VFS access SFTP with special character password

Learn WSO2 ESB VFS Transport
https://docs.wso2.com/display/ESB481/VFS+Transport

When we need to access the FTP server using SFTP, VFS connection-specific URL need to be given as :

<parameter name="transport.vfs.FileURI">vfs:sftp://username:p@ssword@ftp.server.com/filePath?vfs.passive=true</parameter>

When the password contains a special characters (eg: p@ssword), it gives the following error.

2015-03-27 13:06:03,766 [-] [PassThroughMessageProcessor-5] ERROR VFSTransportSender cannot resolve replyFile
org.apache.commons.vfs2.FileSystemException: Invalid absolute URI "sftp://username:***@ftp.server.com/filePath?vfs.passive=true".

Solution 1:

Replace the special characters with the respective hex representation.

<parameter name="transport.vfs.FileURI">vfs:sftp://username:p%40ssword@ftp.server.com/filePath?vfs.passive=true</parameter>


    Char     Hex Code
    -------  --------
    [space]    %20
       "       %22
       #       %23
       $       %24
       %       %25
       &       %26
       '       %27
       (       %28
       )       %29
       *       %2A
       +       %2B
       ,       %2C
       -       %2D
       .       %2E
       /       %2F
       :       %3A
       ;       %3B
       <       %3C
       =       %3D
       >       %3E
       ?       %3F
       @       %40
       \       %5C
       ^       %5E
       `       %60
       |       %7C

Solution 2:

Change the password to plain text password without any special characters :)
