Regarding IDEs:

I have used "Borlands JBuilder 7", "Sun One Studio 4 EE & CE" and
"Oracle's JDeveloper 9i", my personal suggestion is Sun One Studio, but,
for projects related to Web Services I suggest using Oracle JDeveloper
9i.

There are some features that are excellent in SunOne Studio and some are
excellent in JDeveloper, its related to your project. Leave JBuilder.
(This is my personal suggestion, and could be wrong)

Regarding GUIs:

They will work  on windows platform  as well, however, if your project
used filesystem or things like that try to code in a way that is
acceptable to both OS. Ex: C:\Test is OK with windows but not with
Linux. However, C:/Test is acceptable to both.

Regarding Applets:

Applets execute inside browsers, older versions may cause problems but
not the OS. Say, If your applet  executes well inside Navigator and IE,
it should execute on Linux as well, (if the versions of Navigator and IE
are same)

Regarding Application Development:

For java  coders, these publishers are excellent

personally i like eclipse  too... =)

I have already try Forte, but I still like Eclipse ....:)
Eclipse doesn't use UI builder like in JBuilder or Forte.
But the IDE was friendly enough and it is free ...

You can download either an RPM or a tarball with java  SDK 1.4.1 from
the following location:

http://java.sun.com/j2se/1.4.1/download.html

You do have to set  your JAVA_HOME, PATH and CLASSPATH variables in
Linux, but the instructions provided are good.

Since I do mostly Server Side development with Java, I prefer
Eclipse. Which Desktop do you work in Gnome or KDE? You can get
Eclipse downloaded from:

http://www.eclipse.org/downloads/index.php

All you have to do is download it and untar or ungzip it into the
proper directory, set up your path and run with it. Installation
instructions are available for linux  from the eclipse  site.

I have developed standalone applications on Linux which ran
perfectly under Win32 EXCEPT --- if you have hardcoded a file path
to access a file, you might have problems. Probably best to set
them up in a .conf path somewhere.

If I am going to test an applet  with IE, I just run my Web Server on
my network and run it from another Windoz box. That way you are
testing your URL, your HTML and whether it runs in IE.

If you have the correct plugin, it should run in IE. There are
plugin compatability problems and if you are going to run an Applet,
you might want to use the AWT and JDK 1.1. This is unfortunate
since MicroSoft has truely attempted to SCREW JAVA!!!!

I have been developing Java on both Windoze for 4 years and on Linux
now for a year and using "vi" on Solaris as an editor now for a
couple of months.... Good luck with your Java/Linux development. I
love to work on Linux because "I" control the environment... And if
you develop in Java correctly, it is 100 times more secure, and is
truely portable to all platforms.
