Unable to compile class for JSP

[Ajit Krsna Das]

Im sorry to bother all of you but I am relatively new to JSP and I'm currently working on my school practical that requires me to create a simple .jsp file that performs a login check. The problem is I have 0 experience with creating.jsp pages but I am faced with a bad start. When I access the .jsp from the post function of my html page, im faced with this error:

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 2 in the jsp file: /login.jsp
Invalid character constant
1: <%
2: String user = request.getParameter('username');
3: String pswd = request.getParameter('password');
4:
5: if(user.equals("John") && pswd.equals("godimsohot"){

My .jsp contains a few lines as follows

<%
	String user = request.getParameter('username');
	String pswd = request.getParameter('password');
	
	if(user.equals("INFS") && pswd.equals("3202")){
		session.setAttribute("username", user);
		session.setAttribute("password", pswd);
		response.sendRedirect("Practical1HTML1.htm");
	}
	else{
		response.sendRedirect("Practical1HTML3.htm");
	}
%>

part of my html is as follows :

        <form method="POST" action="http://localhost:8081/login.jsp">
            <fieldset>
                <legend>
                    Login
                </legend>
                <label for="Username">
                    Username: 
                </label>
                <input type="text" id="username" name="username">
                <label for="Password">
                    Password: 
                </label>
                <input type="password" id="password" name="password">
                <br>
                <label id="lblError">
                </label>
                <br>
                <input type=submit value="Login" name="submit">
            </fieldset>
        </form>

One thing that jumps out is that the "if" condition is malformed.

Fixed it but the error remains

[Ankit Tripathi]

String user = request.getParameter('username');   
String pswd = request.getParameter('password');  

Try to convert single quotes into double quotes.

Hello

String user = request.getParameter('username');   
String pswd = request.getParameter('password'); 

This should be

String user = request.getParameter("username");   
String pswd = request.getParameter("password"); 

Use " " " instead of " ' " for String.

Amit
