SDK features

As discussed in the call today, I created features for the various SDK 
slicings of the Equinox world.  See

You should get the latest Equinox 3.5 bundles. The latest stable release is Equinox 3.5M6. I am afraid you will not be able to update only the two bundles because their requirements have changed and they will not run on Equinox 3.4. The best case would be to switch to Equinox 3.5 if possible.

I switched to Equinox 3.5M6 and I am no longer seeing the above problems. Thanks a lot.

BTW, When are you people planning to release Equinox 3.5.

Thanks

Hi Stoyan,

Here are the exact versions of the bundles I am using.

org.eclipse.equinox.ds-1.0.0.v20080427-0830.jar
org.eclipse.equinox.util-1.0.0.v20080414.jar

Can you please tell me versions of the bundle I should use in order to overcome this issue?

Thanks

Hi all

I am using Equinox Declarative Services implementation. When
my component gets activated, the “activate” method is
invoked on the component implementation class and that is
expected behavior. But the context class loader of the
thread which invoke the “activate” method is null. I am
having problems because of this. Is this the expected
behavior in the DS implementation? Any help would be greatly
appreciated.

Thanks

Re: Using Equinox Declarative services in another OSGI framework

Not sure if you did already but a bug report here would be useful. Anything that makes stuff easier to use is a good thing.

Thanx Stuart. That resolved the import problem so now DS is up and running (using the supplement bundle). In this case, as debug stuff is not so important and can work without debug stuff based on system params I would rather make the imports optional then having to bring in just another bundle to make it resolve. Even more in this case as the DebugOptions service is not there the supplement bundle is not of any use beside exporting the debug package. So, if I have the supplement bundle in I would expect that the supplement bundle is also publishing service implementations for the services it can, and this supplement bundle just has the classes (api + some impl) but not use them as there is no bundle activator. Could be that this (publish the services) is not possible outside Equinox system bundle, is that the case?

Hi Guys, I was trying to use Declarative Services implementation from equinox in another OSGi framework and looks like that is not possible. DS has an import on org.eclipse.osgi.service.debug;version="1.0" package that I could only find in the Equinox framework itself. Is it available from somewhere else?
Hi Alin, have you looked in the org.eclipse.equinox.supplement bundle? I'm using this to run the Eclipse extension point registry on Felix which also needs that debug import You can find releases of org.eclipse.equinox.supplement here: http://download.eclipse.org/equinox/ just pick from either the 3.4 / 3.5 stream
If not, can the org.eclipse.osgi.service.debug be made available at least as a separate bundle, even better together with DebugOptions impl? Another simpler option would be to make this import optional and handle the fact that package is not available in the DS Activator, case when DS can work as in case that no DebugOptions service is available = using system properties.

Device Access Howto?


Hi all,

I've embarked on a exploratory mission on the device access part for OSGi 4
with the goal of maybe getting a small/simple prototype up and running for
talking to devices over USB.

I've read through the specification but I'm just not able to wrap my head
around this thing and get a clear picture of how it is supposed to work...

Does anybody know of a "HelloWorld" and/or books on the subject?

Thanks

Re: Device Access Howto?

You may have better luck asking this question on the OSGi developers mailing list.

https://mail.osgi.org/mailman/listinfo/osgi-dev

There are a few books on OSGi coming out very soon but I am not sure they will include any examples of device access in them.

Reg : Loading bundles to OSGI framwork

Hi all ,
I am relatively new user of Equinox . I dont know whether the same question had been asked before or not .

In our project we intend to use Equinox . I would like to know what are the possible ways to load bundles into OSGI framwork .

I know we can use config.ini , Is there any other way to load a set of bundles to the framwork ? . To understand the technology better , we are not using Eclipse , for even gerenating Mainfest file . So apart from these options , is there any way to load a set of
bundles from a predefined location ( like can we have a bundle , which loads all other bundles ) ?? . Kinldy request you to give your comments.

Thanks in advance
Prasanna

Re: Reg : Loading bundles to OSGI framwork

To load a bundle programmatically, use the BundleContext APIs:

public Bundle installBundle(String);
public Bundle installBundle(String, InputStream);

Both APIs return a Bundle object, which you'll want to hold onto if you wish to be able to stop it at some time, but this is not absolutely necessary.

Please note that config.ini is not an OSGi mechanism, but something specific to Eclipse/Equinox.

Re: Reg : Loading bundles to OSGI framwork

Generally this is done by installing/starting a bundle which installs the rest of your bundles. This is what Eclipse does with the org.eclipse.equinox.simpleconfigurator bundle. This bundle understands the mete-data managed by the p2 management system in Equinox. But you don't have to use p2. You can develop your own simple bundle that installs bundles in what ever way you want. You can also look at something like file install from felix (http://felix.apache.org/site/apache-felix-file-install.html)

The config.ini file is used to configure your initial "boot" strap bundle so it can be installed and activated. But eventually you will want a more complete management story for your OSGi based product. When you get to that point I strongly encourage you to investigate using p2 in Equinox to manage your system.

HTH.
