Subject [vfs] Problem accessing SFTP (VFS2)
Date Fri, 30 Sep 2011 08:42:57 GMT

I've been trying to access to an SFTP server to download a 500MB file 
using VFS v1 and I'm always getting a Java heap space error (even after 
increasing the memory for the JVM). Because of that I'm using VFS v2 now 
but at the moment it tries to get the InputStream to start reading the 
file it gets stuck, it's not able to get the InputStream, no matter the 
size of the file, it's getting stucked with big file or very small 
files. If I use version 1 I can get the InputStream but I get the Java 
heap space error, but with version 2 I'm not even able to get the 
As I said, I'm using VFS 2 and jsch 0.1.44.

These are the lines of code:

DefaultFileSystemManager manager = new StandardFileSystemManager();
FileSystemOptions options = new FileSystemOptions();
SftpFileObject ftpFile = (SftpFileObject) 
manager.resolveFile(getXmlFullPath(fileName), options);
Scanner in = new Scanner(new InputStreamReader(ftpFile.getInputStream(), 

It gets stuck in the last line.

Thank you very much.

Kind regards,

Francisco Serrano.
