Argo UML and LinuxPPC

Argo UML and LinuxPPC

[ian reinhart geiser]

	Getting Java to work under anything but
	MacOS for me has always been a challenge.

	But I have faught with ArgoUML a Java based
	UML package now ever since Java for R5 has been
	out.

	I have gotten to the point where it fails ONLY
	because it cannot find my swing classes.

	I have tried to include the zip and jar file in
	my class path and STILL no dice.

	Has anyone gotten this to work?

	And if not does anyone know of a UML or CASE tool
	for LinuxPPC?

	I am REALLY not wanting to have to boot into MacOS
	just to use Object Plant and for some reason MOL
	just crashes and burns when I try to run it from 
	there...

	ideas?

	thanks in advance.

Ian,

I just downloaded this program myself and haven't yet worked with it. 
However, here are a few relevant facts:

- There are two current versions of Argo/UML available: 0.5.2 and 
0.7. 0.5.2 is a stable production release, 0.7 is still beta / 
pre-release.

- Version 0.5.2 requires you have JDK 1.1.x (x >= 7; JDK 1.2.x is not 
supported) and the separately installed Swing. Note, too, that you 
*must* use Swing 1.0.3 and *must not* use Swing 1.1.1. Swing 1.1.1, 
though basically an upwardly compatible upgrade in concept, cannot be 
freely substituted into Java programs written for 1.0.3 because the 
names of the packages in which the Swing classes reside was changed.

- I note that when I retrieved all the LinuxPPC Java files (both 
1.1.8 and 1.2.1) that the JDK 1.1.8 files included Swing 1.1.1 only. 
I don't believe there's anything special about Swing itself (Swing, 
per se, is 100% Pure Java, so you should be able to just go to Sun's 
JFC site and download JFC 1.1 / Swing 1.0.3 (see 
<http://java.sun.com/products/jfc/index.html>. To download this 
version, visit <http://java.sun.com/products/jfc/download-103.html>) 
and use its swingall.jar file in your CLASSPATH when running Argo/UML.

- Version 0.7 works with either JDK 1.1.x (x >= 7) or JDK 1.2.x. 
Since JDK 1.2 / JRE 1.2 include Swing, it need not be separately 
installed. If you're using JDK 1.1.x, you still need Swing 1.0.3 and 
all the previous caveats for Argo/UML v0.5.2 still apply.

As I said, I haven't worked with this software yet, so what I'm 
telling you is based on what's indicated on the Argo/UML site and my 
own knowledge of Java and Swing, such as it is. When I've had a 
chance to give some of this a try, I'll pass on any further pointers 
I come up with.

Good luck.

Hi,

The swing classes are part of the jdk 1.2.1 distribution.  If you are getting a 
"can't find metal look and feel" type error then the fault is in your X frame 
buffer server and not in the JDK.  Check out Tom Rini's latest X rpm for that 
fix and many many others.

If you are using jdk 118, then you must grab the swing classes from Sun of my 
server http://khendricks.ivey.uwo.ca and install them and add them to your 
classpath properly.

Please try that, and if you still run into problems, please send the "exact" 
error message to me and I will try to help.

I hope this does the trick,

Kevin

Ian,

Well, I've gone through the installation and configuration exercise 
for ArgoUML, version 0.70. Fortunately, I had the same problem as 
you. Fortunately? Yes, since had I not, I wouldn't have searched for 
the solution...

If you're experiencing the same problem as I had, the symptom being a 
complaint about not being able to load ...MetalLookAndFeel.class, 
then the problem is that your display is in a color mode not 
supported by the current Java and / or XF86 server and / or display 
driver. In my case, the driver is Anthony Tong's ATI Rage Pro driver 
("video=aty128fb") in 32 bit-per-pixel mode. Setting the display to 8 
bits allowed ArgoUML to start up fine (even though it made a lot of 
other things ugly--it also made everything faster, of course).

Search the LinuxPPC-User archives for specifics of the problem and 
solutions or workarounds. The following statement appears on 
<http://khendricks.ivey.uwo.ca/linuxppc/jdk/main.html>, where the 
LinuxPPC JDKs are made available:

* The current XF68_FBDev Xserver is inconsistent when specifying 
bits-per-pixel, color depth, and color masks. This causes a problem 
running JDK 1.2.X with jfc (swing) classes. A fix is available in the 
form of a source code patch for XF68_FBDev and/or a precompiled 
XF68_FBDev replacement (which needs a revised XF86Config file to 
correctly specify color depths. See the following archive to get the 
required downloads.


I hope this helps.
