平台：Win7 32bit、Netbeans 7.1.2、JDK 7、JRE 1.7.0_05。
Web 服务器：Ubuntu/Apache 和 Windows Server 2008/IIS 7。
我有一个大型 Java Web 小程序，在运行本地文件系统时运行良好，但在运行时失败http（两台服务器都经过测试）。我使用过 APPLET、OBJECT 和 deployJava.js。我一开始只是一个 APPLET，但现在我使用的是 Jave Web Start。
Experimentaion 表明，该问题仅发生在大约 34k 或更大的 JAR 中。当前版本使用通过 APPLET 标记调用的 JWS Applet。
所有 JARS 都已签名。
启用了 JAVA 缓存（以规避错误的“代码未签名”错误），但我在每次测试时清除了缓存网络。

如您所见，处理在 34440 字节后停止，但 JAR 的长度为 62791 字节！
任何地方都不会产生错误或异常（我可以看到）。
我在这个问题上花了一个星期的时间，除了增加我的知识外，尽管尝试了许多变化，但我没有得到任何结果。有人有什么好主意吗？
非常感谢期待
克里斯
