小程序无法从罐子装入类 [英] applet fails to load class from jar

问题描述

有些用户抱怨说，小程序不再起作用，当他们查看Java控制台他们是迎接一个java.lang.NoClassDefFoundError的和检查我的访问日志的我看到他们已经下载了包含类的jar文件，然后发出特定的类get请求。

Some users are complaining that the applet no longer works, When they view the java console they are greeted with a java.lang.noClassDefFoundError and checking my access log's I see they have downloaded the jar file that contains the class, and then issue a get request for the particular class.

不同的用户对不同类别的突破。

Different users break on different classes.

有些用户都很好。

任何想法可能导致此/解决这个问题。

Any ideas what could cause this/fix this.

我已经检查，以确保文件在他们的Java缓存，清除缓存等似乎没有任何解决这些问题。

I have checked to make sure the file is in their java cache, cleared the cache etc. nothing seems to fix them.

如果他们打一个QA网站它打破了为好。

If they hit a qa site it breaks as well.

推荐答案

将瓶在运输过程中损坏的得到，我们正在越来越从甲骨文/ BEA补丁服务器。

The jar is getting corrupted in transit, We are looking at getting patches from oracle/bea for the server.

似乎如果连接太慢（调制解调器速度），该WebLogic将通过发送一个数据包与LEN = 0的信号传输的结束。

It appears that if a connection is too slow (Modem speeds) that weblogic will signal the end of a transfer by sending a packet with len=0.

该网络将信号java的话说，下载成功完成，那么Java失败，出现java.lang.NoClassDefFoundError的。

The network will signal java saying the download completed successfully and then java fails with a java.lang.noClassDefFoundError.
