FrameworkEvent ERROR on running a Hello World OSGI Bundle

Question

I am a beginner in OSGI. I followed the following tutorial to do a simple Hello World OSGI Bundle in eclipse. http://www.javaworld.com/javaworld/jw-03-2008/jw-03-osgi1.html?page=2

On running the project, I receive a bunch of errors in the console. Below are these errors:

and other similar errors....

Can you please help me to fix this? Thank you.

Answer 1

I struggled a lot for “Workbench has not been created yet” the complete day.

But I got the solution by the following steps.-

1. Go to the Run configuration -> Remove all the target platform jars.
2. Click on add required bundles.
3. Check the org.apache.felix.gogo.runtime, org.apache.felix.gogo.shell, org.eclipse.eqinox.console, org.eclipse.osgi and your jar file.
4. The last and important step. Go to Setting-> check the checkbox of "Clear the configuratation area before launching".
5. Run the OSGi application now.
6. Enjoy if it works for you as it worked for me.

Thanks
