Java Beans

Using Java Beans is a flexible way to insert your own elements into a report. A Java Bean element is a view of a lightweight Java bean class that extends Component (for example javax.swing.JButton). The public properties (member variables) of a Java Bean can be assigned to static or formula values in the Java Bean properties dialog. At design time the Java Bean properties are set and a 'screenshot' of the bean is inserted into the report.

Please note that the Java classes you would like to add as Java Beans must be in the classpath of i-net Designer.

Usage:

When you select Insert->Java Bean (or press the Java Bean toolbar button) you see the 'Add Java Bean' dialog which shows the Java Beans currently available to use in the report. To add a Java Bean to this list type in the beans class name in the class name field an press the add button. From the list select the Java Bean you would like to add to the report (see Example beans) then press the OK button and insert the Java Bean into the desired report location by dragging the mouse.

Once the Java Bean is placed in the report you can select 'Properties...' in the context menu and change the bean properties in the category: 'JavaBean'.
