    <p>I'm trying to do a JavaFX Application that can receive command line parameters. I can receive the parameters. But I'm having problems when I instanciate the "A" class (from Main.java) that has Selenium (Testing/WebBrowser Automation Library) members inside.</p> <pre><code>// Main.java package myPackage; import java.util.Map; import javafx.application.Application; import javafx.stage.Stage; public class Main extends Application { @Override public void start(Stage stage) { if (getParameters().getRaw().isEmpty() == false) { System.out.println("The application was called by Command Line."); Map&lt;String, String&gt; params = getParameters().getNamed(); System.out.println(params.get("a")); A myA = new A(); } else { System.out.println("The application was called executing the jar file."); A myA = new A(); } } public static void main(String[] args) { launch(args); } } </code></pre> <hr> <pre><code>// A.java package myPackage; import org.openqa.selenium.By; import org.openqa.selenium.NoSuchElementException; import org.openqa.selenium.chrome.ChromeDriver; public class A { ChromeDriver driver; A() { System.out.println("New A Instance."); System.setProperty("webdriver.chrome.driver", "C:\\chromedriver_win32\\chromedriver.exe"); this.driver = new ChromeDriver(); } public boolean isElementPresent(By by) { try { this.driver.findElement(by); return true; } catch (NoSuchElementException ex) { return false; } } } </code></pre> <p><strong>But when I try to execute it with:</strong> <code>java -cp MyProject.jar myPackage.Main --a="value1"</code></p> <pre><code>The application was called by Command Line. value1 Exception in Application start method java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) at com.sun.javafx.application.LauncherImpl.launchApplicationWithArgs(LauncherImpl.java:367) at com.sun.javafx.application.LauncherImpl.launchApplication(LauncherImpl.java:305) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:483) at sun.launcher.LauncherHelper$FXHelper.main(LauncherHelper.java:767) Caused by: java.lang.RuntimeException: Exception in Application start method at com.sun.javafx.application.LauncherImpl.launchApplication1(LauncherImpl.java:894) at com.sun.javafx.application.LauncherImpl.access$000(LauncherImpl.java:56) at com.sun.javafx.application.LauncherImpl$1.run(LauncherImpl.java:158) at java.lang.Thread.run(Thread.java:744) Caused by: java.lang.NoClassDefFoundError: org/openqa/selenium/NoSuchElementException at myPackage.Main.start(Main.java:16) at com.sun.javafx.application.LauncherImpl$8.run(LauncherImpl.java:837) at com.sun.javafx.application.PlatformImpl$7.run(PlatformImpl.java:331) at com.sun.javafx.application.PlatformImpl$6$1.run(PlatformImpl.java:297) at com.sun.javafx.application.PlatformImpl$6$1.run(PlatformImpl.java:294) at java.security.AccessController.doPrivileged(Native Method) at com.sun.javafx.application.PlatformImpl$6.run(PlatformImpl.java:294) at com.sun.glass.ui.InvokeLaterDispatcher$Future.run(InvokeLaterDispatcher.java:95) at com.sun.glass.ui.win.WinApplication._runLoop(Native Method) at com.sun.glass.ui.win.WinApplication.access$300(WinApplication.java:39) at com.sun.glass.ui.win.WinApplication$4$1.run(WinApplication.java:112) ... 1 more Caused by: java.lang.ClassNotFoundException: org.openqa.selenium.NoSuchElementException at java.net.URLClassLoader$1.run(URLClassLoader.java:359) at java.net.URLClassLoader$1.run(URLClassLoader.java:348) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:347) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 12 more Exception running application myPackage.Main </code></pre> <p>As you can see, the app get the parameter and prints it (first and second line in this output above)...</p> <p>I read that line <code>NoClassDefFoundError: org/openqa/selenium/NoSuchElementException</code> but selenium library (2.37.0) is added, and the libs dependencies too. In Netbeans in the <code>Libraries &gt; Compile</code> tab</p> <p>If I run the application using Netbeans <code>Project properties &gt; run &gt; parameters</code> and inserting one parameter all is fine. The problem comes when I do the same by Command Line...</p> <p>I have tried a LOT of things... and I Can't Understand, why ?</p>

    1. COYou probably need to add the library to the classpath when executing the application. What you do in Netbeans only takes effect when launching from Netbeans.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
