You can start with something simple. Have you look through our web tooling?
There is plenty of work to do on that front, and I can introduce you to
those tools.
Look to the web app provided with the jbpm installer to get familiar with.
Get in touch with us when you know the basic of those tools (from the end
user perspective). In order to collaborate with an open source project,
first you need to be familiar with how to use it, so try it out and let us
know how it goes.

Your next step would be to start using the latest version the jbpm 6
console (also called Kie Workbench), download the latest installer, and try
to model a business process and run it in there. You can write a blog post
about your experience with a tool, because that's a good way to start
learning and reinforce what you are doing with the tool.

This is a developer list, please use the user forums.
And try to elaborate more on the question instead of asking for generic
tutorials. Describe what's your problem, are you suck.

Hi Experts,

I'm a student, and I'm currently preparing for my end of study project.
My project is to propose a new conception by modifying the code source of
jBPM.
I'm feeling losed because I couldn't find an idee .
But, before desperation, I'm asking for your help while you present the
leader of jBPM on the world !!!.
I have a knowledge about jBPM-6.0.1 .

Could you please help me by giving me a proposition or a small idea ?!!.

Thank you for any solution.

Hi Liliya,
we can help you out with some ideas, but do you have at least an area of
interest?
I'm currently guiding a couple of students that are contributing with the
jbpm project,
but they usually came with an idea for an improvement.
I would recommend you first get some experience on the project, and that
will give you toons of ideas for improvements.
Usually I recommend building the jbpm console ng repository and play around
with that.

Regards

Subject: [jbpm-dev] services registered by OSGi bundle activators of Kie,
 Drools and Jbpm are still needed ?
Message-ID: <53EE2101.6050109@gmail.com>

Hi,

has a long time that I don't play with Drools and JBPM source code. This 
week I was walking through them again and saw a lot of new elements, 
interfaces and new ways to setup things.

I saw that some Blueprint specific annotations and classes were created 
(kie-aries-blueprint).
But the existent osgi activators are still registering some services 
that seems not be appropriated anymore. at least they are different from 
the set of elements in blueprint namespace (environment, kmodule, kbase 
and others ) that I saw.

For example, in activator of drools-core we have a 
KnowledgeBaseFactoryServiceImpl being registered. in drools-compiler we 
have KnowledgeBuilderFactoryServiceImpl being registered.

I can't use blueprint, so I need to figure out what is the best setup 
workflow for OSGi and get the proper services registered.

Question, is the kie-aries-blueprint.xsd reflecting the actual state of 
kie, drools and jbpm core setup workflow, so I can use it as start point?

could someone check that and give me a feedback ?

many thanks,

Cristiano

I agree that should have a consistency.

but where should we start from ?

are you able to point me to any resource describing a good setup 
workflow using that new stuffs that I can use as base for my own 
investigation?

The examples that I saw until now are using factories. what I can 
remember last time I tried 6.x, that factories won't work in osgi, so 
they are good candidates to be registered by those activators.

It is true that using factories isn't always trivial in OSGi, so the 
activators you are referring to are used (internally) to do additional 
registration for OSGi.  They should be working and are required when 
using OSGi.

On top of this, some additional "sugar" was created that allows you to 
more easily define various elements (kbase, env, etc.) so they can be 
injected more easily.  You are free to use these, but this is not 
required, you could initialize these elements yourself using pure Java 
as well for example.  Afaik, kie-aries-blueprint.xsd should be up-to-date.

There are some osgi examples available here:

Kris and Mark,

I passed this morning analyzing the activators... I'm attaching a sheet 
where I added all Activators being used by Kie, JBPM and Drools. Note 
that where I marked with red I saw "signs of smell things" and added a 
comment...

below I write the reasons I think that we should to remove completely 
those activators...

well, in reality static factory is not recommended at all in osgi. just 
because normally it is implemented adding a strong "dependency" between 
API and one Implementation. and that is against modularity that OSGi 
preaches. In those scenarios in order to change an implementation almost 
all the times you will need to change the api also.

I saw the addition of ServiceRegistryImpl to concentrate the services 
without a DI. that  would reduced a bit this problem (btw, I saw some 
factories where it isn't being used yet: org.kie.api.KieServices) but 
not all... to me the best solution for non-osgi to separate API from 
Implementor still is JavaSE Service Locator.

Maybe those activators used to be required and useful (internally) some 
day. But currently, I don't think they are needed anymore.

The reasons I think they should be removed:

First, there many services being registered using interfaces from 
non-API packages;

Second, the focus of RedHat seems to be Fusion/ Karaf and they already 
use blueprint natively.

Third, there are a project exclusive for blueprint based setup, so 
doesn't make any sense to me to use ServiceTracker and register things 
"by hand in activator" and then complement that using blueprint. Why not 
just use blueprint  ??

Fourth, we can't use one of the most useful features of OSGi, the 
Configuration Admin service. So, we can't (re)configure the registered 
services at runtime using simple service properties...

Fifth, those activators don't scale ! if I have an environment 
(multi-tenant) where I need to have more than one version running same 
time.

So, would help much more if those activators were removed, and improve 
the blueprint project to register all that is needed for it. after that 
we could create other projects for people wanting to use OSGi 
Declarative Services and maybe a OSGi CDI just like the Blueprint one....

And I bet we could figure out a much more clever way to synchronize the 
"internal registry" with the OSGi service registry instead have to call 
ServiceRegistryImpl.getInstance().registerLocator inside the activator 
(Drools-Compiler). One possibility is to create an OSGi implementation 
for ServiceRegistry interface instead use ServiceRegistryImpl in all places.

Hi,

Before to review the code, it could be interesting to define/describe in a
document the services/factories that we need to work with Drools/BPMN,
dependencies between the modules/jar (= Packages to be exported/imported)
and next we could see how we could improve the design of what has been done
for OSGI. Aries Blueprint could be used or Apache DS to inject dependency
(less code and dependencies are needed vs Blueprint) but Weld/CDI is also
another option since that pax-cdi has been released but I should have a
look to verify stability, ...

Regards,

Charles
