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/' ...

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 org.eclipse.jdt.core.dom.ASTParser.createASTs(ASTParser.java:970)

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

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

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
