The Eclipse platform is an Open Source, integrated system of application development tools that you implement and extend using a plug-in interface. Eclipse provides a set of core plug-ins that configures the basic services for the platform's framework. A platform developer can build and integrate new tools in this application development system. Business Intelligence Reporting Tool (BIRT) is a set of plug-in extensions that lets a developer add reporting functionality to an application. The APIs in BIRT define extension points that let the developer add custom functionality to the BIRT framework. This article describes how to create a BIRT extension using the Eclipse Plug-in Development Environment (PDE). The example adds a custom report item, RotatedLabel, to the BIRT Report Designer Palette that a report developer can drag-and-drop into a report design, as shown i... (more)

How to Develop an Application Using the Eclipse BIRT Design Engine API

This article is the second in a series on developing an application using Eclipse BIRT Engine APIs. It focuses on developing an application using the Eclipse BIRT Design Engine API. The last article focused on the Eclipse BIRT Report Engine API. The Eclipse Business Intelligence Reporting Tool (BIRT) is a set of plug-in extensions that enable a developer to add reporting functionality to an application. BIRT provides a Design Engine API that a developer can use to create a customized report design application. The org.eclipse.birt.report.engine.api package contains a set of inte... (more)

Using JSAPI with a JBoss SEAM Component

If you are using Actuate's JSAPI to run BIRT reports and you wish to pass parameters from a SEAM component this can be done very easily. In addition you can combine SEAM remoting with the JSAPI to do some interesting things. For example assume we create a SEAM component that retrieves report parameters that we want to use with the JSAPI. The component would look similar to this: package com.actuate.seam.example; import org.jboss.seam.annotations.*; import org.jboss.seam.*; import org.jboss.seam.annotations.remoting.WebRemote; @Name("reportParameters") @Scope(ScopeType.SESSION) publi...

Raising Errors in Event Handlers

Let me start with a simple scenario.  You are writing a BIRT event handler and you expect the user to set a UserDefinedProperty that will guide the event handler code.  How do you handle the situation where the user forgets to add the UserDefinedVariable?  How do you provide a message back to the user to help them solve the problem? In the past I have focused on using logging and stepping through code.  While effective, it requires the person using your event handler code to have a relatively high level of sophistication.  Wouldn't it be great if you could pass an error message f...
