Complex data controls
In our previous chapters, we have seen the usage of basic data controls that are used to
provide an interface between the model layer and the UI layer. There are other data controls
that ADF supports for integraion and interoperability. All these data controls are created by
going to New Gallery | Data Control . The following are some of these data controls:
URL data control : We can create a data control that is based on a URL. Basically, we
can have an Excel spreadsheet uploaded in a URL, and based on the informaion in
this spreadsheet it is possible to create a data control in ADF. Files other than Excel
spreadsheets that are supported are XML and REST services.
Web service data control : In ADF, it is possible to create a data control based on
the WSDL informaion of a web service running on a server. The service deiniion
is provided to define a data source for the data control.
Java and EJB data control : JavaBeans can be converted to a data control by simply
right-clicking on the bean and selecing the Create Data Control opion. An EJB
session bean can also be used to create a data control.
JMX data control : ADF also allows us to create a data control based on JMX Mbeans
found on the server.
Complex task flows
Some of the complex and advanced features of the task flow are discussed in the
following secions:
Trains : One of the reasons for using a task flow is that an ADF task flow allows the
user to add trains to a web applicaion, as shown in the following screenshot:
