NOTE: The following code is now available as a sample Job named FileTransferPolling in JAMS V7.3 or higher. You can find this Job by clicking the Definitions shortcut and selecting the Samples folder. 

  # This job will poll a remote server for specific files based on the filemask
  provided and report how many files are available for processing
  # This job can be used as a precheck job for an FTP Job
  # When the files are found the script will increase the counter and list how
  many files were found that match the FileMask specified. 
  # NOTE: The Parameters found in the options would need to exist as parameters
  in the FTP job or listed as Variables 
 
  # [Options]
  #
  ## FileMask parameter is a pattern of characters and wildcards used to match
  folder and filenames ( *123.txt, 123*abc.txt)
  Write-Host "Filemask: " <<filemask>> 

  # SFTP parameter - Set 0 to Off for standard FTP and set to 1 for SFTP
  Write-Host "SFTP Option: " <<SFTP>>
  
  # PRECHECK parameter would be the number of files to check for
  Write-Host "Expected Count: " <<PRECHECK>>
  
  # FTPCred parameter would be the FTP Credentials
  Write-Host "FTP Cred: " <<FTPCred>>
  
  # FTPPARAMS parameter would be options for Server Binary Port and Timeout options
  Write-Host "Extra FTP Params:" <<FTPPARAMS>>
  
  # FTPHostName paramter would be the host name of the FTP Server
  Write-Host "FTP Host Name:" <<FTPHostName>>
 
   # RemoteSourcePath parameter would be the path of the remote source
  Write-Host "Remote Source Location:" <<REMOTESOURCEPATH>>
  
  # ResubmitSleep parameter would be the time alotted for polling job to sleep
  Write-Host "Sleep Time:" <<RESUBMITSLEEP>>
