Thanks for all. My problem was solved. I ask my friend to mount the file system of that "unusual" linux and run bin-file. All was good.
Java starts just fine.
2Tim:
I've looked for .tar or .tgz file on Sun website, but... There are only two files: .bin and -rpm.bin.
I've found jre1.5.0_01 in tgz in Internet. But I've wanted 1.4.2
Once again, Thanks.
