Openfire Could not locate home

                Openfire 開發環境搭建時容易出現Could not locate home 異常，主要由XMPPServer.java中以下代碼引起：

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.             }         } ..... }
這里主要是根據系統配置來尋找Openfire的啟始目錄。

如查報以上錯誤則：

1.檢查是否有用ant 編譯Openfire，確保所有編譯結果都在源碼路徑下target\openfire 這個目錄。

2.檢查Debug Configuration /Run Configuration 的配置中 Arguments-->VM arguments 中配置值為 -DopenfireHome=${workspace_loc:openfire_src/target/openfire}，只有配置了這個參數，在System.getProperty("openfireHome")時才不會出現null的情況。
