------------------------------------------------------------------------------<br><STRONG> 数字签名</STRONG>
<P>用Applet写的java小程序如果没有经过签名，那么访问客户端程序下载后会受到安全限制；怎样对java小程序签名受到很多人的关注，网上也有这些方面可供参考的文档，但都不是完整，在这里我给出一份可具体操作的文档，希望能给大家一些帮助。</P>
<P> 场景：test.jar：内含待签名的java小程序</P>
<P> 结果：签名后，客户端能自动下载java小程序，且java小程序能访问客户端的任何资源</P>
<P> <STRONG>步骤：</STRONG></P>
