Laut: http://www.datanoise.com/articles/2008/7/2/actionwebservice-is-back sollte man den ActionWebService nutzen können.

Leider kann beim Aufruf von WSDL folgendes passieren:

NameError (uninitialized constant SOAP::XSDNamespaceTag):

ActionView::MissingTemplate (Missing template caller/wsdl.erb in view path app/views):

Das Problem besteht schon einige Zeit, wie das folgende Ticket zeigt: http://dev.ctor.org/soap4r/ticket/476

Die Lösung unter diesem Ticket ist von Simon. Da er leider nicht “unterschrieben” hat, hier nochmal einen “herzlichen Dank” dafür.

In der Datei environment.rb einfach folgendes eintragen:

module SOAP

 SOAPNamespaceTag = 'env'

 XSDNamespaceTag = 'xsd'

 XSINamespaceTag = 'xsi'

end
