有关APPLET的问题,望高手帮忙~~~~
我用ECLIPSE写了一个APPLET程序,用ECLIPSE和Appletviewer运行都没问题,但直接运行HTML文件就无法运行.JAVA控制台显示

java.lang.ExceptionInInitializerError

貌似是无法访问本地资源,但我打包也试过了还是解决不了问题.
HTML文件:
<HTML>
<TITLE> GAME </TITLE>

<applet   archive=   "applet.jar "
                code= "appletGame.class   "
                codebase= ". "
                width=720   height=576>

</applet>
</HTML>  

JAVA程序太长了,我是想把原来在WINDOWS下运行的拼图游戏移植到网页里.望了解情况的高手指点啊~~~~



------解决方案--------------------
applet不能访问本地资源,你可能是读取了本地IO资源。

如果要访问的话,需要通过证书认证。可以自己生成一个,然后让用户通过执行。
------解决方案--------------------
在机器主目录创建.java.policy文件:
grant{
permission java.io.FilePermission "image/0.jpg ", "read ";
};
如果还有其他Caused by: java.security.AccessControlException: access denied (java.io.FilePermission image/0.jpg read)
错误,请添加相似的策略项
