With the industry buzzwords being Java, Java, and more Java, I wrote this article to provide insight into how you can leverage your knowledge of PowerScript and PowerBuilder to quickly learn and build Java programs. I'm going to assume that you're familiar with PowerBuilder and the OOP religion. To exploit all of Java's features, you must design and build applications in accordance with OOP techniques. Where appropriate, this article presents a syntactical comparison of the Java language and PowerScript. Essentially, both Java and PowerBuilder represent their programs as a collection of objects that communicate and interact with one another. PowerBuilder does an excellent job of hiding from you the low-level details required to assemble objects at runtime. Java on the other hand doesn't hide any details from you other than the implementation of the core libraries. T... (more)

We have a new release of EAServer - version 4.0 - which I am very excited about... Version 4.0 takes advantage of Java 2 Enterprise Edition (J2EE) version 1.3 features and also provides many enterprise-level features that concentrate on performance, reliability, and usability. Most important, this version of EAServer is OEM friendly and addresses many OEM usability concerns that partners had in the past. New Install Right out of the box you'll notice a new install that's sleek and quite powerful. The look and feel of the install is consistent throughout all the five platforms t... (more)

Java vs. PowerScript Pt. 2

In Part 1 of this article (PBDJ, Vol. 7, issue 1) I compared Java to PowerScript. We covered some of the fundamentals of Java language - identifiers, primitive data types and primitive data type wrappers - and PowerBuilder's any data type, and we began to discuss relational operators, so let's continue. Boolean Logical Operators In Java, the boolean logical operators as seen in Table 1 may look different; however, they perform the same as the AND, OR and NOT in PowerBuilder. The operator not present in PowerBuilder is the exclusive OR, XOR that returns TRUE if and only if one of... (more)

Java vs. Power - Leverage your knowledge of PowerScript to learn and build java programs quickly

In Parts I and II of this article (PBDJ, Vol. 7, issues 1, 2) I started comparing Java to PowerScript. We covered some of the fundamentals of the Java language - identifiers, primitive datatypes and wrappers - and PowerBuilder's Any datatype, operators, flow control statements and more. Object orientation is an area in which Java as a language really begins to shine. Sun Microsystems has gone to great lengths to keep Java simple and easy to learn. At the same time, Java enables developers to design and implement generic object-oriented libraries that are easy to understand and r... (more)

Auld Lang Syne...

And ther's a hand, my trusty friend, and gie's a hand o' thine. We'll tak' a cup o' kindness yet, For auld lang syne.... I can't get rid of the song - it's with me all the time. Well, the new year is here and with it comes the many new challenges we have to face. We're now in a brand-new century. Looking back at the micro revolution, we definitely have come a long way. Personal computing is no longer a hacker's hobby in some basement or garage. It's become a multibillion-dollar industry. This revolution has altered not only the business world, but also the fabric of our society. T... (more)
