Question

jsp使用<%%>和<%=%>报错，求大神解决

Error processing component tag. currentComponent [JspIncludeComponentModel (8796096889916@1)] exception: javax.servlet.ServletException: javax.servlet.jsp.JspException: org.apache.jasper.JasperException: /WEB-INF/views/responsive/pages/cart/cartDisplay.jsp (line: 114, column: 2) Scripting elements ( <%!, <jsp:declaration, <%=, <jsp:expression, <%, <jsp:scriptlet ) are disallowed here.

Answer 1

<%%>标签内只能输入java代码，但是jsp标签解析之后，其实就是字符串，不属于java程序范畴，所以回报错，望采纳~~~

追问

我是写的java代码的，但报错是说不能使用,这是为什么，是少jar包还是怎么回事啊
