Hi Dan
Did you finish the part 3 of this refactoring ?
I'm setting up a custom JAXRS project in Eclipse and I still have to add a
wsdl4j library to the list of dependencies though I've been able to drop
quite a few dependencies compared to a similar project I set up earlier...
Just in case, here is what I'm seeing :
Caused by: org.springframework.beans.factory.BeanCreationException: Error
creating bean with name
'org.apache.cxf.transport.http_jetty.JettyHTTPTransportFactory' defined in
class path resource [META-INF/cxf/cxf-extension-http-jetty.xml]:
Initialization of bean failed; nested exception is
