Try the following code. It will work for you.

System.setProperty("webdriver.chrome.driver","D:\\Selenium\\chromedriver_win32\\chromedriver.exe");
driver = new ChromeDriver();
driver.get("http://toolsqa.com/selenium-webdriver/install-testng/");

Thread.sleep(5000);
List<WebElement> wb = driver.findElements(By.tagName("a"));
ListIterator<WebElement> lt = wb.listIterator();
System.out.println(wb.size());
Thread.sleep(5000);
for(WebElement x:wb) {
String linkName= x.getText();
System.out.println(linkName);
if(linkName.contains("HOME")) {
Thread.sleep(5000);
x.click();
break;
}else {
System.out.println("Link does not contain HOME");

In the program.cs the user is asked if he wanna read the data, if he types y then the method Doc.ReadDoc starts is there any proper way:
class Program
{
static void Main(string[] args)
{
do
{
var path = "C:\\Users\\ks\\Desktop\\C#";
string fileName = path + #"\TestFile.txt";
Console.WriteLine("Do you want to read it? y/n");
string yesorno = Console.ReadLine();
if (yesorno=="y")
{
Console.Clear();
Doc.ReadDoc();
}
Console.WriteLine("Which type of vehicle");
string type = Console.ReadLine();
Console.WriteLine("how many tires");
int raeder = Convert.ToInt32( Console.ReadLine());
var Vehicle = new Used_Cars(type, raeder);
Doc.Write(Vehicle);
} while (true);
}
}
The Class with the methods (Read, Write):
public static List<string> ReadDoc()
{
var list = new List<string>();
var pfad = "C:\\Users\\ks\\Desktop\\C#";
string fileName = path+ #"\TestFile.txt";
try
{
using (StreamReader sr = new StreamReader(fileName))
{
Console.WriteLine("Data found");
string line;
Console.WriteLine(sr.ReadToEnd());
}
}
catch (Exception e)
{
// Let the user know what went wrong.
Console.WriteLine("Data not found");
Console.WriteLine(e.Message);
list = null;
}
return list;
}
And the last Method is the Write method, is this a good code to save properties in a file? How could i stop the program with ESC or smth like that, so if the user presses ESC it should stop.
public static void Write(Used_Cars vehicle)
{
var pfad = "C:\\Users\\ks\\Desktop\\C#";
string fileName = path+ #"\TestFile.txt";
Console.WriteLine("Is it correct?");
Console.WriteLine("y/n");
string yeahorno= Console.ReadLine();
if (jaodernein == "y")
{
try
{
using (StreamWriter writer = new StreamWriter(fileName))
{
writer.WriteLine(vehicle.Vehicle);
writer.WriteLine(vehicle.Wheels);
Console.WriteLine();
}
}
catch (Exception exp)
{
Console.Write(exp.Message);
}
}
}
I have a method which performs some task(reading, writing files and other tasks also) for almost 3 minutes.
I want to bind progress bar in javafx which can run with progress of the method.
This is my method
System.out.println("Going to load contract/security:"+new Date());
Map<Integer,FeedRefData> map = loadContractAndSecurityFromFile(loadFO);
addIndicesRefData(map);
BufferedWriter writer = createFile();
for (FeedRefData feedRefData : map.values()) {
try {
updateInstrumentAlias(map, feedRefData);
String refDataString = feedRefData.toString();
writer.write(refDataString, 0, refDataString.length());
writer.newLine();
writer.flush();
} catch (IOException e) {
e.printStackTrace();
log.info("Unable to write Quote Object to : " );
}
}
System.out.println("Ref Data File Generated:"+new Date());
For bind your method with progressbar you should do these steps :
Create a task which contains your method.
Create a thread which run this task.
Bind your progress property with your task property.
I made this simple example ,just change my code with your method code :
public class Bind extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
ProgressBar pb = new ProgressBar();
pb.setProgress(1.0);
Button button = new Button("start");
button.setOnAction((ActionEvent event) -> {
/*Create a task which contain method code*/
Task<Void> task = new Task<Void>() {
#Override
protected Void call() throws Exception {
File file = new File("C:\\Users\\Electron\\Desktop\\387303_254196324635587_907962025_n.jpg");
ByteArrayOutputStream bos = null;
try {
FileInputStream fis = new FileInputStream(file);
byte[] buffer = new byte[1024];
bos = new ByteArrayOutputStream();
for (int len; (len = fis.read(buffer)) != -1;) {
bos.write(buffer, 0, len);
updateProgress(len, file.length());
/* I sleeped operation because reading operation is quiqly*/
Thread.sleep(1000);
}
System.out.println("Reading is finished");
} catch (FileNotFoundException e) {
System.err.println(e.getMessage());
} catch (IOException e2) {
System.err.println(e2.getMessage());
}
return null;
}
};
Thread thread = new Thread(task);
thread.start();
/*bind the progress with task*/
pb.progressProperty()
.bind(task.progressProperty());
});
HBox box = new HBox(pb, button);
Stage stage = new Stage();
StackPane root = new StackPane();
root.getChildren().add(box);
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
}
Operation started :
Operation finished :
PS: I used Thread.sleep(1000) because my file is so small.You can remove it if your progress time is long.

while ((c = in.read(buffer)) != -1) {
out.write(buffer, 0, c);
}
out.flush();
}
}
public static void receive(HttpURLConnection conn) throws Exception {
try (BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()))) {

Here is Servlet code:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("Post request");
System.out.println(request.getContentLength());
try (BufferedReader br = new BufferedReader(new InputStreamReader(request.getInputStream()));

}
} catch (Exception ex) {

}
try (BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(response.getOutputStream()))) {
bw.write("Close connection!!!");
}
}
When i run client code in server console out appears
Post refquest
-1
request.getContentLength() always return -1
Why i cant send bytes to the servlet? Here is contains of file which bytes i am trying to send
["192","2","3","4","5","6","7","8","9","US"] ["194","2","3","4","5","6","7","8","9","US"]
Resovled. Problem was in "/" symbol in the end of url. it was absent. But in this case servlet has responded.

In this code,First database login_usr procedure execute properly,but when trying to execute 2nd procedure,which returns a cursor as outparameter,i'm getting above exception.If same code working fine on my PC,then why it throws exception when trying to execute callablestatement after Serverside deployment.Here I'm using Ojdbc14.jar and classes12.jar.Is there is any .jar missmatch..???
Thanks in advance.
As you have mentioned that the code was running earlier, Here the culprit could be OracleTypes. As its abstract class you need correct and concrete implementation of it which is your Driver.
Verify the version of the JDBC driver and the type of JDBC driver (Thin or OCI) you
Download new jar from oracle site or from here.
Also, try using oracle.jdbc.OracleTypes before looking for drivers.
e.g. cn.registerOutParameter(2, oracle.jdbc.OracleTypes.CURSOR);
How to redirect Glassfish server output into HttpServletResponse.out? I am making servlet in NetBeans.
here is a working example, just expose this as a servlet
public class ReadLogs extends HttpServlet {
private static final String CONTENT_TYPE = "text/html; charset=UTF-8";
public void init(ServletConfig config) throws ServletException {
super.init(config);
}
public void service(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
out.append("<html>\n<head>\n\n");
out.append("<script>function toBottom()" + "{"
+ "window.scrollTo(0, document.body.scrollHeight);" + "}");
out.append("\n</script>");
out.append("\n</head>\n<body onload=\"toBottom();\">\n<pre>\n");
try {
File file = new File("C:\\pathToServerLogFile");
BufferedReader in = new BufferedReader(new FileReader(file));
StringBuilder sb = new StringBuilder();
while (in.ready()) {
String x = in.readLine();
sb.append(x).append("<br/>");
}
in.close();
out.append("\n</pre>\n</body>\n</html>");
out.close();
} catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
}
UPDATE
If you need to print only the last portion of the file use this after line "in.close();"
//print only 1MB Oof data
if(sb.length()>1000000){
out.append(sb.substring(sb.length()-1000000, sb.length()));
}else{
out.append(sb.toString());
}
So.. to print only lines which appeared after invoking script I've made such code:
BufferedReader reader = new BufferedReader(new FileReader("/path/to/server/log/server.log"));
int lines = 0;
while (reader.readLine() != null) {
lines++;
}
reader.close();
BufferedReader reader2 = new BufferedReader(new FileReader("/path/to/server/log/server.log"));
String strLine;
int i = 0;
while (i != lines) {
reader2.readLine();
i++;
}
while ((strLine = reader2.readLine()) != null) {
out.println(stringToHTMLString(strLine));
out.println("<br>");
}
reader2.close();
When servlet starts it counts lines in server log (saves it in variable i), then after clicking on action form it read lines which indexes are higher than i and displays it on html page. I've used function stringToHTMLString which I found somewhere on stackoverflow.
