How to build a Tuscany OSGi environment?
I'm trying to build a Tuscany environment that includes some of the
latest Tuscany OSGi integration.
My use case is that I want Tuscany to bootstrap OSGi for me when I start
a Tuscany node, as it'll help the node load different levels of runtime
extension and dependency bundles. I want to start with Equinox for now
(I'll test with Felix later).
I have some questions:
What Tuscany modules do I need to add to my POM as dependencies?
What's the difference between modules extensibility-osgi and
extensibility-equinox?
What are these two modules responsible for?
node-launcher-osgi has a compile dependency on Felix, can this
dependency be pushed to another module?
Shouldn't the dependencies on the OSGi JARs in node-launcher-osgi have
scope 'provided' instead of 'compile'?
Thanks

Hi,
If you configure your project with tuscany-maven-osgi-plugin, the plugin
will look at the set of dependency jars for the project, some of them are
tuscany modules (which are already OSGi bundles) and the others are 3rd
party jars. The plugin will start the OSGi runtime, create bundles out of
the 3rd party jars and install them with the tuscany bundles into OSGi, then
use the SCANodeFactory from the OSGi to run the test cases.
Thanks,
Raymond

That question remains as it got skipped in the previous exchanges.

Thanks a lot, that's what I'm going to use for testing now.

Not surprising as this thread is not discussing that :) it's discussing
how to build it.

Hi Raymond,
Would it be possible for you to create a wiki page that documents how to
use Tuscany with OSGI and we'll link to it from user documentation? I read
this thread multiple times to see if I can do it and I don't think I have
enough info.
Thanks,

Equinox. It requires:

common-3.3.0-v20070426.jar

OK Thanks, I'd like to simplify a bit and not require the
-Djava.ext.dirs=.\tuscany\launcher part. I'll look into the launcher
code to see if that can be done.
I'll add tuscany-extensibility-osgi to the test distro too.
Question (2) remains: What is the equivalent list of JARs for Equinox?
Any idea?

Re: How to build a Tuscany OSGi environment?
Posted by Raymond Feng <en...@gmail.com>.
I see two lists here:
1) A list of jars required to run the node-launcher-osgi (assuming it's
under tuscany\launcher)
tuscany-node-launcher-osgi-1.4-SNAPSHOT.jar
org.apache.felix.framework-1.0.4.jar
org.osgi.compendium-1.0.1.jar
org.osgi.core-1.0.1.jar
org.osgi.foundation-1.0.0.jar
servlet-api-2.5.jar
2) A list of OSGi bundles required to start a SCA node (assuming it's under
tuscany\modules or tuscany\lib)
This varies depending on what extensions are required. This can be one of
the distros + tuscany-extensibility-osgi-1.4-SNAPSHOT.jar (if not added to
the distro)
Then we could run the following command:
java -Djava.ext.dirs=.\tuscany\launcher -DTUSCANY_HOME=.\tuscany -jar
.\tuscany\launcher\tuscany-node-launcher-osgi-1.4-SNAPSHOT.jar ...
Thanks,
Raymond

AFAIK no Tuscany distro includes node-launcher-osgi at the moment, so

Did that, I get that list of JARs:
tuscany-extensibility-osgi-1.4-SNAPSHOT.jar
tuscany-node-launcher-osgi-1.4-SNAPSHOT.jar
org.osgi.core-1.0.1.jar
org.osgi.compendium-1.0.1.jar

Sorry, I'm having trouble understanding what that means. Aren't the
Tuscany JARs OSGi bundles already?

I know, I'm trying to help with ideas too, but to help I need answers to
my simple questions :) I'm going to try to ask my question again
differently, hoping it works this time.
1) Is this list of JARs:
tuscany-extensibility-osgi-1.4-SNAPSHOT.jar
tuscany-node-launcher-osgi-1.4-SNAPSHOT.jar
org.osgi.core-1.0.1.jar
org.osgi.compendium-1.0.1.jar
org.osgi.foundation-1.0.0.jar
org.apache.felix.framework-1.0.4.jar
the minimum set of JARs needed to an OSGi-enabled Tuscany node / Felix?
2) What is the equivalent list of JARs for Equinox?

Re: How to build a Tuscany OSGi environment?
Posted by Raymond Feng <en...@gmail.com>.
There are a few options on the table now:
1) Unzip one of the binary distros from Tuscany into TUSCANY_HOME
2) Use maven dependency plugin to copy project dependencies to TUSCANY_HOME
(see the node-launcher-osgi/pom.xml).
PS: If you use our tuscany-maven-osgi-junit plugin, it will create the
bundles automatically from the maven dependency list.
3) Rajini recently added a module [1] which will produce a fat jar file
which contains all the tuscany and 3rd party bundles on the dependency list.
We might be able use it to produce an OSGi-enabled tuscany distro.
[1]
https://svn.apache.org/repos/asf/tuscany/java/sca/itest/osgi-tuscany/tuscany-versioned
4) Explore the possibility to use the Eclipse Equinox run/debug profile to
launch Tuscany inside OSGi.
We don't have a very good story yet. Any ideas are welcome.
Thanks,
Raymond

Right, but before they get found under TUSCANY_HOME, somebody has to put
them there... I'm that guy at the moment, trying to copy the JARs under
my TUSCANY_HOME, and my question is: which JARs do I need to copy?

We have both Equinox and Felix. Felix is better tested ATM.

If you use tuscany-node-launcher-osgi to launch the node, you will need to
have dependencies to compile your app (such as sca-api and node-api). The
other tuscany and 3rd party runtime jars (bundles) will be discovered from
TUSCANY_HOME and TUSCANY_PATH system properties or environment variables.

extensibility-osgi use the OSGi bundles to discover tuscany runtime
extensions/extension points using the META-INF/services pattern.
extensibility-equinox is added as a place holder to support Eclipse
plugin.xml based extension/extension point registry. So far it's still
pretty much the same as extensibility-osgi.

I'm struggling a bit here on where we should provide the pluggability for
OSGi runtimes such as Equinox or Felix. There are a few options:
1) Have different OSGi launchers for Felix and Equinox
(tuscany-node-launcher-osgi uses Felix at this point)
2) Define a SPI to discover OSGi runtimes based on the service discovery
pattern (maybe go into the extensibility-osgi, but it's kind of chicken-egg
issue. The full tuscany runtime service discovery will only be available
once the tuscany runtime is bootstrapped into the OSGi).
3) Use brute-force to see which OSGi runtime is on the classpath (See
tuscany-osgi-runtime module)

It could be. What would be the user experience to use the launcher? If we
use a command line to launch the OSGi node. Then the less jars are required
for the launcher, the better. Maybe we should have a "launcher" folder under
TUSCANY_HOME to contain a small set of jars for the purpose of launching.

In SVN r689576 I've started to add some of the OSGi modules to a distro
build to enable some testing. I still have the above questions though.
