我目前正在尝试让 Worklight Application Center 在新安装的 Worklight v6 上运行，该安装在 WebSphere Application Server v8 和 WebSphere Portal v8 上运行。这看起来很简单，IBM Installation Manager 根本没有抱怨。我什至可以在安装完成后登录应用程序中心。但是，该页面显示 HTTP 500 错误，并且所有选项都“灰显”。这也可以防止再次注销。
在 WAS 日志中，当页面出错时会发生以下错误：

我已经搜索了我能想到的所有此错误的组合，但到目前为止似乎没有任何解决方案实际上适用。触发错误的 jar，“ilwwcm-eventlog-jpa.jar”，似乎是 Portal 的库存库。为了排除故障，我什至尝试解压缩库存 JAR，将引用的 xml 文件更改为“1.0”而不是“2.0”，重新打包 JAR，然后尝试一下。这只会导致 WAS 在同一文件中的不同 XML 标记上引发异常。
任何人都看到了这个，或者对如何解决它有任何想法？
