Answer 1

您可以从任何servlet使用servletConfig.getServletContext（）。getResourceAsStream（“ / WEB-INF / filename”）来获取它。

Answer 2

use javax.servlet.ServletContext.getRealPath(String)

the call

String webappBase = getServletContext().getRealPath("/");

will point you to the doc base of your webapp, this is the parent of WEB-INF

after that you can use

InputStream is = new FileInputStream(webappBase + File.separator + "WEB-INF" + 
                                            File.separator + "config.cfg");

to get your input stream

Answer 3

Or you can use:

System.getenv("CATALINA_HOME") + "/webapps/your project name/foo.cfg

Tomcat can't work without CATALINA_HOME, so we can use it without any additional config file or something else and you don't need to take with you huge ServletContext.
