Hi,

I'd recommend you to take a look on the Apache Camel (FUSE Mediation Router) web service proxy sample available at http://camel.apache.org/cxf-proxy-example.html

Then you can host that web service proxy on FUSE ESB (ServiceMix).

There is also a thread that Claus Ibsen responded a similar question mentioning the reasons to follow that approach http://stackoverflow.com/questions/5939067/using-servicemix-to-proxy-remote-web-service ).

Hope this helps,

-Marcelo

Hi thanks for the help. I'm able to deploy the artifact into fuse esb 4.3.0, but when i try to start it i get this message

karaf@root> Exception in thread "SpringOsgiExtenderThread-17" java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 're

Is there some feature or bundle I need to install to get this to work in Fuse?

Thanks in advance.

Hi,

We do have explicit instructions to be running 4.3.

In the servicemix.log,

this error seems to be what is causing the problem.

13:12:51,619 | ERROR | xtenderThread-17 | ContextLoaderListener | 72 - org.springframework.osgi.extender - 1.2.0 | Application context refresh failed (OsgiBundleXmlApplicationContext(bundle=org.apache.camel.proxy, config=osgibundle:/META-INF/spring/*.xml))

Hi, we are using camel route.

Here is the camel-config.xml

...

<cxf:cxfEndpoint id="reportIncident"
address="http://localhost:${proxy.port}/cxs"
endpointName="s:Port"
serviceName="s:Service"
wsdlURL="etc/ts.wsdl"
xmlns:s="http://cxs/ts.wsdl"/>

<camelContext xmlns="http://camel.apache.org/schema/spring">

<propertyPlaceholder id="properties" location="classpath:incident.properties,file:target/custom.properties"/>

<endpoint id="callRealWebService" uri="http://cxs.com:7777/Service"/>

<route>
<!-- CXF consumer using MESSAGE format -->
<from uri="cxf:bean:reportIncident?dataFormat=MESSAGE"/>
<!-- log input received -->
<to uri="log:input"/>

<!-- send proxied request to real web service -->
<to ref="callRealWebService"/>
<!-- log answer from real web service -->
<to uri="log:output"/>
</route>

</camelContext>

...

Quick backtrack...

In the example linked below,

http://camel.apache.org/cxf-proxy-example.html

I am able to run it using mvn camel:run.

Question is, how do I then deploy this example to run in fuse esb servicemix?

Hi,

I added the plugin you suggested to my pom file, but still same error when I try to start the bundle.

i installed the

camel-cxf
camel-http
camel-spring

as you can see by the lines below

200 Active [ ] [ ] 60 camel-cxf (2.6.0.fuse-03-01)
201 Active [ ] [ ] 60 camel-http (2.6.0.fuse-03-01)
204 Active [ ] [ ] 60 camel-spring (2.6.0.fuse-03-01)
205 Installed [ ] [ ] 60 camel-example-cxf-proxy (2.7.1.fuse-00-27)

when i run

karaf@root> osgi:start 205

this error occurs, and I cannot figure out what I am missing or doing wrong.

Please help! Thanks a lot in advance!!

The pom and camel-config are straight from the camel-example-cxf-proxy with the one plugin you had me put in.

To deploy the bundle, i did a "mvn install" and then copied the jar into the "deploy" folder of servicemix.

It installs, but is unable to start with that error message.

Hi, I tried what you said and still the same error.

Very interesting. I have been installing it thru $SMX/deploy and also by typing this

karaf@root> osgi:install mvn:org.apache.camel/camel-example-cxf-proxy

However, both ways did not work.

Once I added the "/2.6.0" like you did, it is able to start.

Thank you for the help, although I am puzzled as to why it works.
