From the Product Description: This book also includes extensive examples of how to use the Eclipse Plug-in Development Environment to build plug-ins to extend the features of the BIRT framework. The source code for these examples is available for download. This book has been updated with the latest material from BIRT 3. This revised and expanded third edition also features the following new content: Readers may be interested in this book? A Field Guide, Third Edition , the authoritative guide to using BIRT Report Designer, the graphical tool that enables users of all levels to build reports, from simple to complex, without programming.

The BIRT report engine is thread-safe, so this single-instance recommendation is not a restriction. At termination, the application should call shutdown to unload extensions and delete temporary files. The EngineConfig class contains the configuration settings for the report engine. Use the EngineConfig object to specify the settings for the following properties: HTML emitter configuration for custom handling of images or actions for HTML output Logging to set the logging file location and level Platform context to indicate whether the application and engine home are in a stand-alone environment or packaged as a WAR file Resource files to set the location where the reporting application can access libraries and properties files Scripting configuration to provide external values and Java resources to scripting methods The engine home is the key property that the report engine requires.

The report engine cannot parse the report design or run the report without a defined engine home. For a stand-alone application, the engine home is an absolute path to a file system location. For an application running from a WAR file on an application server, the engine home is a relative path in the WAR file. Two engine configuration properties depend on whether the environment in which the application runs is stand-alone or in a WAR file on an application server.

These properties are the platform context and the HTML emitter configuration. The platform context provides the report engine with the mechanism to access files. The HTML emitter configuration provides the functionality for processing images and handling hyperlinking and bookmark actions.

A ReportEngine constructor takes the EngineConfig object as its argument. If the configuration object is null, the report engine uses the default configuration.

Listing 1 shows how to set up a report engine in a stand-alone application. The application uses the engine home located in the BIRT runtime directory. The report output format is HTML.

The application configures the HTML emitter and creates the report engine using the settings contained in the EngineConfig object. To open a report design, call one of the openReportDesign methods on ReportEngine. These methods instantiate an IReportRunnable object using a String object that specifies the path to a report design or an input stream. To open a report document, call the ReportEngine. This method instantiates an IReportDocument object using a String object that specifies the path to a report document.

This method returns the IReportDocument object. You must handle the EngineException that these methods throw. The IReportRunnable object provides direct access to basic properties of the report design.

The names of report design properties are static String fields, such as IReportRunnable. To access a report design property, use the getProperty method with a string argument that contains one of these fields.

To access and set the values of parameters, use methods on a parameter definition task object, described later in this article. Listing 2 shows how to open a report design and find a property value. If the engine cannot open the specified report design, the code shuts down the engine. The variable, engine, is a ReportEngine object. The IReportDocument object provides access to the data in a report and the report's structure. IReportDocument provides methods to retrieve table of content entries, bookmarks, and page information.

To access table of content entries, use the findTOC method. To find the root table of contents entry, use a null argument. To find the subentries of a table of contents entry, use the getChildren method. This method returns a list of TOCNode objects.

In turn, you can use the Bookmark object as an argument to the getPageNumber method, which returns the number of the page to which the bookmark links. With this information, you can specify particular pages to render to a formatted report. Listing 3 shows how to open a report document and navigate its table of contents to find a page.

Accessing a Report Parameter Programmatically A report parameter is a report element that provides input to a report design before the application generates the report. Report parameters have attributes that a reporting application can access. The most commonly used attributes are name and value.

The report engine uses the report design logic and the report parameter values to perform tasks such as filtering a data set or displaying an external value in the report.

After the reporting application sets the values for the report parameters, it passes these values to the task that generates the report.

Listing 4 shows how to set the value of a report parameter that has a known name. The sample creates a HashMap object that contains the parameter values to use later to run the report. The variable, runnable, is an object of type IReportRunnable. The application configures the HTML emitter and creates the report engine using the settings contained in the EngineConfig object. To open a report design, call one of the openReportDesign methods on ReportEngine.

These methods instantiate an IReportRunnable object using a String object that specifies the path to a report design or an input stream. To open a report document, call the ReportEngine. This method instantiates an IReportDocument object using a String object that specifies the path to a report document. This method returns the IReportDocument object. You must handle the EngineException that these methods throw.

Book review: Integrating and Extending BIRT by Jason Weathersby, Don French, et al

This sample does not show the details of the code for retrieving the parameter value from a user interface or a database. The code to perform these tasks depends on your application's requirements. You can also provide custom output formats by creating a new renderer from the rendering extension points. Three task classes support generating a report from a source.

The tasks that you use to generate a report from the source are: IRunAndRenderTask: An object of this type creates a report in unpaginated HTML format by running a report design directly. IRunTask: An object of this type creates a report document. To instantiate this object, call the ReportEngine method, createRunTask. After creating the report document, create the report with an IRenderTask object. IRenderTask: An object of this type creates a complete report or a set of pages from a report by formatting the contents of a report document.

To instantiate this object, call the ReportEngine method, createRenderTask. Each type of task object can act on multiple sources. When the application no longer needs the task object, call the task's close method.

The options must specify either an output file name or a stream. Other configuration options, such as setting whether to create embeddable HTML, are optional.

There are no format-specific options for PDF output. Listing 5 shows how to use rendering options on an IRunAndRenderTask object to set report parameter values, the output format of the report, and the output file name.
