Oracle JDeveloper review
A default install includes an integrated WebLogic server for development and testing
The tie-in to Oracle’s broader platform is critical. The reason for Oracle’s investment in tools is to support use of its platform, including the Oracle database and Fusion middleware including the WebLogic application server. The tools themselves are free, but the server components are not. The Oracle Application Development Framework (ADF) is a commercial framework, a licence for which is included with licences for Oracle application servers.
