Method Source Code

//package com.java2s;

import java.io.IOException;

import java.util.Properties;

public class Main {
    /**/*from  ww w.  j a va 2s  . c o  m*/
     * Loads {@link Properties} using current thread's classloader. Here <i>filename</i> is supposed to be placed in
     * one of the roots which are covered by the default classpath of a webapp, e.g. <code>Webapp/WEB-INF/lib</code>,
     * <code>Webapp/WEB-INF/classes</code>, <code>Appserver/lib</code> or <code>JRE/lib</code>. If the properties file
     * is webapp-specific, best is to place it in <code>WEB-INF/classes</code>. If you're developing a project in an
     * IDE, you can also drop it in <code>src</code> folder (the project's source folder).
     * <p>
     * You can alternatively also put it somewhere outside the default classpath and add its path to the classpath of
     * the appserver. In for example Tomcat you can configure it as <code>shared.loader</code> property of
     * <code>Tomcat/conf/catalina.properties</code>.
     *
     * @param filename - properties filename
     * @return {@link Properties} object, never <code>null</code>
     * @throws IOException
