My sample code fails all the time..
hello everyone,
i try to build a very simple with tuscany, but it fails all the time to be
launched and i have no idea where the errors come from. I will post my
composite file and the error msg from eclipse console.
first at all the composite definition:
------------------------------------------------------------------------------------------------------------

and following the error message:

Why does it report that component "VerarbeitungKomponent" have more than one
Service even thought that there is just one and only one. And all the
references and services cann't be seamless bound to source code.

Hallo Raymond,
thanks for your reply. I was 2 weeks on vacation and just come back.
so, i think i have solved my problem. Indeed the problem indicate to the
service name inside component. I have defined new name for the services. Not
clever but nice to know. The service name must match the service class name
and reference the variable name. It would be nice and useful if man can
define the name in the java code just like JAXB using "name" element. So
that one people can design the composite with STP without knowlage of
underlaying code and the other implement the logic on the basis of the
diagram. It could be more flexible.
1. Service Interface
@Service(name="LoginService")
public interface ILogin{
............................
}
2. Referemce
@Reference(name="oneService")
private DoClass doSerivce;
public void setdoSerice(DoClass doObj){
...........
}
3. Composite definition
<component name="OneComponent">
<service name="LoginService"> // instead of
name "ILogin"
.............
</service>
<reference name="oneService" target=".." /> // insteaf of name
"doSerivce"
</composite>
now, whats ur opinions?

Hi,
Can you show us the source code for java component implementation classes? The component service is defined by the impl class and can be further configured in the <component> element. The names have to match.
Thanks,
Raymond
