Hi, I am new to service mix 4.4.1. So am in the learning process. What i am trying to do is, from a web serivce am trying to get a soap input and using service mix i want to convert that soap input into json and display it.

I tried doing it but i am facing a few problems,

Getting an exception as follows


karaf@root> Exception in thread "SpringOsgiExtenderThread-4" org.springframework.beans.factory.BeanCreationException: Error creating be

Re: Null pointer exception

Hi,

This exception indicates that something wrong when you publish your  
jaxws endpoint, the servicemodel isn't correct.

Can't tell so much only with this exception.

We have a couple of examples shipped with kit, which should be a good  
start for you. Especially the cxf-osgi example which demonstrate how  
to deploy the jaxws endpoint into OSGi, also there are several camel  
related examples which is useful when you wanna transform the message  
payload in SMX.
