Openfire Could not locate home

Openfire 开发环境搭建时容易出现Couldnotlocatehome 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。
