Hello there,

I'm trying to implement the introducing-tours example from the
TuscanySCAInAction book.

There is a tours.composite file in an Eclipse project called
"Tours" which references a service like this:

<?xml version="1.0" encoding="UTF-8"? <sca:composite
xmlns:sca="http://www.osoa.org/xmlns/sca/1.0" name="tours" targetNamespace="http://tuscanyscatours.com/"
<sca:component name="TripBooking"

<sca:reference name="mytrips" target="TripProvider/Trips"
<sca:interface.java interface="com.tripprovider.Trips" /
</sca:reference

</sca:component

</sca:composite

When I use the SCA Builder or try to open the composite in the
SCA composite model editor, I get an
UnresolvedReferenceException for mytrips and the project
is marked as having an error.

I guess this happens because the service that is referenced
sits in another Eclipse project (Trips). Adding a project
reference from Tours to Trips doesn't help, neither
does adding the Trips jar file to the project libraries.

I was planning a larger development project and was intending
to use one Eclipse project for each composite. This
seemed a natural way to go. If this is technically not feasible,
what do people usually do in Eclipse?

I can't believe the SCA Tools would force one
into putting everything into one single gigantic project.

Hi Sebastian,

This is a bug. As you said, a reference from a composite to a composite
located in another project or in a jar file should work.
Can you please fill in a bug?

Thanks.
