Re: Using Apache VFS to FTP to the AS/400 IFS

["Sarah Poger Gladstone" <listmember@xxxxxxxxxxxxxx>]

Bill-

Below is a Java class with a main method that I am using for testing
an FTP upload using the VFS APIs.

import org.apache.commons.vfs.FileObject;
import org.apache.commons.vfs.FileSelector;
import org.apache.commons.vfs.FileSystemManager;
import org.apache.commons.vfs.FileSystemOptions;
import org.apache.commons.vfs.Selectors;
import org.apache.commons.vfs.VFS;
import org.apache.commons.vfs.impl.DefaultFileSystemManager;
import org.apache.commons.vfs.provider.ftp.FtpFileSystemConfigBuilder;

public class Ftptest1 {

	
	
	
	public Ftptest1() {
    //	obtain a FileSystemManager instance
		FileSystemManager mgr = null;
		try {
			mgr = VFS.getManager();
			
			FileSystemOptions fileSystemOptions;
			FileSystemOptions opts = new FileSystemOptions();
			fileSystemOptions = opts;

			//fileSystemOptions = opts;
			//SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(fileSystemOptions,
"no");
			//FtpFileSystemConfigBuilder.getInstance().setDataTimeout(opts, 100);
			FtpFileSystemConfigBuilder.getInstance().setUserDirIsRoot(fileSystemOptions,
false);
			//FileSystemConfigBuilder config =
(FileSystemConfigBuilder)FtpFileSystemConfigBuilder.getInstance();
			
			
			
			boolean tmp =
FtpFileSystemConfigBuilder.getInstance().getUserDirIsRoot(fileSystemOptions);
			System.out.println("Setting for 'UserDirIsRoot' :" + tmp);
			//locate the local file by name
			System.out.println("Now locate the local file by name");
			String strLocalFile = "C:\\sgladstone\\edfiles\\" + "datafile";
			FileObject foLocalFile = mgr.resolveFile(strLocalFile);
				 	
//			locate the remote file by name
			System.out.println("Now locate the remote file by name");
			
			String rUrlStr =
"ftp://myuserprofile:mypassword@myas400hostname/home/aplsup/sarahtest.txt";
;
			FileObject foRemoteFile = mgr.resolveFile( rUrlStr, opts);
			
			if(foRemoteFile.exists()){
				System.out.println("Remote file exists");
			}else{
				System.out.println("Remote file does NOT exist");
			}
			

			FileSelector fS = Selectors.SELECT_SELF ;
			

//			 Copy the contents of the local file to the remote file.
//			 ie upload the file to the server
			if (foLocalFile.exists()){	
				System.out.println("local file exists, try copyFrom cmd");
				foRemoteFile.copyFrom(foLocalFile, fS);	
			}else{
				System.out.println("Local file does not exist. Nothing to upload. ");
			}
			
		}catch (Exception e) {
			e.printStackTrace();
		}finally {
			System.out.println("Now close the FileSystemManager");
			if( mgr != null) ((DefaultFileSystemManager) mgr).close();	
		}

	
	}
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		 new Ftptest1();
		 System.out.println("Now exit main");

	}

}
