Hi,

I am facing an issue i created a project of maven archType10 in eclipse and when i upload the bundle on felix console it does not show the service registered over there below is the code what i wrote and screenshot of the bundle on felix,

MyService.java (Interface)

package com.aem.community.core.services;

public interface MyService {

  public String helloWorld();

}

MyServiceImpl.java (class implementing Interface)

package com.aem.community.core.servicesImpl;

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

import com.aem.community.core.services.MyService;

import aQute.bnd.annotation.component.Component;

@Component(immediate=true)

Hi,

Not pretty sure, but can you just try with "@Service({MyService.class})" instead of @Service(value=MyService.class) and see if it helps.

Is your bundle started?

Can you go to services in the OSGi console, and see if you have more info there?

[shubham250894]

I can only see the below services,

the service i created is not there, hence it is giving null pointer exception

[shubham250894]

yes bundle is started, Also, i can find my package name in MANIFEST info.

Try this article - its only the bundle and the JSP that invokes it.

Hi Shubham

          Please provide below details

1. Please check if the bundle is active. Please check the below screenshot for reference.

   If it is installed or in registered state , then check the cause of unresolved bundle

2. If your bundle is active, just check your logs and see if any information is available which says a conflict for the service.

3. Could you please provide the error log you see in your screen , because the screenshot you provided didn't give much insight on your issue.

          I did try your code snippet and I could see the service is registered. Providing the screenshots below for your reference

     My bundle is active and the service is showing up . I doubt there could be some other issue with your code, which can be figured out through the error logs

Thanks

Veena

hi smacdonald,

Thanks for the help

[shubham250894]

hi cquser1,

thanks for your concern but it didn't worked

[shubham250894]

Hi Veena,

I cannot see anything like conflicting service in error log, should i give you the screenshot of the logs created after reloading the page ?

[shubham250894]

Hi Veena,

I got this in error log. Red marked logs says it is registered.

in error log i cannot find my service at all

[Feike_Visser1]

Taking a step back, what exactly is the errormessage?

You posted a screenshot, but I can't see the errormessage there.

[shubham250894]

[Feike_Visser1]

thanks for this.

Can you confirm in your code, that indeed the service null. Thus causing the NPE.

[Feike_Visser1]

Also check in /system/console/components and see for more info there.

[shubham250894]

yeah the service is null

[shubham250894]

[Feike_Visser1]

What do you see when you open the details?

[Feike_Visser1]

Also I don't see "MyServiceImpl" in this list.

[shubham250894]

Yes there is no MyServiceImpl but Why ?
