servlet package not found in my JDK 7 update 2
===

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

i have a source code containing the above imports and i run into a lot of error messages as the servlet package is not included in my installed JDK 7 update 2.

i am really confused and don't know why, Thank you a lot for any guide to fix my tiny issue.
