Getting Started with iPOJO

Hi,

I can't seem to find a good article that will help me resolve the "getting started" issue I am facing.

I am using Eclipse Juno (4.2) on my Mac.

I have downloaded and installed the iPOJO eclipse plugin, from: http://clement.plop-plop.net/update/

I have created a sample project following the instructions at: http://felix.apache.org/site/ipojo-eclipse-plug-in.html

I have integrated Felix into Eclipse as a project, following instructions here: http://felix.apache.org/site/integrating-felix-with-eclipse.html

I have downloaded the following iPOJO bundle: org.apache.felix.ipojo-1.8.2.jar

I've launched Felix in the Eclipse console and I've installed the org.apache.felix.ipojo-1.8.2.jar bundle and started it.

I've created a test bundle using iPOJO called iPojoTest.jar and I've installed it and started it in the OSGI console.

I run bundles in the console and I get:

g! bundles

    0|Active     |    0|org.apache.felix.framework (3.0.7)

    1|Active     |    1|org.apache.felix.bundlerepository (1.6.2)

    2|Active     |    1|org.apache.felix.gogo.command (0.6.1)

    3|Active     |    1|org.apache.felix.gogo.runtime (0.6.1)

    4|Active     |    1|org.apache.felix.gogo.shell (0.6.1)

   12|Active     |    1|iPojoTest (1.4.0)

   13|Active     |    1|org.apache.felix.ipojo (1.8.2)


So, the bundle seems to have started.

But I don't get any console output from my sysouts…

Here are the start() and stop() methods:


 @Validate

    public void start() throws IOException {

                System.out.println("I'm starting...");

        try{

          // Create file

                  FileWriter fstream = new FileWriter("/Users/mcook008/out.txt");

                  BufferedWriter out = new BufferedWriter(fstream);

                  out.write("Hello Java");

                  //Close the output stream

                  out.close();

                  }catch (Exception e){//Catch exception if any

                  System.err.println("Error: " + e.getMessage());

                  }

        throw new IOException() ;

    }

    @Invalidate

    public void stop() {

        System.out.println("I'm leaving !");

    }




I added in the file write to see if a file would be created.  There is no file created.  So, while OSGi thinks the bundle is ACTIVE, the start method appears never have to been called.


Can anyone tell me what I may have done wrong or provide a clue as to what to look at to help diagnose the problem?


Thanks,

Mike

Hi Gokturk,

I had looked at the first URL when I was attempting to get my ancient
version of the Eclipse plugin to work.  I had first attempted to follow
its directions, but I received an exception when attempting to manipulate
the bundle.

Here's what I got:

Buildfile: /Users/mcook008/Documents/workspace/MyiPOJOBundle/build.xml

manipulate:
       [ipojo] Input directory :
/Users/mcook008/Documents/workspace/MyiPOJOBundle/bin
       [ipojo] Metadata file :
/Users/mcook008/Documents/workspace/MyiPOJOBundle/metadata.xml
       [ipojo] Start manipulation

BUILD FAILED
/Users/mcook008/Documents/workspace/MyiPOJOBundle/build.xml:54:
java.lang.ArrayIndexOutOfBoundsException: 8



On the second URL, it looks interesting, but there is insufficient
information on the page for someone without subject matter expertise to
understand how to configure it.

I have 15 years of Java programming experience, and I've been working with
OSGi for several years.  I'm very comfortable building my own manifests
and developing (I think) good OSGi code.  But there is a learning curve
associated with what I do, and I often work with others who don't have the
time to become expert in all things OSGi, so I was attempting to find out
if iPOJO might make it easier for me to teach them an easier way to
develop OSGi applications.  So far, it unfortunately appears that there is
more difficulty in trying to simplify the development process than there
is in the development process itself.

I'm likely missing something trivial and obvious to those who work with
iPOJO regularly, and my poor Eclipse environment is likely hopelessly
misconfigured from my failed attempts at finding the correct combination
of libraries.

I think maybe I'll stick with the "old fashioned" OSGi way, unless there
is a decent tutorial available which I can follow and learn the "correct"
way to work with iPOJO.  The funny thing is that a couple of years ago, I
had used Clement's old iPOJO plugin for a few projects, and it worked
easily.  That's what made me decide to try it again, but I can't repeat
the good results of a couple of years ago...

Thanks for all of the help.
Mike

Re: Getting Started with iPOJO

Posted by Göktürk Gezer <go...@gmail.com>.

Hi,

Yeah Michael is right, eclipse-ipojo-plugin is not updated since almost 4
years. And It's using ipojo-1.0.0 internally.

You should check
http://felix.apache.org/site/apache-felix-ipojo-eclipse-integration.html

You would also like
http://gitorious.ow2.org/ow2-chameleon/eclipse-ipojo-builder You can use
this plugin to integrate ipojo manipulation process right into eclipse's
own building phase and can use eclipse equinox launcher.

These would be necessary for you to build your own development environment
without so much burden.


Regards,
Gokturk

Re: Getting Started with iPOJO

Posted by Simon Chemouil <sc...@gmail.com>.

Michael,

Concerning iPojo itself, I think you won't find much tutorials outside
of iPojo's website. That website could definitely be improved and some
pages are outdated. I know iPojo is used in various companies, but
iPojo users are rather quiet compared to Guice or Spring/Blueprint
users who blog a lot more.

I suggest you take at look at the examples available at
https://svn.apache.org/repos/asf/felix/trunk/ipojo/examples/tutorial-maven
The samples are depending on iPojo 1.5.0-SNAPSHOT so be sure to update
the versions (in pom.xml files).

We switched to iPojo some time ago (from DS), and it was painless as
were already using Maven to build our projects. We simply had to
switch annotations and add the proper Maven configuration -- and then
benefit from all the other exciting features of iPojo.

There is a release coming soon that will fix a few bugs so in the mean
time we are following the trunk version. I suggest you take a look at
iPojo's JIRA if you encounter a bug during the build in the
maven-ipojo-plugin: if the bugs are marked as fix you will either have
to build your own local copy of iPojo (1.9.0-SNAPSHOT) or wait for a
release.

HTH,

Simon

Simon, 

Excellent. I will look online for tutorials explaining your suggested paths forward. If you know of any good ones, please let me know.

Subject: Re: Getting Started with iPOJO

Michael,

It seems like you are using an antique version of iPojo. The import
you show in your manifest is 0.9.0 and the last release is 1.8.2 (that
import is added by the manipulator).

In an earlier message you said you were using the Eclipse plugin
available on Clement's website. This plugin is not maintained anymore
and while there is a new iPojo Eclipse plugin maintained elsewhere, I
wouldn't advise using it. Rather, you should use the manipulator from
ant or maven depending on how you build your project. If you choose
the maven-ipojo-plugin, you can get decent Eclipse integration using
Maven's Eclipse environment (M2E).

HTH,

Simon

Re: Getting Started with iPOJO

Posted by Simon Chemouil <sc...@gmail.com>.

Michael,

It seems like you are using an antique version of iPojo. The import
you show in your manifest is 0.9.0 and the last release is 1.8.2 (that
import is added by the manipulator).

In an earlier message you said you were using the Eclipse plugin
available on Clement's website. This plugin is not maintained anymore
and while there is a new iPojo Eclipse plugin maintained elsewhere, I
wouldn't advise using it. Rather, you should use the manipulator from
ant or maven depending on how you build your project. If you choose
the maven-ipojo-plugin, you can get decent Eclipse integration using
Maven's Eclipse environment (M2E).

HTH,

Simon

Re: Getting Started with iPOJO

Posted by "Cook, Michael J. (OCTO)" <Mi...@cable.comcast.com>.

Hmmm...  

Here's my metadata.xml...

I get the following error:

 [ERROR] IPOJO-Extender : Cannot instantiate an abstract factory from

Here's what I had for the Bogus Class case on the metadata.xml:

<ipojo>
<component className="cook.michael.BogusClass"/>
</ipojo>

Re: Getting Started with iPOJO

Posted by Göktürk Gezer <go...@gmail.com>.

Just to be on the same page I installed eclipse-ipojo-plugin too.

First finding : you don't need a bogus component. You can just type
<ipojo>
<component/>
</ipojo>

inside you metadata.xml and it'll pass silently.

Besides you might be hitting a bug we've fixed in trunk, because in the
same scenario I suggested to you I saw some elements in MANIFEST which
shouldn't be there.
Could you share me your MANIFEST for the final state(bogus metadata.xml +
annotations)?

Re: Getting Started with iPOJO

Posted by "Cook, Michael J. (OCTO)" <Mi...@cable.comcast.com>.

Hi,

>>Could you tell me what happens when you remove the <ipojo/> element too
>>leaving the metadata.xml empty?


I get an error when there is no contents in the metadata.xml file.

>>so that eclipse-ipojo-plugin will not fail on metadata.xml and move along

I added a bogus class into the cook.michael package and put the
@Component/@Instantiate/@Validate/@Invalidate back into the code. Then
added this component to the metadata.xml file:
<ipojo>
<component className="cook.michael.BogusClass"/>
</ipojo>



The above results in the start and stop not being invoked.

>>Instead of embedding Felix into eclipse you can use its own Equinox
>>launcher.

I'm developing atop Felix, because the target device is Felix based, so I
would like to keep it on the same platform.
  

Thank you for your help.
Mike

Well, I actually never used eclipse-ipojo-plugin before but it seems to be
dependent on metadata.xml but also sees the annotations on its way.

Could you tell me what happens when you remove the <ipojo/> element too
leaving the metadata.xml empty?

If above trick didn't work and you want to stick with eclipse-ipojo-plugin
while using annotations. I could suggest you a trick to define a bogus
component inside metadata.xml(Will require you to maintain a bogus class)
so that eclipse-ipojo-plugin will not fail on metadata.xml and move along
its way with annotations.

Also it seems to me that your development environment is heavy. Instead of
embedding Felix into eclipse you can use its own Equinox launcher.
I suggest you to have a look at
http://felix.apache.org/site/apache-felix-ipojo-eclipse-integration.html where
you can see basic setup.(You can use annotations or metadata of your choice
in this setup)

Re: Getting Started with iPOJO

Posted by "Cook, Michael J. (OCTO)" <Mi...@cable.comcast.com>.

Göktürk,

Thank you! I used #2 below and it worked well.  I was able to launch the
bundle, and I saw it output the traces I had been looking for.

On the first, if I remove the contents of the metadata.xml file, how can I
use iPOJO to generate the bundle?  If I leave in the <ipojo/> element, and
I run iPOJO's "Create Bundle", I get a warning: "Neither component types,
nor instances in /Users/mcook008/Workspaces/MyEclipse
8.6/iPojoTest/metadata.xml". Start and stop are not called, although the
class is marked with @Component and @Instantiate and start/stop is marked
with @Validate/@Invalidate.

Mike

Re: Getting Started with iPOJO

Posted by Göktürk Gezer <go...@gmail.com>.

Well i thought at first that you didn't specify metadata.xml but i see now
that you did. Mixing metadata.xml and annotations for one single component
is a mistake. For same component you must go with one of them.

So there are 2 different ways for you:

1- Using only annotations: Just disable the metadata.xml (easily delete it
or comment out the content ) and leave the annotations as it is.
2- Using only medata.xml: If you want to use metadata.xml then remove all
annotations including @validate and @invalidate and make sure your
metadata.xml looks like this:

<ipojo>
<component className="cook.michael.MyComponentImpl">
    <callback transition="validate" method="start"/>
    <callback transition="invalidate" method="stop"/>
</component>
<instance component="cook.michael.MyComponentImpl"/>
</ipojo>

Either way should bring you where you want. Just don't mix annotation and
metadata usage for same component.

Regards,
Gokturk

Re: Getting Started with iPOJO

Posted by "Cook, Michael J. (OCTO)" <Mi...@cable.comcast.com>.

Hi Göktürk,

OK... Tried that.  Still the same thing.  There's not much to my code, so
I'm including it below.  Please let me know if you see anything.

Thank you for helping me,

Re: Getting Started with iPOJO

Posted by Göktürk Gezer <go...@gmail.com>.

Hi,

First of all @Component is mandatory.(For annotation based usage).

But this only defines your component. To actually instantiate it you should
do it deliberately. One way to do that is using @Instantiate annotation.

So your code would be like:

@Component
@Instantiate
public class foo{

  @Validate
  public void start()
..........
..........
}

Re: Getting Started with iPOJO

Posted by "Cook, Michael J. (OCTO)" <Mi...@cable.comcast.com>.

Sorry. Just rechecked. Used @ Component on the class. And @Invalidate/@validate on the methods. Just tried removing the @Component. Same result. No output.

Hi,

I need to ask this first since it's not on your code snippet: Did you use
@Component annotation for class where you've declared your start() stop()
methods? Or did you use @Validate,@Invalidate alone?
