Hi,

the last days, I tried to understand the NET4J framework, to implement
an own protocol.

Now I found one point, which I dont understand.
There are some factories and element processors, which a implemented
inside the org.eclipse.net4j.util plugin.

The factory will be registered but now inside the
org.eclipse.emf.cdo.server plugin

Exactly this are:

<extension point="org.eclipse.net4j.util.factories">
<factory
productGroup="org.eclipse.net4j.Negotiators"
type="challenge"
class="org.eclipse.net4j.util.security.ChallengeNegotiatorFactory"
/>
</extension>

and:

<extension point="org.eclipse.net4j.util.elementProcessors">
<elementProcessor
class="org.eclipse.net4j.util.security.ChallengeNegotiatorConfigurer"
/>
</extension>

Do this was forgotten and it is a bug, or is there a specific reason?

Greetings

Heiko

Hi Heiko,

Unfortunately I do not remember excatly why that has been changed. I think it was related with the fact that you normally want to provide your own implementations. Note that you can easily contribute the factories of your choice from your own bundle.

Cheers

Hi Eike
thanks for your answer.
I've looked into the old versions of net4j and CDO inside the svn
repository and since CDO 2.0 there are this combination.
If I do understand right the net4j framework with his IContainer system
and the factories, it is impossible to create a ChallengeNegotiator over
the container method

container.getElement(NegotiatorFactory.PRODUCT_GROUP, type, description);

as there will not used the cdo server plugin.

Greetings
Heiko
