Answer 1

RSyntaxTextArea

RSyntaxTextArea is a syntax highlighting text component for Java Swing. It extends JTextComponent so it integrates completely with the standard javax.swing.text package. It is fast and efficient, and can be used in any application that needs to edit or view source code.

RSyntaxTextArea was originally part of the RText programmer's text editor, but is currently being made into a separate component, reusable in any Swing application.

Try jEdit. It is mainly an editor written in Java and not an editor component. But perhaps you can extract the editor component from the jar file.

Just an idea.

Answer 3

Take a look at what the NetBeans Platform provides. I know that they do release components as JARfiles, but they're not available in the Maven central repo, which has kept me from using any.
