Integration

I wanna use WSDLs which I created by JDeveloper, I just create web service in JDev by using creat web service wizard.(I have DB in my project)

Then when I want to use those WSDL in OSB it says "WSDL dependencies is invalid" and the problem is related to .xsd file which created by JDev. In edit reference tab I brows "XML Schema Name" and I select suit .xsd file. But again in that .xsd it has dependency to another file which has imported to this .xsd. When I track those imported tag in each file I got there are so many .xsd which I should to import all of them first to OSB to solve that dependency problem, but I sure this is not answer for that problem. Could any body give me idea how should I solve it ?

Thanks in advance.
