你先试试普通的Applet能够在网页中运行么。
可以的话,就是端口的问题了 .
另外有个地方有Applet的权限设置(默认Applet是不能进行网络连接的)
找到此文件,\jre6\lib\security\java.policy
修改一下就可以了。具体的设置方法自己去网上查一下
// Standard extensions get all permissions by default
grant codeBase "file:${{java.ext.dirs}}/*" {
permission java.security.AllPermission;
};
// default permissions granted to all domains
grant {
// Allows any thread to stop itself using the java.lang.Thread.stop()
// method that takes no argument.
// Note that this permission is granted by default only to remain
// backwards compatible.
// It is strongly recommended that you either remove this permission
// from this policy file or further restrict it to code sources
// that you specify, because Thread.stop() is potentially unsafe.
// See "http://java.sun.com/notes" for more information.
permission java.lang.RuntimePermission "stopThread";
// allows anyone to listen on un-privileged ports
permission java.net.SocketPermission "localhost:1024-", "listen";
// "standard" properies that can be read by anyone
permission java.util.PropertyPermission "java.version", "read";
permission java.util.PropertyPermission "java.vendor", "read";
permission java.util.PropertyPermission "java.vendor.url", "read";
permission java.util.PropertyPermission "java.class.version", "read";

};
