Hi,
I am having problems migrating from CXF 2.2.12 to 2.6.x and would like advice
on how best to proceed. My servlet configuration and jaxrs:server configuration
that was working with 2.2.12 does not work with 2.6.x
I have the following servlet:
<servlet>
<servlet-name>CXFServlet</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/rs/*</url-pattern>
<url-pattern>/preference-rest/*</url-pattern>
</servlet-mapping>
I have the following jaxrs:server config:
<jaxrs:server id="wap2" address="/">
<jaxrs:serviceBeans>
<ref bean="systemDashletRESTImpl"/>
<ref bean="userPreference"/>
</jaxrs:serviceBeans>
<jaxrs:providers>
<ref bean="jsonProvider6" />
<ref bean="i18nWebAppExcMapper" />
</jaxrs:providers>
<jaxrs:extensionMappings>
<entry key="json" value="application/json"/>
</jaxrs:extensionMappings>
The clients of userPreference call URL containing "/preference-rest/".
The clients of systemDashletRESTImpl call URL containing "/rs/".
I have found that the calls to the systemDashletRESTImpl fail with this message:
[2014-09-22 04:31:32,616] [http-bio-443-exec-5] [JAXRSInInterceptor] [WARN ] -
No root resource matching request path /webacs/rs/system-rest/getsysteminfo has
been found, Relative Path: /webacs/rs/system-rest/getsysteminfo. Please enable
FINE/TRACE log level for more details.
In debugger I can see the issue is related to:
org.apache.cxf.transport.http.DestinationImpl where the destinations field is a
Map between URL and AbstractHTTPDestination. Because systemDashletRESTImpl and
userPreference are both using the address '/' what happens is that the value
held in the destinations field is that for the preferences resource and the
systemDashletRESTImpl resource entry gets overwritten.
Is this a regression in CXF? This configuration all works in CXF 2.2.12.
Do you mean that the issue occurs when a request with URI containing a
'/preference-rest/' is issued first, followed by a request with URI
containing '/rs' or the other way around ?
What happens in CXF up until 3.0.0 is that CXFServlet overrides the
destination addresses by default which has side-effects in cases when
more than one HTTP route into a given endpoint is available.
Can you advise on how I can get this working with 2.6.x? Preferably without any
of the resource URLs changing (as I do not want to change the client code) and
preferably without any change to the resource code. Is there something I can do
in CXF configuration to get this working again? E.g. Implement resource
comparator?
Adding a "disable-address-updates" servlet init parameter with a value
true will fix it.
By the way, CXF 2.6.x has reached the end of life, perhaps you should
consider migrating to CXF 2.7.x at least.
HTH, Sergey
Thanks
