Eclipse Requires JRE5 But I have JRE6

I have installed Eclipse 3.5.1 and Java for Developers JRE6 (java version "1.6.0_20") on f12x86_64.
The website for Eclipse states they prefer the use of JRE5 (java version "1.5.0_11") as it is tested to be compatible.

Will I experience any issues by using JRE6 with Eclipse?

If I install JRE5, how do I prevent yum update updating to the latest?

I am not sure about issues regarding JRE with Eclipse, but to prevent yum from updating a package you can add the line:

in /etc/yum.conf.

Hope this helps,

Yum does not update Sun (Oracle) Java (if that's what you have installed) because it's not in any Fedora/third party repositories. You'll have to manage the updates yourself. As far as the version is concerned, it should work fine with both. In fact, multiple JREs installations can coexist on the same machine. Java for developers is actually the SDK, so you may want to install that instead

Re: Eclipse Requires JRE5 But I have JRE6

There are subtle issues with different JVMs that you'll eventually run into. Consider your target platform. If you are developing for a platform that runs only JDK5 and below you'll get into trouble at deployment/install time. Also consider your team. If your team doesn't all run the same JDK you'll have constant conflicts and the "it works on my machine" classic problem. If you're just a lone guy developing something for yourself then you should be just fine with Eclipse and JDK6.
:eek: Holla' at me... :cool:
