Hi, about the memroy problem, I have been working on it. The hints I can offer: - use
wisely the -Xmx option :-) I am surprised it accepted 4000m, I have never been able to get
higher than 2000 with the sun vm and 2800 with the JRockit one. Are you sure it really
uses the 4000m ? Also, I use the option without a space '-Xmx2500m' not sure if it
makes any difference ... - use the jrockit vm. It uses non contiguous memory and so is
able to reserve (and use) more memory than the sun one. - use incremental parsing: instead
of parsing the whole project in one shot, parse sub-projects each one at a time. You need
(i) to call the various parsings from the same directory so that verveinej can find the
intermediary output.mse each time it runs and add new data to it ; (ii) specify the full
classpath (-cp) of your project to verveinej each time so that it can links entities used
in one parsing to entities found in previous parsings About the first error, I had it a
few times, but did not find time to investigate where it comes from exactly. It is linked
to passing inappropriate path(s) or file(s) as parameters. In this case, try passing
/Users/ubhatti/Desktop/moosedata/Openbravo-3.0MP2.1/src/ without the
'org/openbravo/' ... nicolas PS: VJ definitely needs some ironing out. :-( -----

Objet: [Moose-dev] Need VerveineJ help
Hello,
I am running two different versions of VerveineJ and I have two
different problems:
1. When running the following command from the freshly downloaded
verveineJ
sh verveinej.sh -Xmx 2000m -
/Users/ubhatti/Desktop/moosedata/Openbravo-3.0MP2.1/src/org/openbravo/
I get:
Exception in thread "main" java.lang.IllegalStateException: invalid
environment settings
at org.eclipse.jdt.core.dom.ASTParser.getClasspath(ASTParser.java:248)

at fr.inria.verveine.extractor.java.VerveineJParser.parse(Unknown
Source)
at fr.inria.verveine.extractor.java.VerveineJParser.main(Unknown

2. When running this command on a copy of VJ downloaded in June and
running this command:
sh verveinej.sh -Xmx 4000m -
/Users/ubhatti/Desktop/moosedata/Openbravo-3.0MP2.1/src/
I get:

The second problem is about parameterizing the VM. I have tried
various parameters but its not working. I'm surely doing something
wrong here but cant figure it out.
thanx in advance,
Usman
