Hi , I am basically new to Qvto but trying to do a transformation between SoaML and WSDL . This is what I have done so far but i get an error that i dont know how to solve


transformation SampleSOAML(in soamlin: UML, out wsdlout: wsdl);



main() {

soamlin.rootObjects()[Participant]->map SoaML2wsdl();

}

mapping Participant::SoaML2wsdl() : wsdl::Definition {




self.base_Class.ownedPort-> forEach(p){

p.type.getAppliedStereotypes()-> forEach(s){

log("Type " + s.name);


self.base_Class.ownedPort.type.oclAsType(Class)-> map ToService();

}

I get the error of cannot find the operation ToService for the type bag class neither for its element class . hoz to solve this?

Hi

If you invoke ToService you need to implement it.

Unfortunately there is very little tutorial material for QVTo. The QVT
1.3 spec is clearer and more accurate than its predecessors, but not a
tutorial. You probably need to do as other users do and study the
provided SimpleUML to RDBMS example and its helpful comments.

Regards
