Java Service Wrapper Example



As operating system environment variables (example for win32: set wrapper.java=c: java jdk1.5 bin java.exe) Properties are searched in this order. Thus setting wrapper.java configuration in system properties will override the OS environment. Hello everyone, We are proud to announce the release of version 3.5.39 of the Java Service Wrapper. 1.8.0191 I can run the jar file on Linux with no problem. java -jar example.jar I used method 4 to wrap the jar file and when I run it, I get an.

Tools > Java Service Wrapper

This page provides some useful information on running the ActiveMQ broker as a windows-NT service or a daemon thread in Linux or Unix systems.

  1. The Java Service Wrapper records console output in a log file. The log contains the output sent to the console by the wrapper itself and by the Universal Messaging component running in the wrapper. The wrapper log is especially useful when you run the component as a Windows service because console output is normally not available to you in this.
  2. The wrapper.java.command property for example will automatically quote the string so you can just use it as is. Wrapper.java.additional and wrapper.app.parameter properties both require you to decide how you want the quotes handled so they will work on all supported platforms. If the service is a Wrapper service, you can use 'wrapper.exe -p.
  3. Programmers should be careful to avoid some common mistakes. For example, always shutting down the executor service after the completion of tasks and services that are no longer needed. Otherwise, JVM will never terminate, normally. In this tutorial, we covered each and every concept of Executor service in Java.

64bit 4gb memory limit

The ActiveMQ distribution uses an older and free community release of the service wrapper library. This wrapper has a memory limit of 4gb when running on 64bit platforms. You can manually download a newer release of the wrapper library that does not have this limit, from the vendors website at. It us not possible for Apache ActiveMQ to update and distribute a newer release of the service wrapper, as the vendor changed licensing terms, which does not comply with ASF licensing terms. Therefore out of the box the service wrapper is stuck on that older release.

However you can manually upgrade the library.

Windows-NT Service

Here are the steps to install the ActiveMQ broker as an NT service:

  1. Download the windows binary distribution (i.e. apache-activemq-5.9.0.zip)
  2. Go to ACTIVEMQ_HOME/bin/win32
  3. Run InstallService.bat

After running InstallService.bat, the ActiveMQ service should be added to the list of NT services. It is not started by default.

To verify, go to control panel -> administrative tools -> services and look for the ActiveMQ service. Here you can start the ActiveMQ service or configure it to start automatically every time the system boots.

To remove the ActiveMQ service:

  1. Run UninstallService.bat

Linux/Mac OS X Daemon

Here are the steps to run the ActiveMQ broker as a daemon in Linux or Unix systems:

  1. Download the linux/unix binary distribution (i.e. apache-activemq-5.9.0.tar.gz)
  2. Go to ACTIVEMQ_HOME/linux for linux systems or ACTIVEMQ_HOME/macosx for Mac OS X systems.
  3. Run ./activemq start

To stop the daemon process:

  1. Go to ACTIVEMQ_HOME/linux for linux systems or ACTIVEMQ_HOME/macosx for Mac OS X systems.
  2. Run ./activemq stop

Configuring the Java Service Wrapper

ActiveMQ uses the Java Service Wrapper to run the broker. To configure how the Java Service Wrapper starts up, you can edit the wrapper.conf located in the bin/win32, bin/linux, or bin/macosx depending on which system you are running it. For more information on the different properties of the Java Service Wrapper, refer to this page

Troubleshooting

If you are having problems running the service, turn on the wrapper debugging in the corresponding wrapper.conf file via (wrapper.debug=TRUE)

Each time you run the wrapper, a log file will be created in ACTIVEMQ_HOME/data/wrapper.log
