The cxfbean-component no longer works in OSGI (failure to auto create and
NullPointerException)
-----------------------------------------------------------------------------------------------
Key: CAMEL-4299
URL: https://issues.apache.org/jira/browse/CAMEL-4299
Project: Camel
Issue Type: Bug
Components: camel-cxf, osgi
Affects Versions: 2.8.0
Environment: Karaf 2.2.0 (with a jre.properties modified to work with
cxf)
Reporter: Jonas Bengtsson
Camel fails to auto create the cxfbean-component. I have tried both with
blueprint and Spring-DM. For Spring-DM i get the following error:
Cannot auto create component: cxfbean
My Spring XML-file:
{code}
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:camel="http://camel.apache.org/schema/spring";
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://camel.apache.org/schema/spring
http://camel.apache.org/schema/spring/camel-spring.xsd";>
<camel:camelContext>
<camel:route>
<camel:from
uri="jetty:http://0.0.0.0:8080?matchOnUriPrefix=true"; />
<camel:to uri="cxfbean:myBean" />
</camel:route>
</camel:camelContext>
<bean id="myBean" class="mypackage.MyJaxRsAnnotatedBean" />
</beans>
{code}
I have both the camel-cxf and camel-cxf-transport bundles installed and it
seems that both of them have a ComponentResolver for cxfbean published in the
OSGI-registry. I can get my bundle to start if I create the cxfbean-component
explicity in my Spring- or blueprint-XML file:
{code}
<bean id="cxfbean"
class="org.apache.camel.component.cxf.cxfbean.CxfBeanComponent" />
{code}
But then I will get a NullPointerException when I visit a URL handled by my
JAXRS-annotated bean:
