    <p>I downloaded the OperaDriver from <a href="https://github.com/operasoftware/operadriver/" rel="nofollow">https://github.com/operasoftware/operadriver/</a> and tried to run the simple/Example.java But I always get an exception "java.net.BindException: Address already in use"? I don't understand how this BindException can occur? How do I found out which port is already occupied? It is not printed out in the stack trace? Where does the OperaDriver run by default?</p> <p>Here is the full stack trace:</p> <pre><code>Jun 29, 2011 10:35:16 AM com.opera.core.systems.OperaDriver &lt;init&gt; SEVERE: Error initializing OperaDriver with exception org.openqa.selenium.WebDriverException: java.net.BindException: Address already in use Build info: version: '2.0rc3', revision: '12536', time: '2011-06-20 18:19:52' System info: os.name: 'Linux', os.arch: 'i386', os.version: '2.6.34.8-0.2-desktop', java.version: '1.6.0_24' Driver info: driver.version: OperaDriver at com.opera.core.systems.OperaDriver.createScopeServices(OperaDriver.java:233) at com.opera.core.systems.OperaDriver.init(OperaDriver.java:192) at com.opera.core.systems.OperaDriver.&lt;init&gt;(OperaDriver.java:147) at com.opera.core.systems.OperaDriver.&lt;init&gt;(OperaDriver.java:105) at ch.adnovum.wci.test.common.DriverFactory.getDriver(DriverFactory.java:132) at ch.adnovum.wci.test.web.UpAndRunningTest.testCustomerAppOpera(UpAndRunningTest.java:62) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:76) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:49) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) Caused by: java.net.BindException: Address already in use at sun.nio.ch.Net.bind(Native Method) at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:126) at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:59) at sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:52) at com.opera.core.systems.scope.stp.StpConnectionListener.start(StpConnectionListener.java:80) at com.opera.core.systems.scope.stp.StpConnectionListener.&lt;init&gt;(StpConnectionListener.java:53) at com.opera.core.systems.scope.stp.StpThread.&lt;init&gt;(StpThread.java:44) at com.opera.core.systems.ScopeServices.&lt;init&gt;(ScopeServices.java:175) at com.opera.core.systems.OperaDriver.createScopeServices(OperaDriver.java:230) ... 27 more </code></pre>

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).
