Zero code proxy service

[saliya]

Hi,

I have a SOAP Web service back end and I want it to be exposed via Jboss ESB through a proxy service. So in my scenario Jboss ESB will have a proxy Web service giving the same interface as that of the original service.

The way I could do this was only by writing Java code. But I guess there should be an easy way with less code (ideally no code) to do this.

I look into the quick start samples and couldn't find a nice to way to achieve my scenario. If someone can help me on this I'll be very much grateful. A SOAP scenario sample would do fine too.

Thanks in advance
Saliya

Hiya Saliya.

Is this WSO2 trying to do a performance test again?

Hi Saliya, would a http router suit your need in this case? You may want to check the static_router/simple_cbr demo out. In JBossBSB, any ESB service can be exposed as web servcies (SOAP). I shall be able to provide more concrete helps if you can elaborate a little bit more details on your exact scenario.

Hi Jervisliu,

Thanks for the help. I looked into the static_router sample in quickstarts/static_router folder in JBoss ESB but I couldn't find any simple_cbr demo.

Anyway I'll make my scenario simple as follows.

1. I have an echo service which simply returns any incoming SOAP payload and runs on localhost:8085/MockServices/EchoService.

2. I want the above service to be exposed via a different endpoint using JBoss ESB. An example endpoint would be localhost:8080/webservice_proxy/EchoProxy

Thus any SOAP message I send to localhost:8080/webservice_proxy/EchoProxy service will be routed to localhost:8080/MockService/EchoService. I was able to do this by writing a Java class extending the AbstractActionLifecycle class and invoking the desired back end service (the EchoService) from it.

I would like to know if this scenario is possible to implement without writing Java stuff.

Thanks in advance,
Saliya

Hi saliya, if you can wait for 1 or 2 days, you can try the HttpRouter. There is a minor bug in HttpRouter that can not handle HttpHeaders properly, I fixed it but have not got chance to check in yet, the svn is down at the moment.

The configuration should look like below roughly:

<service category="MyServiceCategory" name="MyWSProducerService1" description="WS Frontend speaks natively to the ESB" invmScope="GLOBAL">

 <listeners>
 <jbr-listener name="Http-Gateway" busidref="Http-1" is-gateway="true"/>
 </listeners>
 <actions>
 <action name="JBossWSAdapter" class="org.jboss.soa.esb.actions.routing.http.HttpRouter">
 <property name="endpointUrl" value="localhost:8080/anotherService"/>
 <property name="method" value="POST"/>
 </action>
 </actions>
 </service>

Also please feel free to email me directly jliu at redhat.com, if you have any further questions.

Hi Jervisliu,

I am really thankful for the help (yep I sure can wait for couple days). I will let you know the results ASAP.

Thanks again,

Saliya
