org.eclipselabs.osgi.ds.annotations [message #549187]

Hi,

i spent friday night hacking around in the org.eclipse.equinox.ds
bundle. my target was to replace the current xml descriptor by an
annotation parser. result of this night can be viewed here:

http://code.google.com/a/eclipselabs.org/p/org-eclipselabs-o sgi-ds-annotations/

currently, there is no download available, since i am not familiar with
the process of contributing extensions for existing projects - without
hurting rules or similar.

so first of all i wanted to collect following information:

1. is there anybody who is interested into this project?

2. do i need to provide a project proposal?

3. would this be implemented into the org.eclipse.equinox.ds bundle
directly (like my current hack)?

4. i prefer a separate extension bundle. But as far as i can see, this
would require the implementation of proper extension points?
can i implement / contribute the code myself or will this be done by the
related project team?

best regards....

There has been a previous attempt at using annotations:

http://max-server.myftp.org/trac/pm/wiki/a4ds

Dealing with annotations becomes rather complex when there is an inheritance
hierarchy for the service component class.

Namaste, Bruce

Hi,

this project generates XML files by using an annotation parser as
eclipse builder. my project moves the xml completely out and parses the
annotations at runtime.

if you see the future plans described on my project site, inheritance
also should be no big deal if you can optionally specify the provided
services instead of parsing them automatically by included interfaces.
If i didnt get you, please send me more details about the possible problems.

Best regards!

I only briefly read your web page and didn't pick up that you were not going
to use XML files.
I agree that inheritance is unlikely to be a problem if you are doing it at
runtime.

In our situation the @Service annotation would definately be required as the
service component classes implement interfaces that should not be provided
as services.

The target attribute is also one that we use quite a lot to identify service
instances.

I would prefer to always use the manifest entry, rather than searching.

Namaste, Bruce
