java.lang.IllegalArgumentException 错误
自己在学习jstl的时候出现了一个蛮低级的错误。
jsp中的代码：
<body> <h3>测试jstl. </h3> <hr> <a href="el.do">测试EL表达式</a><br> </body>
<struts-config><action-mappings><action path="/el"type="com.tangjian.action.ElAction"scope="request"><forward name="success" path="el.jsp"/></action></action-mappings></struts-config>
