I need to generate Java classes form .wsdl files (top-down) and I need to do this with XFire. I get an error, and I have heard that this is because XFire uses Spring engine to generate the classes. I don't have Spring plugin installed on Eclipse. If I get the plugin it will be enough, or I have to do something else in order for XFire to communicate with Spring, or do I have to add some sping related jar files to XFire ? Do you have some good tutorial about XFire and Spring ? Configurations and instalations are my nightmare , so please help me ! Currentlly I have the XFire1.2.6, I don't have Spring, Eclipse 3.3, and tomcat 6.0.
