Comment 10 for bug 410182

Ahhh this was the mysterious black screen :)

Great to see that are working your Openbravo ERP installation.

Yes, your are right the openbravo-erp-tomcat, has a difference with the standard tomcat:

The standard show in seconds that has started correctly, but in really it continues loading the contexts in background. The openbravo-erp-tomcat only shows that has started correctly when the Openbravo ERP context in completely loaded. This avoid that you start openbravo-erp and says that is successfully started and the you go to your browser and shows an error because the context is not really loaded.

If this behavior is annoying to you, you can follow this guide to not start openbravo-erp at boot time:
