h1. Developing OSGi components with EIK

This chapter describes how to develop a osgi component with EIK.
Now we have a functional karaf environment in Eclipse, and we will illustrate howto develop a debug simple Camel route

For this example we use apache servicemix 4.4.2.

Using command line, we can create our project:
{noformat}
mvn archetype:generate \
  -DarchetypeGroupId=org.apache.karaf.eik.archetypes \
  -DarchetypeArtifactId=eik-camel-archetype \
  -DarchetypeVersion=0.9.0-SNAPSHOT \
  -DgroupId=org.apache \
  -DartifactId=eik-camel-osgi-project \
  -Dversion=1.0.0-SNAPSHOT 
{noformat}
as soon as possible this archetype will be available for m2e 


*Additional parameters*

During the maven creation process, additional questions will be asked on the console :

* Define value for property 'camel-version':
  The version of camel we want to use

* Define value for property 'slf4j-version':
  The version of slf4j we want to use

*Result of Maven command execution*

Using Eclipse IDE we can import package for our needs in the project, the package available are those present in target platform.
To do that we need do double click on the MANIFEST.MF >  Dependencies you can use UI to import package

EIK feature allows Automatic deployment of workspace plugin projects.
If you check Run configurations or in Debug configurations. You will see your project
