I've read in the documentations of Apache Ace 2 that it works with Equinox OSGi targets as well, but I can't find out how to configure it. I am aware there is already p2 for Equinox but I also want to integrate it with the Ace software.
I've found somewhere that I should edit managementagent bundle, if that's true still don't know how.
The binary release of Apache ACE ships with:
An executable jar that contains Apache Felix and the management agent. It can be found in the server-allinone/store folder and is called ace-launcher.jar
A "development" target in the target/ folder that can be used to for development/testing and pre-installs a shell, logging and the management agent.
Neither gives you Equinox out of the box.
However, if you checkout the ACE sources, there is a project called org.apache.ace.agent.launcher which creates two jar files:
felix.bnd which creates the ace-launcher.jar mentioned above and embeds Apache Felix
base.bnd which relies on the standardized launcher API of OSGi and will bootstrap the first framework it finds on the classpath
So, you can either use the artifact generated by base.bnd and put Equinox on your classpath, or take felix.bnd and modify it so it will run equinox instead.
By the way, we would be happy to accept such work as a patch so we can provide this out of the box.

I'm just starting to develop a new eclipse plugin where I want a web application server running in Eclipse. I found a nice blog, OSGi as a Web Application Server, that describes how to do this. The author suggests creating a target environment for my bundle requirements, and some of those bundles get pulled in from the Equinox Project SDK (now called Equinox Target Components in Juno). I notice that the tutorial project runs fine when my target platform is the platform I created in the tutorial, but fails to start when it is the default platform. So, now for my question...
If I need bundles that are not part of the default, how will my plugin project get access to those bundles? Will I need to deploy them along with my plugin? How would I know if the user's eclipse does or does not already have those required bundles?
You was not much clear about what kind of application you are developing. Running a web server in an Eclipse IDE as a plugin don't make any sense to me. This kind of server application is best just running on top of Equinox.
Anyway, the right path is to create a "Product Configuration" file and add categories that contains the needed bundles (go to File/Plug-in Development/Product Configuration).
With this file you can run an instance of the product (inside the IDE) and can export it (create a zip containing all needed bundles)
And if you want to able your user to install plugin inside his IDE you must create a P2 repository (using a Target Definition File) and expose the exported directory within a Http server. You could research about Tycho to build this kind of components in a maven style.
Well, I'm not sure if re-inventing the wheel again is really sufficient.
You might take a look at Pax-Web for inspiration on how to do it, or take a look Apache Karaf as a OSGi-Container (using Pax-Web). Or even better start contributing to one of the two :-)
I have an Eclipse Feature that I'm building that contains a few plugins. One of the plugins uses the import package statement to declare a dependency on another plugin.
The other plugin has platform specific code and exists in another feature that I'm building. I have two plugins in this feature that have the platform specific code. One for os=win32 arch=x86 and the other for os=win32 arch=x86_64
Both features are being built and using Tycho and they both have p2 repositories that are successfully available.
So, I made a composite repository that points to both of these repositories, and then I use the "Install New Software..." command in my RCP app and point to the composite repository to install the first feature I mentioned.
The issue is that when the installation is done, the plugin that has the platform specific code has failed to install correctly. Specifically, the plugin for the x86 system shows up on my 64bit machine.
In your feature.xml, choose the plugin with platform specific code and add a platform filter. the filters are available on the right side (once you select the plugin). You can choose filters such as:
OS
WS
Language
Architecture
When your feature is published, p2 will generate the appropriate filters.
I found the answer.
I needed a p2.inf file sitting next to my feature.xml file in the first feature I mentioned in the question.
And in that p2.inf file, I needed this text...
requires.1.namespace=org.eclipse.equinox.p2.iu
requires.1.name=com.myplatform.specfic.bundle.win32.x86
requires.1.filter=(&(osgi.os=win32) (osgi.arch=x86))
requires.1.namespace=org.eclipse.equinox.p2.iu
requires.1.name=com.myplatform.specfic.bundle.win32.x86_64
requires.1.filter=(&(osgi.os=win32) (osgi.arch=x86_64))
I added this file to the build.properties as well to make sure it was included in the deployed feature
Then when I deployed the p2 repository and performed the install into my RCP application, the correct plugin was placed onto my 64 bit machine.
UPDATE: I was wrong here. This is NOT the correct answer. The incorrect plugin still gets installed on some machines.
I' starting to use ServiceMix and Camel and I've run through many examples.
It seems that the examples that are OSGi can be deployed in ServiceMix via hot deploy or via console, but I don't know how to deploy a project that is not an OSGI. Can it be done?
For example, I'm looking at the example project from Camel 2.10.0 called camel-example-cxf-proxy. I did some alterations and now I wanted to load it in ServiceMix. If I copy/paste to the deploy directory it is loaded but when I try to run it via osgi:start id it fails.
However if I run it from the IDE as a standalone it runs just fine and I can send and receive requests via SoapUI.
When I'm done with the examples I'll want to create my own project in eclipse and do tests in the IDE and in ServiceMix. I don't really understand the advantage of OSGi yet. SO I'm not too compelled to use OSGi for my project.
My main question is: Can I deploy a non-OSGi non-JBI compliant project in servicemix? Something like the camel-example-cxf-proxy. If yes, how can I do it? If no, how can I OSGi-fy the camel-example-cxf-proxy?
Thank you :)
Apache ServiceMix which uses Apache Karaf as its kernel, support pluggable deployment units. Though OSGi is the main unit.
You can deploy JBI artifacts (eg JBI was used as deployment units for Apache ServiceMix 3.x). So we offer that as a migration path to run JBI in SMX 4.x.
A plain WAR file can be deployed as well. You can for example just drop a .war file in the deploy directory. If you deploy from the shell, you need to prefix the deployer with war so it knows to use the war deployer.
There is some documentation about the various pluggable deployers here
http://fusesource.com/docs/esbent/7.0/esb_deploy_osgi/UrlHandlers.html
For example to install an Apache Wicket WAR example using Maven you can do from the shell:
osgi:install war:mvn:org.apache.wicket/wicket-examples/1.4.7/war?Web-ContextPath=wicket
The Apache documentation about deployer is mainly documented at Apache Karaf
http://karaf.apache.org/manual/2.2.9/users-guide/deployer.html
Now to deploy OSGi applications can be a bit of pain to assemble. And that is why FuseSource created FAB to make it much easier. I blogged about this a bit, which references to videos and more material: http://www.davsclaus.com/2012/08/osgi-deployment-made-easy-with-fab.html
With FAB you can just deploy regular Maven projects out of the box without any OSGi pain.
If your project is a maven project, you can try :
mvn install
Then start your servicemix, and in servicemix command line :
install mvn:groupId/artifactId/version
This will prompt a bundle ID. Then, juste start the bundle :
start <bundle_id>
You can check the state of your bundle with command "list"
The project has to be a bundle to be installed in servicemix / karaf. So the steps to make a camel project work in OSGi are the following.
Use the maven bundle plugin in the pom and configure it to import / export the necessary packages if necessary.
Make sure your camel context is defined in a way that OSGi can start. This is either in the activator of the bundle or in a spring config in the right location or with a blueprint config in the right location.
See two of my karaf tutorials for the details:

I have a project that's using the Play framework, and the corporate standard is that all projects should be built by Hudson. However, I cannot find out how to do this, as Hudson does not follow any Java standards, and requires the framework installed at the computer it runs on. I have tried to build the project with Maven (if I had managed this, adding it to Hudson should be quite simple), but I have failed to make it work. I tried the Play Maven module, but Maven claims it does not find the external repo that is listed (http://nexus.infin-it.fr/content/groups/public). This might be because I am behind a firewall. I also tried the recipe listed here, but the local maven build fails because it is unable to find org.playframework:play:1.1:jar.
Has anyone done this and can provide a howto?
It can be done without installing the Play framework on the Hudson server, but it is quite complicated:
Put the play libraries (play.jar and its dependencies) in a Maven repository
Create a pom.xml for your project, configured with:
theses libraries as dependencies
your project specific dependencies (project lib directory)
the java sources folder of your project (in the maven-compiler-plugin): "app"
If your project is simple (no module dependencies), this pom allows you to build the play project java sources using Maven.
If your project has module dependencies, you will have to add the dependencies jar in your pom dependencies.
To do that, you will have to create jar files from the modules if they don't have packaged jars (to get the "CRUD" class of the CRUD module for example).
You can find some help on this page I wrote :
http://blog.infin-it.fr/2010/12/15/play-framework-integration-continue-retour-dexperience/
Even if it's in French, I put my Ant stuff and the Play's pom I wrote.
At work we managed to integrate our Play applications with Bamboo.
It should not be difficult with my files.
Just looked at the repository, that you linked (http://nexus.infin-it.fr/content/groups/public). And guess what, I found the play-1.1.jar. However, the artifact ID is: org.play:play:1.1:jar and not org.playframework
In theory, you could put the full Play zip on your build or in in your repository, and then use Hudson to kick off an Ant script to download Play to the Hudson agent, unzip it, and then run commands on it. It's a little clunky, but it should work.
I'm building my application to run in an OSGi container. I use Maven and the Maven Bundle Plugin from Apache Felix to set up the OSGi manifests for my own modules and that works great.
Now, I'm deploying my bundles into an OSGi container together with several 3rd party libraries. Some of these are already OSGi-fied when I get them from the Maven repos, others, I want to convert into OSGi-compatible jars. I want to set up a Maven project that collects all dependencies, and puts each in its own OSGi jar. The ultimate goal is to collect these jars and my own into an assembly that I can use as a standalone deployment package.
I know how to convert standard jars to OSGi jars, and I have a (somewhat hackish) approach to merge multiple OSGi bundles, even if I probably shouldn't. But if I have a dependency that's already fine as it is, and I just want to copy it from the repo into my assembly, what part of Maven do I use? The bundle plugin is wrong, it messes up the manifests if a dependency is already OSGi-compatible. Do I use the dependency-plugin, the assembly plugin or something else?
I have the feeling I'm overlooking something very simple here.
Did you have a look at the PAX tools? In particular Pax-Runner and
pax-construct... They do not only give you a nice template to start with, but also solve most the problems you mentioned for free.
We use many libraries which are not OSGified by the vendor and which are not available on the Spring bundle repository. We also have many of these and want to deploy them all together hassle free. For this we have created a 2-layer maven setup:
Individual maven projects that either download or contain (as 'system' scope depends) the 3rd party lib in question, and OSGify these using the Apache Felix bundle plugin
One container project that has a dependency on all of these small projects and makes an assembly of them using the core assembly maven plugin. This POM also uses the copy-dependencies goal of maven to make sure everything is in place.
Once it is turned into an assembly (ours is a tar file) we deploy this to our servers. We have gone one step further and used this assembly of 3rd party libraries as the Target Platform for our Eclipse build environment. But this may be irrelevant for you.
You can get OSGi friendly versions of many common artifacts from the Spring bundle repository. So you may not have to do it yourself.
See details of how to configure the bundle repository for Maven.
(will update with some ideas for those that aren't available as bundles already)
