Getting started

iPOJO

Tutorial

Follow the tutorial http://felix.apache.org/documentation/subprojects/apache-felix-ipojo/apache-felix-ipojo-gettingstarted/ipojo-hello-word-maven-based-tutorial.html

Source code : http://repo1.maven.org/maven2/org/apache/felix/org.apache.felix.ipojo.distribution.maventutorial/1.12.1/org.apache.felix.ipojo.distribution.maventutorial-1.12.1.zip

Training

0) Create a directory for the project

(install Felix, Maven 3, Java 8 before)

mkdir ipojo_training
cd ipojo_training

1) Create 1 bundle containing a server component

Generating the bundle skeleton with the iPOJO archetrype http://felix.apache.org/documentation/subprojects/apache-felix-ipojo/apache-felix-ipojo-tools/ipojo-maven-plug-in.html


mvn archetype:generate -DarchetypeGroupId=org.apache.felix -DarchetypeArtifactId=maven-ipojo-plugin -DarchetypeVersion=1.12.1

Define value for property 'groupId': : hello
Define value for property 'artifactId': : hello_server
Define value for property 'version':  1.0-SNAPSHOT: : 0.1.0-SNAPSHOT
Define value for property 'package':  hello: : hello.server

cd hello_server
mvn clean install
more bundle.properties 
more src/main/java/hello/server/HelloComponent.java

2) Deploy the bundle on the running Felix framework

Start Felix

cd felix-framework-5.6.1/
java -jar bin/felix.jar

First commands

help
lb

Install the bundle jarfile (Note: install file://C:... on Windows)

help install
install /Users/YOUR_USERNAME/.m2/repository/hello/hello_server/0.1.0/hello_server-0.1.0.jar
lb
start BUNDLE_ID

What's happen ?

headers BUNDLE_ID

Deploy the required package dependencies (ie Import-Package)

obr:deploy "OSGi R4 Compendium Bundle"
start http://central.maven.org/maven2/org/apache/felix/org.apache.felix.ipojo/1.12.1/org.apache.felix.ipojo-1.12.1.jar

Start the bundle

start BUNDLE_ID
inspect capability service BUNDLE_ID
inspect requirement service BUNDLE_ID

Install and start the bundle

start http://central.maven.org/maven2/org/apache/felix/org.apache.felix.gogo.runtime/1.0.0/org.apache.felix.gogo.runtime-1.0.0.jar

Install and start the iPOJO-related commands

start http://central.maven.org/maven2/org/apache/felix/org.apache.felix.ipojo.gogo/1.12.1/org.apache.felix.ipojo.gogo-1.12.1.jar
help

ipojo:factory
ipojo:handlers
ipojo:instance
ipojo:instances
...
ipojo:components
ipojo:component hello.server.HelloComponent
ipojo:instances
ipojo:instance hello.server.HelloComponent-0

Change the name of the instance of the component by "hello-english" in the @Instanciate annotation in src/main/java/hello/server/HelloComponent.java

Rebuild and update the bundle

ipojo:instances
ipojo:instance hello-english

For the exam : What is the role of a handler in the iPOJO component model ? (link)

List the deployed handlers

ipojo:handlers

Deploy more handlers

start http://central.maven.org/maven2/org/apache/felix/org.apache.felix.ipojo.handler.eventadmin/1.8.0/org.apache.felix.ipojo.handler.eventadmin-1.8.0.jar
start http://central.maven.org/maven2/org/apache/felix/org.apache.felix.ipojo.handler.whiteboard/1.6.0/org.apache.felix.ipojo.handler.whiteboard-1.6.0.jar

ipojo:handlers

3) Add a HelloService service to the component

Add a HelloService interface in the package hello.service with one public method String sayHello(String name) { ... } in src/main/java/hello/service/HelloService.java

(You can see an example here)

package hello.service;

public interface HelloService {

        public String sayHello(String name);
}

Complete src/main/java/hello/server/HelloComponent.java in order to implement the HelloService

package hello.service;

public class HelloComponent implements hello.service.HelloService {

        public HelloComponent() {
                System.out.println("Hello hello_server");
        }

        public String sayHello(String name) {
                return "Hello" + name + " !";
        }
        
}

4) Deploy the server bundle and inspect the provided service

update BUNDLE_ID
headers BUNDLE_ID

What is the matter ?

Modify the bundle.properties file

private.packages=hello.server
import.packages=*
export.packages=hello.service

update BUNDLE_ID
headers BUNDLE_ID

inspect capability service BUNDLE_ID
inspect requirement service BUNDLE_ID

5) Complete the service interface and the implementation to the server component

Add a @Property field for the "lang" service property (The documentation is here)
Add @Validate and @Invalidate annotated methods (starting() and stopping())

Note : iPOJO annotations are documented here

mvn clean install

update BUNDLE_ID
headers BUNDLE_ID

inspect capability service BUNDLE_ID
inspect requirement service BUNDLE_ID

6) Create 1 bundle containing a client component

Generate the bundle skeleton with the iPOJO archetrype


mvn archetype:generate -DarchetypeGroupId=org.apache.felix -DarchetypeArtifactId=maven-ipojo-plugin -DarchetypeVersion=1.12.1

Define value for property 'groupId': : hello
Define value for property 'artifactId': : hello_client
Define value for property 'version':  1.0-SNAPSHOT: : 0.1.0-SNAPSHOT
Define value for property 'package':  hello: : hello.client

cd hello_client
mvn clean install

7) Modify the client component for invoking the sayHello() of the server component

Modify the src/main/java/hello/server/HelloComponent.java for invoking the sayHello() of the server component (The documentation is here)

(Hint: instanciate a thread during the @Validate method and stop the thread during the @Invalidate method)

(You can see an example here)

???

8) Modify the @Requires annotation of the client component

Modify the @Requires annotation of the client component in order to filter only french-spoken HelloService (The documentation is here)

(You can see an example here)

???

8) Create more instances of the hello server components

Create (ie instanciate) more instances of the hello server components in separate bundles. Each service had a "lang" property different for each bundle and containing a set of ISO 639-1 languages code (en, fr, en-us, en-gb, es, ... )

9) Create a new version of the HelloService interface

Create a new version of the HelloService interface (ie 0.2.0-SNAPSHOT) and its implementation.

package hello.service;

public interface HelloService {

        public String sayHello(String name);

        public String sayHello(String name, String lang);
}

Rebuild and deploy it.

update BUNDLE_ID /Users/YOUR_USERNAME/.m2/repository/hello/hello_server/0.2.0/hello_server-0.2.0.jar

10) Create a new version of the HelloService client

Create a new version of the HelloService client (ie 0.1.10-SNAPSHOT). The client component invokes the new method : sayHello(String name, String lang)

OpenHAB Event Bus Sniffer

Develop an iPOJO component (using the

@Component
@Instantiate
public class MyOpenHABBusSniffer {

    @Subscriber(
      name="myBusSubscriber",
      topics="foo")
    public void receive(Event e) {
