I'm looking for Oracle Database and management tool for developing. Something like mysql and phpmyadmin. I'm using GlassFish as a Server. Platform Windows 64-bit and free (but no code licensing requirements).
You can use Oracle SQL Developer (free, Windows/Max/Linux, widely used):
Oracle SQL Developer is a free integrated development environment that simplifies the development and management of Oracle Database. SQL Developer offers complete end-to-end development of your PL/SQL applications, a worksheet for running queries and scripts, a DBA console for managing the database, a reports interface, a complete data modeling solution, and a migration platform for moving your 3rd party databases to Oracle.
