We also need a Java object model that mirrors the XML schema. This will be composed 
of the 
BarbecueComponent
interface which extends the 
net.sf.jasperreports.engine.component.Component
interface and contains 
fields that match the 
barbecue
XML element properties. We will use the default 
implementation of the Barbecue component interface called 
StandardBarbecueComponent
:
public class StandardBarbecueComponent implements 
BarbecueComponent, Serializable 
{
private String type;
private boolean drawText = true;
private JRExpression codeExpression;
...
}
Now we need to take care of the transformations of XML fragments to Java objects and 
back.
Parsing an XML fragment into a corresponding Java object is done by writing a class 
that defines Commons Digester rules that apply to the 
barbecue
XML elements. 
JasperReports uses the 
net.sf.jasperreports.components.ComponentsXmlHandler
class for this 
operation. The class registers rules as the following:
String barcodePattern = "*/componentElement/barbecue";
digester.addObjectCreate(barcodePattern, 
StandardBarbecueComponent.class);
Producing XML fragments from a 
BarbecueComponent
object is the task of the 
writeToXml
method of the same class. The method receives a component instance and 
an XML report writer and outputs to the writer the XML fragment that corresponds to 
the component.
We will now write the code that manages barcode components during report 
compilation. At report compilation time, custom components need to be validated, 
expressions need to be collected from them and component instances have to be 
generated for inclusion in compiled reports. The 
BarbecueCompiler
class contains 
three methods that take care of these tasks. The verify method checks that the barcode 
expression and type have been specified (and logs broken rule errors if the component is 
not valid), the 
collectExpressions
method collects the expression embedded into the

component, and the 
toCompiledComponent
method creates a barcode object which 
includes the compiled expression instance obtained from 
net.sf.jasperreports.engine.base.JRBaseObjectFactory
(which is an object 
factory that produces object instances for compiled reports).
As report compilation has been covered, we go on to the next phase in a report's life 
cycle, namely report fill. At fill time, we need to get a barcode component instance as 
designed in a report template, collect dynamic data from the report data set and produce 
an element that will get included in the generated report. This is the job of a class that 
implements the 
net.sf.jasperreports.engine.component.FillComponent 
interface, and we will name our implementation 
BarbecueFillComponent
. Fill 
component instances are created by a factory class called 
BarbecueFillFactory
.
The 
BarbecueFillComponent
class extends the abstract 
net.sf.jasperreports.engine.component.BaseFillComponent
class that 
provides basic functionality for component fill implementations. The class includes 
methods that are called by the engine at different stages during the fill process.
The evaluate method evaluates the barcode expression and stores the result in a class 
member which is going be used later in the process:
public void evaluate(byte evaluation) throws JRException 
{
code = (String) fillContext.evaluate(
barcodeComponent.getCodeExpression(), evaluation);
}
The prepare method allows the fill component to decide whether it will produce an 
output element, and whether it needs to stretch the space assigned at design time for the 
element in order to fit the generated output. The fill barcode implementation checks 
whether the barcode expression has yielded a non null result and specifies in this case 
that it will produce a print element that does not stretch; otherwise it specifies that it will 
not produce an output element:
public FillPrepareResult prepare(int availableHeight)
{
return code == null ? FillPrepareResult.NO_PRINT_NO_OVERFLOW
: FillPrepareResult.PRINT_NO_STRETCH;
}
Before implementing the fill method which will actually produce the report element that 
will get included in the filled report, we get to the point where we need to come up with 
what we want to include in the generated report. Barcodes can be rendered as images, so 
writing an image renderer that knows how to draw a barcode would do the job. Thus we 
write the 
BarbecueRenderer
class which is a SVG renderer that uses the Barbecue API 
to draw a barcode.
Now that we have the barcode image renderer, we can write the fill method of 
BarbecueFillComponent
which will create images that use this renderer. The method

uses the evaluated barcode expression and the barcode component attributes to create a 
barcode renderer:
BarcodeInfo barcodeInfo = new BarcodeInfo(); 
barcodeInfo.setType(barcodeComponent.getType()); 
barcodeInfo.setCode(code); 
barcodeInfo.setDrawText(barcodeComponent.isDrawText()); 
... 
Barcode barcode = providers.createBarcode(barcodeInfo); 
BarbecueRenderer renderer = new BarbecueRenderer(barcode);
Then an image element object is created. The image element uses a template image 
object to store common attributes and the barcode renderer is set as image renderer:
JRTemplatePrintImage image = new 
JRTemplatePrintImage(templateImage);
image.setX(element.getX());
...
image.setRenderer(renderer);
We have all the code required to handle barcode components and we need to put it all 
together into a component package. Components are registered as JasperReports 
extensions, and we will use a hard coded extension factory for our component. We will 
write a class that implements 
net.sf.jasperreports.extensions.ExtensionsRegistryFactory
and returns 
our component implementation as extension. In the JasperReports source, this class is 
net.sf.jasperreports.components.ComponentsExtensionsRegistryFactory
The class creates a component manager object which glues handler classes used for 
report compilation and filling. Component transformations between JRXML and object 
model are the responsibility of an XML handler object, which also specifies the XML 
namespace and schema for the component.
To register the component extension, we will need to write a 
jasperreports_extension.properties
file and put it as a resource at the root of our 
class folder. The file contains a property that registers our extension factory:
net.sf.jasperreports.extension.registry.factory.components=net.sf.j
asperreports.components.ComponentsExtensionsRegistryFactory
To wrap everything up, the classes need to be compiled and packaged into a JAR file 
together with the rest of the resources used by the code. Alternatively, we can place on 
the classpath a directory that contains the compiled classes and resources.
To pick the fruits of our labor, we will write a sample report that contains a barcode 
component. The component report element will look like this:
<componentElement>
<reportElement x="0" y="100" width="400" height="50"/>
