Hallo,
thanks.
My code:
Client Proxy
DATA: service TYPE REF TO zpc_co_reset_user_password .
data: lo_sys_exception type ref to cx_ai_system_fault ,
        err_string type string.
  TRY.
      CREATE OBJECT service
        exporting
          logical_port_name = 'DEFAULT'.
    CATCH cx_ai_system_fault .
  ENDTRY.
  DATA: user TYPE zpc_reset_user_passwordinput .
  DATA: out TYPE zpc_reset_user_passwordoutput .
  TRY.
      user-bname = sy-uname.
      CALL METHOD service->zbc_reset_user_password
        EXPORTING
          input  = user
        IMPORTING
          output = out.
      message = out-message.
    catch cx_ai_system_fault into lo_sys_exception.
      err_string = lo_sys_exception->get_text( ).
    CATCH cx_ai_application_fault.
  ENDTRY.
In the WSDL-File
- <wsdl:portType name="ZWS_RESET_SAP_PASSWD">
- <wsdl:operation name="ZbcResetUserPassword">
  <wsdl:input message="tns:ZbcResetUserPassword" />
  <wsdl:output message="tns:ZbcResetUserPasswordResponse" />
  </wsdl:operation>
  </wsdl:portType>
How should i call the operation?
I create the object for the proxy and then i call the proxy method zbc_reset_user_data.
What's wrong?
Regards
