Start wildfly service with standalone-full.xml

By kris -
Wildfly provides a service.bat in %WILDFLY_HOME%\bin\service. Calling the batch file with the install parameter installs Wildfly as a service on Windows. Once it is installed on windows, you can change the settings so that wildfly starts all the modules and services instead of default minimal setup. For this, change standalone.bat file and add this line : set "SERVER_OPTS=--server-config=standalone-full.xml" This will enable startup of all modules & services of wildfly from now on.
