Hi, I took a look at this last night and there are a few changes to
make to get you further..
In RestaurantTest.testService() change
Node node =
NodeFactory.newInstance().createNode("Restaurant.composite").start();
to
Node node = NodeFactory.newInstance().createNode(new
Contribution("MyRestaurantContribution", "./bin")).start();
This is being more specific about where to find the contribution in
your project.
This runs and reports an error about a missing property in the
composite file. To fix this I first extended the TipServiceComponent
description...
<sca:component name="TipServiceComponent">
<sca:implementation.java
class="com.casa.comp.restaurant.impl.TipServiceImpl"/>
<sca:service name="TipService">
<sca:interface.java interface="com.casa.comp.restaurant.api.TipService"/>
</sca:service>
<!-- tipRate was missing -->
<sca:property name="tipRate" value="27.13">
</sca:property>
</sca:component>
However in the latest code this shows up an error in the XML
processing in Tuscany for some reason (I'm looking at it) so as a work
around I changed the property definition to be optional....
@Property(required=false)
public double tipRate = 27.13;
The test case now runs. Have a go and see if you can get to the same
position. I'll take a look at this XML processing issue.
Regards
Simon
