MYPROJECTROOT/.settings/org.eclipse.jst.common.project.facet .core.prefs
contains:

#Mon Jan 26 17:05:44 CET 2009
classpath.helper/org.eclipse.jdt.launching.JRE_CONTAINER\:\: org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType\:\ :java-6-sun-1.6.0.07/owners=jst.java\:6.0
eclipse.preferences.version=1

In "Window / Preferences / Java / Installed JREs" I have the JRE Name
"java-6-sun-1.6.0.07" as seen in the above file. But it's not likely that
every other developers JRE will be named the same.

What is the best thing I can do before I check in my project (including
classpath , .project and .settings/* ) to make it as easy as possible for
someone else to check out and run it? What happens if someone checks it
out but the named JRE does not exist? (i.e. how much will Eclipse help
out?)

Should I write some instructions that the developer should rename or
duplicate their JRE for Java 6 from Sun. And give them a name to use. So
that they can do it before checking out the project.

Some advice would be much appreciated!

Best regards, Kent

Can't you just select an Execution Environment instead of a particular
JRE? I don't know what WTP does with it, but that is how I always
configure "plain old" Java projects to avoid this problem.

Hope this helps,
Eric

I would recommend coming to an agreement within your team on what to call
external resources that are referenced in your project metadata. The name
of the JRE runtime is one such resource, but you also have the app server
runtime name, and maybe even some path variables for locating external
jars.

Hope this helps,
