What is "jdeveloper"

JDeveloper is a freeware IDE supplied by Oracle Corporation. It offers features for development in Java, XML, SQL and PL/SQL, HTML, JavaScript, BPEL and PHP. JDeveloper covers the full development lifecycle from design through coding, debugging, optimization and profiling to deploying.

With JDeveloper, Oracle has aimed to simplify application development by focusing on providing a visual and declarative approach to application development in addition to building an advanced coding-environment. Oracle JDeveloper integrates with the Oracle Application Development Framework ( Oracle ADF) - an end-to-end Java EE-based framework that further simplifies application development.

The core IDE exposes an API that other teams in Oracle use to build extensions to JDeveloper. BPEL, Portal, Business Intelligence and other components of the Oracle platform all build their design-time tools on top of JDeveloper. The same IDE platform also serves as the basis of another Oracle product, SQL Developer, which Oracle Corporation promotes specifically to PL/SQL- and database-developers.
