Currently I am evaluating number of web service frameworks in Java. I need web service framework that will help me to expose some functionality of existent application running on JBoss, The application is mostly developed using Spring and POJOs (no EJBs).
What I need is a framework having following properties:
- It should provide tools for automatic generation of boilerplate code and save time by eliminating repetitive tasks, for example tools generating WSDL from Java (java2wsdl), tools generating endpoints etc.
- Applications should be easily deployed on existent J2EE platform (JBoss), this means that it should contain as less as possible configuration files (like axis2.xml in axis2 framework).
- Also it is preferred to be able to deploy web service within .war archive of existent application. (it seems that Axis2 need a separate archive for web service app.)
- It will be very cool to use a combination of POJOs and Spring.
- Generally, the framework should have clean structure and design (for example Spring-WS lacks it), good documentation and whatever else characterizes a good piece of software.
- It is preferred that framework incorporates some standard features like JAX-WS etc. instead of vendor specific methods.
I have briefly examined
- Axis2
- Apache CXF
- and Sun's Metro
- Spring WS
But still it is difficult to decide what to use in my case:
- Axis2 seems to be so low level, it requires separate application archive and lots of configurations
- Spring WS seems to be too opaque and "sophisticated for impression purposes (?)"
- Apache CXF and Metro probably are two frameworks that I prefer to chose from but still
I need your opinion and experience about usage of some of them in a real-world applications.
