Applet运行问题

   今天遇到一个非常棘手的问题，事关公司项目的进度，望javaeye中高手不吝赐教。
问题如下：
  公司项目中有一个业务功能用到了applet。我把要用的class类都放入了applet.jar中，用签名工具进行了签名。我把这块功能放置在公司内部开发和测试两台服务器上部署，进行测试都没有问题。但是我部署到客户现场的测试系统就有问题。applet.jar包和签名文件都是直接copy过去的（文件一定是一致的）。
环境配置：web服务器采用了webSphere 4.*
         JDK 采用jdk1.4.2
applet.jar编译采用jdk1.5

每次运行applet.jar包程序报：
Java Plug-in 1.5.0_10
使用 JRE 版本 1.5.0_10 Java HotSpot(TM) Client VM
用户主目录 = C:\Documents and Settings\Administrator

我猜想 是不是和服务端的webSphere设置的java虚拟机的编码有问题，但是我把java虚拟机的编码设成UTF-8之后，还是一样的问题，确实找不到是啥子原因了。 

浏览器运行applet时，会把applet的jar包下载下来，谁知道浏览器把这个jar存储在什么位置不？

1、看错，应该是解析出错了吧。（编码问题），是不是包没有加对呢。如果是Applet的问题，你倒是可以参考一下这个：http://13q0.iteye.com/

我也感觉很奇怪，在不同的机器上都去调用这段程序，提示的错误也不一样，我换一台机器结果又报了另一个异常：

弄了一整天，还是没找到解决方法，按理说applet和服务器端的环境没有什么关系，为啥同样的文件放在不同的服务器上，用同一台浏览器来访问，有的能运行applet，有的不能运行applet，期待指点......
