While trying to run this code,

public Session buildSSHConnection() throws Exception{



    String user = "user";

    int port = 22;

    Session session = null;

    try {

        JSch jsch = new JSch();

        jsch.addIdentity(this.getClass().getResource("beispiel.key").getFile());

        session = jsch.getSession(user, host, port);

        session.setConfig("StrictHostKeyChecking", "no");

    }catch(JSchException e) {

            session = null;

            throw e;

    }

    return session;

}    

in my runnable jar file, I always get a FileNotFoundException.

I know the file beispiel.key exists in my jar file, as I checked via

jar -tf ssh.jar 

The Stacktrace is

com.jcraft.jsch.JSchException: java.io.FileNotFoundException: file:/home/sebastian/Schreibtisch/ssh.jar!/beispiel.key (Datei oder Verzeichnis nicht gefunden)

I found a working alternative for my code:

JSch jsch = new JSch();

InputStream in = this.getClass().getResourceAsStream("beispiel.key");

byte c = new byte[in.available()];

in.read(c);

jsch.addIdentity("rsa", c, null, null);

Accessing the file as a Stream works. I didn't try that first because I had a problem finding out the size for my byte array.

Try to set the package name where the file is located in this line:

jsch.addIdentity(this.getClass().getResource("THE_PACKAGE_NAMEbeispiel.key").getFile());

If don't works, try to set a slash before the package name, like:

jsch.addIdentity(this.getClass().getResource("THE_PACKAGE_NAMEbeispiel.key").getFile());
