well I got it right with that one image, saw it in my web browser, after
taking out all of the special characters. But when I tried to do the same
thing with another img. I am afraid that I had an unpleasant return back to
the old NullPointerException!! Can you please continue to give me some help
w. this? Thanx.

I dont think you can use special characters as your filename
so ren your image to image.jpg then re-get using
logo = getServletContext().getResourceAsStream("image.jpg");

here is the entire code for the image servlet which I seem to be
repeatedly getting that NullPointerException java exception. Any ideas
what the problem is ? :
package coreservlets;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Image_File extends HttpServlet {
public void doGet( HttpServletRequest rq, HttpServletResponse rp )
throws
ServletException,
IOException {
rp.setContentType( "image/jpeg" );
ServletContext sc = getServletContext ();
InputStream in =
sc.getResourceAsStream("/Sexy_Laundry_Girl!.JPG");
int r = 0;
byte[] by = new byte[4096];
OutputStream os = rp.getOutputStream();
while( ( r = in.read(by)) != -1) {
// if (r in= null)
os.write(by, 0, r);
}
os.flush();
os.close() ;
}
}

you can always wrap your accesor in a simple try/catch block as in
try
{
Image logo=null;
logo = Toolkit.getDefaultToolkit().getImage("images/splash.png");
}
catch(NullPointerException excp)
{
log.debug("NullPointerException thrown while retreiving image
images/splash.png");
System.out.println("NullPointerException thrown while retrieving
images/splash.png");
}
Anyone else?

I know that this question of mine has been asked/answered in this
group, but I was wondering how do I go about checking for a null value?
I feel the need to do this in a servlet file that incorporates an image
into it.
