OVERVIEW OF THE OA-FRAMEWORK COMPONENTS<\/a><\/h3>\n

OA-Framework is a very rich and powerfull development tool ; we will not start an in-depth discussion about how it works, but here is the main vocabulary you will need :<\/p>\n

<\/strong>
\nMDS\u00a0<\/span>–\u00a0The declarative metadata repository used with 11.5.10+ OA Framework applications. This replaced the older AK Repository.<\/p>\n

Page<\/span>
\nThe first component is the page ; a page is a set of regions (header, footer, table\u2026), and each region can contain items (field, button, checkbox…), or other regions.<\/strong>
\n
\n<\/strong>Pages are XML files found under $APPL_TOP\/MDS folder example:-<\/strong>
\n$appl_top\/pa\/11.5.0\/mds\/project\/webui\/MyProjectsPG.xml<\/strong><\/p>\n

BC4J : Business Components for Java<\/span><\/strong>
\nBC4J is a set of java libraries that meshes SQL database concepts like views, tables and transactions into the Java world via View Objects (VOs), Entity Objects (EOs), and Application Modules (AMs).<\/p>\n

All\u00a0BC4J components<\/strong>\u00a0are found under $JAVA_TOP example:-<\/p>\n

Application Module, View Object, View Link, PVO\u00a0<\/strong>found under:-
\n$JAVA_TOP\/oracle\/apps\/pa\/project\/server\/<\/p>\n

Controller<\/strong>\u00a0found under:- $JAVA_TOP\/oracle\/apps\/pa\/project\/webui\/<\/p>\n

Entity Object, Validation View Object, Validation Application Module<\/strong>found under:-
\n$JAVA_TOP\/oracle\/apps\/pa\/project\/scheme\/server\/<\/p>\n

View Object<\/span><\/strong>
\nIn the simplest terms, a BC4J view object encapsulates a database query and provides iteration over and access to the view rows in its result set.<\/p>\n

Entity Object<\/span><\/strong>
\nWhen we handle data through a page – INSERT \/ UPDATE \/ DELETE – we do this by using an Entity Object. An Entity Object is a java representation of a table ; each column of the table is mapped to an „Entity Attribute”.<\/p>\n

Application Module<\/span><\/strong>
\nAn application module is a container for related BC4J objects. The AM is connected to the database, and is responsible for the commit and rollback of a transaction.<\/p>\n

Controller<\/span><\/strong>
\nThe controller is the java code in charge of loading a page when we call it. It is also in charge of handling an event on a page, like a click on a button, or the call of a List Of Values. It has three\u00a0Methods:-

\n1. ProcessRequest<\/strong>
\n2. ProjcessFormData<\/strong>
\n3. ProcessFormRequest<\/strong><\/div>\n","protected":false},"excerpt":{"rendered":"
