I am normally used to using JSON/REST. I have been given access to a web service with WSDL file that I need to use to read data. I have no idea where to start
What is the quickest easiest way to get JAVA code up and running that can query this web “service”?
You can use libraries like Apache AXIS or Apache CXF, which include a WSDL2Java program you can run to parse the WSDL definition file and generate classes that let you invoke the web service.
