24 24  A first experience with FrontBase, WO 5.3.1 and MacOSX 10.4.6
25 25  
26 26  Make sure you have the FrontBase jdbc connector accessible from your WebObjects applications. I placed mine in /Library/Java/Extensions/
27 27  Make sure that the FrontBasePlugIn.framework is located in /Library/Java/Frameworks
28 28  Make sure that you have added the framework to your project or you will not be able to establish a connection to your database, even though you'll be able to see your database from EOModeler.
29 -If you haven't yet assigned a User/Password combination to your database, you still must include User information in order for the connection to be established. Use system to get started. The URL for basic connection is: jdbc:FrontBase:~/~/localhost/my_database_name

31 31  The documentation available at the Frontbase site is very complete. The only gotcha was that I was left with the impression the framework was only necessary for WebObjects 4.5 and below. This is not the case, you have to install and include it for WO 5 projects too.
