[resolved] REST service proxy route

[Anonymous]

Hello!
Using Talend ESB, I want to proxy my REST service that is deployed, for example, on: http://hostnameA:8080/web_app to http://hostnameB:8085/web_app. That means, when I want to invoke the service (http://hostnameA:8080/web_app), I need to invoke them on: http://hostnameB:8085/web_app. It is just a simple proxy route.
I tried to do this using TOS and Talend ESB Studio, but without result. I tried something similar with Axis web services and works fine. My configuration for this case was:
Part of camel-config.xml file

address="http://proxy_hostname:8090/application/service/TokenService"
endpointName="service"
serviceName="s:TokenService"
wsdlURL="etc/TokenService.wsdl"
xmlns:s="http://tempo.intalio.org/security/tokenService/"/>


serviceName="serviceNS:TokenService"
endpointName="serviceNService" address="http://hostname:8080/axis2/services/TokenService">

....

Can someone help me?
Thanks in advance!

Hi,
Can you give us a little bit more details on what is not working actually ?

Hi,
I have a REST service deployed on http://hostname:8080/alfresco/service/service_name/process/{instanceId}/doctypes/{doctype} with,as you can see, 2 parameters. I want to publish this service on Talend ESB and proxy them on different hostname and (or) port.
I've tried with a job that call this service using the tREST component, exported them as an OSGi bundle for ESB and deployed on ESB. When I invoke them with "job:start job_name" command it works fine. Shows the expected response (link in string format). I think this is not a right solution to proxy a REST service.
How can I invoke this job remotely from another application? Is there any other better solutions to proxy a REST service using Talend ESB? Can I use the Route Builder within Talend ESB Studio to create a simple proxy route? If yes, how? Is there any example?
Thanks

Hi
You can probably just use simpler Camel HTTP or Jetty components for a simple proxying.
I'm not sure if you can use CXF components in the from: mode when WSDL2 is used to describe a RESTful endpoint.
Alternatively please also consider using to:cxfrs:uri, instead of just to:uri, though to:uri should work, the problem seems to be on the from: end

Hi,
I think you can do it directly on the RouteBuilder :
- Create a cMessagingEndpoint, set the URI as follow :
"cxf://http://KarafHostName:KarafPort/webserviceEndpoint?wsdlURL=file:///pathToMyWSDL/file.wsdl&dataFormat=MESSAGE"
This messaging endpoint is the proxy service entry point.
- Create a cMessagingEndpoint, set the URI to your REST Web service :
"cxf://http://RESTHostName:RestPortt/RestWebserviceEndpoint?dataFormat=MESSAGE"

Connect the two cMessagingEndpoint and run.

@ bahaaldine: if using TESB 4.2.0, maybe a patch about CXF is needed to make the Route work. And in the next release of TESB, Route with CXF will run without any workaround.

Hi bahaaldine,
should I implement a service and write a WSDL for my REST service which I will expose on ESB or? I don't understand.
I tried with this configuration:
First cMessagingEndpoint:
"cxf://http://localhost:18081/applicationName/service/serviceName/process?dataFormat=MESSAGE"
Second cMessagingEndpoint:
"cxf://http://mashina:8080/applicationName/service/serviceName/process?dataFormat=MESSAGE"
The error I get is: "Failed to create route cMessagingEndpoint_1: Route[[From[cxf://http://localhost:18081/alfresco/service/ab... because of Failed to resolve endpoint: cxf://http://localhost:18081/alfresco/service/abitecm/process?dataFormat=MESSAGE due to: No component found with scheme: cxf" (Error within Talend Route Builder when I press Run)
Then I have tried without "cxf" prefix in uri. No errors.
When I invoke the endpoint: http://localhost:18081/applicationName/service/serviceName/process/{parameter1}/doctypes/{parameter2}
nothing happens (Firefox REST client)
KarafHostName: localhost
KarafPort: 18081
I deployed the route on Talend ESB and invoked again the endpoint. The error I get then is:
"

I do not know if I have well explained what I need?!
