Remote Shell Scripts need to export the ENV variable again.

public class JavaRemoteRunShell {

private Connection conn;

private String ipAddr;

private String charset = Charset.defaultCharset().toString();

private String userName;

private String password;

public JavaRemoteRunShell(String ipAddr, String userName, String password, String charset) {

this.ipAddr = ipAddr;

this.userName = userName;

this.password = password;

if(charset != null) {

this.charset = charset;

}

}

public boolean login() throws IOException {

conn = new Connection(ipAddr);

conn.connect(); //

return conn.authenticateWithPassword(userName, password); //

}

public String exec(String cmds) {

InputStream in = null;

String result = "";

try {

if (this.login()) {

Session session = conn.openSession(); // open one session

session.execCommand(cmds);

in = session.getStdout();

result = this.processStdout(in, this.charset);

System.out.println(result);

System.out.println("ExitCode: " + session.getExitStatus());

session.close();

conn.close();

}

} catch (IOException e1) {

e1.printStackTrace();

}

return result;

}

public String processStdout(InputStream in, String charset) {

byte[] buf = new byte[1024];

StringBuffer sb = new StringBuffer();

try {

while (in.read(buf) != -1) {

sb.append(new String(buf, charset));

}

} catch (IOException e) {

e.printStackTrace();

}

return sb.toString();

}

public static void lsViaSSH(String hostname, String username, String password) throws Exception {

Connection conn = new Connection(hostname);

conn.connect();

boolean isAuthenticated = conn.authenticateWithPassword(username, password);

System.out.println(isAuthenticated);

if (isAuthenticated = true){

Session sess = conn.openSession();

sess.execCommand("sh test.sh " );

InputStream stdout = new StreamGobbler(sess.getStdout());

sess.close();

conn.close();

}

}

public static void main(String[] args ) throws Exception{

String ipAddr = "127.0.0.1";

JavaRemoteRunShell c = new JavaRemoteRunShell( ipAddr,? userName,? password,? charset);
