    <p>I'm running some unit tests on some EJBS via maven and an embedded glassfish container. One of my tests works, but all subsequent attempts to test a different EJB result in the same error:</p> <pre><code>java.lang.ClassCastException: $Proxy81 cannot be cast to </code></pre> <p>Followed by whatever bean I'm attempting to test. I'm confident my setup is good since, as I say, one of my beans can be tested properly.</p> <p>Examples of workiing code:</p> <pre><code>@Stateful public class LayoutManagerBean implements LayoutManager { private final Log LOG = LogFactory.getLog(LayoutManagerBean.class); public List&lt;Menu&gt; getMenus(User currentUser) { ... } } @Local public interface LayoutManager { public List&lt;Menu&gt; getMenus(User user); } </code></pre> <p>And the test:</p> <pre><code>public class LayoutManagerTest { private static EJBContainer ejbContainer; private static Context ctx; @BeforeClass public static void setUp() { ejbContainer = EJBContainer.createEJBContainer(); ctx = ejbContainer.getContext(); } @AfterClass public static void tearDown() { ejbContainer.close(); } @Test public void getMenus() { LayoutManager manager = null; try { manager = (LayoutManager) ctx.lookup("java:global/classes/LayoutManagerBean!uk.co.monkeypower.openchurch.core.layout.beans.LayoutManager"); } catch (NamingException e) { System.out.println("Failed to lookup the gosh darned bean!"); } assertNotNull(manager); //Menu[] menus = manager.getMenus(); //assertTrue(menus.length &gt; 1); } } </code></pre> <p>And an example of a failure:</p> <pre><code>@Singleton public class OpenChurchPortalContext implements PortalContext { private Set&lt;PortletMode&gt; portletModes = Collections.emptySet(); private Set&lt;WindowState&gt; windowStates = Collections.emptySet(); private Properties portalProperties = new Properties(); public OpenChurchPortalContext() { portletModes.add(PortletMode.VIEW); portletModes.add(PortletMode.HELP); portletModes.add(PortletMode.EDIT); portletModes.add(new PortletMode("ABOUT")); windowStates.add(WindowState.MAXIMIZED); windowStates.add(WindowState.MINIMIZED); windowStates.add(WindowState.NORMAL); } ... } </code></pre> <p>And the test:</p> <pre><code>public class OpenChurchPortalContextTest { private static EJBContainer ejbContainer; private static Context ctx; @BeforeClass public static void setUp() { ejbContainer = EJBContainer.createEJBContainer(); ctx = ejbContainer.getContext(); } @AfterClass public static void tearDown() { ejbContainer.close(); } @Test public void test() { OpenChurchPortalContext context = null; try { context = (OpenChurchPortalContext) ctx.lookup("java:global/classes/OpenChurchPortalContext"); } catch (NamingException e) { System.out.println("Failed to find the bean in the emebedded jobber"); } assertNotNull(context); Set&lt;PortletMode&gt; modes = (Set&lt;PortletMode&gt;) context.getSupportedPortletModes(); assertTrue(modes.size() &gt; 1); Set&lt;WindowState&gt; states = (Set&lt;WindowState&gt;) context.getSupportedWindowStates(); assertTrue(states.size() &gt; 1); } } </code></pre> <p>Any ideas as to why this may not be working?</p>

    1. COI can't propose a solution without knowing more about the code but maybe you can try to create two as-compact-as-possible projects, one with a succesful test and one with a failing test. Then you will either find the solution or at least you will be able to share your code for others to investigate.

    2. COOK - I'm trying to post some example code, but it is proviing problematic in Firefox. Will keep trying.

    3. COOnce difference that I can see is that the failing bean is a @Singleton and the working one is a stateful session bean being looked up via local interface.

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).
