At the moment, the DAS service is the "static das contract" that gets
assigned to every <implementation.das> component and allows you to
perform simple CRUD operations. The other service interfaces are added
at the moment by the componentType side file, that must match the das
config file name.... so, if you have something like :
...
<component name="DASServiceComponent">
<tuscany:implementation.das config="company.xml" dataAccessType="rdb">
<tuscany:connectionInfo>
<tuscany:connectionProperties
driverClass="org.apache.derby.jdbc.EmbeddedDriver"
databaseURL="jdbc:derby:target/test-classes/dastest; create = true"
loginTimeout="600000"/>
</tuscany:connectionInfo>
</tuscany:implementation.das>
</component>
...
Then you should define the services in a company.componentType side file
<service name="CompanyService">
<interface.java
interface="org.apache.tuscany.sca.implementation.das.company.CompanyService"/>
</service>
You should also be using recent trunk code, as I have recently fixed
couple issues on this area. The test cases from implementation.das and
customer-map demo should also be a reference for you.
Let me know if it works for you, and if you have other questions...
