Re: [ecf-dev] [Gsoc][ECF Tooling]-Generate codes for Service Registratio

Hi Markus / Wim

"org.eclipse.osgi.util ManifestElement" using this we can read the all elements but couldn’t find a way write into the MF, also this class has private constructor so cannot extend any more.

I went through the PDE classes , PDE manifest editor does not have any APIs to do this as I understood it uses very low level file writing method to this also those are eclipse internal packages.

Finally I decided to write my own API for this, I used both  "java.util.jar.Manifest", "org.eclipse.osgi.util.ManifestElement" to write my method, But some times there are formatting issues(but does not effect the MF functionalities or no errors) ,I think those are coming from jar.Manifest APIs , any way it's seems me, it is working properly.

Please have a look[1] and reports improvements and bugs if exists

@Markus

PS:- I am doing final phase of code re-factoring now , I can finish all these within today and will submit the code for final evaluation

Thanks and Regards

Hi, Take a look at the you can use the org.eclipse.osgi.util ManifestElement. Some usage example is here:

A property file is only read one during application startup. Changes
done to it during runtime won't result in your code picking it up
automatically.
Anyway, a property file is good enough for the moment.

Do not modify the MANIFEST.MF manually. JDT/PDE should have support for.
Use the Manifest editor as an example how it is done.
