To set breakpoints on Java event handler code, use the standard Eclipse Java Development Tools (JDT) user interface. The JDT UI (org.eclipse.jdt.ui) plug‑in implements the Java-specific user interface classes that manipulate Java elements. Packages in the JDT UI implement the Java-specific extensions to the workbench. During report execution, the report engine stops at each specific breakpoint. Developers can then inspect report item instances and variable values in the current context.
