如何在 Weblogic 12c 中解决 Throwable 的 ClassNotFoundException

Question

我有一个 J2EE EJB 2.0 应用程序，在 Glassfish 上运行非常完美。我刚刚完成了此应用程序 从 Glassfish 到 Weblogic 12c 的转换（Sun Glassfish 规范 XML 到 Weblogic 规范 XML）。当我将它部署到 Weblogic 12c 时，服务器日志包含以下内容：

####<Jan 27, 2015 9:50:27 AM CET> <Error> <HTTP> <MY-MACHINE> <my-server> <[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1422348627543> <BEA-101188> <A bad exception-type exists in web.xml: Throwable.

这怎么可能？如何解决丢失的Throwable？为什么在 web.xml?

我的 web.xml 以这种方式包含 Throwable：

<error-page>
    <exception-type>Throwable</exception-type>
    <location>/error.jsp</location>
</error-page>

为什么这对 Weblogic 来说是错误的？

Answer 1

在 web.xml:

中应该是这样的

<error-page>
    <exception-type>java.lang.Throwable</exception-type>
    <location>/error.jsp</location>
</error-page>
