Openfire Could not locate home

                Openfire 开发环境搭建时容易出现Could not locate home 异常，主要由XMPPServer.java中以下代码引起：

private void initialize() FileNotFoundException{ locateOpenfire(); ...... } private void locateOpenfire() throws FileNotFoundException{ String jiveConfigName = "conf" + File.separator + "openfire.xml";         // First, try to load it openfireHome as a system property.         if (openfireHome == null) {             String homeProperty = System.getProperty("openfireHome");             try {                 if (homeProperty != null) {                     openfireHome = verifyHome(homeProperty, jiveConfigName);                 }             }             catch (FileNotFoundException fe) {                 // Ignore.             }         }         // If we still don't have home, let's assume this is standalone         // and just look for home in a standard sub-dir location and verify         // by looking for the config file         if (openfireHome == null) {             try {                 openfireHome = verifyHome("..", jiveConfigName).getCanonicalFile();             }             catch (FileNotFoundException fe) {                 // Ignore.             }             catch (IOException ie) {                 // Ignore.             }         } ..... }
这里主要是根据系统配置来寻找Openfire的启始目录。

如查报以上错误则：

1.检查是否有用ant 编译Openfire，确保所有编译结果都在源码路径下target\openfire 这个目录。

2.检查Debug Configuration /Run Configuration 的配置中 Arguments-->VM arguments 中配置值为 -DopenfireHome=${workspace_loc:openfire_src/target/openfire}，只有配置了这个参数，在System.getProperty("openfireHome")时才不会出现null的情况。
