New to Java

Exception in thread "main" java.lang.NoClassDefFoundError: javax/media/jai/

After I got this exception, I tried the following solution:

I downloaded the Windows package for JAI from this link:

https://jai-imageio.dev.java.net/binary-builds.html

Then I went to the Projects window > Libraries (Netbeans IDE) and browsed to the two jar files in that download. The two jar files are now showing under the Libraries node and, accordingly, they are listed in my Classpath as this:

..\..\..\Desktop\jai-imageio-1_2-pre-dr-b04-lib-windows-i586-07_Apr_2009\lib\ext\jai_imageio.jar
..\..\..\Desktop\jai-imageio-1_2-pre-dr-b04-lib-windows-i586-07_Apr_2009\lib\ext\clibwrapper_jiio.jar

There also a couple of DLL files which I wasn't sure how to add.


So why am I still getting this error? Maybe it's the wrong version of JAI?
