ClassLoader.getSystemResourceAsStream not working when running on tomcat

Question

I am loading a configfile using ClassLoader.getSystemResourceAsStream. The file is placed in the src folder of my GWT application. It ends up in war/WEB-INF/classes . I copy the war folder to tomcat under webapps/MyApp . When running the application, getSystemResourceAsStream throws an exception. When running under Jetty it works fine.

Answer 1

Try:

getClass().getClassLoader().getResourceAsStream();

It will definitely work; I also had same type of problem. This question describes why you are having that problem.

Answer 2

Try getClass().getResourceAsStream() instead. You need to call this method to access the class loader for your web application. The method you're calling uses the system class loader, which I believe is only going to contain the classes for the web container itself.

Answer 3

This should work:

Thread.currentThread().getContextClassLoader().getResourceAsStream( "relative/path" );

Note that relative/path is a path relative to war/WEB-INF/classes Eg if your file is war/WEB-INF/classes/resources/my.properties then use "resources/my.properties"
