Hi Phillip, oops, forgot to point out that there are quite a few Java solutions that allow you to use sftp. Using BSF4ooRexx allows you to use them with pure ooRexx, no need to code in Java yourself.
E.g. one solution uses <http://commons.apache.org/proper/commons-vfs/> (can be used from Java 1.5 on), so you would have to download that jar-file (jar="Java archive", a zip container of Java classes and sometimes with resources) and put its path into the environment variable named "CLASSPATH". Once on the CLASSPATH BSF4ooRexx can find all Java classes in that jar file and use them as if they were ooRexx classes. [The documentation for the Apache commons-vfs can be found here: <http://commons.apache.org/proper/commons-vfs/apidocs/index.html>.] The mentioned solution (uploading, downloading, deleting files using sftp) can be found here: <http://www.mysamplecode.com/2013/06/sftp-apache-commons-file-download.html>, so just read that page. Here is a transcription from the shown Java code to ooRexx (untested). Java-code for uploading a file via sftp: // Upload file to remote server using SFTP package com.as400samplecode; import java.io.File; import java.io.FileInputStream; import java.util.Properties; import org.apache.commons.vfs2.FileObject; import org.apache.commons.vfs2.FileSystemOptions; import org.apache.commons.vfs2.Selectors; import org.apache.commons.vfs2.impl.StandardFileSystemManager; import org.apache.commons.vfs2.provider.sftp.SftpFileSystemConfigBuilder; public class SendMyFiles { static Properties props; public static void main(String[] args) { SendMyFiles sendMyFiles = new SendMyFiles(); if (args.length < 1) { System.err.println("Usage: java " + sendMyFiles.getClass().getName()+ " Properties_file File_To_FTP "); System.exit(1); } String propertiesFile = args[0].trim(); String fileToFTP = args[1].trim(); sendMyFiles.startFTP(propertiesFile, fileToFTP); } public boolean startFTP(String propertiesFilename, String fileToFTP){ props = new Properties(); StandardFileSystemManager manager = new StandardFileSystemManager(); try { props.load(new FileInputStream("properties/" + propertiesFilename)); String serverAddress = props.getProperty("serverAddress").trim(); String userId = props.getProperty("userId").trim(); String password = props.getProperty("password").trim(); String remoteDirectory = props.getProperty("remoteDirectory").trim(); String localDirectory = props.getProperty("localDirectory").trim(); //check if the file exists String filepath = localDirectory + fileToFTP; File file = new File(filepath); if (!file.exists()) throw new RuntimeException("Error. Local file not found"); //Initializes the file manager manager.init(); //Setup our SFTP configuration FileSystemOptions opts = new FileSystemOptions(); SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking( opts, "no"); SftpFileSystemConfigBuilder.getInstance().setUserDirIsRoot(opts, true); SftpFileSystemConfigBuilder.getInstance().setTimeout(opts, 10000); //Create the SFTP URI using the host name, userid, password, remote path and file name String sftpUri = "sftp://"; + userId + ":" + password + "@" + serverAddress + "/" + remoteDirectory + fileToFTP; // Create local file object FileObject localFile = manager.resolveFile(file.getAbsolutePath()); // Create remote file object FileObject remoteFile = manager.resolveFile(sftpUri, opts); // Copy local file to sftp server remoteFile.copyFrom(localFile, Selectors.SELECT_SELF); System.out.println("File upload successful"); } catch (Exception ex) { ex.printStackTrace(); return false; } finally { manager.close(); } return true; } } The ooRexx transcription (untested) could look like this: -- Upload file to remote server using SFTP -- "main" method in a Java class can be used as the (prolog) Rexx code parse arg propertiesFile fileToFtp res=startFtp(propertiesFile, fileToFtp~strip) say "startFtp() returned:" res "(0=.false, 1=.true=success)" ::routine startFTP use arg propertiesFilename, fileToFTP props = .BSF~new("java.util.Properties") manager = .BSF~new("org.apache.commons.vfs2.impl.StandardFileSystemManager") -- no need to try and catch, if there is an error, the Rexx interpreter will abort -- and give the respective Java exception information props~load(.bsf~new("java.io.FileInputStream", "properties/"propertiesFilename)) serverAddress = props~getProperty("serverAddress" )~strip userID = props~getProperty("userId" )~strip password = props~getProperty("password" )~strip remoteDirectory = props~getProperty("remoteDirectory")~strip localDirectory = props~getProperty("localDirectory" )~strip -- check if the file exists filepath = localDirectory || fileToFTP file = .bsf~new("java.io.File", filepath) if \file~exists then raise syntax 90.900 array ("Error.
