初学getProperty 求解答~
getProperty标签是不是按顺序在各种scope里找Bean的属性?
为何我这么写不对呢？MyZQB是一个Bean类。s是MyZQB的一个属性。
- HTML code
省略。。。<body> <% pageContext.setAttribute("MyBean", new MyZQB("yy")); %> <jsp:getProperty property="s" name="MyBean" /></body>省略。。。异常：
严重: Servlet.service() for servlet [jsp] in context with path [/Beer] threw exception [file:/Test.jsp(22,1) jsp:getProperty for bean with name 'MyBean'. Name was not previously introduced as per JSP.5.3] with root cause
org.apache.jasper.JasperException: file:/Test.jsp(22,1) jsp:getProperty for bean with name 'MyBean'. Name was not previously introduced as per JSP.5.3
