Your first real application, the Tax Forms Advisor, had only a command-line interface. The PC Repair Assistant you’re developing now should have a friendlierGUI. You’ll develop such an interface in this chapter using only Jess’s Java reflec-tion capabilities—that is, you’ll write only Jess scripts, not Java code. In the pro-cess, we’ll look at how Jess lets you develop software using the Java libraries in aniterative and interactive way. The GUI you’ll develop in this chapter will use Java’s Swing library. I’ll assume some basic knowledge of Swing (and Java GUIs in general) on your part. Youmight want to keep some documentation for the javax.swing package handy for reference. Note that you’ll be using an iterative approach to develop this GUI; you’ll see the same Jess functions presented several times with various refinements appliedeach time. The final code for the completed application is available from thisbook’s web site.
