We are trying to take out all the annotations from our classes and configure it in a spring-config.xml.

spring-config.xml looks like

<jaxrs:server id="restServer" address="/rest/">
        <jaxrs:model id="restModel">
            <jaxrs:resource name="com.csc.fs.rest.contact.RetrieveContactHistoryBP" path="retrieveContactHistoryBP">
                <jaxrs:operation name="retrieve" path="{partyId}" consumes="application/json" produces="application/json" verb="GET">
                    <jaxrs:param name="req" type="CONTEXT"/>
                    <jaxrs:param name="partyId" type="PATH"/>
                </jaxrs:operation>
            </jaxrs:resource>
            <jaxrs:resource name="com.csc.fs.rest.contact.StartContactBP" path="startContactBP">
                <jaxrs:operation name="startContact" path="/" consumes="application/json" produces="application/json" verb="PUT">
                    <jaxrs:param name="req" type="CONTEXT"/>
                    <jaxrs:param name="startContact" type="REQUEST_BODY"/>
                </jaxrs:operation>
            </jaxrs:resource>
        </jaxrs:model>
        <jaxrs:serviceBeans>

now when i click on the exposed service : enter image description here

i get the following trace :
