2.下载 unicode 和 表情 映射关系xml   
   emoji4unicode.xml  在下面的rar 中   
  
3.加入这个一个 转换类

37.                 service.close();  
38.         \}  
39.     \}  
40.   
41. \}

4.写成一个ELfunction 在jsp EL 表达式中 使用

12.         .build();  
13.     \}  
14.   
15.     **public** **static** String emoji(String arg)\{  
16.         **return** emojiFun(**null**,**null**,arg);  
17.     \}  
18.       
19.     **public** **static** String emojiFun(Integer width,Integer height,String arg)\{  
20.         **if**(width==**null**)\{  
21.             width=20;  
22.         \}  
23.         **if**(height==**null**)\{  
24.             height=20;  
25.         \}  
26.         **return** converter.convert(width.intValue(),height.intValue(),imgpath,arg);  
27.     \}  
28. \}

5;编写 tld文件
