JScrollPane.VERTICAL_SCROLLBAR_ALWA YS

There's a space on your code between ALWA and YS, so I guess that may become the problem

That part is commented though isn't it? therefore it would be looked at as a comment and not cause an error?

I tried to understand what your question, but I don't know where to look for the problem. Are you talking about the 1st or the 2nd program? Both of them are the one that you're working on and have the same problems?

EDIT:
Also, please also tell us what are you trying to create?

On thinking about this again it would also be great if you could post any debug information such as the line and what error it gives?
