vfs sftp fails restablishing the connection after sftp server restart service

[José Luis Núñez <jo...@compuarte.net.mx>]

I am developing an application for monitoring a local folder, when a file
was changed or added this is transfered to another box via sftp or ftp

Monitoring routines of vfs works fine, ftp also, sftp while the other box is
alive has not problem, but if the other box is down when monitor trigger the
event after remote box is restablished all subsecuent transfers abort with
error.

If instead of sftp we did the same process with ftp, vfs restablish the
connection succesfuly


Any idea?


 
SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(opts,"no"
);
            SftpFileSystemConfigBuilder.getInstance().setTimeout(opts,1000);
            manager = VFS.getManager();

		quearchivo = fileobject.getURL().toString();

		fileobject = manager.resolveFile(fileobjectStringURL,opts);

		if (fileobject.exists()){  <--- Here throws error
		...

Thanks a lot, the problem was that my try sequence was wrong

I had

try{	...
	} catch (FileSystemException e){
	...
	} catch (IOException e) {
	...
	}

When the system lose sftp connection first catch the FileSystemException but
the critical exception really was IOException, everything works fine after
reorder the sequence

try{	...
	} catch (IOException e) {
	...
	} catch (FileSystemException e){
	...
	}

Hmmm .... looks like there is no reestablishing connection stuff in sftp
- or its broken.
Please open a jira ticket at http://issues.apache.org/jira, I'll have a look
at it then, though, might take some time as I am on vacation for the next
couple of days :-)

Thanks!
Ciao,
Mario
