I have J2SDK.1.4.2 hre is a stndard code I use:

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class check_user implements Filter
{
private FilterConfig filterConfig = null;

....


}

When I compile it says unresolved symbol: Filter. Do I need to downlaod something else also for it compile. Thanks.
