ClassCastException - Redhat 上的错误,而不是 Windows 上的错误

发布于 2024-12-08 06:15:14 字数 2704 浏览 1 评论 0原文

我的网站在 Tomcat 上运行。当我尝试访问其中一个页面进行状态检查时,它会检查特定的 JAR 文件。在 Red Hat 5 上(但不是在 Windows 上),我收到以下错误:

java.lang.ClassCastException: LoggingPasshashInfo cannot be cast to PasshashInfo

我从第三方获得了此 JAR,并且正在按原样使用它。根据 Apache 的 tatus 页面,RH 设置在 Tomcat 版本 7.0.22 和 JVM 版本 1.6.0_27-b07 上。 Windows 使用 Tomcat 7.0.19 和 JVM 1.6.0_26-b03。在尝试修复此问题的过程中,Red Hat 的 Tomcat 从 6.0.33 进行了升级。

不管怎样,我对此有点陌生,除了让设置看起来尽可能相似之外,我不知道如何解决这个问题。任何帮助都可以,如果我未能分享任何重要细节,请告诉我。重申一下,我正在使用的 JAR 是一个黑匣子。

完整错误:

I have my website running on Tomcat. When I try to access one of my pages to do a status check, it checks on a particular JAR file. On Red Hat 5, but not on Windows, I get the following error:

java.lang.ClassCastException: LoggingPasshashInfo cannot be cast to PasshashInfo

I got this JAR from a third party and am using it just as I got it. According to Apache's tatus page, the RH setup is on Tomcat version 7.0.22 and JVM version 1.6.0_27-b07. Windows is on Tomcat 7.0.19 and JVM 1.6.0_26-b03. Red Hat's Tomcat was upgraded from 6.0.33 over the course of trying to get this fixed.

Anyway, I'm a bit new at this and, aside from getting the setups to look as similar as possible, I'm not sure how to go about solving this. Any help would be fine, and if I've failed to share any important details, let me know. And just to reiterate, the JAR I'm working with is a black box.

我怀疑您在 Linux 服务器上安装了多个 jar 文件副本。这样做的结果可能是同一个 jar 被多个类加载器加载。通常相关但由不相关的类加载器加载的类不能通过强制转换进行转换。仔细检查 jar 文件的其他副本——例如,在 Tomcat 的顶级“server/lib”目录中——并删除除一个之外的所有副本。

I suspect you have more than one copy of the jar file installed on the Linux server. The result of this could be that the same jar is loaded by multiple classloaders. Classes that would normally be related, but are loaded by unrelated classloaders, are not convertible via a cast. Check carefully for other copies of the jar file -- for example, in Tomcat's top-level "server/lib" directory -- and remove all but one.
