关于openfire:请问我们自己写的插件放入openfire服务器后,程序怎么去调用写的那插件里面的功能

如果你是插件的形式开发功能，需在plugin.xml里填写你的类文件以及插件名称，并且在完成你追加的功能后，如果你不是编译运行的openfire，使用ant打包生成jar文件置于openfire根目录的plugins文件夹里

实例挺简单的，已经配置好环境

服务端先装openfire，配置好数据库，建几个用户

然后装spark，可以登录，进去后可以添加好友和进行回话

然后安装这个客户端APP，更改服务器IP，可以进行登录。

只是运行起来有点卡

步骤如下

1.使用coherence3.3+openfire3.7.1+clustering.jar1.2.0

2.将coherence3.3中的三个jar包coherence.jar+coherence-work.jar+tangosol.jar拷贝到openfire的安装目录的lib下

3.将clustering.jar拷贝到openfire的安装目录下的插件plugin包中

4.重启服务，登陆到web管理控制台，在clustering目录下设置enable

5.再重启服务，登陆管理控制台时，初始化错误异常

起初怀疑是coherence与openfire的版本不兼容，之后试了coherence3.7.1，coherence3.6.1，coherence3.5，coherence3.4与openfire3.7.1、openfire3.6.4的各种排列组合

均报异常。
