上面有两张Spark客户端的聊天室列表占有者一列不同的原因：当使用以下代码获取时不能获取occupantsCount和subject的值：

view plain

1. System.out.println(roomInfo.getOccupantsCount() + \ + roomInfo.getSubject(

));

这是由于Openfire端有个bug（暂且这样说吧，我不知为什么Openfire这样做）.首先修改Smack的一个bug,修改RoomInfo类的RoomInfo(DiscoverInfo info) 方法:

view plain

1. Iterator values = form.getField(\).getValues(); 2. if (values.hasNext()) {

3. this.subject = values.next(); 4. } 5. else {

6. this.subject = \;

7. }

改为：

view plain

1. final FormField subjField = form.getField(\); 2. this.subject = subjField == null ? \ : subjField.getValues().next();

修改Openfire的源码，org/jivesoftware/openfire/muc/spi/MultiUserChatServiceImpl类的public DataForm getExtendedInfo(String name, String node, JID senderJID) 方法：

view plain

1. /*final FormField fieldOcc = dataForm.addField(); */ 2. fieldSubj.setVariable(\);

3. fieldSubj.setLabel(LocaleUtils.getLocalizedString(\

nts\));

4. fieldSubj.addValue(Integer.toString(room.getOccupantsCount())); 5.

改为：

view plain

1. final FormField fieldOccu= dataForm.addField()； 2. fieldOccu.setVariable(\);

3. fieldOccu.setLabel(LocaleUtils.getLocalizedString(\)); 4. fieldOccu.addValue(Integer.toString(room.getOccupantsCount()));
