I tried above steps and still errors were there in JSP even runtime libraries were configured properly. I'm using java 8 and tomcat 8. So I unchecked "validate jsp fragments" under project properties > validation > jsp syntax.
我尝试了上述步骤，但即使正确配置了运行时库，JSP 中仍然存在错误。我正在使用 java 8 和 tomcat 8。所以我在项目属性 > 验证 > jsp 语法下取消选中“验证 jsp 片段”。
