*** NEW COMPUTER BASED TRAINING FOR JBUILDER ***
We recently released a new two CD-ROM multi-media instructional program for the JBuilder product line, produced in cooperation with Referentia Systems. This series incorporates a new line of interactive, self-paced training software created specifically to increase the productivity of JBuilder users. The multimedia instructional CD is based on the one-week Borland JBuilder 4 instructor-led course, but is available at a fraction of the cost of the normal course. Topics on the CD range from getting productive with the IDE to developing multi-tier Java database applications with JBuilder 4
