@VTS I recommend you follow some other example for getting RESTful services working with Spring as this post is a bit almost 3 years old. Look into something like http://bit.ly/u9JbyD . I had already mentioned where the dependencies are as part of this post http://raulrajatutorials.googlecode.com/svn/trunk/raulraja.com.tutorials/pom.xml , you can get the CXF list of dependencies there.

Which is the cxf jar version are you using? Iam getting cvc-complex-type.2.4.c no declaration error for jaxrs:server, cxf:bus and jaxws:endpoint….

@VTS I have no idea what your error is about. I neither use IBM WS nor there is a META-INF/ws-server-components.xml file in this example.

Thanks Raja that helps for basic understanding, may post more questions down the line.

@JavaDev REST is not a framework but a style of consuming and exposing WebServices. http://en.wikipedia.org/wiki/Representational_state_transfer
CXF is just a project that aids in building web services. There are multiple other projects and framework for building web services. The fact that a service returns XML or JSON has nothing to do with REST. REST services can also return XML even though they are most commonly found in JSON format. Legacy services usually are found as SOAP services http://en.wikipedia.org/wiki/SOAP
REST style services such as the one shown in this article can use SOAP and still be consider REST. Unfortunately REST, SOAP, JSON, … have become buzz words that non developer roles (sales, project managers…) in this industry misuse and butcher or just simply confuse. My advice is that you choose the right solution for the problem you’re trying to solve, and shy away from turning your legacy WS to a REST style just for the sake of it.

I am new to webservice world. The requirement of project is to use REST framework in order to expose Legacy services as web services. I am confused about ‘REST with cxf’ OR simply ‘REST’ will do the work for me. Also existing legacy services return response in XML format but we want these new webservices to return JSON . Kindly guide and assist.

@Shamana Also make sure that all methods that are being proxied are declared on a interface. Depending on your spring config you may be using JDK dynamic proxies or cglib class based proxies. Your AOP auto proxy config may also affect this and I’ve seen similar exceptions in the past similar to yours due to lack of interfaces or use/lack of use of Spring AOP’ autoproxying capabilities.

Thanks Raul, all that looks good to me, upgraded JDK to 6 now and atleast I am not getting this proxy error.
But I have! to use JDK1.5.10, I will try to upgrade cxf to 2.4.3 with JDK1.5.10 and try again.

@Shamama, looks like your exception is unrelated. Maybe you are referencing ‘fulfillPAYGMultim’ as a bean dependency but you don’t have a bean with that name. Double check your id references are correct.
