There is 2 servlet CXFServlet 
org.apache.cxf.transport.servlet.CXFServlet in web.xml, each one has at 
least a REST service.
Each CXFServlet has its own file beans.xml to describe the service via 
spring.

web.xml
  <servlet>
    <description>Apache CXF1 Endpoint</description>
    <display-name>cxf1</display-name>
    <servlet-name>cxf1</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>cxf1</servlet-name>
    <url-pattern>/services1/*</url-pattern>
  </servlet-mapping>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/beans1</param-value>
  </context-param>
  <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <servlet>
    <description>Apache CXF2 Endpoint</description>
    <display-name>cxf2</display-name>
    <servlet-name>cxf2</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    <init-param>
        <param-name>config-location</param-name>
        <param-value>/WEB-INF/beans2.xml</param-value>
    </init-param>
    <load-on-startup>2</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>cxf2</servlet-name>
    <url-pattern>/services2/*</url-pattern>
  </servlet-mapping>



When one of the CXFServlet has no REST service (only SOAP), there is no 
error.
