If you are an RPG IV ILE person then this may be worth considering: to learn
java I bought Java for RPG Programmers and the associated workbook. It
teaches java comparing the similiarlies to RPGIV. It uses Eclipse IDE which
I like a lot and is similiar to wdsc. It's a bit out of date (written before
free form RPG IV which is even closer to java in syntax). But I've found it
most helpful to understand java. But, it's not a quick read: 700 plus
pages.. But, as it points out: your RPG IV ILE references manuals aren't
skinny either.. And now "learning java objects" is on my list of where to go
next.

Rick,

You'll do better learning about OO concepts before learning Java. There is
a book that I think is called "Learning Java Objects" that helped me
considerably. They way the book is structured, it presents an OO concept and
then has examples of how to do it in Java. It also uses the same example
through out the entire book which I like a lot.

Applets are not used very often. Unless you have something specific coming
up that requires them, I would not bother with them.

Java and JavaScript are two very different things. Other than sharing the
word "Java" and some syntax similarities, they don't really have anything in
common.

Subject: [WEB400] JAVA coding environment


I hope this is the best place for this post. I debated between here and
PC-Tech.

My frustration level has been reached trying to use WDSC as a JAVA
development environment. Yesterday I spent many hours trying to test a
simple 'hello world' applet that took two minutes to code. I need something
simpler.

For those of you doing JAVA development, what development environments do
you use?

Here are my needs as I think I understand them today:
1) Learn the JAVA language
2) Gain an understanding of OO concepts
3) Understand applets and the use of java script in web pages
4) Ultimately understand the role of JAVA in web services so when WDSC
builds a service I know what all the JAVA pieces are doing.
5) Possible write the web service pieces from scratch.
