I was glancing through Spring Web Services v2.0 framework reference tutorial today, and found an interesting piece of information that I’m gonna share with you all here: While writing contract-first web services i.e. developing web services that start with the XML Schema/WSDL contract first followed by the Java code second, there are four different ways […]

RPC/encoded is a vestige from before SOAP objects were defined with XML Schema. It’s not widely supported anymore. You will need to generate the stubs using Apache Axis 1.0, which is from the same era. java org.apache.axis.wsdl.WSDL2Java http://someurl?WSDL You will need the following jars or equivalents in the -cp classpath param: axis-1.4.jar commons-logging-1.1.ja commons-discovery-0.2.jar jaxrpc-1.1.jar saaj-1.1.jar wsdl4j-1.4.jar activation-1.1.jar […]
