Derby travel db not working

Hi forum, I have a problem with the Derby server that comes with the sjsas 9, the server runs ok from the menu start->programs->Sun Microsystems->Application Server PE 9->Start JavaDB, but when I try to get a connection from NetBeans 5.5 Runtime,Databases,jdbc:derby://localhost:1527/travel, I get a message window with the text:

The application server rejected establishment of the connection. An attempt was made to access a database, travel, which was not found.

Can the root of problem be that I had the glassfish installed before the install of sjsas 9, and then I remove the first )deleting the folder of glassfish)? Or maybe it can be because I installed a sjsas 8 after the installation of sjsas 9 and don磘 remove the last?
