Hi

This is my tag handler class:
package myclasses;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.*;
import java.io.*;

public class SimpleTag1 extends SimpleTagSupport{
public void doTag() throws IOException{
getJspContext().getOut().print("Hi This is a Simple Tag example");
}
}


When I try to compile the .java class I am getting the foll: errors:
SimpleTag1.java:6: cannot resolve symbol
symbol : class SimpleTagSupport
location: class myclasses.SimpleTag1
public class SimpleTag1 extends SimpleTagSupport{
^
SimpleTag1.java:8: cannot resolve symbol
symbol : method getJspContext ()
location: class myclasses.SimpleTag1
getJspContext().getOut().print("Hi This is a Simple Tag example"
);
^
2 errors

Why am I getting this error?

Include servlet-api.jar AND jsp-api.jar in your classpath.
