我在eclipse中用tomcat启动webtop 6.5 sp3时出错。 DFC jar已经添加到classpath和buildpath中。访问网络应用程序进入空白页Apache Tomcat启动警告（ExceptionInInitializerError）

关于如何解决这个问题的任何想法？

这是一个警告，而不是错误。它是否阻止您的服务器加载？ – Sean

看起来像服务器负载，但访问Web应用程序显示一个空白页面。（用这个信息编辑问题） – Ayrad

只是一个猜测，但它在我看来像你缺少一个配置文件。你的类路径中有config目录吗？

这是一个很好的猜测。我已经将配置文件夹的构建路径（Windows中的CLASSPATH变量）添加到服务器启动配置中的类路径中，可能需要将其添加到其他位置。我知道这个配置文件夹因错误而出名 – Ayrad

回到5.2.5天后，我们将它添加到了Tomcat类路径中。我认为这是你的意思是服务器启动配置。鉴于在DfClient类初始化过程中发生故障，我认为它是缺少的主要Documentum配置文件，这意味着类路径对于Tomcat来说是不正确的。您应该可以使用catalina.properties中的shared.loader属性来添加所需的Documentum（dctm.jar，config等）类路径条目 –
