This is a regression after jdk1.4.2_03, and it is restricted to the linux platform only; I've verified that it works fine on Solaris.
I've attached the user's apps in attachment.

From the error trace, the problem occurs in the native code.

In getViewManager
/home/cyang/Linux/j2sdk1.5.0/jre/lib/i386/libJ3D.so: libmawt.so: cannot open sha
red object file: No such file or directory
java.lang.UnsatisfiedLinkError: /home/cyang/Linux/j2sdk1.5.0/jre/lib/i386/libJ3D

Here is the steps to run the apps :

1) Unzip the JARs into a directory on your disk.

2) From that directory, run:

In jdk1.4.2, a map windows will appear, but not in jdk1.5.0beta


Here is the customer's email :

Hello, my name is John McCormick and I have been involved in the development
and implementation of the IDV (Integrated Data Viewer) which is written in
java and utilizes J3D packages (for 3-D viewing).... (For more information on
IDV, refer to the following URL):

http://my.unidata.ucar.edu/content/software/IDV/index.html

I had installed the J3D version quite successfully on the linux platform for
the following Java versions :

(1) Java 1.3.1_02
(2) Java 1.4.1_05
(3) Java 1.4.2

The IDV software ran fine and displayed various (gridded) datasets fine with
the 3-D features as well. However, for the Java 1.5 version, I downloaded
and installed the J3D in the same way and the normal (map) window did not
come up at all --- (which usually is displayed running the previous java
versions)...

I realize that Java 1.5 is a Beta-version but I just wanted somebody on the
"inside" of the J3D operation to know about this problem... I would like to
know one or more of the following:

(1) Is there is another J3D (installation download program) version out
specifically for the Java 1.5 ?

(2) Is there something you can tell me (about the new Java 1.5) that might be
a "bug" causing this (map) window not to appear?

(3) Since I've run J3D successfully with IDV (Integrated Data Viewer) using
other Java versions successfully, I'm pretty sure that it's not a problem
with the IDV code.

I'd appreciate it if you would respond and let me know anything that you can
find anything that may, perhaps, shed some "light" on this problem.

Thank You,

John McCormick
