SQL Developer does not support Apache Derby. It only supports a very limited (and fixed) set of DBMS as documented on the WebSite:

• Oracle (obviously)
• MySQL (obviously)
• SQL Server
• DB2
• MS Access
• Sybase
• Teradata

(All third party DBMS are listed as "read-only" on the website - whatever that means)

You will need a "real" general purpose JDBC client to use it against Derby like Squirrel, DbVisualizer or SQL Workbench/J.
