I''ve spent far too many hours trawling these forums trying to find a solution to this installation problem on a linux server:

" Openfire Classes Home not found. Define system property "openfireHome" or create and add the openfire_init.xml file to the classpath"

SOLUTION:

edit the file openfire_install_directory/bin/openfire (using any text editor)

insert the line "openfireHome=/install_directory/openfire" anywhere (below the JVM override comments is a good place)

eg "openfireHome=/opt/openfire"

我的解决方法：

$ vi /etc/profile
在里面加入：
export openfireHome=/opt/openfire

注销

解决思路：查看的openfire src

        String jiveConfigName = "conf" + File.separator + "openfire.xml";

            String homeProperty = System.getProperty("openfireHome");
