Hi!
Another question regarding properties of components, this time about
properties that are not simple XSD types and that are injected with XML
data.
With a look at the property tests in the itest directory in the source
distribution, I tried this:
In the composite file (inside a component):
...
<property name="person" element="ivan:person">
<person xmlns="http://www.ivan.com/person";>
<firstName>DeeDee</firstName>
<lastName>Ramone</lastName>
<age>49</age>
</person>
</property>
</component>
...
In the component implementation class; the field to be injected:
@Property(name="person", required=false)
protected Person mPerson;
Then I have a class Person which contains two string fields firstName,
lastName and one integer field age with corresponding getters and
setters. No annotations.
In the same directory as the composite, I have the following XML schema:
<?xml version="1.0" encoding="UTF-8"?>
<schema
xmlns="http://www.w3.org/2001/XMLSchema";
xmlns:ivan="http://www.ivan.com/person";
targetNamespace="http://www.ivan.com/person";
attributeFormDefault="unqualified">
<element name="person" type="ivan:Person"/>
<complexType name="Person">
<sequence>
<element name="firstName" type="string" nillable="false"/>
<element name="lastName" type="string" nillable="false"/>
<element name="age" type="int"/>
</sequence>
</complexType>
</schema>
Finally, when I run the program, I there is the following exception:
Exception in thread "main" java.lang.IllegalStateException:
org.apache.tuscany.sca.assembly.builder.CompositeBuilderException:

I have also tried the tests in the itest/properties, which I seriously
doubt that they ever have been able to pass given that there is no XML
schema defining the type/element used in the composite.
If anyone has any hints, I would be very grateful. Feel like I have
tried "everything", but I am sure there is something I overlooked.
Best regards!
Ivan
