I
would think you'd use typical file i/o and determine
the path via getRealPath.
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, "");
It confuses me why you'd want to do this in a webapp,
though. Settings you are likely to modify from within
the app should be in a database, not a properties file
(IMO, anyway).
Agreed. Or otherwise externalized, for example through JNDI or something.
