+Tuscany - Getting Started - Helloworld JSONRPC Sample

+-----------------------------------------------------

+

+This sample extends the helloworld sample to make the helloworld service available as a JSON-RPC endpoint.

+JSON-RPC is a protocol for doing remote procedure calls encoded in JSON.

+

+The changes to the helloworld sample are:

+- update the pom.xml with the additional dependencies

+- update the composite to use the JSON-RPC binding 

+

+As with all the getting-started samples you can run this sample with:

+

+   mvn tuscany:run 

+

+Then at a web browser enter the following URL:

+(JSON-RPC aruguments are base64 encoded, so in this URL "WyJXb3JsZCJd" unecoded is "["World"]")

+

+   http://localhost:8080/HelloworldComponent/Helloworld?method=sayHello&params=WyJXb3JsZCJd&id=1

+

+which should return a page saying:

+

+   {"id":1,"result":"Hello World"}

+

+

+
