HELP! : Newbie Problems with JSCH

[Philippe Desrosiers]

I'm trying to use using JSCH to upload some files via SFTP. Whenever I try to call the Session.Connect() method, I receive the following exception:

com.jcraft.jsch.JSchException: Auth cancel
at com.jcraft.jsch.Session.connect(Unknown Source)
at com.jcraft.jsch.Session.connect(Unknown Source)
at com.mypackage.MySuperClass.executeInternal(SFTPPushCommand.java:68)

at java.lang.Thread.run(Thread.java:595)

Here's the basic code I'm using:

Session session = jsch.getSession("myUserName", "mySFTPHostName", 22);
        UserInfo ui = new MyUserInfo();
        session.setUserInfo(ui);    //at this point, application asks, via MyUserInfo, if I want to connect to an unverified server IP, or whatever, I respond "yes".
        session.connect();    //at this point, I receive the Exception mentioned above

I'm not using any complicated public/private key authentication or anything, and command-line SFTP seems to work fine. Can anyone help me out with this?

After further investigation, it looks like the target SFTP server is specifying authentication methods "publickey,gssapi-with-mic,password". I don't really know what this means. Do I need to set up some sort of public key? How do I do this?
