title	Should I Create My Own JBI Components?

NOTE: Before beginning this tutorial, please take the time to read the FAQ entry titled Should I Create My Own JBI Components?. It is very important that you understand the reason for developing a JBI binding component and this FAQ entry will explain this.

This tutorial describes how to create a very simple Hello World style of JBI binding component. This tutorial is as minimalistic as possible so as to focus on key concepts and not drown in details. The Hello World binding component will respond to all requests with the message:

<hello>Hello World! Message \ [<original message here>\] contains \ [??\] bytes.</hello>

Wiki Markup

The following sections will walk through the creation, packaging, testing and deployment of the Hello World binding component.

Prerequisites

Maven 2.0.4 7 or higher
- If you have never used Maven previously the Maven Getting Started Guide explains some valuable concepts surrounding Maven
ServiceMix 3.2.1 -incubating or higher
See the ServiceMix downloads to grab a nightly build as ServiceMix 3.1 has not yet been released
A broadband internet connection so Maven can automatically download dependencies

...

$ mvn archetype:create \ -DarchetypeGroupId=org.apache.servicemix.tooling \ -DarchetypeArtifactId=servicemix-binding-component \ -DarchetypeVersion=3.2.1 -incubating \ -DgroupId=org.apache.servicemix.samples.helloworld.bc \ -DartifactId=hello-world-bc \ -DremoteRepositories=http://people.apache.org/repo/m2-incubating-repository^{Image Removed}

The command above will create a directory named hello-world-bc that houses a Maven project for the JBI service engine being created here. The name of the directory is taken from the artifactId parameter.

The first three parameters to the mvn command (-DarchetypeGroupId=org.apache.servicemix.tooling -DarchetypeArtifactId=servicemix-binding-component -DarchetypeVersion=3.2-incubating-SNAPSHOT.1) identify which Maven archetype to use for the archetype:create goal, while the last two parameters (-DgroupId=org.apache.servicemix.samples.helloworld.bc -DartifactId=hello-world-bc) uniquely identify the Maven project that is being generated. The groupId is used as the Java package and the artifactId is used as the project name. Therefore, only alphanumeric characters are valid values for the groupId and artifactId parameters. The very last parameter tells Maven to look at the Incubator repository at the ASF. Because Incubator policy disallows incubating projects to publish artifacts outside of the Incubator repository, the remoteRepositories system property tells Maven to use the Incbator repositorythe project name. Therefore, only alphanumeric characters are valid values for the groupId and artifactId parameters.

Tip
The value of the `archetypeVersion` parameter in the command above (3.2.1-incubating) may need to be updated to the current ServiceMix version in order for the command to work correctly. The latest version can always be found in the top level ServiceMix POM in the `<version>` element.

src/main/java/org/apache/servicemix/samples/bc/MyBootstrap.java - Implements javax.jbi.component.Boostrap which is called by the JBI container as part of the component lifecycle (i.e.g, when the component is installed and uninstalled). This is where you place logic to set up and tear down things when the component is started and stopped. This class is no longer needed.

src/main/java/org/apache/servicemix/samples/bc/MyComponent.java - Extends the DefaultComponent, a convenience class that makes creating JBI components much easier and provides some additional lifecycle management for the BC when it's deployed to the JBI container. This class should be fleshed out by overriding methods in the DefaultComponent to configure and initialize the component.

Notice that not only do we see that the build was successful, but also note the text in the output above that was printed by the test: unmigrated-wiki-markup

*<?xml version="1.0" encoding="UTF-8"?><hello>Message \ [Ski Colorado!\] contains \ [13\] bytes</hello>*

This is the message we were expecting to be output from the test. So if you see this, you just wrote a JBI component and tested your first JBI BC successfully.

Note

title	TODO

The default implementation of the component accepts InOut MEPs (ADD
LINK TO FURTHER READING CONCERNING MEPs) and return the input content
as the out message. This is already nearly what we want.

OUTLINE for further work:

Get Messages
read Messagesunmigrated-wiki-markup
count the bytes
Maybe easiest by XSLT endpoint (can be used to apply an XSLT stylesheet to the incoming exchange and will return the transformed result as the output message.)
see \ [ servicemix-saxon\|servicemix-saxon\]
send a message back
Configure SA so that the example receives messages
create & populate
C:\hello-world-SE-SU-SA\hello-world-SU\src\main\resources\servicemix.xml
as MyDeployer extends AbstractXBeanDeployer create xbean.xml for SU
make something send messages (eg quartz timer, HTTP POST,...) and dump the answer (eg TraceComponent, FireWriter, EIP,...)
add a chapter what user may do now / "how to continue when having the working example"

Classpath for SU to include manually till v3.1, see mail

manually editing http://goopen.org/confluence/display/SM/Working+with+Service+Units
manually editing http://www.servicemix.org/site/working-with-service-assemblies.html
use the SU archetype like in http://www.servicemix.org/site/creating-a-protocol-bridge.html
use the SA archetype like in http://www.servicemix.org/site/creating-a-protocol-bridge.html

INS When to use this JBI Component
INS Using the component that you created

provide exact position in the SVN!
/samples/hello-world-SE-SU-SA/
integrate from SVN source like it is done at Configuration at http://www.servicemix.org/site/visualisation.html

maybe moving the content of overlapping existing docus to this new tut and - where appropriate - delete the old ones (only leaving a redirect).
http://www.servicemix.org/site/notes-on-creating-jbi-component-using-maven2.html version14
http://www.servicemix.org/site/creating-a-standard-jbi-component.html version26
are already fully incorporated in the mentioned versions, so delete content and point from there to here (and delete note at the very top)

This shall already include everything stated at
http://www.servicemix.org/site/maven-jbi-plugin.html#MavenJBIplugin-GettingStarted
and
http://www.servicemix.org/site/working-with-components.html

provide additional reading
Creating a protocol bridge.for a "bigger" example
The examples page lists examples providing more information, showing further possibilities and components.
