Question

我收到以下异常并且不确定问题是否在tomcat 8.0.15中，或者是否存在其他库的不兼容性：

有什么想法吗？

JDK 8u25
Tomcat 8.0.15
Spring 4.1.2
Tiles 3.0.5

Answer 1

问题解决了。另一个组件包括spring boot jar，它是一个依赖包括tomcat 7.0.54库。

Answer 2

确保tomcat / lib中存在jasper.jar。如果缺少，请添加它，如果没有，请尝试Tomcat＆gt;从Eclipse中清除...

Answer 3

也许你错过了HTTP Status 500 - java.lang.NoClassDefFoundError: Could not initialize class org.apache.jasper.el.ELContextImpl

中提到的el-api.jar 亲切的问候， soilworker

Answer 4

将servlet-api.jar，jsp-api.jar，el-api.jar添加到eclipse中的JRE系统库

Windows - 首选项 - 已安装的JRE -

选择现有的jre和cleck编辑以添加罐子。
