Hi Alexandre Thank's for your help. It works good and it is simple.
For you, or others interested. We have made a eclipse plugin for Ojb for our project, but it can be use for any ojb project. http://compiere-mfgscm.sourceforge.net/ Code generation and xml file generation is done using code from ojb project. Any feedback welcome. We have also realised a Jini service for Ojb but we are waiting for license change in Sun rio/jini project. Ojb is a nice tool to work with. Thank's to all the team and it's supporters.
