[JSch-users] sftp from servlet

[Jiang, P. <Pei...@nr...>]

I can run the following section of code from command line. But when I ran it from a web application (tomcat), I got NullPointerException.

java.lang.NullPointerException
com.jcraft.jsch.jce.DH.getE(Unknown Source)
com.jcraft.jsch.DHG1.init(Unknown Source)
com.jcraft.jsch.Session.receive_kexinit(Unknown Source)
com.jcraft.jsch.Session.connect(Unknown Source)
com.jcraft.jsch.Session.connect(Unknown Source)

Please help!

try {
      JSch jsch = new JSch();
    	Session session = jsch.getSession(username, hostname, port);

    	UserInfo ui = new JSchUserInfo(password);
    	session.setUserInfo(ui);

    	session.connect();

    	Channel channel = session.openChannel("sftp");
    	channel.connect();
    	ChannelSftp c = (ChannelSftp) channel;

	//copy file
	//test only
	Vector list = c.ls(".");
	logger.info(list.toString());

	c.exit();
	session.disconnect();
} catch (Exception e) {
