"PrintWriter" is not recognized by eclipse

Question

I have Eclipse(Kepler) IDE and when I write the below code.

PrintWriter pw=response.getWriter();

It displays an error message saying that PrintWriter cannot be resolved to type. The import statements that I have used are as follows,

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.*;

Do I have to import some additional statements to get my PrintWriter to work? If yes then which are they?

Thanks in advance :)

Solution 1

Er, yes, you need to import java.io.PrintWriter. Or java.io.*.

Solution 2

You need to import java.io.PrintWriter.

Eclipse provides a useful shortcut to Organize Imports, Ctrl + Shift + O. By default this imports each class explicitly.

Solution 3

All you need is the following

   import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

why do you have javax.servlet.http.* and specific classes in javax.servlet.http?

@andrewcooke actually they are automatically imported by Eclipse when I define a Servlet

[andrew cooke]

that doesn't make it right.

@andrewcooke yeah I know that dude I was just saying the reason why they were there.

Bad advice! Over use of wildcard imports makes your code fragile when you attempt to recompile against new releases of Java / new class libraries.
