Drools OSGi Bundle

[Remi Barraquand]

Hi there,

I'm a newby with Felix, OSGi and all the stuff... and i try to create a Bundle for the Drools library.
You can find the binary version of Drools over here : http://www.jboss.org/drools/downloads.html

Drools library is divided as follow:

drools:
drools-jsr94-4.0.7.jar
drools-analytics-4.0.7.jar
drools-ant-4.0.7.jar
drools-compiler-4.0.7.jar
drools-core-4.0.7.jar
drools-decisiontables-4.0.7.jar

drools-dependency
lib>ant-1.6.5.jar
lib>janino-2.5.10.jar
lib>xercesImpl-2.4.0.jar
lib>antlr-runtime-3.0.jar
lib>jsr94-1.1.jar
lib>xml-apis-1.0.b2.jar
lib>ant-nodeps-1.6.5.jar
lib>jxl-2.4.2.jar
lib>xpp3_min-1.1.3.4.O.jar
lib>core-3.2.3.v_686_R32x.jar
lib>mvel-1.3.1-java1.4.jar
lib>xstream-1.2.2.jar

On the drools download page you can find as well the maven repository with the pom file to build the Drools Library using maven. I partially used this pom to create a bundle of this library.

I have however a lot of difficulty... i managed to create the bundle, but when i start it using the obr start command, Felix shout me some error saying that there is missing dependency....

..........

Those dependency should be dependency needed by the jar library drools is using in the lib/ folder of Drools.... However when i'm using Drools as a normal library i don't have any problem of any kind !!

Is the problem coming from making the bundle ? are is the problem coming from Felix classloading ?
I don't know really where to look... but i think i need to tell either Maven or Felix to not load dependency of dependency.... how to do that ?

Could someone help ?

thanks,

[peterd]

Hi,

I guess you created this drools bundle with Bnd. Bnd analysis the code  
and concludes that classes from these packages _could_ be needed and  
that's why it generates imports for it. If you are sure that these  
packages are not needed at runtime, you can tell bnd to exclude them  
from the import list. That leaves the risk that things go wrong at  
runtime of course, that is what bnd and felix try to protect you from.  
The best thing to do would be a thorough analysis of why these classes  
are found by static analysis if they aren't used at runtime. I've seen  
similar issues, where devevelopment tools and runtime environment were  
bundled in one jar.

Hth,
Peter.

Hi Remi,
In the JASMINe project we provide a bundle of Drools that allows to add and remove dynamically some rules embedded  into some other bundles. To see how we have resolved your problem, I propose you see here: http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/jasmine/jasmine/trunk/jasmine-control/DroolsResourceAdapter/

Best regards,
Loris

Thanks for your reply,

Actually i'm using the maven-bundle-plugin as well as the maven-ipojo-felix plugin to create the bundle. The maven-bundle-plugin is using the Bnd if I remember well...

I've no idea how to do it :)

[Remi Barraquand]

Hi Loris,

Ali told me about your Jasmine Drools port, I've just looked it back again and i found your jasmine-drools-api.bnd ;) this will maybe save my life :)

Ok i'll try it, i let you know ;)

Hi,

I'm a newbie with Felix. I just want to find out how to run Felix in
background with my default profile.

Something like this: *java -jar bin/felix.jar &

*Is there a way?

Thank you guys all.

brs,
Honnix

I guess you are concerned about Felix prompting you about the profile
name. If you set felix.cache.profile or felix.cache.profiledir property
in config.property file, then Felix won't prompt you anything and the
command you mentioned would be sufficient.

Thanks,
Sahoo

Thank you very much. I did as you said, but when I try to launch Felix
using java -jar bin/felix.jar &, it will be suspended in the background,
since it tries to get the input. See output below:

shadow@shadow:~/Downloads/development/apache/felix-1.0.4 $ java -jar
bin/felix.jar &

Then what if I don't want this terminal to be blocked, and only put
Felix to the background? Is this possible? I can do this with Equinox by
not giving -console argument.

Yes, you can do something similar using Felix. Just disable the
org.apache.felix.shell.tui bundle in conf/config.properties. That's the
one which is waiting for console I/O. Look for
org.apache.felix.shell.tui*.jar in config.properties and remove that
bundle from the autostart list.

Thanks,
Sahoo

Thanks very much for your kindly help. I removed tui from
conf/config.properties, and restarted Felix, tui was still running
there, then I stopped it manually, and restarted Felix, and it was done.
Now I can put it to background successfully. ;-)

Thank you again.

Hi again,

I managed to create my Drools Bundle by using a specific .bnd file like you said Loris, the bundle can be started and used to create a session. However i cannot compile any mvel package !!

my drools-bundle.bnd looks like the following:

*******************************************************************

*******************************************************************

When i open the generated jar bundle, i find all the needed jar dependency.

I created a simple bundle project "PackageLoader" that uses this drools-bundle and creates a drools session, tries to create a PackageBuilder and add a drl file. Then inserts a simple fact and call fireAllRules on the session.

But when i try to create my PackageBuilder, i get the following exception:

org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.mvel.MVELDialectConfiguration:mvel'

This exception look like Felix don't find the mvel-1.3.1-java1.4.jar, but this jar is in the drools-bundle.jar !!

Does someone have any idea what the hell the error could come from ?

thanks a lot for any help ;)

Is this the recommended way of running Felix as a daemon? Summary:

* Disable shell.tui (by removing the autoload paramater)
* Set felix profile (-Dfelix.cache.profile=<some-profile>)
* Redirect stdout and stderr to some log file ( >> felix.out 2>&1 )

e.g:
  (cd ~/felix-trunk/main; java -Dfelix.cache.profile=myProfile -jar bin/felix.jar) >> /var/log/felix.log 2>&1 &

Is there an init-script that does this (possibly in a cleaner way...)?

No, I think that is it. Now you might think about including shell.remote
so you can remotely access the Felix shell (or the web console).

Felix itself doesn't make any attempt to use stdin, but the simple
launcher does (i.e., it assumes it can ask for a profile if one doesn't
exist and is configured to autoload the shell.tui), but it is
configurable to avoid doing these things.

How would you like it to be cleaner? Do you mean having it set up as a
daemon automatically?

We have some work started on an installer that will automatically
install Felix as a daemon, but unfortunately that has stalled.

Sure.

«the simple laucher does...»? Is felix normally run from another
application (like I guess it is when running Eclipse)? I would like to
run Felix on a server to be a backend for business logic. And then I
only want to start the Felix server.

Most programs designed to run as a daemon will ensure that stdout and
stderr are redirected to syslog (or a logfile) and stdout are closed
before forking a process to run in the background. And possibly a debug
mode where the console are kept as output. Thats what I was expecting,
but didn't find.

Yeah, I read about something in the archive from November 07 about using
Java wrapper. I tried it out and it seems to work on our Linux server.
