http://sqeweb/jsn/users/fred/deployment_ws/reappear/deployment_6_UR_int_ws/deployment/src/plugin/FunctionalTest/FunctionalTest/src/AppletCreated.java
The function implemented by javascript can be found on:

http://sqeweb/jsn/users/fred/deployment_ws/reappear/deployment_6_UR_int_ws/deployment/src/plugin/FunctionalTest/FunctionalTest/html/AddAppletScript.html
