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 interfaces and implementation classes that supports integrating the design-time part of BIRT into a reporting application. Programming with a Report Design A reporting application typically generates a report from a report design. In this type of reporting application, you develop a report design... (more)

Accessing Spring Beans from the BIRT Designer

Java Developer Magazine on Ulitzer Recently I have described methods that can be used to access Spring Beans from the BIRT Engine. These examples are intended to be illustrative and not comprehensive. More on BIRT and Spring Calling Spring Objects from BIRT Expressions and Event Handlers In both of these examples I used the BIRT engine to retrieve Spring objects within the scripting environment. In this post I am supplying an example that illustrates how to implement your own menu in the expression builder, so Spring objects can be called within the BIRT Designer. This will allow... (more)

Calling Client Side JavaScript from a BIRT Chart

JavaScript Track at Cloud Expo A couple of months ago I detailed a new feature for BIRT charts that allows multiple hyperlinks to be attached to one the supported events. That post is available here. In this post I will discuss using a BIRT Text element that contains script which executes within the client browser and contains functions that are called from rendered charts. General Information BIRT currently supports interactivity on many chart components like chart series, title, axis, and the legend. The components that support interactivity will depend on the type of chart bein... (more)

BIRT Excel Output

BIRT 2.5.2 provides a variety of tools to construct reports to analyze data. These include charts, aggregation elements, drill to detail capabilities, nested tables, data cubes and crosstabs. These features are presented very well in the AJAX based viewer when deployed to the web, supporting pagination, table of contents, and exporting of data and contents to other formats. Out of the box, BIRT supports exporting to HTML, paginated HTML, WORD, PDF, PostScript, PPT, and Excel. BIRT also provides an extension point to implement your own emitters. For an example of implementing an X... (more)

What's the Difference Between dataSetRow["FIELD"] and row["FIELD"]

One of the most common questions for people that are new to BIRT is about how to ask data from the DataSet in the report.  The question is when building expressions should I use dataSetRow["FIELD"] or row["FIELD"]? So let me see if I can set the record straight.  When data is acquired, it is acquired by a DataSet, so the following query in a JDBC DataSet will create a three field resultset: select CITY, STATE, COUNTRY from CUSTOMERS Any script or expressions written on the DataSet will be written to use the format row["FIELD_NAME"]; So if we add a computed column to the DataSet c...
