What's wrong with this program

I'm working on a Java program to do a slide show but I seem to have hit a snag.

The program compiles fine but when I go to try and init the applet I get a java.lang.NullPointerException in this block of code

Code:



        String images = getParameter("ImageNames");

        StringTokenizer imgTok= new StringTokenizer(images, ",");

And here's what the applet declaration looks like

Code:



<applet code=showDemo width=300 height=400> 

  <param name=NumImages value='3'>

  <param name="ImageNames" value='Img1.foo,Img2.foo,Img3.foo'> 

</applet>

Whats images in the StringTokenizer Declaration?? And are you shure it points to something?

Also does "ImageNames" referr to the paramater u declared in the applet, or is it text, if its a parameter are you sure it should be in qoutes?

Did you compile the project, not only the .java source code?(wat app are u using, or are u doing appletviewer in the command line??)

Can I see the whole code and the error text, I may be able to help you better then?
