Forms Conversion [3.2] Enables the loading of Oracle Forms source into an OracleApplication Express project and generate an initial APEXapplication.

InteractiveReports [3.1] An innovative new technology that allows end users tocustomize reports. By putting more power in the hands of users it reduces development

time and effort while simultaneously enhancing application functionality.

Web Services Integration [3.1] Ability to easily integrate with services through eitherbuilt-in Web service support or through lower level PL/SQL UTL_HTTP package calls.

Optional Runtime-Only Deployment [3.1] Ability to install just a runtime APEXenvironment via SQL scripts for production environments, minimizing installed footprint and

increasing security.

PDFPrinting [3.0] Integrate with Report Server (Oracle BI Publisher, Apache FOP,orXSL-FO) to produce PDF, XLS, HTML outputs. Can define multiple report queries and

load custom RTF orXSL-FO templates.

Flash Charts [3.0] Create professional charts using Adobe Flash
