Re: [ecf-dev] adding to RemoteServiceAdmin wiki docs

sorry for the misppell, I meant:

It seems that rsa try to discover an rs in the bad container, I mean it looks in the local container intead of remote, even if
it knows the rs containr id:

Hi Scott,

How to get the framework-uuid lauched by the host ?

On Equinox 3.7, the framework uuid can be gotten from this System property:  org.osgi.framework.uuid.  So,

String uuid = System.getProperty("org.osgi.framework.uuid");

should do it. 

For older versions of Equinox, the framework uuid wasn't/isn't set by the framework itself, so it can be necessary to create a uuid and *set* the system property...there's code to do this here [1]...in the getFrameworkUUID() method (this is used within the ECF impl of RSA for older versions of Equinox).



I ask that , because I would like to put this static in generic-hello.xml edef static bundle.
I have realized from your precedent post , that I should know that in advance and then set this property in the host ?

You can't/shouldn't set the framework uuid...unless it's not already set.  According to recent OSGi spec, the framework uuid should be set by the framework itself (and the code pointed to above is only for older versions of frameworks...that didn't set the uuid system property).

Note if you wish you can set some other service property and use that to filter on in the edef, but in general you shouldn't be modifying the framework uuid.

I was waiting for this improvement in the wiki to continue
investigating ECF usages. Maybe I would suggest code examples to bind
to specific services or similar.

Have you examined the 'hello' examples?  These support the usage of multiple/alternative discovery and distribution providers (e.g. zeroconf, zookeeper, slp, dnssd for discovery...r-osgi, ecf generic, jms, xmpp, rest, etc for distribution).

I'm not sure what you mean by 'bind specific services or similar'.



I'm still a bit confused about the
difference of a server/host URL and the containerFactoryArgs property,

ECF provider instances are created via a container factory...and each provider can optionally define an arbitrary array of arguments that is uses to initialize/configure the container instance upon creation.   The containerFactoryArgs property can be used to pass arbitrary arguments to the container factory...via the service properties passed to the service registration call.

The ECF generic provider takes a single argument that allows one to specify the server/host URI for that provider...with default of:

ecftcp://localhost:3282/server

Note that this is for the generic provider only...and other providers take other arguments (or take no arguments at all).   Each provider has it's own configuration requirements (and it's own expected/required set of containerFactoryArgs).

Note that if greater control over the container creation and selection process is desired, that one can simply register one's own implementation of the IHostContainerSelector [1] as a service, and then when the ECF RSA impl exportService call is made then the customized host container selector will be called to select (and optionally create/configure) the container(s) to actually export the service.  The default implementation of IHostContainerSelector (class HostContainerSelector[2]) is where the host/server container is actually created...and where the containerFactoryArgs are actually used/passed into the container creation.

My intention is to add to the RSA documentation to describe (with perhaps an example if I can manage the time) of creating/using a custom IHostContainerSelector (and IConsumerContainerSelector)...to show how this can easily be done...and allow the container creation, configuration to be customized as desired.



and how a client makes the discovery of services in an specific
computer. For example, code about list all the remote services in a
different machines than localhost could be interesting (without using
zeroconf, I mean).

This is as easy as adding an EndpointListener...with a scope that restricts the notification to the set of hosts that match...e.g. to frameworks that do *not* have the same framework uuid as localhost...e.g.

(!(org.osgi.framework.uuid=<your localhost framework uuid>)

You would register your EndpointListener with the endpoint listener scope (standard) property set...e.g.

Properties props = new Properties();
props.put(EndpointListener.ENDPOINT_LISTENER_SCOPE,"(!(org.osgi.framework.uuid=<your localhost framework uuid>)");
bundleContext.registerService(EndpointListener.class.getName(),new MyEndpointListener(),props);

I would like to have other/more examples of doing this (creating EndpointListeners with various kinds of scopes), and I've been contemplating an Eclipse view that shows all discovered EndpointDescriptions (with ability to easily set scope).  This would be easy to do...but alas no time.


I appreciate all the work of the ECF developers are doing, given that
they do in their spare time :)

Yes...see 'alas no time' comment above :).   If you can find non-spare time support, please consider making it known/available.

Hi all,

i am having trouble to get started with ecf in terms of setting my
development envitoment correctly
iso far i had alot of problems and exceptions thrown when starting the
platform
my guess i am missing dependencies or i didnt downlod the correct versions
for:

eclipse
OSGi
ECF

my goal is to be able to learn ECF capabilities and in the future even
contribute to the project

what is the correct profile/pre requisits for testing ECF?
what is the correct profile/pre requisits for developing ECF?

is there any step by step guide somewhere?

i am only getting started so please bare with me...

Hi Ronen,

We have documentation for starter contributor/user on installing the ECF sdk
at [0].
Also, I think you 'll need this at [1] also, which docs how to start rs use
with ECF implementation.

With that doc and... some resilience you'll get it!

The ECF download page [1] indicates that ECF 3.5 requires Eclipse Helios
SDK (3.6.X) or Eclipse Indigo SDK (3.7.X).    You can get Eclipse Helios
or Eclipse Indigo here [2].

what is the correct profile/pre requisits for developing ECF?
Same as above...i.e. Eclipse Helios or Eclipse Indigo....the SDK of
whatever version is best...because it includes most of the relevant
tooling, plus the Eclipse/Equinox source code (which can be useful).

In addition, since ECF now uses git for our repository [5], it's
necessary to use *some* git client...to retrieve and possibly change/add
to the latest ECF source.  The eGit client is popular (because it runs
in Eclipse) [6], but since it is not included in the Eclipse SDK you
need to install it into Eclipse SDK yourself.  See [6] for the
instructions for installing/using eGit.

You can also use other git clients if you wish (e.g. git command line
clients, etc)...but of course if you do so you have to keep your local
Eclipse workspace in sync with the local repo manually.


is there any step by step guide somewhere?
No...not one that includes installing Eclipse, eGit, etc.   If you want
to produce one...once you've identified the steps that will help
you...that would be a great contribution to ECF (i.e. by creating/adding
a page to the ECF wiki [3]).

However....we do now have several pages describing the
download/install/examples app usage for ECF's impl of OSGi remote
services (which is one part of ECF...not all of it, but one significant
part).  Those docs are here [4] (as indicated by Pierre's recent email
also).

As of ECF 3.5, much of ECF can/could run on Felix (another OSGi
framework impl), rather than only Equinox (which is an the OSGi
framework impl that comes *with* Eclipse).  Actually, I believe ECF
remote services development can/could probably be done by other
IDEs/tooling (e.g. Idea...and/or Netbeans), but I haven't even tried
this yet, so I can't explain the process for doing so.

Hi Folks,

I've been adding to the wiki-based docs for the ECF impl of the OSGi
Remote Service Admin (RSA) here [1].  The idea is to allow people to use
the major features of the ECF RSA impl without having to consult with
the OSGI specification (chap 122 of enterprise spec)...at least for
everything :).

It's not completed yet, but I would appreciate some review, as well as
comments or suggestions...or further contributions, examples, etc.

Thanks,

Scott

Add the org.eclipse.equinox.concurrent bundle to your runtime.
