Integrating and Extending BIRT

Chapter 10. Using Java to Write an Event Handler

Creating a Java event handler is slightly more complex than creating a JavaScript event handler because you cannot simply enter Java code directly in the BIRT report designer. To create a Java event handler class, you must compile the source for the Java class and make certain that the class is visible to BIRT. Creating a Java event handler for BIRT is simplified, however, by the fact that Eclipse is a robust Java development environment and supports integrating a Java project with a BIRT project.

This chapter discusses the following topics:

• Writing the event handler class

• Making the event handler class visible to BIRT

• Associating the event handler class with a report item

• Understanding the classes ...
