Description of problem: There is a problem with the logic around
setting the location of JONAS_BASE for JOnAS-targeted projects.  The
JONAS_BASE should be updated at every invocation to prevent a
situation where the workspace has been relocated and Lomboz tries to
launch the application server from the old workspace location.


Version-Release number of selected component (if applicable):
eclipse-lomboz-3.0-7


How reproducible: Always.


Steps to Reproduce:
1. Create a JOnAS-targeted project in eclipse
2. Exit eclipse and move workspace, then open eclipse again with the
new workspace
3. Start JOnAS from within eclipse
  
Actual results: Eclipse will try to launch the application server from
the location of the old JONAS_BASE, in the old workspace location.


Expected results: Eclipse should recognize that a JONAS_BASE is not
available in the new workspace and should create a new one.


Additional info: The fix for this is relatively trivial.
