To make Tomcat Webserver start automatically on system startup

·         Open <TOMCAT-HOME>\BIN\service.bat  file

·         Look for this line:

"%EXECUTABLE%" //US//%SERVICE_NAME% --JvmOptions "-Dcatalina.base=%CATALINA_BASE%;-Dcatalina.home=%CATALINA_HOME%;-Djava.endorsed.dirs=%CATALINA_HOME%\common\endorsed" --StartMode jvm --StopMode jvm

·         Replace it with something like this:

"%EXECUTABLE%" //US//%SERVICE_NAME% --JvmOptions "-Dcatalina.base=%CATALINA_BASE%;-Dcatalina.home=%CATALINA_HOME%;-Djava.endorsed.dirs=%CATALINA_HOME%\common\endorsed;-Dfile.encoding=UTF8;-Duser.timezone=GMT;-Djava.security.auth.login.config=%CATALINA_HOME%\conf\jaas.config;" --StartMode jvm --StopMode jvm

·         Also change the maximum heap size of the JVM: (It should be at least 512)

"%EXECUTABLE%" //US//%SERVICE_NAME% ++JvmOptions "-Djava.io.tmpdir=%CATALINA_BASE%\temp" --JvmMs 128 --JvmMx 256

·         Open up a command prompt and navigate to tomcat/bin:

tomcat/bin>service.bat install

·         Type the command services.msc in Start -> Run window

·         Start the Apache Tomcat service and make its startup type as Automatic.
