Error when trying to consume OSGI Service

Avatar

Level 2

Hi Everyone,

This is my first post after attending the developer and advanced developer courses on CQ5.5.  Everything has been fine up to the point where I am trying to create and consume an OSGI service but am receiving an error.  I was hoping someone could help?

I have created a bundle which has an interface (RepositoryService) and implementation (RepositoySeviceImp) .  I have modified the bnd file to export my package:

Export-Package: com.adobe.training

Import-Package: *

Private-Package: com.adobe.training.impl

# Include-Resource:

Bundle-Name: my training bundle

Bundle-Description: NA

Bundle-SymbolicName: com.adobe.training.hellobundle

Bundle-Version: 1.0.0-SNAPSHOT

Bundle-Activator: com.adobe.training.Activator


Everything looks fine in the OSGI console.


I then try to consume the service in my jsp:

<%com.adobe.training.RepositoryService repositoryService = sling.getService(com.adobe.training.RepositoryService.class);%>

<%= repositoryService.getRepositoryName()%>

However the repositioryService is null and causes the following exception..  I guess sling cannot find the class but I dont understand why?

In your jsp you are binding into implementation class "HelloWorld"  instead use the interface "CustomerService"

Hello,

As you mentioned everything looks good in OSGI console but when sling returns null for any service call it means either the service is not deployed correctly or its deployed but not in active state because of some reason. I hope the proper import of service package you have done in your jsp.

There is similar type of issue posted in forum and we suggested couple of quick check. If you can just recheck those thing in your environment i hope will get answer to you problem most probably

Refer this - http://forums.adobe.com/thread/1172077?tstart=0

If after going through above it doesn't resolve then let use know and also send your service classes.

Thanks,

Hi Pawan,

Thank you for the reply for the reply and Ive looked at the thread as suggested but still to no joy 😞

Here is my Service classes:

Interface

package com.adobe.training;

public interface RepositoryService {

    public String getRepositoryName();

}

Implementation

package com.adobe.training.impl;

import com.adobe.training.RepositoryService;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.apache.felix.scr.annotations.Component;

import org.apache.felix.scr.annotations.Activate;

import org.apache.felix.scr.annotations.Deactivate;

import org.apache.felix.scr.annotations.Service;

import org.apache.felix.scr.annotations.Reference;

import javax.jcr.Repository;

@Component(metatype = false)

@Service(value = RepositoryService.class)

public class RepositoryServiceImpl implements RepositoryService {

    private static final Logger LOGGER = LoggerFactory.getLogger(RepositoryServiceImpl.class);

    @Reference

    private Repository repository;

    public String getRepositoryName() {

        return repository.getDescriptor(Repository.REP_NAME_DESC);   

    }

    @Activate

    protected void activate() {

      LOGGER.info("service activated" );

    }

    @Deactivate

    protected void deactivate() {

        LOGGER.info ("service deactivated");

    }

}

Activator

package com.adobe.training;

import org.osgi.framework.BundleActivator;

import org.osgi.framework.BundleContext;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

public class Activator implements BundleActivator {

    private static final Logger LOGGER = LoggerFactory.getLogger(Activator.class);

    /*

     * (non-Javadoc)

     * @see org.osgi.framework.BundleActivator#start(org.osgi.framework.BundleContext)

     */

    public void start(BundleContext context) throws Exception {

        LOGGER.info("bundle started");

    }

    /*

     * (non-Javadoc)

     * @see org.osgi.framework.BundleActivator#stop(org.osgi.framework.BundleContext)

     */

    public void stop(BundleContext context) throws Exception {

        LOGGER.info("bundle stopped");

    }

}

My Config

Hi Pawan / everyone,

Further to this I tried to activate my component using (immediate =true) and I received the following error. I think this may be why sling cannot retrieve the object…  Am I missing some dependencies / config or something?

After some digging around I found this: https://issues.apache.org/jira/browse/FELIX-3568

This relates to java 1.7 however I am running java 1.6.0_29.

As stated I changed the VM option and it has worked!

Im still unsure what the problem was and how the VM option has fixed it and was hoping someone could help me understand this?

Hi CQDarren,

How did you change the VM options?

Level 2

Hi Harrishmv,

You have two ways

1) In your CQ installation you will have a quickstart.bat and you can apply vm args thier..  i.e  "set CQ_JVM_OPTS="

2) You can add the vm options to the cq executable jar using ergonomics e.g -Dxx:useSplitVerifier

I would do it in the quickstart.bat..  Saves you configuring each time..

Hope it Helps

In your jsp you are binding into implementation class "HelloWorld"  instead use the interface "CustomerService"
