There is also a running coldfusinsvc.exe (which is the ColdFusion Service Application) which might interest you as well.
CF10 onwards the application server is CF+Tomcat bundle. | JRUN is the underlying application server used by Adobe ColdFusion 8 and 9. Other version or flavours of CF runtimes and engines are dependent on the underlying server technology such as Tomcat, JBoss, Webspehere etc. Some common process names are java.exe, tomcat.exe, jrun.exe |

```
var iconBase = 'https://maps.google.com/mapfiles/kml/shapes/';
var marker = new google.maps.Marker({

map: map,
icon: iconBase + 'schools_maps.png'
