Importing java class to jsp causing cannot be resolved to a type error

JSP code:

    <%@ page import = "action.LoginCheckAction" %>
<%
String username = request.getParameter("username");
String password = request.getParameter("password");

    LoginCheckAction ls = new LoginCheckAction();
    ls.printSomething(username);
%>

Java class:

    package action;

public class LoginCheckAction{
    public LoginCheckAction(){
        super();
    }

    public void printSomething(String username){
        System.out.println(username);
    }
}

Another JSP file is sending post data to the JSP code posted here. I am trying to use the method available in my Java file that is located in another directory, inside the package action, however it keeps giving me a LoginCheckAction cannot be resolved to a type.

I tried importing action.* instead, and it did not work.

Can anyone please explain what the problem is?

if you have build your project using maven, sometimes it's unable to compile classes and generate the war and jar file.Build the project to eclipse or netbeans project by :-

  1. Go to the directory of the project
  2. Hold shift and right click and click on open command prompt here
  3. Type mvn eclipse:eclipse if you want to build the project for eclipse IDE or mvn netbeans:netbeans if you want to build the project for netbeans
  4. Close and open the project and your errors should be resolved

The only thing I can think off is that LoginCheckAction source code is not being compilled properly or added to the war or EAR of your web application deployment.

Try without space <%@ page import="action.LoginCheckAction" %>
