Component Family	Context
Function	cConfig manipulates the CamelContext, which is the single routing rule base in a Route.
Purpose	cConfig allows you to set the CamelContext using Java code.
Basic settings	Imports	Enter the Java code that helps to import, if necessary, external libraries used in the Code box.
	Code	Write a piece of code to manipulate the CamelContext.
	Dependencies	Select the library or libraries that is required by the CamelContext or Typeconverter Registry from the list.
Usage	cConfig cannot be added directly in a Route.
Limitation	n/a

Scenario: Implementing a dataset from the Registry

In this scenario, an instance of dataset is added in the Registry and implemented by a
cMessagingEndpoint component.

Dropping and linking the components

From the Palette, expand the Context folder, and drop a cConfig component onto the design workspace.
Expand the Messaging folder, and drop a cMessagingEndpoint component onto the design
workspace.
Expand the Processor folder, and drop a cProcessor component onto the design
workspace.
Right-click the input cMessagingEndpoint component,
select Row > Route from the contextual menu and click the cProcessor component.
Label the components to better identify their functionality.

Configuring the components

Double-click the cConfig component, which is labelled
Create_dataset, to display its
Basic settings view in the Component tab. and set its parameters.

Write a piece of code in the Code field
to register the dataset instance foo into
the registry, as shown below.

org.apache.camel.impl.SimpleRegistry registry = new
org.apache.camel.impl.SimpleRegistry();
                registry.put("foo", new 
org.apache.camel.component.dataset.SimpleDataSet());
camelContext.setRegistry(registry);

org.apache.camel.impl.SimpleRegistry registry = new

org.apache.camel.impl.SimpleRegistry();

registry.put("foo", new

org.apache.camel.component.dataset.SimpleDataSet());

camelContext.setRegistry(registry);

Double-click the input cMessagingEndpoint
component, which is labelled Read_dataset, to display its Basic
settings view in the Component tab.
In the URI field, enter
dataset:foo between the quotation marks.
Double-click the cProcessor component,
which is labelled Monitor, to display its
Basic settings view in the Component tab.
In the Code box, customize the code as
follows so that the Run console displays
the message contents:

System.out.println("Message content: "+ exchange.getIn().toString());

1
2

System.out.println("Message content: "+
exchange.getIn().toString());
Press Ctrl+S to save your route.

Viewing code and executing the Route

Click the Code tab at the bottom of the
design workspace to have a look at the generated code.

As shown in the code, a message route is built from the endpoint identified
byRead_dataset and cProcessor_1 gets the
message content and displays it on the console.
Click the Run view to display it and
click the Run button to launch the
execution of your route. You can also press F6 to execute it.

RESULT: The message content is printed in the console.
