I installed XUbuntu a few days ago. And I installed Java 64bit. I found that I have to install 32bit version to use webstart. I read the install instructions at the sun homepage and did exactly what they say. After I accept the license agreement I see the following:
Unpacking...
Checksumming...
0
0
Extracting...
./jre.bin: 310: ./install.sfx.4745: not found
Done.
The number 4745 is not always the same (e.g. had 4850 before). After that I can see a new dir but it is empty. And if I try to delete it I get "it is not empty".
I used "sudo find -name javaws" to find the webstart file. It did not find it.
I hope someone understand me and will help. Or I will write it in German }:-@
