Additional samples under sandbox/sebastien/java/samples/

[Jean-Sebastien Delfino <js...@apache.org>]

I checked in two new "technology" samples under 
sandbox/sebastien/java/samples/:
- calculator - demonstrates wiring multiple components together (a 
calculator service is assembled with add, subtract, multiply, and divide 
services).
- customerinfo - demonstrates the creation of an SDO DataObject defined 
by an XSD and the use of dynamic SDO APIs in an SCA component (as 
described in TUSCANY-284).

While developing the customerinfo sample I realized the importance of 
fixing TUSCANY-179 (need an @SDOHelper annotation to inject an SDO 
helper into a component). Without this annotation, a component cannot 
access the TypeHelper populated by <import.sdo> elements, and therefore 
cannot use the types defined by XSDs at all. I put an ugly workaround in 
the sample for now (reload the XSD into the global XSDHelper.INSTANCE) 
and raised the priority of TUSCANY-179 to critical.

Could you please take a look at these samples. Feedback welcome. If 
there's no objection I'm planning on moving them to the main 
java/sca/samples directory at the end of the day tomorrow.

+1 to move them up.

Do you have a code snippet to just grab an instance of an SDO helper?  
If we can post it to the JIRA issue assign it to me and I'll write  
the injector.
