[erlang-questions] Troubleshooting using YAWS + SOAP

[Willem de Jong]

Hi Laura,

I haven't been able to solve your problem, sorry.

I created a very simple server and client that use your WSDL, and it works.
I am copying them below.

One thing that may be the cause of the problem is that one important
statement is still missing in the documentation: you have to actually start
the server... "yaws:start_embedded(Docroot, SL,GL)", assuming that Docroot,
GL and SL have the right values, see http://yaws.hyber.org/soap_intro.yaws.
However, from your error message I don't get the impression that this is
your problem.

Good luck,
Willem

A minimal server:

-module(my_soap).
-export([handler/4]).

-record('p:CodigoVO', {anyAttribs, 'etiqueta', 'valor'}).
-record('p:setParte', {anyAttribs, 'param0', 'param1', 'param2', 'param3',
        'param4', 'param5', 'param6'}).
-record('p:setParteResponse', {anyAttribs, 'return'}).

handler(_Header,
        [#'p:setParte'{'param0' = P0}],
        _Action,
        _SessionValue) ->
    {ok, undefined, setParte(P0)}.

setParte(P0) ->
  CodigoVO = #'p:CodigoVO'{'etiqueta' = P0, 'valor' = 1},
  #'p:setParteResponse'{'return' = CodigoVO}.

A minimal client:

-module(client).
-export([run/1]).

-record('p:CodigoVO', {anyAttribs, 'etiqueta', 'valor'}).
-record('p:setParte', {anyAttribs, 'param0', 'param1', 'param2', 'param3',
        'param4', 'param5', 'param6'}).
-record('p:setParteResponse', {anyAttribs, 'return'}).

run(P0) ->
  Wsdl = yaws_soap_lib:initModel("file://Service.wsdl <file://service.wsdl/>
"),
  Request = #'p:setParte'{'param0' = P0,
                          'param1' = "P1",
                          'param2' = "P2",
                          'param3' = "P3",
                          'param4' = "P4",
                          'param5' = "P5",
                          'param6' = "P6"},
  yaws_soap_lib:call(Wsdl, "setParte", [], [Request]).
