Coldfusion Standard and Stored Procedure

Hi, I would like to know if Oracle stored procedure are supported in Coldfusion 2016 Standard (exept for reference cursors).

I try to call a simply stored procedure like this:

CREATE OR REPLACE PROCEDURE MYDATABASE.TEST_PROC

( FIRSTNAME IN VARCHAR2,

LASTNAME IN VARCHAR2,

FULLNAME OUT VARCHAR2)

AS

BEGIN

  FULLNAME := FIRSTNAME || '  ' || LASTNAME;

END;

/

With this coldfusion code:

<cfstoredproc procedure="TEST_PROC" datasource="mydatasource" returncode="No">

   <cfprocparam type="In" cfsqltype="CF_SQL_VARCHAR" dbvarname=":FIRSTNAME" value="John">

  <cfprocparam type="In" cfsqltype="CF_SQL_VARCHAR" dbvarname=":LASTNAME" value="Doe">

  <cfprocparam type="Out" cfsqltype="CF_SQL_VARCHAR" dbvarname=":FULLNAME" variable="fullname">

</cfstoredproc>

But I receive this error:

ErrorCode 17041

Message Missing IN or OUT parameter at index:: 4

Anyone can help me?
