Increase your JEE development productivity with Oracle ADF

Java EE is a standard, robust, scalable, and secure platform that forms the basis for

many of today’s enterprise applications. Java EE provides a set of specifications for

building multi-tier applications using the JavaTM language. In the past, there was a direct

correlation between the robust nature of an application to the complexity required to

achieve it. However, with the advent of the Oracle ADF framework, you are able to

provide the implementation of extremely rich Java EE applications, adhering to standard

patterns and practices with greatly reduced effort.

Additionally, the increased need for organizations to build composite applications that

utilize Service Oriented Architecture (SOA) principles has forced developers to create

applications that are extremely agile. Implementing these best practices in agile

applications usually involves writing a significant amount of infrastructure code, adding

another obstacle for developers building their first Java EE application.

In addition to providing robust, performant, and maintainable applications; Oracle

Application Development Framework also provides the best of breed infrastructure code

to implement agile SOA based applications thereby removing the effort involved in an

organization “rolling their own” and allowing a team to jump right in to adding value

versus building an infrastructure.

· Lower uptake costs and higher programmer productivity - ADF provides a large amount of declaratively configurable, ready-made implementations of all of the most common application building patterns you need to build an enterprise application on the Java EE platform, without losing the ability to leverage all the goodness of Java to extend the framework yourself when needed.

· ADF is built on industry standards, avoiding vendor lock in - ADF is built on industry standards (Java, XML, and others), that can run on any JEE application server, support building apps for any SQL92-compliant database, and has source available for supported customers.

· Supported by a major IT vendor - Support for open source products is haphazard across the entire software spectrum. With ADF when something goes wrong you can utilise the size and breadth of Oracle Corporation's own Oracle Support to provide bug workarounds and patches.

· Web 2.0 through ADF Faces RC - Users are demanding more sophisticated web interfaces given their experience with websites from organisation like Google. ADF Faces Rich Client (RC) delivers a rich set of web components that take traditional web-forms based applications to the Web 2.0 world.

· The ability to provide applications as a web-delivered service - If moving from an Oracle Forms legacy system, JDeveloper and ADF allows organisations to provide a web-delivered application, changing their systems from an internally focused application, to a publically available service.

· ADF is free if you already own OAS/WLS - For existing OAS/WLS licensed sites, ADF is free to deploy, leveraging your existing expenditure.

· Supports all phases of the application development lifecycle - JDeveloper with provisions for visual and declarative application development support, including database modeling, UML diagramming, page flow design, ADF BC component design and coding, web page WYSIWYG editors, deployment, integrated testing-profiling tools, and so forth, provides comprehensive design time support for all phases of the application lifecycle that most corporate application developers need.

· Staff retention - Are your Oracle Forms IT staff leaving after getting bored by having to maintain your legacy systems? ADF provides a chance to work on a new technology which is compelling for staff.

· Training courses are available - Detailed training courses are available allowing managers to plan a skills transfer or upgrade to the JDeveloper & ADF platforms.

UTL_FILE will not do implicit character conversion

UTL_FILE will not do implicit character conversion Recently we migrated a database from one server to another. We used this occasion to change the character set of the database from WE8ISO8859P15 to AL32UTF8. After this migration we started to see invalid characters in our database tables. This was due to the fact that utl_file will not use the NLS_LANG settings of your OS. So if on your...

Number column as boolean

Number column as boolean When you use an Oracle database, you don't have a boolean type to use in your tables. Usually, you work around this problem by using a numeric column with values 0 and 1. This however could cause some extra programming work when building an application on top of your database. The numbers have to be converted to booleans, and vice versa. Now, in ADF...
