问题
I am doing the following,
String str = "this is the new string";
URL resourceUrl = getClass().getResource("path_to_resource");
File file = new File(resourceUrl.toURI());
BufferedWriter writer = new BufferedWriter(new FileWriter(file));
writer.write(xml);
writer.close();
In the above code I am trying to write to a resource file contained in one of my java packages. After executing the code, my program executes fine but the file just updates the properties file in web-INF and not into the package where it is stored. Can anyone please help me figure how can I achieve that or what am I doing wrong here? Thanks a lot.

You should not be trying to write to a file stored with your application classes. Depending on the application server, the location you are trying to write to may not be writable or the application may be running from an application archive (a .war file).
You should use an external folder to store configuration and other application data. Typically, you specify this folder via an environment variable or a property specified during deployment.
