Javascript Integration configuration parameters required in Oracle Forms 11g

Hi,

I am looking for the mandatory configuration parameters for enabling JavaScript Integration with Oracle forms 11g application.

As per Oracle documentation, enableJavascriptEvent parameter in formsweb.cfg needs to be set to TRUE to enable JavaScript integration. But there is no mention of other parameters are required
for it.

What happens if JavaScriptBlocksHeartBeat parameter is false, FORMS_TIMEOUT, heartbeat, networkRetries parameters are not added to either formsweb.cfg or default.env files?

Also, what does applet_stop_timeout="800" mean in base.html, basejpi.html, webutiljpi.htm files?

Thank you. 

Regards,
Haritha.
