Guiseppe,
You're right with regards to the xbean.xml and servicemix.xml file
usage. The only exception is a servicemix-lwcontainer SU, which also
contains a servicemix.xml config file instead of xbean.xml.
At the end of the tutorial, you have an SE ZIP file, which should be
copied into the install directory. Actually, the SA is also a ZIP file,
which contains the both SU zip files (and the META-INF/jbi.xml). You
have to copy the SA's ZIP file to the deploy directory. There's no need
to copy the SUs separately anymore, as they are already packaged inside
the SA.
Indeed, the same result can be reached using the Maven and/or Ant tasks
instead of copying the files into the install/deploy directories.

Thanks. So, using xbean.xml files for configuring SU is similar to write
servicemix.xml files for configuring the container and the components,
right? In the latter case I could personalize the container.... but from a
component perspective it's quite the same, no?
Just another thing: at the end of your tutorial, I will get two SU, one of
which depends over a SE (so, three folders) and one SA (another folder);
now, what do I copy to install directory and what to deploy? I try to
answer, correct me if I'm wrong: I will copy ZIP of SUs into install (SE's
ZIP too???) and SA's JAR into deploy. And I would reach the same result if I
would copy the ZIPs into install and then write mvn jbi:projectDeploy into
SA directory, right?
Thanks, sorry for my English (I'm Italian) and for the simple questions....

Guiseppe,
I'll try to give you a brief primer on what you should do to get this
result. If you just want to write a service to receive a message and do
something with it, you do not have to write your own service engine, you
can use the servicemix-lwcontainer or servicemix-bean component that is
included in the distribution and just build the SU/SA yourself. Anyway,
to get the SE example working...
First of all, the tutorial lets you build two things:
- a hello-world-se service engine (component), which is deployed by
copying it to ${servicemix.home}/install
- a hello-world-su service unit project
You have to add an xbean.xml file to your service unit project, to
describe the configuration for your service unit. Add an xbean.xml file
to hello-world-su/src/main/resources with this contents and rebuild the
project.
<beans
xmlns:hello="http://org.apache.servicemix.samples.helloworld.se/1.0";
xmlns:beppe="http://guiseppe.org";>
<hello:endpoint service="beppe:service" endpoint="endpoint"/>
</beans>
Now, create a second service unit project, now containing this xbean.xml:
<beans xmlns:ftp="http://servicemix.apache.org/ftp/1.0";
xmlns:beppe="http://guiseppe.org";>
<ftp:poller service="beppe:ftp" endpoint="poller"
targetService="beppe:service" targetEndpoint="endpoint"
uri="ftp://anonymous:[EMAIL PROTECTED]" />
</beans>
Afterwards, you should create another ZIP file (the service assembly),
containing both SU zip file and a file named META-INF/jbi.xml. For an
example of this file, have a look at
http://incubator.apache.org/servicemix/what-is-a-jbi-sa-and-how-do-i-create-one.html
(bottom of the page). Your file will contain two <service-unit/>
elements, one targeted towards the hello-world-se component, the other
uses servicemix-ftp.
Hope this helps,

Hi all, please help me because it's three days I'm wasting my time into
things that I think are not too difficult (but I can't do that!).
I have a simple SU, written following the tutorial about hello world SE.
My
process() method just receive a "in" message, print a phrase (using
System.out.println(...)... can I use this method to write on standard
output?) and sets exchange status to "done". I'd like to use it together
with the ready component ftp-poller... can you write me a step-by-step
guide
to do that? I'm not able to integrate, build and deploy this very simple
application... I'm a bit confused about using maven, or using ant, using
servicexml.xml... I don't exactly know what to do! Thank you very much,
Giuseppe
