handling hard SFTP errors

[sayeed]

Hi,

I am evaluating Jscape SFTP component for a web application and facing this problem.

Using Jscape, when I am in the middle of an SFTP activity and cause a network error (pull the LAN cable or disable the NIC), the thread throws an error and just hangs.

I need to restart the JVM in order to recover from this issue. How can I handle this issue and recover from such hard errors?

It appears the remote host terminated the connection prematurely.

[sayeed]

True, but how do we ensure such exceptions are gracefully handled by Jscape? The remote server is not in our control...

[mjawwad]

You can catch the exception using try-catch blocks and handle the that case in your application.

try
{
}
catch (Exception e)
{
// do something here
}

I am assuming you are using either Secure iNet Factory or Secure FTP Factory for Java
