How to install Syntax highlighting

Question

Okay, so I'm trying to get syntax highlighting for my jscrollpane, which I have been lead to use: http://ostermiller.org/syntax/
I downloaded the jar file, but I was wondering what do I have to do to start using the classes, I'm completely losses, I don't even know where to put it.

Answer 1

Well I don't know if this is the right way, but it seems to be at least going somewhere. I extracted the files of the jar file and put the all the extracted folder into the class folder of my current program. Then I tried to import the package with
import com.Ostermiller.Syntax.*;and when I complied it, it works so far.
but when I try to create an object it can not access it:
ToHTML toHTML = new ToHTML(); gets this error message,
--------------------Configuration: TEV3 - j2sdh1.4.2_13 <Default> - <Default>--------------------
C:\Program Files\Xinox Software\JCreatorV4LE\MyProjects\TEV3\src\TEV3.java:22: cannot access com.Ostermiller.Syntax.ToHTML
bad class file: C:\Program Files\Xinox Software\JCreatorV4LE\MyProjects\TEV3\classes\com\Ostermiller\Syntax\ToHTML.class
class file has wrong version 49.0, should be 48.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
ToHTML toHTML = new ToHTML();
