Hi Christian,

I did succeed on deploying a network server bundle on OSGi.
To build it I did the following things,

In the maven I just include

        <dependency>
            <groupId>org.apache.derby</groupId>
            <artifactId>derby</artifactId>
            <version>${derby.version}</version>
        </dependency>
        <dependency>
            <groupId>org.apache.derby</groupId>
            <artifactId>derbynet</artifactId>
            <version>${derby.version}</version>
        </dependency>

And in the building process I put :

            <plugin>
                <groupId>org.apache.felix</groupId>
                <artifactId>maven-bundle-plugin</artifactId>
                <version>2.1.0</version>
                <extensions>true</extensions>
                <configuration>
                    <instructions>
                        <Bundle-Name>${pom.name}</Bundle-Name>
                        <Bundle-SymbolicName>${pom.groupId}.${pom.artifactId}</Bundle-SymbolicName>
                        <Bundle-Activator>com.francetelecom.minelia.derby.Activator</Bundle-Activator>
                        <Import-Package>org.apache.xalan.serialize;resolution:=optional,
                            org.apache.xalan.templates;resolution:=optional,
                            org.apache.xml.utils;resolution:=optional,
                            org.apache.xpath;resolution:=optional,
                            org.apache.xpath.objects;resolution:=optional,
                            org.w3c.dom, org.xml.sax,
                            javax.*;resolution:=optional,
                            org.osgi.framework,
                            org.osgi.util.tracker</Import-Package>
                        <Export-Package>org.apache.derby.jdbc, org.apache.derby.drda</Export-Package>
                        <Private-Package>org.apache.derby.*;-split-package:=merge-first, YOUR_PACKAGES</Private-Package>
                    </instructions>
                </configuration>
            </plugin>

The trick is two fold. Firstly, some imports are optional like the xalan serializing process etc... But the main problem is that some packages are split in the jar derby and derby net. No you have to do merge-first strategies.
By the way, it is a bit weird to have split packages in the derby distribution.

Hope this helps :)

Hi All,

I have problems running derby with network connector in an OSGi environment.

I created my own bundle for the starter and use an Activator to start derby (see below).
I have also attached to Manifest of my bundle. Probably there are more imports missing but this is as far as I got.

To install all this I use Karaf and a feature file (see below).

The derby jar seems to bea bundle already so I simply install it from maven. The derbynet jar is no bundle so I use the wrap syntax of Karaf so a Manifest is created for it on the fly.

So the problem is that when I install a bundle I get a non resolvable import
Error executing command: The bundle "derby-starter_4.1.0.SNAPSHOT [159]" could not be resolved. Reason: Missing Constraint: Import-Package: org.apache.derby.iapi.tools.i18n; version="0.0.0"

The package is in the bundle derby but it is not exported.

So I think either that export and perhaps some more is missing or I am doing something wrong.

Can anyone help me with this?

If you want to test this yourself I can provide a complete maven project and some instructions.

Christian

Feature file for Karaf
--------------------

<feature name='tesb-derby-starter' version='4.1-SNAPSHOT'>
<bundle>mvn:org.apache.derby/derby/10.8.1.2</bundle>
<bundle>wrap:mvn:org.apache.derby/derbynet/10.8.1.2</bundle>
<bundle>mvn:org.talend.esb/derby-starter/4.1-SNAPSHOT</bundle>
</feature>



-------------------------------
Starter class
-------------------------------
package org.talend.esb.derby.starter;

import java.net.InetAddress;

import org.apache.derby.drda.NetworkServerControl;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;

public class NetworkActivator implements BundleActivator {
    NetworkServerControl server;

    public void start(BundleContext context) throws Exception {
        server = new NetworkServerControl(InetAddress.getByName("localhost"),1527);
        server.start(null);
    }

    public void stop(BundleContext context) throws Exception {
        server.shutdown();
    }

}
