FileStreaming with SFTP object

Question

Do you have an example that will be able to stream a file? What I am trying to do is to PGP encrypt a file that your api is reading. The file can get in upwards of 300 megs and I do not want to read all of that into memory.

Thanks,

Answer 1

public void get(OutputStream destStream, String remoteFile)

That gets the file's contents to the supplied OutputStream.

Answer 2

Answer 3

John,

I am trying to do something similar, using BouncyCastle to do PGP encryption, and EDT for FTP stuff. Each is a separate Web Service deployed on the same server in Tomcat. Whenever I run the PGP Web Service, subsequent runs of my FTP Web Service fail with java.lang.reflect.InvocationTargetException. I have to restart Tomcat in order to run any FTP jobs after a PGP job. It would seem that the classpath is becoming corrupted somehow.

Have you run into this? Any ideas?

Thanks

If you also add the provider to the java.security file under /jre/lib/security and add the bouncycastle provider jar to the \jre\lib\ext directory, this should solve your re-activation problem. What this does it is loaded the bouncycastle provider into memory. So in your code, you don
