Can't convince Eclipse to build with non-default JRE [message #90170]

A story of two systems:

System 1

Laptop. Has two JREs installed -- 1.4.2 and 1.3.1_08.

Eclipse is configured with both JREs and 1.3.1_08 is marked default.

Project is on a shared drive and is rebuilt.

Project can be run with 1.3.1_08 JVM.

System 2

Desktop. Has two JREs installed -- 1.4.1_03 and 1.3.1_08.

Eclipse is configured with both JREs and 1.3.1_08 is marked default.

Same project from shared drive is loaded and rebuilt.

Project CANNOT be run with 1.3.1_08 JVM because class files have
incorrect major/minor numbers (meaning Project was really
built using 1.4.1_03 JRE).

How can I convince Eclipse on the Desktop system to build
the project with 1.3.1_08 JRE so that the class files will
be able to run in a 1.3.1_08 JVM?

Shouldn't the subject be can't convince Eclipse to build with the default
JRE?
In your description you state that 1.3.1_08 is always the default and is the
JRE you wish to build against?

Try:
Context menu on the project, Properties>Java Build Path>Libraries
Ensure the JRE_LIB is what you want. If not set the correct library on the
build path

Doh! You're correct! Subject should be default vs non-default.

The settings in the project are correct (i.e. the 1.3.1 JRE). I would
expect this because both systems load the project from the same (shared)
folders and this setting is stored internally within the project.

What stumps me is that one system is working the way it should, the
other isn't and I can't find anything configured differently between
the two (other than 1.4.2 vs. 1.4.1_03).

Libraries used to compile against and compliance mode are 2 different
things.
Check Window->Preferences->Compiler->Compliance and Classfiles. I suspect
that it is set to a 1.4 compliance level.

Strangely enough it was set to 1.3 compliance but was still
producing 1.4 class files. I used the "restore defaults"
options to reset it to 1.3 and it is now producing 1.3
compliant class files.

Thanks a bunch Jerome!
