#15 Deploy flexjson as an OSGi friendly .jar file

[Anonymous]

Modify the flexjson packaging to add the appropriate lines in the MANIFEST.MF file so it can be deployed as an OSGi bundle.

[Roland Weiglhofer]

This should be done quickly. It is easy to implement. Just use the maven-bundle-plugin.

[Brandon Goodin]

Hey Roland. Thanks for the feedback. I'm aware of OSGi. But, I have never had to implement a system with it. So, I do not understand the requirements here. If it is easy to implement then it would be most appreciated if you could provide a patch on what we need to do. I currently have no need for this feature and do not possess the knowledge to implement this quickly. Unfortunately that means I am not going to implement it unless someone in the FlexJSON community provides a patch.

[Roland Weiglhofer]

Hi Brandon,
A requirement did/does not exist in most cases because many bundle repositories (eg Sonatype Nexus) automatically convert libraries to bundles. But there exist some repositories without this functionality and then this has to be done by hand.

ok...If I'll have time someday I'll create a patch for you.

[Brandon Goodin]

Is this all we need to do?

Hello Brandon,
yes it is!
Thx!!

[Brandon Goodin]

I ran the build locally and the MANIFEST.MF now contains the following. If this looks correct I'll go ahead and commit the changes to SVN.

Oh no sorry. You miss something. You have to export the packages.

[Roland Weiglhofer]

ok ... thats correct I think! I see no errors in the manifest.

[Roland Weiglhofer]

Thx

[Brandon Goodin]

Committed it to trunk. I'll see what I can do about getting a SNAPSHOT build out at some point.

[Roland Weiglhofer]

ok. thx.

[Brandon Goodin]

SNAPSHOT is available here if you would like to try it out. This change will go out in the next release.
