    <p>I'm working on a project where I want to use Interceptors to log usage of a ManagedBean. As I read in the specs and in many examples it should be possible with the current CDI implementations. The code is mainly copied from examples like the Glassfish JavaEE Tutorial or other sources I found on the web. There is no special implementation in it. It should only log. </p> <p>What I try was the following: </p> <p>LoggedInterceptor.java</p> <pre><code>package test.interceptors; import java.io.Serializable; import javax.interceptor.AroundInvoke; import javax.interceptor.Interceptor; import javax.interceptor.InvocationContext; @Logged @Interceptor public class LoggedInterceptor implements Serializable { private static final long serialVersionUID = 1L; public LoggedInterceptor() { } @AroundInvoke public Object logMethodEntry(InvocationContext invocationContext) throws Exception { System.out.println( "Entering method: " + invocationContext.getMethod().getName() + " in class " + invocationContext.getMethod().getDeclaringClass().getName()); return invocationContext.proceed(); } } </code></pre> <p>Logged.java</p> <pre><code>package test.interceptors; import static java.lang.annotation.ElementType.TYPE; import static java.lang.annotation.ElementType.METHOD; import static java.lang.annotation.RetentionPolicy.RUNTIME; import java.lang.annotation.Inherited; import java.lang.annotation.Retention; import java.lang.annotation.Target; import javax.interceptor.InterceptorBinding; @Inherited @InterceptorBinding @Retention(RUNTIME) @Target({ METHOD, TYPE }) public @interface Logged { } </code></pre> <p>WEB-INF/beans.xml</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns /javaee/beans_1_0.xsd"&gt; &lt;interceptors&gt; &lt;class&gt;test.interceptors.LoggedInterceptor&lt;/class&gt; &lt;/interceptors&gt; &lt;/beans&gt; </code></pre> <p>MainController.class</p> <pre><code>// ... All imports @Named @SessionScoped @Logged public class MainController implements Serializable { // Code goes here } </code></pre> <p>What I get is a class not found Exception from the WELD Resource Loader. </p> <pre><code> [#|2011-04-04T14:03:37.394+0200|SEVERE|glassfish3.1|javax.enterprise.system.tools.admin.org.glassfish.deployment.admin|_ThreadID=31;_ThreadName=Thread-1;|Exception while loading the app : Error loading class test.interceptors.LoggedInterceptor org.jboss.weld.resources.spi.ResourceLoadingException: Error loading class test.interceptors.LoggedInterceptor at org.jboss.weld.resources.DefaultResourceLoader.classForName(DefaultResourceLoader.java:61) at org.jboss.weld.manager.Enabled$ClassLoader.apply(Enabled.java:67) at org.jboss.weld.manager.Enabled$ClassLoader.apply(Enabled.java:55) at com.google.common.collect.Lists$TransformingRandomAccessList.get(Lists.java:435) at java.util.AbstractList$Itr.next(AbstractList.java:345) at org.jboss.weld.manager.Enabled.createMetadataMap(Enabled.java:130) at org.jboss.weld.manager.Enabled.&lt;init&gt;(Enabled.java:100) at org.jboss.weld.manager.Enabled.of(Enabled.java:82) at org.jboss.weld.bootstrap.BeanDeployment.&lt;init&gt;(BeanDeployment.java:104) at org.jboss.weld.bootstrap.WeldBootstrap$DeploymentVisitor.visit(WeldBootstrap.java:185) at org.jboss.weld.bootstrap.WeldBootstrap$DeploymentVisitor.visit(WeldBootstrap.java:156) at org.jboss.weld.bootstrap.WeldBootstrap.startContainer(WeldBootstrap.java:287) at org.glassfish.weld.WeldDeployer.event(WeldDeployer.java:167) at org.glassfish.kernel.event.EventsImpl.send(EventsImpl.java:128) at org.glassfish.internal.data.ApplicationInfo.load(ApplicationInfo.java:262) at com.sun.enterprise.v3.server.ApplicationLifecycle.deploy(ApplicationLifecycle.java:460) at com.sun.enterprise.v3.server.ApplicationLifecycle.deploy(ApplicationLifecycle.java:240) at org.glassfish.deployment.admin.DeployCommand.execute(DeployCommand.java:370) at com.sun.enterprise.v3.admin.CommandRunnerImpl$1.execute(CommandRunnerImpl.java:355) at com.sun.enterprise.v3.admin.CommandRunnerImpl.doCommand(CommandRunnerImpl.java:370) at com.sun.enterprise.v3.admin.CommandRunnerImpl.doCommand(CommandRunnerImpl.java:1067) at com.sun.enterprise.v3.admin.CommandRunnerImpl.access$1200(CommandRunnerImpl.java:96) at com.sun.enterprise.v3.admin.CommandRunnerImpl$ExecutionContext.execute(CommandRunnerImpl.java:1247) at com.sun.enterprise.v3.admin.CommandRunnerImpl$ExecutionContext.execute(CommandRunnerImpl.java:1235) at com.sun.enterprise.v3.admin.AdminAdapter.doCommand(AdminAdapter.java:465) at com.sun.enterprise.v3.admin.AdminAdapter.service(AdminAdapter.java:222) at com.sun.grizzly.tcp.http11.GrizzlyAdapter.service(GrizzlyAdapter.java:168) at com.sun.enterprise.v3.server.HK2Dispatcher.dispath(HK2Dispatcher.java:117) at com.sun.enterprise.v3.services.impl.ContainerMapper.service(ContainerMapper.java:234) at com.sun.grizzly.http.ProcessorTask.invokeAdapter(ProcessorTask.java:822) at com.sun.grizzly.http.ProcessorTask.doProcess(ProcessorTask.java:719) at com.sun.grizzly.http.ProcessorTask.process(ProcessorTask.java:1013) at com.sun.grizzly.http.DefaultProtocolFilter.execute(DefaultProtocolFilter.java:225) at com.sun.grizzly.DefaultProtocolChain.executeProtocolFilter(DefaultProtocolChain.java:137) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:104) at com.sun.grizzly.DefaultProtocolChain.execute(DefaultProtocolChain.java:90) at com.sun.grizzly.http.HttpProtocolChain.execute(HttpProtocolChain.java:79) at com.sun.grizzly.ProtocolChainContextTask.doCall(ProtocolChainContextTask.java:54) at com.sun.grizzly.SelectionKeyContextTask.call(SelectionKeyContextTask.java:59) at com.sun.grizzly.ContextTask.run(ContextTask.java:71) at com.sun.grizzly.util.AbstractThreadPool$Worker.doWork(AbstractThreadPool.java:532) at com.sun.grizzly.util.AbstractThreadPool$Worker.run(AbstractThreadPool.java:513) at java.lang.Thread.run(Thread.java:619) Caused by: java.lang.ClassNotFoundException: test.interceptors.LoggedInterceptor at com.sun.enterprise.loader.ASURLClassLoader.findClassData(ASURLClassLoader.java:808) at com.sun.enterprise.loader.ASURLClassLoader.findClass(ASURLClassLoader.java:696) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at org.jboss.weld.resources.DefaultResourceLoader.classForName(DefaultResourceLoader.java:52) ... 42 more </code></pre>

    1. COThe code looks certainly good. Can you describe your deployment (war? / ear? / structure?) Do you have the chance to push it to JBoss 6?

    2. CO@jan-groth Hi, thanks for your reply. The Code is deployed as an ear. The ear includes two EJB Jars and a war-file. The interceptors should be used by the ManagedBeans in the war file. Sorry but Glassfish is mandatory there is no JBoss installation available.

    3. COTry moving the interceptor code into the war and see if it's still not working. There is an classpath issue with Weld and EAR deployments...

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).
