I'm relatively new to Camel. I did research what I am attempting to do, but
did not find much help.
The goal is to take an existing standalone CXF rest service (with many
service beans) and split it into multiple independent CXF rest services
coordinated by Camel.
As an initial step, I am attempting to front the existing service with
Camel. So to be clear, at this stage, I only want to pass HTTP requests
from Camel down to the CXF service. To this end I have run into multiple
issues. I am currently unable to route the HTTP message received by Camel
to the CXF service.
My route:
<route>
<from
uri="servlet:///rest?servletName=CamelAPI&matchOnUriPrefix=true" />
<to uri="ref:message-logger" />
<setBody><simple>CamelHttpServletRequest</simple></setBody>
<to uri="ref:message-logger" />
<to uri="direct:api" />
</route>
I have configured CXF using camel's transport factory using:
<bean
class="org.apache.camel.component.cxf.transport.CamelTransportFactory">
<property name="bus" ref="cxf" />
<property name="camelContext" ref="camelContext" />
<property name="checkException" value="true" />
<property name="transportIds">
<list>
<value>http://cxf.apache.org/transports/camel</value>
</list>
</property>
</bean>
This was required to get around some earlier issues I ran into. My CXF
service is configured like:
<jaxrs:server id="restService" address="direct:api">
<jaxrs:serviceBeans>
...
Startup is fine. On attempting to hit the servlet via RESTClient I can see
the message I passed in logged correctly. However, the CXF service cannot
receive the message. The error is:
No consumers available on endpoint: Endpoint[direct://api] to process:
Exchange ...
Any help is greatly appreciated.
This is an interesting idea, to try to use a 'direct' URI scheme as
jaxrs server endpoint. I don't think it works right now, and I'm not
sure what has to be done yet, but definitely worth investigating...
In meantime, using Camel transport scheme will do, try something like this:
<jaxrs:server id="hello_rest"
address="camel://direct:HelloWorldRestServerEndpoint">
<!-- usual declarations here -->
</jaxrs:server>
<!-- Camel routes from addresses on the servlet to rest and jaxws
servers -->
<camelContext id="camelContext"
xmlns="http://camel.apache.org/schema/spring"; trace="false">
<route>
<from uri="servlet:///HelloWorld?matchOnUriPrefix=true"/>
<to uri="direct:HelloWorldRestServerEndpoint"/>
</route>
</camelContext>
