Retrive values from an arraylist and display in a jsp?

Hi,

I need help in jsp to display values of an ArrayList in jsp.

There is a java file containing a method which is returning an ArrayList.

I want to display the records of the ArrayList in jsp in a tabular form/way.

if (request.getParameter("action") != null) { Open connection to the database; Read parameters from the JSP formular (parameters are NAME and YEAR of each student); stmt.executeUpdate("insert into Students(name,year) values('"+name+"', '"+year+"')"); Close the connection;

ArrayList<Student> students = StudentsManager.getInstance().getStudents();
    %>
    <html>
    <body bgcolor=#4AA02C>
    <center>
        <h2>Student list</h2>
        <table border="1" cellspacing="1" cellpadding="8" bgcolor= #EBDDE2> 
        <tr>
            <td bgcolor= #FF9966><b>ID</b></td>
            <td bgcolor= #FF9966><b>Name</b></td>
            <td bgcolor= #FF9966><b>Year</b></td>
        </tr>
            <%
            int no = 1;
            Student s = students.get(no); 
            %>
            <tr>
              <td><%= no %></td>
              <td><%= s.getName();%></td>
              <td><%= s.getYear();%></td>
            </tr>
            <%
            no++;
}

%>

(First RED X)<%}else{%>

   <jsp:forward page = "Student.jsp"/> // Student.jsp is the form where name and year of a student 
                                                       //    is requested to be entered to the database
(2nd RED X)  <%>}%>

1st red X: syntax error on token â?želseâ??, finally expected.

2nd red X: Multiple annotations found at this line: -syntax error on token â?žcatchâ??, Identifier expected - syntax error on token â?ž}â??, delete this token - syntax error on token â?ž>â??, delete this token
