JDeveloper - Checking jar libraries into CVS as part of project!?

[TDOR]

I have a problem preserving the library path in a Jdeveloper
project when checking in and checking out of CVS.

I add a jar library to a project in one Jdeveloper installtion
, check the project into CVS. Then I check the project out in
another Jdeveloper installation (on another pc). The library now
shows red in the library list on the second pc, and if I check the
path in Jdeveloper then its now empty! In the project file *.jpr the
path is still the same as on the original pc that I checked in from.

The library jar file is stored in the project <rootfolder>/lib
and is checked into cvs as well. Given the path in .jpr is
relative from the project root I dont understand why jdeveloper
shows the library as missing??

btw. im using jdeveloper 10g (9.0.5.2). The library is added to
the project as a "user library".

Any1 knows whats going on??
