    <p>Failing to connect to Tomcat JMX instance</p> <p>Ok i am stuck now - Im trying to configure JMX with Tomcat as follows</p> <p><code>$CATALINA_BASE/setenv.sh</code>:</p> <pre><code>CATALINA_OPTS="-Dcom.sun.management.jmxremote.port=18070 -Dcom.sun.management.jmxremote.password.file=$CATALINA_BASE/conf/jmxremote.password -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.access.file=$CATALINA_BASE/conf/jmxremote.access" export CATALINA_OPTS </code></pre> <p><code>$CATALINA_BASE/conf/jmxremote.password</code></p> <pre><code> monitorRole monitorpass controlRole controlpass </code></pre> <p><code>$CATALINA_BASE/conf/jmxremote.access</code></p> <pre><code> monitorRole readonly controlRole readwrite </code></pre> <p>The client tool i am using to access the Tomcat JMX server is running on the same machine as the Tomcat instance. when i start tomcat i can see that there is something listening at port 18070 but when i try to connect i get the following error</p> <pre><code> Exception in thread "main" java.lang.SecurityException: Authentication failed! Credentials required at com.sun.jmx.remote.security.JMXPluggableAuthenticator.authenticationFailure(JMXPluggableAuthenticator.java:193) at com.sun.jmx.remote.security.JMXPluggableAuthenticator.authenticate(JMXPluggableAuthenticator.java:145) at sun.management.jmxremote.ConnectorBootstrap$AccessFileCheckerAuthenticator.authenticate(ConnectorBootstrap.java:185) at javax.management.remote.rmi.RMIServerImpl.doNewClient(RMIServerImpl.java:213) </code></pre> <p>I connect using the following bit of code</p> <pre><code> try { url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://localhost:18070/jmxrmi"); jmxc = JMXConnectorFactory.connect(url,null); mbsc = jmxc.getMBeanServerConnection(); } catch (MalformedURLException e) { throw new Exception(methodName + ":" + e); } catch (IOException e) { throw new Exception(methodName + ":" + "Failed to connect to the Tomcat Server " + e); } </code></pre> <p>It works fine if i set com.sun.management.jmxremote.authenticate=true to false. Other than that it just fails. The client tool is running on the same machine as the tomcat instance so there should not be any issues with the firewall. Any clues </p>

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.
