I just installed Fedora 17. I'm setting up the Android Build Environment and need Java.

I downloaded and installed jdk-6u32-linux-amd64.rpm I ran

java -version

and it spit out the correct version.

Well a day or two later i tried my first compile in Fedora 17 and it complained about java and failed. I ran java -version again and low and behold it spits out

$ java -version
java version "1.7.0_03-icedtea"
OpenJDK Runtime Environment (fedora-2.1.fc17.7-x86_64)
OpenJDK 64-Bit Server VM (build 22.0-b10, mixed mode)

I'm stumped. I mean, i've run the update/upgrade commands since i installed but i didn't think that updated full version revisions... So, I ran

alternatives --config java

and that only gave me the java 1.7 version.

While digging around more I discovered that the recommended version of Java for the build environment is jdk-6u27-linux-x64-rpm.bin so I downloaded that from here: Oracle Download

When I ran:

sudo sh jdk-6u27-linux-x64-rpm.bin

it returned:

Done.

so now I'm confused. I ran:

alternatives --config java

again but it's still only returning 1.7 so I don't know what to do.I want to end up with 6u27 as the installed and functional version of the JDK. Thank you.
