Hi Fernando,

You could set the Java system property derby.system.home, or use an 
absolute path. I don't remember for sure, but I think you have to set 
derby.system.properties before you load the Derby driver.

That depends.
If you have specified derby.system.home it will be saved relative to 
that directory.
If you haven't specified the property, it will be saved relative to the 
current working directory.
If you specify an absolute path for your database, it will be saved 
there. For instance, 'jdbc:derby:/tmp/myDB;create=true' would be created 
under /tmp. If you set derby.system.home to '/home/myself/databases' and 
do 'jdbc:derby:myDB;create=true', the database will be saved under 
/home/myself/databases.

I don't know Eclipse, but in NetBeans the current working directory will 
typically be /home/user/NetBeansProjects/MyProject I think.
