Installing as a Windows Service

WSO2 Carbon and any Carbon-based product can be run as a Windows service as described in the following sections:

Prerequisites

Install JDK and set up the JAVA_HOME environment variable.
Download and install a service wrapper library to use for running your WSO2 product as a Windows service. WSO2 recommends Yet Another Java Service Wrapper (YAJSW) version 11.03, and several WSO2 products provide a default wrapper.conf file in their <PRODUCT_HOME>/bin/yajsw/ directory. The instructions below describe how to set up this file.

Setting up the YAJSW wrapper configuration file

The configuration file used for wrapping Java Applications by YAJSW is wrapper.conf, which is located in the <YAJSW_HOME>/conf/ directory and in the <PRODUCT_HOME>/bin/yajsw/ directory of many WSO2 products. Following is the minimal wrapper.conf configuration for running a WSO2 product as a Windows service. Open your wrapper.conf file, set its properties as follows, and save it in <YAJSW_HOME>/conf/ directory.

If you want to set additional properties from an external registry at runtime, store sensitive information like usernames and passwords for connecting to the registry in a properties file and secure it with secure vault.

You must manually add the following property to the wrapper.conf file to avoid errors in the management console:

wrapper.java.additional.26 = -Dorg.apache.jasper.compiler.Parser.STRICT_QUOTE_ESCAPING=false

If this property is not added, you may come across an exception that will result in blank pages when you sign into the product management console.

Setting up CARBON_HOME

Extract the Carbon-based product that you want to run as a Windows service, and then set the Windows environment variable CARBON_HOME to the extracted product directory location. For example, if you want to run ESB 4.5.0 as a Windows service, you would set CARBON_HOME to the extracted wso2esb-4.5.0 directory.

Running the product in console mode

You will now verify that YAJSW is configured correctly for running the Carbon-based product as a Windows service.

Open a Windows command prompt and go to the <YAJSW_HOME>/bat/ directory. For example:
```
cd C:\Documents and Settings\yajsw_home\bat
```
Start the wrapper in console mode using the following command:
```
runConsole.bat
```
For example:

If the configurations are set properly for YAJSW, you will see console output similar to the following and can now access the WSO2 management console from your web browser via https://localhost:9443/carbon.

Working with the WSO2CARBON service

To install the Carbon-based product as a Windows service, execute the following command in the <YAJSW_HOME>/bat/ directory:

installService.bat

The console will display a message confirming that the WSO2CARBON service was installed.

To start the service, execute the following command in the same console window:

startService.bat

The console will display a message confirming that the WSO2CARBON service was started.

To stop the service, execute the following command in the same console window:

stopService.bat

The console will display a message confirming that the WSO2CARBON service has stopped.

To uninstall the service, execute the following command in the same console window:

uninstallService.bat

The console will display a message confirming that the WSO2CARBON service was removed.
