  • Create a new file demo.xrpc in the webapp directory. On translation, this will generate a xml-rpc servlet class.
<xrpc:api namespace="demo">
  <page:controller class="MY_XMLRPC_API" />
  <xrpc:method name="sum" />
  <xrpc:method name="hello" />
</xrpc:api>
  • Now go into estudio and create a new class MY_XMLRPC_API:
class
	MY_XMLRPC_API
 
inherit
	XWA_XRPC_API
 
feature -- Basic operations
 
	hello (a_name: STRING): STRING
                        -- Prints hello.
		require
			a_name_attached: attached a_name
			not_a_name_is_empty: not a_name.is_empty
		do
			Result := "Hello there " + a_name
		end
 
	sum (a_i, a_j: NATURAL_16): INTEGER
			-- Returns the sum of a_i and a_j
		do
			Result := (a_i + a_j).as_integer_32
		end
end
  • Run the server and browse to http://localhost:55000/yourwebapp/demo.xrpc. After the webapp has been translated, compiled and run you should see a page saying invalid method. This is because you tried to make an xml-rpc call with a GET request. Only POST is allowed, though.
  • To make an actual xml-rpc call you can use python. Run:
>>> import xmlrpclib
>>> s=xmlrpclib.ServerProxy("http://localhost:55000/yourwebapp/demo.xrpc")
>>> s.demo.sum(4,5)
>>> s.demo.hello("Gerhard")
