Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Jörg Richter]

Mmh, not really an idea so far.
The steps you describe look OK.

Try to build and install the Neo4j bundle alone:
cd neo4j-osgi/bundle
mvn clean install

Then try out this project:
https://github.com/jri/neo4j-osgi-test
It provisions a standalone Felix runtime (with the aid of Pax Runner).

There I also describe the steps that worked for me (seemingly the same as you 
tried :-|

Cheers,
Jörg

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Jean-Pierre Bergamin]

BTW: When I try to install the bundle
org.neo4j.examples.osgi:test-bundle on virgo I also get the lucene
error, although I have deployed the patched neo4j 1.5-SNAPSHOT bundles
to the repository/usr of Virgo.

It seems as if the test-bundle has the correct manifest and I can
verify that Virgo provides the imported packages, e.g. with "clhas
org.neo4j.graphdb.index.IndexProvider".

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Jean-Pierre Bergamin]

Helly everyone

I'm currently also stuck with the "No index provider 'lucene' found"
error that you all seem to have been able to work around.
I have built and installed the 1.5-SNAPSHOT kernel from the
bundle-friendly-classloader branch and installed it locally (mvn
install).
When I run the neo4j-osgi tests I still get the mentioned lucene error:

...
[FelixDispatchQueue] DEBUG org.neo4j.examples.osgi.test-bundle -
BundleEvent STOPPED
ERROR: Bundle org.neo4j.examples.osgi.test-bundle [3] Error starting
file:bundles/org.neo4j.examples.osgi.test-bundle_0.1.0.SNAPSHOT.jar
(org.osgi.framework.BundleException: Activator start error in bundle
org.neo4j.examples.osgi.test-bundle [3].)
java.lang.IllegalArgumentException: No index provider 'lucene' found
at 
org.neo4j.kernel.IndexManagerImpl.getIndexProvider(IndexManagerImpl.java:76)
...

Failed tests:
  neo4jStartupTest(org.neo4j.examples.osgi.OSGiTest)
  bundleStartupTest(org.neo4j.examples.osgi.OSGiTest)

Is there anything else I have to to so that I get the examples up and running?

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Jörg Richter]

Hi Peter,

SUCCESS!!!

"No index provider 'lucene' found" in OSGi is solved for the moment!

Its exactly as you suggest:
When using pax exam's native container no error shows up.
When using pax exam's pax runner container the error shows up (which is correct 
OSGi behavoir).
When using bundle-friendly-classloader branch of neo 1.5-SNAPSHOT kernel the 
error disappears!
My neo4j-osgi-test project runs successful now!

I'm looking forward to have a patch like yours in the next neo4j stable.

Thank you and Toni very much for investigation.

Cheers,
Jörg

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Peter Neubauer]

Jörg,
there where several issues Toni and me found when looking at your
example. Thanks a lot!

First of all, Pax Exam Player using the built-in native OSGi Runner is
not emulating the real platform classloading correctly. Toni is at
this one, the tests are switched to the PaxRunner instead, running in
its own process.

Secondly, the Neo4j Service.java that is loading the classes and
resources is not providing a classloader, which in an OSGi bundle
defaults to a classloader that does not find the interesting classes
and services. With

private static  Iterable java6Loader( Class type )
{
try
{
@SuppressWarnings( "unchecked" ) Iterable result = (Iterable)
Class.forName( "java.util.ServiceLoader" )
.getMethod( "load", Class.class, ClassLoader.class )
.invoke( null, type, Service.class.getClassLoader() );
return filterExceptions( result );
}
catch ( Exception e )
{
return null;
}
catch ( LinkageError e )
{
return null;
}
}

Everything works, but we need to discuss more what classloader to
chose in what contexts, as this might not be great in all
circumstances.

Anyway, you can build the fixed kernel project from
https://github.com/neo4j/community/tree/bundle-friendly-classloader,
then build the https://github.com/neo4j/neo4j-osgi and you should be
able to start up your test project (see my pull request).

Let me know if that works!

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Jörg Richter]

Meanwhile I tried a 3rd test scenario: Activator and all neo packages in one 
bundle again, but in a proper one (additional inlining of embedded jars 
suppressed). Same error: "No index provider 'lucene' found".

To run the various test scenarios checkout the respective tag, as described:
https://github.com/jri/neo4j-osgi-test

Apparently there is a crucial difference in classloading (or something) when 
running in Pax Exam and when running independantly.

Cheers,
Jörg

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Jörg Richter]

Peter,

no problem, take your time.

I see your super bundle test running OK in pax exam, but with an independant 
deployment scenario "No index provider 'lucene' found" is a persisting error.

Meanwhile I tried the approach you suggested: having the neo-super-bundle and 
my activator as separate bundles. No success.

And even with your "official" super-bundle (neo4j/neo4j-osgi/bundle): same 
error.

To demonstrate the problem I refactored the test project to utilize your 
super-bundle:
https://github.com/jri/neo4j-osgi-test

To run it:
git clone git://github.com/neo4j/neo4j-osgi.git
cd neo4j-osgi
mvn clean install
cd ..
git clone git://github.com/jri/neo4j-osgi-test.git
cd neo4j-osgi-test
mvn clean install pax:run

The test is very small. Just your super-bundle as dependency:


org.neo4j
neo4j-osgi-bundle
0.1-SNAPSHOT
provided


And my activator (in package de.deepamehta.neo4j):

public void start(BundleContext context) {
GraphDatabaseService neo4j = new 
EmbeddedGraphDatabase("test-db");
Index index = neo4j.index().forNodes("exact");
}

Along with straight-forward bundling instructions for the activator:



de.deepamehta.neo4j

de.deepamehta.neo4j.Activator




I'm eager for knowledge.

Have a nice travel :)

Cheers,
Jörg

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Peter Neubauer]

Jörg,
I can see your problem in the project. It seems the bundle is inlining
all the classes, AND adding the dependencies as JARs.

I have no time to investigate further because of travel for the next
day, but it might be that the Activator being in the bundle with the
libraries is messing up the build. Could you try the other approach
like in neo4j-osgi - having a library bundle, and your activator in a
separate one?

Sure.

Just one addition for tomorrow: the only neo-bundles my application need are 
kernel and lucene-index. So I did add just these 2 to the super bundle's 
dependencies instead the neo4j meta package.

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Jörg Richter]

I'm seriously trying the superbundle approach and can't get rid of "No index 
provider 'lucene' found".

The tests at https://github.com/neo4j/neo4j-osgi run successful but I have 
serious problems to transfer them to my application (I'm using Felix 3.2.1 on a 
Mac).

Just to check my understanding: the "No index provider 'lucene' found" problem 
is with fine granular bundling, OSGi classloaders, and Java's service loader. 
One way to solve it is the superbundle approach: putting the user application's 
activator and all required neo and lucene bundles/libs into a single bundle. 
Correct?

So I took neo4j-osgi/bundle/pom.xml as an template for my application's pom, 
especially its bundle plugin configuration:


!javax.transaction.*,!com.sun.*,!sun.misc.*,!org.junit.*,!junit.*,*;
org.neo4j.*;version="1.4",*
*;scope=compile|runtime
true

and added my application's activator:

 de.deepamehta.neo4j.Activator 

The activator's start() method is fairly simple:

public void start(BundleContext context) {
GraphDatabaseService neo4j = new 
EmbeddedGraphDatabase("test-db");
Index index = neo4j.index().forNodes("exact");
}

But it throws: java.lang.IllegalArgumentException: No index provider 'lucene' 
found

The bundle list looks fine (#1 is the super bundle):

ID|State  |Level|Name
 0|Active |0|System Bundle (3.2.1)
 1|Resolved   |5|Neo4j OSGi Test (0.1.0)
 2|Active |1|Apache Felix Gogo Command (0.8.0)
 3|Active |1|Apache Felix Gogo Runtime (0.8.0)
 4|Active |1|Apache Felix Gogo Shell (0.8.0)

To let you reproduce this I packed a minimal test project here:
https://github.com/jri/neo4j-osgi-test

Run it:
git clone git://github.com/jri/neo4j-osgi-test.git
cd neo4j-osgi-test
mvn clean install pax:run

This uses pax runner to provision the super bundle in a Felix runtime.
Deploying the super bundle manually in Felix makes no difference.

Using the latest Maven bundle plugin (2.3.5 instead of 1.4) makes no difference 
(after tweaking the pom a little) and also getting rid of the bundle plugin's 
warnings (again by tweaking the pom) makes no difference.

Who can help?

Jörg

So,
now, with another merge from Toni, you should be able to build
https://github.com/neo4j/neo4j-osgi with just

mvn clean install

Enjoy!

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Toni Menzel]

btw, sorry about the Tinybundles disruption. The group id "org.ops4j.pax"
was actually wrong since ripping out tinybundles from pax swissbox.
Actually there will be just one tinybundles artifact and it will carry 1.0
really soon.

Until then you may grab latest artifacts from
https://oss.sonatype.org/content/groups/ops4j/ .

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Peter Neubauer]

And, there was a bug in Pax Exam not shutting down the bundles
properly. Fixed by Toni Menzel in 5 minutes. Thanks!

I added some build instructions to https://github.com/neo4j/neo4j-osgi
to get things working. Give it a try!

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Jean-Pierre Bergamin]

Hi Peter

When I ran mvn install, I got:
...
[WARNING] Warning building bundle
org.ops4j.pax.tinybundles:tinybundles:bundle:1.0.0-SNAPSHOT
...
[INFO] Installing
org/ops4j/pax/tinybundles/tinybundles/1.0.0-SNAPSHOT/tinybundles-1.0.0-SNAPSHOT.jar

I think there is a "tinybundles" to much in between. :-)

I moved the 1.0.0-SNAPSHOT folder one level up in the .m2/repository
folder structue and at least the tinybundles jar can now be found in
the neo4j-osgi projects.

I now have compilation errors in the examples project:
[ERROR] Failed to execute goal

And indeed, the org.ops4j.pax.tinybundles.core.builders package is not

Hi Jean-Pierre,
sorry for the inconvenience, the Tinybundles version is not yet
released by the OPS4J team, so you can build it yourself from

https://github.com/ops4j/org.ops4j.pax.tinybundles

with

mvn clean install

Feedback is appreciated!

 Hi Peter,

 I've comited a new test case which work with a pre-built bundle.
 It currently fails because in OSGiTest class the first test case doesn't
 close the database, but if you remove the @Test before the first test case
 the second one will run and succeed.
 So the neo4j superbundle seems to work correctly, event if I don't know
 what's wrong when doing it by hand on the felix framework. This need more
 time to investigate.
 Don't hesitate to pull code if needed.

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Jean-Pierre Bergamin]

Hello everyone

May I chime in here...

We are really interested to see neo4j working in an OSGi environment
esp. together with Spring Data Graph. After an unsuccessful attempt to
get it up and running a couple of weeks ago we gave it another chance
today after seeing this post and after a whole day of debugging and
fiddling around with manifests and template.mf and osgi.bnd we have  -
hurray - a running neo4j and Spring Data Graph setup in Virgo (based
on Equinox).

Regarding the error with the missing lucene index Provider
(java.lang.IllegalArgumentException: No index provider 'lucene' found)
I also would like to refer to this "discussion" here:
https://github.com/neo4j/community/commit/e8574e96315999ab04e1b484717bb2b1a3dfa9be#commitcomment-483325
I also had the "No index provider 'lucene' found" error with neo4j
1.4. With 1.3, the workaround was to export the org.neo4j.index.impl
package, which is not working with 1.4. Instead I just registered an
instance of LuceneIndexProvider from the lucene-index bundle as a osgi
service. After doing this, this index provider can be found as an OSGi
service by the kernel.
We currently register this service within our application, which is
probaby not the right solution. I think the lucene-index bundle should
export the LuceneIndexProvider service itself, shouldn't it?

I also tried to get your example up and running, but I have a missing
dependency: "Failure to find
org.ops4j.pax:tinybundles:jar:1.0.0-SNAPSHOT". Which snapshot
repository does contain the tinybundles jar?


Best regards,
James

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Nicolas Jouanin]

Hi Peter,

I've comited a new test case which work with a pre-built bundle.
It currently fails because in OSGiTest class the first test case doesn't close 
the database, but if you remove the @Test before the first test case the second 
one will run and succeed. 
So the neo4j superbundle seems to work correctly, event if I don't know what's 
wrong when doing it by hand on the felix framework. This need more time to 
investigate.
Don't hesitate to pull code if needed.

Nicolas

 I've forked you repository and tried to make is work using this sample

Nicolas,
the best would be to be able to emulate this in a test, too. Maybe
classloading issues? Maybe forking the PaxExam test will reproduce the
issue, or running you Felix setup as a testcase to trigger this?

The OSGiTest is working fine for me too. Problems come when taking the felix

I made sure to deploy same bundles but I get

Hi Nicolas,
Have you been able to run
https://github.com/njouanin/neo4j-osgi/blob/master/examples/src/test/java/org/neo4j/examples/osgi/OSGiTest.java
properly? It actually is running on Equinox, so let me try it with
Felix ... back in a moment.

Also, in order to pull your changes, could you sign up as a committer,
and send a mail according to
http://wiki.neo4j.org/content/About_Contributor_License_Agreement ?


Cheers,

Re: [Neo4j] OSGi and Neo4j - superbundle approach

[Nicolas Jouanin]

Hi Peter,

Thanks for initiating this work on OSGi bundle.
I've forked you repository and tried to make is work using this sample 
activator [1]. My goal is to make my activator work when deployed on Felix with 
the neo4j superbundle.
First of all, I had troubles to mvn clean install the bundle module. 
maven-bundle-plugin is complaining about bundle.namespace property not set. 
I've fixed it.
Then when deploying it on Felix I had an error saying that javax.transaction 
couldn't be imported. Because this package is already included in superbundle, 
I've removed it explicitally from the Import-Package directive. You can see the 
changes here [2].
Then I tried to make my bundle activated using felix and the following bundles 
installed :
g! lb
START LEVEL 1
   ID|State  |Level|Name
0|Active |0|System Bundle (3.2.2)
1|Active |1|Neo4j OSGi default bundle (0.1.0.SNAPSHOT)
2|Active |1|Apache Felix Bundle Repository (1.6.2)
3|Active |1|Apache Felix Gogo Command (0.8.0)
4|Active |1|Apache Felix Gogo Runtime (0.8.0)
5|Active |1|Apache Felix Gogo Shell (0.8.0)
6|Resolved   |1|EscapeK - Neo4j OSGi how-to - Embedded client 
(0.0.1.SNAPSHOT)
There are only felix core, neo4j superbundle and my test bundle.
So when starting felix I get the following trace : 

Welcome to Apache Felix Gogo

g! Opening database in embedded mode: 17 juil. 2011 14:57:08 
org.neo4j.kernel.impl.transaction.xaframework.XaLogicalLog doInternalRecovery

OK
Populating it ... OK

at 
org.apache.felix.framework.StartLevelImpl.run(StartLevelImpl.java:266)
at java.lang.Thread.run(Thread.java:680)

So everything works fine (open database, populate it and register service) 
until the activator tries to register IndexProvider service. I then get the 
previous exception which reminds me of something ...

May be you can have a look at the stack trace to look for the error cause.

[Neo4j] OSGi and Neo4j - superbundle approach

[Peter Neubauer]

Hi all,
I just pushed an initial working bundle-build to
https://github.com/neo4j/neo4j-osgi. You can see the working test in
https://github.com/neo4j/neo4j-osgi/blob/master/examples/src/test/java/org/neo4j/examples/osgi/OSGiTest.java
that waits for the Activator to instantiate and register a
GraphDatabaseService and a LuceneIndex.

This should be tweaked, but maybe you can use the bundle project
https://github.com/neo4j/neo4j-osgi/blob/master/bundle/pom.xml , which
is just one pom.xml, as a blueprint for your OSGi environment Neo4j
bundle.

Right now JTA and others are drawn into the bundle, which might be too
much, but I think you get the picture.

This works even with the Java Service Loader architecture. Feel free
to fork and tune the bundles exports, and add more tests to it.

WDYT?

Cheers,
