Accessing Enterprise Data

Nexaweb Studio provides functionality to aid you in connecting your Nexaweb client applications to an XML or Java data source.

Nexaweb Studio data support allows you to bind data to:

A table or a list box in an existing UI component
Any UI widget, component, or widget/component attribute
A form in a new UI file

See Concepts – Data Framework in the Nexaweb Platform 4.2 documentation, for more information on the Nexaweb Platform resources for adding data to your applications.

You can access the wizards to create the components for enabling applications to access enterprise data as follows:

Option

Description

Data View

Available in the Nexaweb Data perspective when you:

Right click on a node in the Data view, or
Drag a file from the Data view into a UI file

Launches wizards with some fields already completed.

The Data view displays all of the data elements created for each of the UI files in your project similar to Figure 116. It allows you to associate data elements with each other by dragging and dropping elements between the data source, bindings, iterators, and formatters nodes displayed in the Data view.

Data Support Menu

Available in the Nexaweb Visual Editor perspective when you:

Right click in a UI file, or
Drag a file from the Package Explorer or Navigator views into a UI file

Launches mostly blank wizards.

Although the Nexaweb Visual Editor perspective displays data elements in the Outline view, you cannot work with data elements in the Outline view by dragging and dropping them onto each other.

You can use data elements created for one UI file in another UI file; however, if you do so, you must make the data element available at runtime.
