Apache Felix OSGI servlet bridge failing after 3.3.5 version upgrade

[Sandeep Ambule <sa...@gmail.com>]

Hi Team,

I have upgraded CXF version in our working application from 3.3.4 to 3.3.5
but after upgrading not able to access any URL.

we have OsgiCxfNonSpringJaxrsServlet which extends CXFNonSpringJaxrsServlet
and override below method

protected void createServerFromApplication(String cName, ServletConfig
servletConfig) throws ServletException {


JAXRSServerFactoryBean bean =
ResourceUtils.createApplication(odataApplication,
MessageUtils.isTrue(ignoreParam),
getStaticSubResolutionValue(servletConfig), false,null);


String splitChar = getParameterSplitChar(servletConfig);
setAllInterceptors(bean, servletConfig, splitChar);
setInvoker(bean, servletConfig);
setExtensions(bean, servletConfig);
setDocLocation(bean, servletConfig);
setSchemasLocations(bean, servletConfig);

bean.setBus(getBus());

bean.create();
}


in 3.3.4 it was working fine but in 3.3.5 servlet init failed and giving
below error
used by: org.apache.felix.log.LogException:
org.apache.cxf.service.factory.ServiceConstructionException: There is an
endpoint already running on /.


solved above issue by providing diffrent address like below
bean.setAddress(address);

Not all the servlet showing registered but not able to access any of the
URL getting 404

Please find proxy servlet snippet from web.xml

<listener>

<listener-class>org.apache.felix.http.proxy.ProxyListener</listener-class>
    </listener>

    <filter>
<filter-name>WebConsoleFilter</filter-name>
<filter-class>com.sap.banking.web.console.filter.WebConsoleFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>WebConsoleFilter</filter-name>
<url-pattern>/system/console/*</url-pattern>
<url-pattern>/system/console</url-pattern>
</filter-mapping>

    <servlet>
        <servlet-name>proxy</servlet-name>

<servlet-class>org.apache.felix.http.proxy.ProxyServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>proxy</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>


application is working fine with cxf 3.3.4 but in 3.3.5 it's breaking, is
there any changes related to proxy servlet or whiteboarding in 3.3.5?

also observed org.apache.cxf.transport.servlet.CXFNonSpringServlet with
path '/cxf' get registred by default in  Servlet Context
'org.osgi.service.http' Registered Servlet Services
which might causing this issue.

Please help me with this upgrade.


Thanks & Regards,

Hi Sandeep,

There were minor changes in the CXFNonSpringJaxrsServlet (between 3.3.4 and 3.3.5) to use 
provided DestinationRegistry but it seems like it should not trigger in your particular 
case. Could you please share a reproducer for the problem? Also, it is not clear how the 
deployment environment (container(s) / version(s)) looks like, thank you.

Best Regards,
