Developing an Eclipse BIRT Report Item Extension

Architecture and framework

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 in Figure 1.

The sample code for the plug-in creates a label in the runtime report that renders text at a specified angle. Figure 2 shows the display text rotated at an angle of 45 degrees.

A developer uses the Eclipse PDE to create, develop, test, debug, and deploy a plug-in. The Eclipse PDE supports host and runtime instances of the workbench project. The host instance provides the development environment. The runtime instance lets you launch a plug-in to test it.

To implement the report item extension, the plug-in developer does the following tasks:

  • Configures the plug-in project in the Eclipse PDE
  • Adds the report item to the Report Designer Palette using the report item UI extension point.
  • Adds the report item definition to the Report Object Model (ROM) using the report item model extension point.
  • Adds rendering behavior to the report item using the report item presentation extension point.
  • Deploys the report item extension to the Eclipse plug-in environment
An Eclipse plug-in implements the following components:
  • Plug-in manifest - An XML document that describes the plug-in's activation framework to the Eclipse runtime environment
  • Plug-in runtime class - A Java class that defines the methods for starting, managing, and stopping a plug-in instance
  • Extension-point schema definition - An XML document that specifies a grammar that you must follow when defining the elements of a plug-in extension in the Eclipse PDE
In the Eclipse PDE Workbench, the developer can create the framework for a plug-in extension by using the Manifest Editor to generate the plug-in manifest and class templates based on the definitions in the extension-point schemas.

In the Eclipse PDE, create a new project for the rotated label report item extension by choosing File->New->Project and selecting the Plug-in Project wizard. In Plug-in Project, modify the settings, as shown in Table 1.

In Plug-in Content, modify the settings, as shown in Table 2.

Figure 3 shows the host instance of the Eclipse PDE with the rotated label report item extension project open in the Manifest Editor.

After defining the plug-in project, specify the list of plug-ins that must be available on the classpath of the rotated label report item extension to compile and run. On PDE Manifest Editor, choose Dependencies. In Required Plug-ins, remove the following plug-ins:

  • org.eclipse.ui
  • org.eclipse.core.runtime

    Choose Add. Plug-in Selection appears. In Plug-in Selection, select the following plug-ins:

  • org.eclipse.emf.ecore
  • org.eclipse.birt.report.designer.ui
  • org.eclipse.birt.report.model
  • org.eclipse.draw2d
  • org.eclipse.birt.report.engine
  • org.eclipse.jface.text
  • org.eclipse.core.runtime
  • org.eclipse.birt.core
  • org.eclipse.ui
  • org.eclipse.birt.core.ui
The order of the list determines the sequence in which a plug-in loads at runtime. Use Up and Down to change the loading order as necessary. The rotated label report item extension doesn't need any changes to the loading order if you select the required plug-ins in the order listed in the previous step.

On PDE Manifest Editor, choose Extensions. On Extensions, declare the extension points required to implement the rotated label report item plug-in and add the extension element details. The Eclipse PDE uses the XML schema defined for each extension point to provide the list of valid attributes and values specified for the extension elements.

To add an extension point, choose Add. New Extension appears. In Available extension points, select the plug-in that contains the extension point.

Now that the world has connected “things,” we need to build these devices as truly intelligent in order to create instantaneous and precise results. This means you have to do as much of the processing at the point of entry as you can: at the edge. The killer use cases for IoT are becoming manifest through AI engines on edge devices. An autonomous car has this dual edge/cloud analytics model, producing precise, real-time results. In his session at @ThingsExpo, John Crupi, Vice President and Eng...
There are 66 million network cameras capturing terabytes of data. How did factories in Japan improve physical security at the facilities and improve employee productivity? Edge Computing reduces possible kilobytes of data collected per second to only a few kilobytes of data transmitted to the public cloud every day. Data is aggregated and analyzed close to sensors so only intelligent results need to be transmitted to the cloud. Non-essential data is recycled to optimize storage.

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm.
