    <p>I am entering some code into a Hudson Server run on a Ubuntu box in order to run some Code Metrics(Sonar) and Cobertura on the code. The project runs off of Glassfish3.1, uses Maven3, written in Java, JSF 2.0 and uses OracleXE Database(irrelevant).</p> <p>The error is being thrown when trying to create an instance of an Facade inside of my JUnit tests. The tests run fine when I am running them from Netbeans, but when Hudson does the automatic build on it I get this error:</p> <pre><code> java.lang.ClassCastException: $Proxy96 cannot be cast to ticket.app.DatesFacade at ticket.app.EventsControllerTest.setUp(EventsControllerTest.java:60) at junit.framework.TestCase.runBare(TestCase.java:128) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:120) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.maven.surefire.junit.JUnitTestSet.execute(JUnitTestSet.java:207) at org.apache.maven.surefire.junit.JUnit3Provider.executeTestSet(JUnit3Provider.java:107) at org.apache.maven.surefire.junit.JUnit3Provider.invoke(JUnit3Provider.java:79) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.maven.surefire.booter.ProviderFactory$ClassLoaderProxy.invoke(ProviderFactory.java:103) at $Proxy0.invoke(Unknown Source) at org.apache.maven.surefire.booter.SurefireStarter.invokeProvider(SurefireStarter.java:145) at org.apache.maven.surefire.booter.SurefireStarter.runSuitesInProcess(SurefireStarter.java:87) at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:69) </code></pre> <p>The Hudson server is not run off of JBoss, it is run off of Tomcat.

Querying!

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).
