Java Class PPM, PPMImage not found, where to get JAR Files

I need help and wanted to ask if somebody knows where to get the JAR Files for my s开发者_如何学运维ystem library (eclipse helios), cause I need to use those classes PPM and PPMImage but the import declarations seem not to work

package com.sun.media.imageio.plugins.pnm;


import java.awt.*;
import java.awt.image.BufferedImage;
import java.awt.image.WritableRaster;
import java.io.*;
import java.lang.*;
import com.apple.*;
import de.medieninf.ads.*;

this is what I have implemented so far

I googled this hard but couldnt find anything.

You need to install Java Advanced Image and its plugin Java Advanced Image I/O Tools: JAI 1.1.3 and JAI I/O Tools 1.1

These provide you the PNM plugins are trying to use.
