Jconsole configuration - Tomcat

-

JMX local/remote monitoring configuration for tomcat using JConsole.

Start tomcat with the following self-explanatory params.

1. -Dcom.sun.management.jmxremote=true

2. -Dcom.sun.management.jmxremote.port=8181

3. -Dcom.sun.management.jmxremote.authenticate=false

4. -Dcom.sun.management.jmxremote.ssl=false

These two params are to solve RMI transport issues of java 1.6

5. -Djava.rmi.server.hostname=localhost

6. -Djava.net.preferIPv4Stack=true


Unix/Linux

export CATALINA_OPTS="-Dcon.sun.management.jmxremote=true

-Dcom.sun.management.jmxremote.port=8181

-Dcom.sun.management.jmxremote.authenticate=false

-Dcom.sun.management.jmxremote.ssl=false"

Windows

On windows set each parameter separately, otherwise you must use line separator (\).

set CATALINA_OPTS=-Dcom.sun.management.jmxremote=true

set CATALINA_OPTS=%CATALINA_OPTS% -Dcom.sun.management.jmxremote.port=8181

set CATALINA_OPTS=%CATALINA_OPTS% -Dcom.sun.management.jmxremote.authenticate=false

set CATALINA_OPTS=%CATALINA_OPTS% -Dcom.sun.management.jmxremote.ssl=false

Jconsole

1. Start Jconsole from command prompt

2. Select Remote Process

3. Enter the url as

service:jmx:rmi:///jndi/rmi://localhost:8686/jmxrmi

4. Click connect

Now the JMX client will get connected. You are all set to go.

RMI problem on java 1.6

Sometimes RMI fails to connect on java version 1.6. To solve this use.

-Djava.rmi.server.hostname=[hostname or IP ] -Djava.net.preferIPv4Stack=true

Log4j multiple WAR files in single EAR configuration

Log4j multiple WAR files in single EAR configuration Problem: When you have multiple WAR files under the same EAR with multiple log4j config files in each of the war files, the logging API will pickup the first available config file and ignores the list. i.e, only a single log4j config file applies to entire EAR. Consider the below app app.ear |__admin.war    |__WEB-INF/classes/log4.xml |__web.war    |__WEB-INF/classes/log4j.xml When you deploy this app to the server all logs of two war files admin.war and web.war will go to admin.war' log. The log4j.xml in web.war has no effect here. There are some complex solutions for this like adding a logback, specifying package level log files in log4j configuration etc. Solution The easiest way is configuring the context param in web.xml In your web.xml add the following context param will send the log4j config locations specific to the contexts and fixes this issue. web.war/WEB-INF/classes/log4j.xml <conte

File Watch Service The NIO2 WatchService API provides the ability for java code to watch for file modifications in a directory in the filesystem. A WatchService object watches the folder it is registered with and signals the changes detected through event notifications.  Steps to create a WatchService Create a WatchService object (FileSystem.newWatchService()) Register the directories to be watched with the WatchService (WatchService.register()) Watch for file change events (poll()/take() methods) Retrieve the event keys and process them Rest the key and got to step 3 to watch again. Example code Below is a simple working code. import java.io.IOException; import java.nio.file.Path; import java.nio.file.Paths; import java.nio.file.StandardWatchEventKinds; import java.nio.file.WatchEvent; import java.nio.file.WatchKey; import java.nio.file.WatchService; import java.util.List; import java.util.concurrent.TimeUnit; public class FileWatcherTest { private static
