Birt Pojo Data Source Examples
Use esProc with BIRT. Here is the SPL script. Your BIRT reports can have a query from two data sources no matter what kind of database and go on other computations that are not convenient on BIRT.
Using POJO DataSource in BIRT 4.3 To create a report in BIRT 4.3 we can use POJO dataSource. In 4.3 this DataSource is supported. To use this we need to create a dataset class.
BIRT is an open source engine to create data visualizations that can be integrated into Java web applications. It's a top-level software project within the Eclipse Foundation and leverages contributions by IBM and Innovent Solutions. It was started and sponsored by Actuate at the end of 2004.
Eclipse Birt Pojo Data Source
Primary tabs
. Data - Databases, web services, Java objects all can supply data to your BIRT report. BIRT provides JDBC, XML, Web Services, and Flat File support, as well as support for using code to get at other sources of data. BIRTs use of the Open Data Access (ODA) framework allows anyone to build new UI and runtime support for any kind of tabular data.

Test Suite (1)
100968 Provide Daily Build Test Reports on eclipse.org.birt Web Site (closed/fixed)
In a previous blog post I created a skeleton class for rendering a report using BIRT runtime. You can pass it the report parameters, the report definition (rptdesign) and an OutputStream and it will render HTML to that stream.
If your report definition contains graphs we run into a problem. Normally, in HTML an image is a separate resource. BIRT will generate the images containing your graphs in a temporary directory and will link to them in your HTML. For this to work, you will have to configure the Platform to write the images to a publicly accessible directory and write the links using the correct domains. Furthermore, you’ll probably need some process to clean up the images after the reports have been viewed. If your reports are being used in some website and generated on the fly, this is most likely quite difficult to determine. Maybe when the user logs out?
Luckily, in modern browsers we can embed the images in the same stream, bypassing the need of a temporary directory. The following trick will encode the image with base64 and embed it directly into the HTML stream using css data . This will work on most modern browsers but of course Internet Explorer lags a bit behind. PNG support is available up until 32kb in Internet Explorer 8 and SVG not at all. Internet Explorer 9 works fine, as well as the other major browsers.
So how does it work? First, we explicitly tell the render engine to use PNG or SVG. SVG provides sharper images but will not work in Internet Explorer 8 as mentioned above. Next, we inject our own HTMLServerImageHandler which encodes the image data to base64.
