General :: Jre - RHEL-5 / Getting Error Jre-6u16-x64-rpm.bin: Line 368: ./install.sfx.20520: Cannot Execute Binary File"?
Oct 22, 2009I have installed RHEL-5 on a 64-bit machine recently, and want to install java. Earlier when I did "java -version", it showed jre1.4.0. But for my application , I need jre 1.5.0 or later, so I decided to download jre1.6. I am the root user here and I downloaded the jre1.6 as rpm.bin as well as simple .bin format.
But the problem is that when I tried executing any of them, I am getting below error message :
" ./jre-6u16-linux-x64-rpm.bin: line 368: ./install.sfx.20520: cannot execute binary file"
Moreover, now when I tried "java -version", it is not showing any thing.
Could anybody suggest me how can I resolve this deadlock situation, as I need to install my other application at the earliest.
