Hi friend,
Recently, I've done a JDE with Salesforce Cloud integration, through BSSV both inbound and outbound communication with Soap technology. Salesforce use Apex (Oracle Application Express) for integrations
One of the main problems that I found was generate proxy client, the Organization WSDL has a lot of methods (this service is the principal , and it is used for all access related: login, logout, sessions, userinfo, etc), and besides that when trying to generate proxy client in JDeveloper 12c (12.2.1.3.0) it gave errors to namespaces conflicts.
So, I decided try alternate path, using JAVA wsimport tool, it tool from the file or IP WSDL will generate us a package java .jar with all classes and method services, it package we could import to a ower bssv project as external library and works comfortable.
You can look a lot of information about the use of it java tool:
https://docs.oracle.com/javase/7/docs/technotes/tools/share/wsimport.html
https://mkyong.com/webservices/jax-ws/jax-ws-wsimport-tool-example/

And more specific for Salesforce service:

I recommend, java version it's the same for wsimport and JDeveloper configured for your JDE enviroment ( it can do directly with the java executable version in JDE machine or add java version path on the PATH operative system).
Execution example:
wsimport -b bindings.xjb -keep -B-XautoNameResolution -XadditionalHeaders -Xdebug OrganizationDEV.wsdl -clientjar SalesForceOrganizationDEVWSDLConnector.jar
Donde
wsimport: java command for class generation from wsdl
-b: specify link files jaxws/jaxb or additional schemes
bindings.xjb: link file or additional schemes
-keep: keep generated files
-B-XautoNameResolution: JAXB instructions to automatically resolve names conflicts.
-XadditionalHeaders: generates header parameters in request methods
-Xdebug: print debug information
OrganizationDEV.wsdl: wsdl file with service information
-clientjar: make jar file with artifacts generated together WSDL metadata for call web service.
SalesForceOrganizationDEVWSDLConnector.jar: jar file will generate with all java class and wsdl to project import.
bindings.xjb file will depends from namespaces and transformations to do.
bindings.xjb
<?xml version="1.0" encoding="UTF-8"?>
<bindings
wsdlLocation="wsdlcalidad.wsdl"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://java.sun.com/xml/ns/jaxws">
<bindings node="//xsd:schema[@targetNamespace='urn:sobject.enterprise.soap.sforce.com']">
<jaxb:globalBindings generateElementProperty="false" underscoreBinding="asCharInWord"/>
</bindings>
</bindings>
Other example:
<?xml version="1.0" encoding="UTF-8"?>
<bindings
wsdlLocation="INTProducto_JDE.wsdl"
xmlns:jaxb="http://java.sun.com/xml/ns/jaxb"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://java.sun.com/xml/ns/jaxws">
<bindings node="//xsd:schema[@targetNamespace='http://soap.sforce.com/schemas/class/INTProducto_JDE']">
<jaxb:globalBindings generateElementProperty="false" underscoreBinding="asCharInWord"/>
<jaxb:schemaBindings>
<jaxb:nameXmlTransform>
<jaxb:typeName suffix="Type" />
</jaxb:nameXmlTransform>
</jaxb:schemaBindings>
</bindings>
<bindings node="//xsd:schema[@targetNamespace='http://soap.sforce.com/schemas/class/INTResponse']">
<jaxb:globalBindings generateElementProperty="false" underscoreBinding="asCharInWord"/>
<jaxb:schemaBindings>
<jaxb:nameXmlTransform>
<jaxb:typeName suffix="Type" />
</jaxb:nameXmlTransform>
</jaxb:schemaBindings>
</bindings>
<enableWrapperStyle>false</enableWrapperStyle>
<enableAsyncMapping>false</enableAsyncMapping>
</bindings>
And finally, you import jar file to project, adding libraries for deploy and start to use classes and method to call service.
I hope it is useful for you friend.
Best regards.
