- From a servlet, you'll want to to:
URL url =
getServletContext().getResource("/WEB-INF/properties/xyz.txt");
If you don't have access to any of the servlet API objects, you might
have to move your properties file into the WEB-INF/classes/ directory,
or into a JAR file in the WEB-INF/lib/ directory. Then you can do this:
URL url =
Thread.currentThread().getContextClassLoader().getResource("/xyz.txt");
Then do whatever you want with that URL. For example:
Properties props = new Properties();
try(InputStream in = url.openStream()) {
props.load(in);
}
// Now use your properties
Hope that helps,
