After following the steps in the tutorial add your plugin, I typed in GSCL console ss, I found org.eclipse.om2m.sample.ipu in the console by 27 .
Although I created java activator class, Monitor, Mapper and controller as it is in the tutorial when I executed start 27 ,I find the error ' error loading bundle activator'
thank you to answer me.

Did you correctly import all required plugins (MANIFEST.MF) - "Add plugin dependencies"? Any errors in list (red X)?

Hi Wiem,

Try adding a "try catch" block for all Exceptions and print it in the start method of your plugin. When there is an error in the activator, the OSGi framework does not provide directly the stacktrace, you have to print it yourself (or look at the log file in the configuration folder).

And as Matej said, if there is a missing dependency it can create an error in the plugin.

Regards,
Fran├žois

Hello,

My goal is to manipulate phidgets by om2m interface, when I finished the tutorial add your plugin, I repeated it by replacing org.eclipse.om2m.sample.ipu by org.eclipse.om2m.ipu.phidgets and I added Activator.java classes Phidgets.java, PhidgetsMonitor.java, PhidgetsController.java which are in the file that mahdi ben alaya envoyed to me.
Then I connected my phidgets to my pc (temperatue sensor connected to phidgetsInter faceKit 8 / 8/8 ) .
In GSCL console by running start 25 I found those above
I want to know if the steps I followed were correct or not? otherwise how can I connect my phidgets to the platform om2m.

Thank you

I have the same problem (the error mentioned in the title of this topic). I made step-by-step screenshots of the procedure, by following the tutorial (in the form of .mht files, viewable by browsers).

Could somebody take a look at where I made a mistake? I am also attaching a better picture of the dependencies tab of the plugin.

Dear Klemen,

I appreciate your detailed description.

First remark: could you please put your new ipe plugin inside the folder "org.eclipse.om2m" in your git repository and then update your" pom.xml" file accordingly. Now your ipe plugin is created only only under your Eclipse workspace. It is important to have all the source file in the same location in order to avoid absolute links in your dependency.

Second remark: I see that the "Activator" class of your ipe plugin is not in the main "org.eclipse.sample.ipe" package. It seems to be in a separate folder having a similar name probably generated automatically by Ecipse when you created this plugin. Could you please move the activator with the other 4 classes and delete completely this second repository. Do forget to update the "Activator" path in the "MANIFEST.MF" file of your ipe plugin.

Hope this can help
Mahdi

Thank you for answering. The problem was the wrong location of the Activator class (after moving it to the src/main/java folder, to the other classes, things started working).
