[Puppet Users] Using Facter to find the Java version running on the machine
Hello all, I am currently trying to setup a Custom Fact that will can be used to determine the version of the Java JRE running on a machine, in order to use it in my manifests to ensure the proper JARS are distribured based on environment. I''m trying to use the java -version command and then capture the JRE release (eg "1.6.0_37"). No matter what I have tried, the output is always the full display from the Java -version command. Has anyone done this or something similar before? Any suggestions? Thanks for your time, Mike -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

This is the fact that I use Facter.add("java_version") do
setcode do
`/usr/bin/java -version
2>&1`.split("\n")[0].split(''"'')[1]
end
end

I''m trying to use the java -version command and then capture the JRE
release (eg "1.6.0_37"). No matter what I have tried, the output is
always the full display from the Java -version command. Has anyone done this or
something similar before? Any suggestions?
