replace it with JSTL Tags

• 首先检查，library里面有jsp.jstl 和jsp.jstl-api 这两个jar文件，如图：

• 检查完之后修改list-students.jsp 代码如下：

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>




    
    
    



    

        

            
FooBar University
        
    
    

        

            
                
                    

                

                    
First Name
                    
Last Name
                    
Email
                
                

                        
 ${tempStudent.firstName}
                        
 ${tempStudent.lastName}
                        
 ${tempStudent.email}
