How to Insert Barcode Images into BIRT using Barcode for Java?
Java Barcode Generator
Quick Navigate
FIRST Commercial Java Barcode Library Supports Eclipse BIRT
- barcode.jar (download from BarcodeLib.com)
- BIRT 2.2.2 or later version
If developer can find any problem with previous version of BIRT, please send email to support@barcodelib.com.
Here is the sample source code.
// get engine from Birt Bootstrapping...
// ...
reportDesign = engine.openReportDesign("C://foo.rptdesign");
//create task to run and render report
IRunAndRenderTask task = engine.createRunAndRenderTask(reportDesign);
//set options
PDFRenderOption options = new PDFRenderOption();
options.setOutputFileName("foo.pdf");
options.setOutputFormat("pdf");
task.setRenderOption(options);
// barcode is a com.barcodelib.barcode.Linear object
byte[] bytes = barcode.renderBarcodeToBytes();
task.getAppContext().put("imageBarcode", bytes);
//run and render report
task.run();
task.close();
So this was a simple Main Class using a Birt Engine to dynamicly put a byte[] to a report Context and run the report. Now do the following in the Report Designer:
Thats all. If everything works fine, the dialogs should look like below. When you now run your report the barcode should be visible where you placed the image container.

So this was a simple Main Class using a Birt Engine to dynamicly put a byte[] to a report Context and run the report. Now do the following in the Report Designer:
- Put an image on the report
- Define "Dynamic Image" as Type
- click "Select Image Data" Button
- In the DataBinding Dialog click the "Add..." Button
- define "foo" as "Column Binding Name"
- define "Any" as "Data Type"
- click Expression button
- use the following expression:
- reportContext.getAppContext().get("imageBarcode");
- check the checkbox in front of the "foo" entry in dialog
Thats all. If everything works fine, the dialogs should look like below. When you now run your report the barcode should be visible where you placed the image container.
