Are Java apps really that portable... ?!


Hi

I have stumbled in this

http://www.archimedes.org.br/ it is a 2D CAD package built in Java for Linux, Mac and win...

Quote:
Archimedes works on GNU/Linux, Mac OS X and Windows and it only requires you have a Java Virtual Machine installed which is also a free software. This means that anything generated with Archimedes is easily recoverable and reused.

... allright...

So i get the .jar package from Sourceforge, http://sourceforge.net/projects/arqu...p.jar/download, try to run this with

Code:
$java -jar archimedes-0.8.1-setup.jar
and i get a whole gibberish about incorrect ELF library types is this normal...?

I mean. I have a JDK OpenJDK6-6.b20_1.9-1 from Arch, installed... shouldn't the Java Virtual Machine interpreter take care of the Jar Archive in a layer different from the OS ( Architecture and Glibc agnostic ? )

This creates a directory in /home/user :

[alex@iskandhar Archimedes]$ ls

and running the launching script, archimedes.sh, yelds this ...

So I guess this was made to run in 32 bits...

That version seems to be a very old one so it wouldn't surprise me if it didn't work properly on OpenJDK.
But in any case, I downloaded the archive on their homepage (latest version) and the program is a 32-bit executable, so it looks like the devs may have compiled the Java source to machine code instead of portable byte-code. So it's not Java's fault
