Question

我是IBM HTTP Server和Websphere商务的新手。我正在尝试访问我们的应用程序，但access.log文件显示"HTTP 1.1 500"状态代码。当我检查systemout.log WAS Consol时，它显示如下错误：

我检查了SEOURLMappersource课程，它位于SEO-BaseComponentLogic.jar中，已存在于wc.ear中，其他相关课程SEO存在于SEO-BaseComponentLogic-FEP.jar. 1}}

请指导我查看错误。

Answer 1

(initialization failure)表示类初始化失败。应该有Caused by解释该问题，但如果没有，请在日志中搜索SEOURLMapperSource.<clinit>以查找潜在问题。如果这也没有产生任何结果，那么将static{}块包装在try{}catch{}中以打印真正的问题（并且不要忘记将任何static ... = ...初始化移动到{{} 1}}阻止）。

Answer 2

我遇到了这个WC堆栈异常所描述的相同问题。我发现在我们的系统上，没有为wc用户设置相关jar文件的所有者/组，而是为root用户设置。因此，即使类/ jar存在，由于权限也无法读取。 chown / chgrp和重启后，此初始化异常消失了。
