I am trying to automate non-browser based functionality (thick client application - Delphi based), web-based application(new java application) and opted to use Selenium + AutoIt for this. I need to compare data displayed in both applications for one particular user.
To access the thick client application, I need to use Remote Desktop Connection. I was able to connect to the remote desktop through selenium+autoit but not able to send any commands to the remote machine. If anyone is aware of the solution please help.
Following is the code I used.
import java.io.File;
import autoitx4java.AutoItX;
import com.jacob.com.LibraryLoader;
public class sampleTest {
static String rdcPwd = "password";
static String remoteComputerName = "computername";
public static void main(String[] args) throws InterruptedException {
String jacobDllVersionToUse;
jacobDllVersionToUse = "jacob-1.18-x64.dll";
File file = new File("lib", jacobDllVersionToUse);
System.setProperty(LibraryLoader.JACOB_DLL_PATH, file.getAbsolutePath());
AutoItX x = new AutoItX();
x.run("MSTSC.EXE");
x.winActivate("Remote Desktop Connection");
x.winWaitActive("Remote Desktop Connection");
x.controlClick("Remote Desktop Connection", "Co&nnect", "1");
Thread.sleep(15000);
x.send(rdcPwd);
Thread.sleep(3000);
x.controlClick("Windows Security", "", "[CLASS:Button; INSTANCE:2;]");
Thread.sleep(10000);
x.send("#r"); // Not Working
x.run("explorer.exe"); //Not Working
}
}
Thanks,

I want to switch from Jsch to Apache Mina to query remote Linux hosts and to get the few tasks done.
I need to achieve things like list files of a remote host, change directory, get file contents, put a file into the remote host etc.,
I am able to successfully connect and execute a few shell commands using session.executeRemoteCommand().
public byte[] getRemoteFileContent(String argDirectory, String fileName)
throws SftpException, IOException {
ByteArrayOutputStream stdout = new ByteArrayOutputStream();
StringBuilder cmdBuilder = new StringBuilder("cat" + SPACE + remoteHomeDirectory);
cmdBuilder.append(argDirectory);
cmdBuilder.append(fileName);
_session.executeRemoteCommand(cmdBuilder.toString(), stdout, null, null);
return stdout.toByteArray();
}
public void connect()
throws IOException {
_client = SshClient.setUpDefaultClient();
_client.start();
ConnectFuture connectFuture = _client.connect(_username, _host, portNumber);
connectFuture.await();
_session = connectFuture.getSession();
shellChannel = _session.createShellChannel();
_session.addPasswordIdentity(_password);
// TODO : fix timeout
_session.auth().verify(Integer.MAX_VALUE);
_channel.waitFor(ccEvents, 200);
}
I have the following questions,
How can I send a ZIP file to a remote host much easily in API level (not the Shell commands level)? And all other operations in API level.
Can I secure a connection between my localhost and remote through a certificate?
As of now, I am using SSHD-CORE and SSHD-COMMON version 2.2.0. Are these libraries enough or do I need to include any other libraries?
executeRemoteCommand() is stateless how can I maintain a state?
I needed sshd-sftp and its APIs to get the file transfer work.
Below code gets the proper API,
sftpClient = SftpClientFactory.instance().createSftpClient(clientSession);
On sftpClinet I called read() and write() methods get the task done. This answers my question fully.
I have a piece of code which connects to a Unix server and executes commands.
I have been trying with simple commands and they work fine.
I am able to login and get the output of the commands.
I need to run an Ab-initio graph through Java.
I am using the air sandbox run graph command for this.
It runs fine, when I login using SSH client and run the command. I am able to run the graph. However, when I try to run the command through Java it gives me a "air not found" error.
Is there any kind of limit on what kind of Unix commands JSch supports?
Any idea why I'm not able to run the command through my Java code?
Here's the code:
public static void connect(){
try{
JSch jsch=new JSch();
String host="*****";
String user="*****";
String config =
"Host foo\n"+
" User "+user+"\n"+
" Hostname "+host+"\n";
ConfigRepository configRepository =
com.jcraft.jsch.OpenSSHConfig.parse(config);
jsch.setConfigRepository(configRepository);
Session session=jsch.getSession("foo");
String passwd ="*****";
session.setPassword(passwd);
UserInfo ui = new MyUserInfo(){
public boolean promptYesNo(String message){
int foo = 0;
return foo==0;
}
};
session.setUserInfo(ui);
session.connect();
String command="air sandbox run <graph-path>";
Channel channel=session.openChannel("exec");
((ChannelExec)channel).setCommand(command);
channel.setInputStream(null);
((ChannelExec)channel).setErrStream(System.err);
InputStream in=channel.getInputStream();
channel.connect();
byte[] tmp=new byte[1024];
while(true){
while(in.available()>0){
int i=in.read(tmp, 0, 1024);
if(i<0)break;
page_message=new String(tmp, 0, i);
System.out.print(page_message);
}
if(channel.isClosed()){
if(in.available()>0) continue;
System.out.println("exit-status: "+channel.getExitStatus());
break;
}
try{Thread.sleep(1000);}catch(Exception ee){}
}
channel.disconnect();
session.disconnect();
}
catch(Exception e){
System.out.println(e);
}
}
public static void main(String arg[]){
connect();
}
public String return_message(){
String ret_message=page_message;
return ret_message;
}
public static abstract class MyUserInfo
implements UserInfo, UIKeyboardInteractive{
public String getPassword(){ return null; }
public boolean promptYesNo(String str){ return false; }
public String getPassphrase(){ return null; }
public boolean promptPassphrase(String message){ return false; }
public boolean promptPassword(String message){ return false; }
public void showMessage(String message){ }
public String[] promptKeyboardInteractive(String destination,
String name,
String instruction,
String[] prompt,
boolean[] echo){
return null;
}
}
The "exec" channel in the JSch (rightfully) does not allocate a pseudo terminal (PTY) for the session. As a consequence a different set of startup scripts is (might be) sourced (particularly for non-interactive sessions, .bash_profile is not sourced). And/or different branches in the scripts are taken, based on absence/presence of the TERM environment variable. So the environment might differ from the interactive session, you use with your SSH client.
So, in your case, the PATH is probably set differently; and consequently the air executable cannot be found.
To verify that this is the root cause, disable the pseudo terminal allocation in your SSH client. For example in PuTTY, it's Connection > SSH > TTY > Don't allocate a pseudo terminal. Then, go to Connection > SSH > Remote command and enter your air ... command. Check Session > Close window on exit > Never and open the session. You should get the same "air not found" error.
Ways to fix this, in preference order:
Fix the command not to rely on a specific environment. Use a full path to air in the command. E.g.:
/bin/air sandbox run <graph-path>
If you do not know the full path, on common *nix systems, you can use which air command in your interactive SSH session.
Fix your startup scripts to set the PATH the same for both interactive and non-interactive sessions.
Try running the script explicitly via login shell (use --login switch with common *nix shells):
bash --login -c "air sandbox run sandbox run <graph-path>"
If the command itself relies on a specific environment setup and you cannot fix the startup scripts, you can change the environment in the command itself. Syntax for that depends on the remote system and/or the shell. In common *nix systems, this works:
String command="PATH=\"$PATH;/path/to/air\" && air sandbox run <graph-path>";
Another (not recommended) approach is to force the pseudo terminal allocation for the "exec" channel using the .setPty method:
Channel channel = session.openChannel("exec");
((ChannelExec)channel).setPty(true);
Using the pseudo terminal to automate a command execution can bring you nasty side effects. See for example Is there a simple way to get rid of junk values that come when you SSH using Python's Paramiko library and fetch output from CLI of a remote machine?
For a similar issues, see
Certain Unix commands fail with "... not found", when executed through Java using JSch even with setPty enabled
Commands executed using JSch behaves differently than in SSH terminal (bypasses confirm prompt message of "yes/"no")
JSch: Is there a way to expose user environment variables to "exec" channel?
Command (.4gl) executed with SSH.NET SshClient.RunCommand fails with "No such file or directory"
you could try to find out where "air" resides with
whereis air
and then use this outcome.
something like
/usr/bin/air sandbox run graph
You can use an ~/.ssh/environment file to set your AB_HOME and PATH variables.
I wrote a 2013/2016 VSTO app for Microsoft Word using C#. My app creates a new toolbar with buttons. One such button runs my app, which launches a basic Windows Form.
Before the user can work with my app, they need to enter information like their license code and email address. My code in turns sends a basic request to my licensing server and awaits a response.
All my code has been running just fine and now it no longer is. Now, when I run the code, I receive the following two error messages:
System.Net.WebException: 'The underlying connection was closed: An
unexpected error occurred on a send.' Inner Exception: IOException:
Unable to read data from the transport connection: An existing
connection was forcibly closed by the remote host.
and
System.Net.WebException: 'The underlying connection was closed: An
unexpected error occurred on a send.' Inner Exception:
SocketException: An existing connection was forcibly closed by the
remote host
I decided to run the code using a standard console app to see if I received the same error message, and sure enough, it worked great! Now I am wondering if Word or the Microsoft VSTO technology is blocking my app from accessing my server.
Here is the code in VSTO that does not work
Note 1: Created a basic 2013/2016 C# VSTO add-in, added a toolbar, and added
Note 2: Added a reference to System.Web.
Note 3: Modified the website link and the query strings as I did not want to publish them on this public forum.
using System;
using Microsoft.Office.Tools.Ribbon;
using System.Web;
using System.Net;
namespace WordAddIn3
{
public partial class Ribbon1
{
private void Ribbon1_Load(object sender, RibbonUIEventArgs e)
{
}
private void button1_Click(object sender, RibbonControlEventArgs e)
{
// Attempt to activate the product using the licensing server on the website.
Console.WriteLine("** ActivateLicense");
//build the url to call the website's software licensing component.
var builder = new UriBuilder("https://validwebsite.com");
builder.Port = -1;
//build the query string.
var query = HttpUtility.ParseQueryString(builder.Query);
query["license_key"] = "validactivationcdode";
query["product_id"] = "validproductid";
query["email"] = "validemailaddress";
builder.Query = query.ToString();
string url = builder.ToString();
Console.WriteLine("activation request:");
Console.WriteLine(url); //display the REST endpoint.
//make the synchronous call to the web service.
var syncClient = new WebClient();
var responseStream = syncClient.DownloadString(url);
Console.WriteLine("Response stream:");
Console.WriteLine(responseStream); //display the server json response.
}
}
}
Here is what is pretty much the same exact code in a console app that does work
Note 1: Created a basic C# console app.
Note 2: Added a reference to System.Web.
Note 3: Modified the website link and the query strings as I did not want to publish them on this public forum. You will receive an error, but that is due to the sample website not having a licensing server.
using System;
using System.Net;
using System.Web;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
// Attempt to activate the product using the licensing server on the website.
Console.WriteLine("** ActivateLicense");
//build the url to call the website's software licensing component.
var builder = new UriBuilder("https://validwebsite.com");
builder.Port = -1;
//build the query string.
var query = HttpUtility.ParseQueryString(builder.Query);
query["license_key"] = "validactivationcdode";
query["product_id"] = "validproductid";
query["email"] = "validemailaddress";
builder.Query = query.ToString();
string url = builder.ToString();
Console.WriteLine("activation request:");
Console.WriteLine(url); //display the REST endpoint.
//make the synchronous call to the web service.
var syncClient = new WebClient();
var responseStream = syncClient.DownloadString(url);
Console.WriteLine("Response stream:");
Console.WriteLine(responseStream); //display the server json response.
Console.ReadKey();
}
}
}
Can you help me determine why the code is no longer working in the add-in where it did before (with no code changes)?
I read a lot online and there seem to be too many reasons why this might happen. As an FYI, the website with the licensing server is running. It is (and always has been) a little slow, but when running the code with VSTO, the response is immediate (suggesting no timeout). The Console code runs and there is never a timeout.. I always get a response from the licensing server.
On another thread for a similar problem, someone recommended running WireShark. I am not really familiar with the product, but during my working console run, I received no error messages and instead I got messages like these:
Standard query 0x626a AAAA mywebsite.com
and
Standard query response 0x626a AAAA mywebsite.com
However, if I run the same code in VSTO, I get additional messages that are errors (this one shows up twice):
TCP 60 443 → 50308 [RST, ACK] Seq=1 Ack=125 Win=32768 Len=0
I'm developing an application in which much of the work interacts with aws S3.
Initial situation:
Domino: Release 9.0.1FP6.
Application on xpages with aws utilities working perfectly with the typical functionalities of readBucket, downloadFile, createBucket etc.
For application needs, due to its weight, I need to separate the logic of the same and try three methods for their separation.
In another database, an agent receives a docID from the main application and executes the order of the requested operations for S3. The mechanism works perfectly, but the memory consumption is unacceptable so it is discarded.
In another new database with the same libraries and classes needed to focus with XAgent based on How to schedule an Xagent from a Domino Java agent? Agent but with the access not ssl that points Per Henrik Lausten. It works fine, but if we load s3 it gives errors.
Console Java:
Starting http://localhost/proves\s3.nsf/demo.xsp
java.lang.NullPointerException --> at sun.net.www.http.HttpClient.parseHTTPHeader(HttpClient.java:727)
Console Domino
HTTP JVM: demo.xsp --> beforePageLoad ---> Hello Word
HTTP JVM: CLFAD0211E: Exception thrown. please consult error-log-0.xml
Error-log-0.xml
Exception occurred servicing request for: /proves/s3.nsf/demo.xsp - HTTP Code: 500
IBM_TECHNICAL_SUPPORT\ xpages_exc.log
java.lang.NoClassDefFoundError: com.amazonaws.auth.AWSCredentials
I think the problem may be in using this mechanism because it is not secure, if it is accessed from the browser to demo.xsp it will be running the entire load of aws xon the default credentials.
I test with another SSL-based xagent according to Devin Olson's blog post, Scheduled Xagents, but throw error:
Console Java:
Exception:javax.net.ssl.SSLHandshakeException: com.ibm.jsse2.util.j: No trusted certificate found
Is the separation approach of the logic of the application correct?
Any suggestions as to why the third procedure for SSL is failing?
Thanks in advance

Although the two bd's reside on the same server, I have an SSL Certificate Authority in the JVM in case this is the fault, but it still gives the same error. SSLHandshakeException: com.ibm.jsse2.util.j: No trusted certificate.

I'm using Sap Jco to connect to SAP database with the front end being Java(JSF), When I connect to SAP with:
try {
mConnection =JCO.createClient("400", // SAP client
"c3026902", // userid
"********", // password
"EN", // language
"iwdf5020", // host name
"00"); // system number
mConnection.connect();
}
catch (Exception ex) {
ex.printStackTrace();
System.exit(1);
}
Problem I'm facing is when run the application for the first time, data is displayed but when I re-run it says "Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC' "
Can any one help me in resolving the issue?????
This sounds like the API cannot load the native driver files.
The SAP Java Connector consists of a native runtime part, that does the actuall communication and a Java API that wraps this functionality with a java api.
The Java API is inside the sapjco.jar and the native drivers are e.g on windows inside librfc32.dll and sapjcorfc.dll.
Place these dll's into your system path (e.g. windows: C:\WiNDOWS\system32) and it should run.
Cheers
Sebastian
Are your DLLs located in the Windows system32 folder? If so, are you probably using the wrong architecture? (x64 DLL on 32 bit or vice versa)
Also, are the DLLs the same version as the java api? If you have SAP GUI installed there could be older DLLs around.
Defining SAP connection:
For the Version 3,0 of the sapjco library there exists plenty of useful information. To create a connection following the instructions in:
http://www.browseye.com/linkShare.html?url=http://help.sap.com/saphelp_nwpi711/helpdata/en/46/fb807cc7b46c30e10000000a1553f7/content.htm?bwsCriterion=%22Setting%20Up%20Connection%22&bwsMatch=1&bwsCriterion=%22Setting%20Up%20Connection%22&bwsMatch=1
There are a few thing that you should take into account:
Place the dll file in the same place that the jar.
The dll must be the right version for your operating system and architecture otherwise you will get a native library error.

}
}
In SAPJco 3.0 connections are build from the info contained in a “Destination”.
The documentation example use a properties file to save the “Destination”. However it is a non-secure way to keep connection info. As is indicated on the documentation in the hightlighted paragraph you can see on next link.
http://help.sap.com/saphelp_nwpi711/helpdata/en/48/5fb9f9b523501ee10000000a421937/content.htm?bwsCriterion=%22In%20practice%20you%20should%20avoid%20this%20for%20security%20reasons.%22&bwsMatch=1
You can keep connection info on a database or any other storage system if you create a custom “DestinationDataProvider” In the Examples provided with the SAPJco library there is an example of how to create a custom DestinationDataProvider.
