✍: FYIcenter.com
If you have httpcomponents-core-4.4.6-bin.zip installed, you can follow this tutorial to run the PrintVersionInfo.java HttpComponents Core Example:
1. Open the example program file PrintVersionInfo.java from \fyicenter\httpcomponents-core-4.4.6\examples\org\apache\http\examples\ folder:
/* * ==================================================================== * Licensed to the Apache Software Foundation (ASF) under one * or more contributor license agreements. See the NOTICE file * ... */ package org.apache.http.examples; import org.apache.http.util.VersionInfo; /** * Prints version information for debugging purposes. * This can be used to verify that the correct versions of the * HttpComponent JARs are picked up from the classpath. */ public class PrintVersionInfo { /** A default list of module packages. */ private final static String[] MODULE_LIST = { "org.apache.http", // HttpCore "org.apache.http.nio", // HttpCore NIO "org.apache.http.client", // HttpClient }; /** * Prints version information. * * @param args command line arguments. Leave empty to print version * information for the default packages. Otherwise, pass * a list of packages for which to get version info. */ public static void main(String args[]) { String[] pckgs = (args.length > 0) ? args : MODULE_LIST; VersionInfo[] via = VersionInfo.loadVersionInfo(pckgs, null); System.out.println("version info for thread context classloader:"); for (int i=0; i<via.length; i++) System.out.println(via[i]); System.out.println(); // if the version information for the classloader of this class // is different from that for the thread context classloader, // there may be a problem with multiple versions in the classpath via = VersionInfo.loadVersionInfo (pckgs, PrintVersionInfo.class.getClassLoader()); System.out.println("version info for static classloader:"); for (int i=0; i<via.length; i++) System.out.println(via[i]); } }
2. Compile and run the example with Java SE 8 JDK:
\fyicenter\httpcomponents-core-4.4.6\examples>\fyicenter\jdk-1.8.0\bin\javac -cp ..\lib\httpcore-4.4.6.jar org\apache\http\examples\PrintVersionInfo.java \fyicenter\httpcomponents-core-4.4.6\examples>\fyicenter\jdk-1.8.0\bin\java -cp .;..\lib\httpcore-4.4.6.jar org.apache.http.examples.PrintVersionInfo version info for thread context classloader: VersionInfo(org.apache.http:httpcore:4.4.6)@sun.misc.Launcher$AppClassLoader@73d16e93 version info for static classloader: VersionInfo(org.apache.http:httpcore:4.4.6)@sun.misc.Launcher$AppClassLoader@73d16e93
