当我在websphere 8.5.5中启动应用程序时，出现了一个错误，应用程序无法启动， 我搜索了日志，得到了这个堆栈跟踪。你们知道吗

检查此链接。您的WEB-INF/lib中可能有servlet/jsp相关的JAR。尝试删除它们并再次测试。

但我如何知道导致问题的jar？？因为我在应用程序库中有很多JAR？首先，请删除所有包含javax.servlet.*、javax.el.*包的JAR。您可以在问题中添加带有JAR的列表。不幸的是，当您使用maven并创建糟糕的pom文件时，不考虑JavaEE服务器提供的LIB，而不仅仅是像Tomcat这样的普通web容器。我从共享库文件夹中删除了el-api-2.2.jar，一切正常，似乎“el-api-2.2.jar”和“javax.j2ee.el.jar”之间存在冲突，其中“javax.j2ee.el”是应用服务器jar。现在一切正常，但我担心这可能会导致错误！谢谢
