eqinox to felix - an experience

The other day I had created a few OSGi bundles in Eclipse and deployed the same in the Equinox framework of Eclipse..

These same bundles when I deployed in Felix.. it gave an error stating it was not able to find the classes .. esp those which were exposing the services.Next I added the following bundles in the manifest of each of the bundles:

- javax.naming
- javax.naming.event
- javax.naming.spi


And VOILA !!! it worked .... :-)

My first OSGi bundle

I have shown below some basic steps in creating an OSGi bundle in Eclipse.

Step 1) First open your Eclipse IDE , right click on your package explorer and choose New---> Other





Step 2)Select Plug-in Project under the Plug-in Development Header.





Step 3) A new Plug-in Project window will open , beside the project name tab write my.first.bundle then click next.




Step 4) A new window appears as :



click Next


Step 5) Select the Hello Osgi Bundle template and click Finish.



Congrats your first bundle has been created

Step 6)Now to run the same... Right click on the bundle , go to Run Configurations



Step 7) Select the Osgi framework and right click on the same and click on new-> run








Once done ,now you should be able to see:

osgi> Persistence bundle starting...
Persistence bundle started.
Hello World!!



This was a basic and simple way to create and deploy a bundle in Eclipse... lots more in the making ...till then
Try this out !!!
