With the Oracle Service Bus the Oracle Workshop is supplied to the develop services. The workshop is based on Eclipse. When developing BPEL processes with JDeveloper, you could easily import WSDL's from other systems by using local file definitions or directly via the URL. Using the URL option, give you the advandtage that also the import XSD are read. Wit JDeveloper this was done automaticly. The tutorials of the Oracle Service Bus Workshop, assumes that you are using local files for the XSD and WSDL definitions.
It is possible to read the WSDL defintions directly from the URL (URI). This is done as follows, assuming you have opened the workshop, create an ALSB service with all the folders.
Right click on the Proxy Folder -> New -> Proxy Service
In the next screen select WSDL and click on browse. Click in Consume to load an external WSDL definition.
The next screen shows you the WSDL definitions already known in your project
In the next screen, Select from the " Service Consumption" the URI option, enter the WSDL URL and click on 'Ok'. Now the WSDL files and XSD are loaded into your sevice definition.
Note: When you load WSDL definitions from BPEL, you should remove manually the partnerlinks in your OSB project. See also this article.
