[Lazarus] Web-services

[michael.vancanneyt at wisa.be]

Hi,

In the generated hello.pas, try changing  'literal' to 'document' in the
following calls:

   mm.SetOperationCustomData(
     sUNIT_NAME,
     'HelloWorldPortType',
     'hello',
     'FORMAT_Input_EncodingStyle',
     'literal'
   );
   mm.SetOperationCustomData(
     sUNIT_NAME,
     'HelloWorldPortType',
     'hello',
     'FORMAT_OutputEncodingStyle',
     'literal'
   );

Michael.
