Scrapbook Inspection=ClassNotFoundException

[j_andrew_h]

I'm working with:
Eclipse SDK
Version: 3.4.2

I believe I have followed along exactly with the video.  I'm working through lesson 3, after setting up scrapbook.jpage when I click on Inspect under Run menu I get this message:

2+2
An exception occurred during evaluation:  java.lang.ClassNotFoundException

The only thing I can see that deviates from dextercowley's video is that he has a thing called JRE System Library in the package explorer.  I don't have any thing that is titled JRE System Library in my package explorer.  That is the only difference I can spot

Thanks

Hi. There are different "distributions" of the JRE and JDK available. You could try installing the JDK (Java Development Kit) from Sun. Good luck. Mark

You should try first select the necessary statement by mouse, then hit "inspect"

How about half the time the inspect option is disabled?  Care to weigh in on that, preferably within 6 months.  Ill wait here.

The code has to be highlighted for it to inspect that code.
Thanks to me, i got the answer.

Hi in the lesson3 when Inspect the code
Person p = new Person();
p
I do not see the maximumBooks and name created

also when I inspect

p.setName("Fred");
p

it shows the following error:

The method setName(String) is undefined for the type Person
Person p = new Person();
p.setName("Fred");
p

What should I do?
A fast reply would be helpful.
thanks
