Re: SCA and BPEL

[Matthieu Riou]

Hi Sam,

I've had a look at your implementation and played with a couple of things on
my side as well. I think I have a much better idea of how things can play
with each other now and how to solve your problems.

- For server instantiation, you should create a separate component for it
with @Init and @Destroy annotations. I've made a rough implementation of it
and I think you could take it and start from that. You'll just have to add
the component as a system implementation in your bpel.system.cdl. I'll
attach the java file to the same Jira issue. Then you can have this injected
in the  BpelComponentBuilder using a constructor like:

   public BpelComponentBuilder(@Autowire BpelServerLoader serverLoader) {
   _server = serverLoader.getServer();
   _store = serverLoader.getStore();
   }

That should fix the server instantiation problem.

- For the binding part you will need to go through a real remote web service
invocation. Check of the Tuscany helloworldws is structured with the
sample-helloworldws web application being deployed in Tomcat and the client
sample-helloworldwsclient calling it remotely. I think you can even reuse
the client almost as is. However the server side should change to something
like:

   
   http://ode/bpel/unit-test.wsdl#wsdl.interface(HelloPortType)"
   wsdli:wsdlLocation="http://ode/bpel/unit-test.wsdl
HelloWorld2.wsdl"/>
   http://ode/bpel/unit-test.wsdl#wsdl.endpoint(HelloService/HelloPort)"
location="HelloWorld2.wsdl" />
   HelloWorldBPELComponent
   

   
   
http://ode/bpel/unit-test.wsdlHelloService"/>
   

Again check the Tuscany sample-helloworldws service declaration, it's almost
the same except for the implementation that will be BPEL in our case instead
of java. You can even use the same type of SDO databinding So you will need
to package the BPEL container on the server side in Tomcat and that should
get loaded.

Let me know if you need more,

Hello Guys..

As discussed earlier about Integration of SCA(Apache Tuscany) and BPEL
(Apache Ode),

I have started with a bpel container for Apache Tuscany(SCA).

Also i have attached a small readme file .

And a test case file also.

The link for the attached source is :
http://issues.apache.org/jira/browse/TUSCANY-897?page=all

Comments:

Things to do :
- need to figure out a better way than instantiating the server for every
component
- need to bring in databinding into the invoke method to be able to
convert
java objects to xml that can be sent over ODE requests and also do the
reverse for the response.


Guys I need your feedback on this !!! Plz share your ideas . !!.

Re: IRC chat on Ode/Tuscany integration: Thursday 2nd Nov 4pm GMT/8amPST (was Re: SCA and BPEL)

[victor panizza]

Hello All.
Just a little question.

I been working with WebSphere Process Server, in the top WPS provides SCA
Components like:
 Business Rules.
 Selectors.
 Human Task.
 BPEL Process.
 States Machines (Implemented using BPEL).

Which of those components actually are supported in tuscany??

Re: IRC chat on Ode/Tuscany integration: Thursday 2nd Nov 4pm GMT/8amPST (was Re: SCA and BPEL)

[Matthieu Riou]

For those who couldn't attend, here is the transcript of the chat session:

[08:00]  so shall we start on the BPEL / SCA topic a.k.a. ODE /
Tuscany ?
[08:00]  yes..ofcourse...
[08:01]  Alex is here as well, Lance tried to join us but he has
a firewall problem
[08:01]  can't connect to IRC
[08:01]  hi all
[08:01]  hi ant
[08:01]  how are you doing?
[08:02]  Hi guys!
[08:02]  doing fine...so Tuscany and Ode
[08:02]  have you all had a look at the white paper and spec on the
osoa website?
[08:02] --> lmsurprenant has joined this channel ([EMAIL PROTECTED]
/ibm/x-36f69103afa7a9f8).
[08:03]  I'd like to know if anybody here has experience
integrating "engines" into Tuscany
[08:03]  It would be good to have a model to follow
[08:03]  I've had a look at the spec, not the white paper
[08:03]  yes..i did look at the white paper ..Ant
[08:03]  and SCA C & I model
[08:04]  we have a few Tuscany containers now, which is whats reqd from
tuscany perspective, you can see the code at
https://svn.apache.org/repos/asf/incubator/tuscany/java/sca/services/containers/
[08:05]  all run under java and c++ or some only run on Java and
others on C++ ?
[08:05]  those are only the java ones
[08:06]  ok, nice
[08:06]  the C++ has extensions as well but its quite seperate
[08:06]  the code doesn't seem that big, that's nice
[08:06]  Is there  another  way to contact SCA ie by bindings ? Am i
right Ant ?
[08:07]  what kind of XML representation does Tuscany use
internally?   DOM?
[08:07]  Sam, yes, but the bpel spec talks about using an
impelementtaion type not a binding
[08:07]  oh ok Ant
[08:08] --> Amita has joined this channel ([EMAIL PROTECTED]).
[08:08]  there's a runtime databinding framework which means the
runtime will give the extension data in whatever type it requires
[08:08] <-- lmsurprenant has left this server (Read error: 131 (Connection
reset by peer)).
[08:09]  and which types are currently supported?
[08:09]  the extesnion tells the ri=untime what it requires, and maybe
contrabutes a databinding extension, and then the runtime uses that to
transform the message to whats needed
[08:09]  right now there's sdo, jaxb, cator and axiom:
https://svn.apache.org/repos/asf/incubator/tuscany/java/sca/services/databinding/
[08:10]  i thnk also as part of the runtime DOM and StaAx
[08:10]  what does Ode use internally?
[08:10]  neat!
[08:10]  mostly DOM
[08:11]  we convert Axiom as well for Axis2
[08:11]  and to/from JAXP Sources with JBI
[08:11]  right
[08:11]  I guess the format that would make sense for now would
be DOM
[08:12]  so tuscany should be able to just give the Ode extension DOMs
so it should would quite easily
[08:12]  so how many interfaces you need to implement to build a
container?
[08:15]  ok so a container includes an scdl file defining the classes
it adds to the runtime, for example:
[08:15] 
https://svn.apache.org/repos/asf/incubator/tuscany/java/sca/services/containers/container.javascript/src/main/resources/META-INF/sca/default.scdl
[08:16]  the loader as the class that handles the XML config file
[08:17]  for BPEL the spec defines the XML as:
[08:17]  *
[08:17] 
[08:17]  
[08:17] --> halehM has joined this channel (n=
[EMAIL PROTECTED]).
[08:18]  makes sense
[08:18]  so you need a class that has a type name of
implementation.bpel
[08:18]  and that will pick up the process= attribute
[08:18]  and how would deployment work? for now we use deployment
packages that contain BPEL files, WSDL and XSD files and a deployment
descriptor, so that's not only a BPEL
[08:19]  what is your deployment package? sometheing liek a jar file?
[08:19]  i think they have some war file..(ode.war) ..
[08:20]  it's either a zip or an exploded directory version of it
that you can copy under a "well-known" location
[08:20]  the war is the whole thing
[08:20]  oh ok
[08:20]  but when you deploy a "processes" directory gets created
in ode/WEB-INF
[08:21]  so dropping a directory in processes containing all the
necessary files will trigger hot deployment
[08:21]  but we also support remote deployment using a ws
interface
[08:21]  and then you send a SOAP message using a MTOM attachment
with your zip file in there
[08:21]  but that's for Axis2
[08:22]  I guess the mechanism would be different with scca
[08:22]  sca
[08:22]  that would be with Ode handling the sending and receiveing of
WS messages
[08:23]  yes, with a BPEl container i think Tuscany would need to
handle the sending/receiving
[08:23]  right but the deployment in handled by Tuscany right?
and we would be notified when a complete service bundle is deployed (could
contain bpel, ruby and javascript)
[08:23]  so as in the picture in the white paper:
http://osoa.org/display/Main/SCA+BPEL+White+Paper
[08:24]  right
[08:24]  in the simplest case the service and references would be wired
to WS bindings so the BPEL/Ode process would directly receive/send the WS
messages via tuscany
[08:24]  yep
[08:25]  one thing i wondered about, one of you samples talked about
receiveing back 

IRC chat on Ode/Tuscany integration: Thursday 2nd Nov 4pm GMT/8amPST (was Re: SCA and BPEL)

[ant elder]

As discussed, they will be an IRC chat to aid getting started with an Apache
Ode component for Tuscany.

The chat will take place on the freenode IRC network, (use server
irc.freenode.net), on channel #tuscany at:

4PM GMT, 8AM PST, 9:30PM India
Thursday 2nd November

Everyone is welcome to join in.

Actually most Ode committers (including myself) are in California. Also
we're going to be a bit busy early next week. So would 4pm BST (8am PST) on
Thursday work for you?

Re: SCA and BPEL - Integration

[Matthieu Riou]

Hi,

Nice volunteering indeed!

So on the Ode side, I'd go with implementing a specific integration layer
for Tuscany instead of reusing the Axis2 one. That would allow in-VM SCA /
BPEL interactions and a greater integration between the two.

Ode provides an integration API that you have to implement if you want to
plug the engine into something else. The engine uses this API to get
whatever it needs to work, like the ability to send and receive messages, to
get some representation of the services it's going to interact with, or even
threads and transactions. So you would just wire up all services Tuscany
provides into the engine when implementing these interfaces.

To see what those look like you can have a look at [1]. We currently have 3
working implementations for these interfaces: Axis2, JBI and test. The Axis2
one is wrapped around Axis2 in a WAR and works in any servlet container. The
JBI one is bundled in a Service Assembly and can be deployed in ServiceMix.
The test one works in-memory in a standalone manner. These are great
examples to look at to see how the required services are provided to the
engine and how everything is initialized. In particular you can have a look
at ODEServer [2] for Axis2 and OdeLifeCycle [3] for JBI, these are where all
the initialization and wiring up logic happens for these 2 integrations.

I'd start from the test IAPI implementation [4] [5] to see how things work
out, this will run in memory so you won't have to worry about providing a
datasource and a transaction manager to start with. Then you can bring some
pieces from the Axis2 and JBI integrations (copy / paste is your friend) and
increment from that. Implement the different communication interfaces by
using Tuscany services and you should be all set.

Now I think we could discuss about the details and how to use Tuscany
services in Ode during an IRC chat session as I proposed in the other
thread? So we can all have a better understanding of how this will work and
you'll have more information to start from.

Hi Sam,

Its great you're interested in this, it would be really good to have BPEL
support in Tuscany. In case you didn't see due to all the ASF email
problems
over the last few days, the Ode guys have also just started talking about
this: http://www.mail-archive.com/tuscany-dev@ws.apache.org/msg10042.html.

I talked about how to start a new container in this old mail:

http://mail-archives.apache.org/mod_mbox/ws-tuscany-dev/200610.mbox/browser
.
I'd start with trying to get a simple helloworld going which for this
would
be a combination of the Tuscany helloworldws sample and the Ode
axis2-examples HelloWorld2.

Basically start by copying the existing sample and one of the Tuscany
containers, rename everything to BPEL. Remember when you do the
copy/rename
there's scdl in the META-INF/sca directory that you'll need to edit to
update with the new class names.

As there's an existing SCA spec for this you get some help with what to
do.
The spec defines what the implementation element looks like:

  

So you'll need something like a BPELImplementation and
BPELImplementationLoader for that. Use one of the existing ones and just
change the  QName constant to be "implementation.bpel" and the code to
read
in the attribute named "process". A harder part will be how Tuscany
locates
the BPEL process XML, for now its likely easiest to add a location
attribute
and have the loader just read it in, and then sort this part out properly
later oncee th

Hi Matthieu, this would be really great, i'd love for Tuscany to get a
involved with Ode to get a BPEL component.

For those that haven't found these already there's a white paper on SCA
and BPEL [1] and a specification [2].

You can see the type of thing required to implement a container for a new
component type in Tuscany by looking at some of our existing ones [3]

I agree it may be easiest for the discussions to be over here initially,
but i've subscribed to ode-dev as well anyway. I'd be very happy to help you
do this, how would you like to get started?

later oncee things are working. So that would become:

 

The SCA BPEL spec talks about using introspection to work out the services
and references used by the BPEL process, i'd leave this for later also and
just require a .componentType side file for now. Again, just use some
existing ComponentType and ComponentTypeLoader classes unchanged.

Copy some XxxComponent and XxxComponentBuilder classes and change them to
set up and create the necessary Ode objects, and an XxxInvoker to do the
invoking of the bpel process.

As the Ode people are also interested in doing this maybe you should try to
work together. How about start with small patches which I can get committed
to our sandbox so everyone can see how things progress.

Or would it help if I created a folder and template for this in the sandbox
first for you all to send patches in against? Let me know...

The objective is to see which possible collaboration could happen between

(we're
all Ode contributors) met with Jean-Sebastien Delfino and Simon Laws

From the Tuscany side, there's an SCA client and implementation spec for
BPEL. Roughly, it defines how a BPEL process can be used as an SCA
component
(or at least that's my understanding of it). So I guess Ode could be a
good
choice for the BPEL part of that.

From the Apache Ode perspective, we've defined an interface to the engine
(
a.k.a. the integration API or IAPI for acromyn lovers) and we would like
to
support several integration scenarii. Currently we have an integration
layer
for Axis2 to support all web services interactions, we also have one for
JBI
and another one for CXF has been proposed. We would love to have an
implementation of these interfaces for Tuscany to be able to run Ode in an
SCA environment (for the curious, the interfaces are
here<
https://svn.apache.org/repos/asf/incubator/ode/trunk/bpel-api/src/main/java/org/apache/ode/bpel/iapi/
>
).

I think the discussion (if discussion there is) should take place on
tuscany-dev as there's less of us, Ode people, so it's easier for us to
subscribe to it.

So what would it take to fit into Tuscany?

Thanks,

Matthieu



Hi Matthieu, this would be really great, i'd love for Tuscany to get a
involved with Ode to get a BPEL component.

For those that haven't found these already there's a white paper on SCA and
BPEL [1] and a specification [2].

You can see the type of thing required to implement a container for a new
component type in Tuscany by looking at some of our existing ones [3]

I agree it may be easiest for the discussions to be over here initially, but
i've subscribed to ode-dev as well anyway. I'd be very happy to help you do
this, how would you like to get started?
