Newb: Need help with rest binding
moraleslos Jul 10, 2013 2:40 PMHi all,
I'm a total newb with SY and am following the rest-binding example for the quickstart but I'm not sure how everything works out. I would like to create a simple service in SY that, when invoked by some outside source, calls an external REST service.
So say I have this external REST service I would like to use: http://host.com/rest/services/GeocodeServer/findCity?x=____&y=_____
Now in SY, I want to create essentially a facade that will receive the x and y coordinates, invoke the above external REST service with the passed-in coordinates, and then return a result which is essentially a POJO that has city information. The SY service looks something like this:
Town findTownInformation(String x, String y)
Where Town is just a POJO containing basic properties.
Now looking at the example I need to create a service, it's implementation, and a reference to the external Web Service. So far this is how my example SY.xml looks like:
<?xml version="1.0" encoding="UTF-8"?>
<switchyard xmlns="urn:switchyard-config:switchyard:1.0" xmlns:bean="urn:switchyard-component-bean:config:1.0" xmlns:sca="http://docs.oasis-open.org/ns/opencsa/sca/200912" name="switchyard-rest-example" targetNamespace="urn:com.example.switchyard:switchyard-rest-example:0.0.1-SNAPSHOT">
<sca:composite name="switchyard-rest-example" targetNamespace="urn:com.example.switchyard:switchyard-rest-example:0.0.1-SNAPSHOT">
<sca:component name="InvokeRestServiceBean">
<bean:implementation.bean class="com.example.switchyard.switchyard_rest_example.InvokeRestServiceBean"/>
<sca:service name="InvokeRestService">
<sca:interface.java interface="com.example.switchyard.switchyard_rest_example.InvokeRestService"/>
</sca:service>
<sca:reference name="InvokeRestServiceReference">
<sca:interface.java interface="com.example.switchyard.switchyard_rest_example.InvokeRestServiceReference"/>
</sca:reference>
</sca:component>
</sca:composite>
</switchyard>
I'm totally stuck at this point. Any help would be appreciated. TIA.
