Publishing OSGI Service with Fabric

[aunlu]

Hi,

I am trying to publish an OSGI service in a Fabric cluster. I am using jboss-fuse-6.1.0.redhat-379. Container profiles are based on predefined jboss-fuse-medium profile.

I added "service.exported.interfaces" as described in https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Fuse/6.1/html/Fabric_Guide/files/Arch-Discovery.html.

But, org.osgi.util.tracker.ServiceTracker running in a remote container cannot see that service.

1. Is there a sample code for publishing service in fabric?

2. How can i lookup fabric registry if osgi service is registered ?

3. Does service tracker work in fabric as expected?

Thanks,

Here is a blueprint example:

Exposing a service:

<?xml version="1.0" encoding="UTF-8"?>

<blueprint

       xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"

       xmlns:enc="http://karaf.apache.org/xmlns/jasypt/v1.0.0"

       xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.1.0">

    <bean id="dbcp_pool" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

        <property name="driverClassName" value="$(db.driver)"/>

        <property name="url" value="$(db.URL)"/>

        <property name="username" value="$(db.user)"/>

        <property name="password" value="$(db.password)"/>

        <property name="initialSize" value="$(db.initial)"/>

        <property name="maxActive" value="$(db.max)"/>

        <property name="validationQuery" value="$(db.validationQuery)"/>

        <property name="connectionInitSqls">

            <list>

                <value>ALTER SESSION SET CURRENT_SCHEMA=$(db.schema)</value>

            </list>

        </property>

    </bean>

    <service interface="javax.sql.DataSource" ref="dbcp_pool">

      <service-properties>

            <entry key="osgi.jndi.service.name" value="jdbc/datasource"/>

      </service-properties>

    </service>

Consuming a service from another bundle (pay attention to ext namespace, version is important):

<blueprint

        xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"

        xmlns:enc="http://karaf.apache.org/xmlns/jasypt/v1.0.0"

        xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.2.0"

        xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.3.0"

        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        xsi:schemaLocation="

              http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd

              http://camel.apache.org/schema/blueprint http://camel.apache.org/schema/blueprint/camel-blueprint.xsd

              ">

    <reference id="datasource" ext:filter="(osgi.jndi.service.name=jdbc/datasource)" interface="javax.sql.DataSource"/>
