java - Apache Mina and JSch can't set home dir -

i'm trying write unit test using apache mina , jsch , i'm hitting problem i'm sure has way i've set filesystem on mina.

here the mina setup code:

sshd = sshserver.setupdefaultserver(); sshd.setport(8002);  sshd.setfilesystemfactory(new nativefilesystemfactory() {   @override   public void setcreatehome(boolean createhome)   {     super.setcreatehome(true);   }   @override   public filesystemview createfilesystemview(final session session) {      string username = session.getusername();     // create home if not exist     string homedirstr = "/home/testusr";                         file homedir = new file(homedirstr);      if ((!homedir.exists()) && (!homedir.mkdirs())) {       system.out.println("cannot create user home :: " + homedirstr);     }      return new nativefilesystemview(session.getusername(), false) {       @override       public string getvirtualuserdir() {                 return "/home/testusr";               }     };   }; });  sshd.setsubsystemfactories(arrays.<namedfactory<command>>aslist(new sftpsubsystem.factory())); sshd.setcommandfactory(new scpcommandfactory()); sshd.setkeypairprovider(new simplegeneratorhostkeyprovider("hostkey.ser")); list<namedfactory<userauth>> userauthfactories = new arraylist<namedfactory<userauth>>();     userauthfactories.add(new userauthnone.factory());     sshd.setuserauthfactories(userauthfactories); sshd.setpublickeyauthenticator(new publickeyauthenticator() {     public boolean authenticate(string username, publickey key, serversession session) {            return true;        } }); sshd.start(); 

jsch code:

jsch jsch = new jsch();  string apppublickey = "c:\\conf\\test_private"; jsch.addidentity(new file(apppublickey).getabsolutepath());  com.jcraft.jsch.session session = jsch.getsession("testusr","localhost", 8002); session.setconfig("stricthostkeychecking", "no"); session.settimeout(30000); session.connect(); channel channel = session.openchannel("sftp"); channel.connect(); channelsftp sftpchannel = (channelsftp) channel;  string filename = "c:\\temp\\test.tar.gz"; file f = new file(filename); sftpchannel.put(new fileinputstream(f), "/home/testusr"); 

exception:

i can't seem find examples of creating filesystemview. hoping can me out, i've been stuck on days!

thanks in advance.

this how ended setting jsch & mina in unit test:
