Installing Sun (Oracle) JDK 1.5 on an EC2 instance

Wed, 16 Nov 2011 11:52:55 +0000

I’m currently working on moving a Tomcat-based application into EC2. The code was written for Java 5.0. While Java 6 would probably work, I’d like to keep everything as “same” as possible, since EC2 presents its own challenges. I spun up a couple of t1.micro instances and copied everything over, including the Java 5 JDK, jdk-1_5_0_22-linux-amd64.rpm. Installing from RPM was easy, but the EC2 instance defaults to using OpenJDK 1.6:

[root@ec2 ~]# java -version
java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.10) (amazon-52.1.9.10.40.amzn1-x86_64)
OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode)

There were a couple of things I had to do to get the system to accept the Sun JDK as its “real” java.

64-bit Firefox 6 on CentOS 6 x86_64 (or Fedora) with Flash 11

So I’ve gone back to Linux from Mac, due to the SSD issues I had with my Macbook Pro basically making VMware unusable. A Win7 VM would grind the guest and host to a halt on the 7200 RPM SATA OEM drive, and the SSD wouldn’t work, so I put the SSD back in my HP and installed CentOS 6 x86_64. Not really ideal, but at least it works.

CentOS 6 ships with Firefox 3.6.9, which is really old by now. Fine for a server, but I wanted FF6. I grabbed the Firefox 6.0.1 bz2 from VoxCast, unzipped it and copied it to /usr/lib64/firefox-6. Then I ran yum remove firefox to remove 3.6.9 and avoid any issues. I tried the instructions from my older post on this subject but for whatever reason it didn’t work - I’m guessing because I’m not using the distro’s Firefox RPM.

Flash plugin on Firefox on Fedora 12 x86_64

I know I’ve been through this before because I’ve setup Fedora before and it’s working. But I just installed FC12 on my desktop at home (since my Seagate drive bricked itself a few days ago and I had to reinstall anyway) and while I finally got the Adobe Flash plugin working, it didn’t have any audio, which made YouTube kind of suck. Anyway, this of course was a solved problem, I just forgot where the fix was located… but duh, it’s on the Fedora website. A simple
