This *is* a hosts key problem - see error trace below: org.apache.commons.vfs.FileSystemException: Could not connect to SFTP server at "sftp://test:[EMAIL PROTECTED]/". at org.apache.commons.vfs.provider.sftp.SftpFileProvider.doCreateFileSystem (SftpFileProvider.java:87) at org.apache.commons.vfs.provider.AbstractOriginatingFileProvider.findFile (AbstractOriginatingFileProvider.java:76) at org.apache.commons.vfs.provider.AbstractOriginatingFileProvider.findFile (AbstractOriginatingFileProvider.java:61) at org.apache.commons.vfs.impl.DefaultFileSystemManager.resolveFile(Default FileSystemManager.java:524) at org.apache.commons.vfs.impl.DefaultFileSystemManager.resolveFile(Default FileSystemManager.java:488) at org.apache.commons.vfs.impl.DefaultFileSystemManager.resolveFile(Default FileSystemManager.java:458) at testSFTP.main(testSFTP.java:10) Caused by: org.apache.commons.vfs.FileSystemException: Could not connect to SFTP server at "localhost". at org.apache.commons.vfs.provider.sftp.SftpClientFactory.createConnection( SftpClientFactory.java:172) at org.apache.commons.vfs.provider.sftp.SftpFileProvider.doCreateFileSystem (SftpFileProvider.java:79) ... 6 more Caused by: com.jcraft.jsch.JSchException: UnknownHostKey: localhost.
