xpcom and javascript

[Christian Reichlin]

hi,

i'm trying to make an activity out of a javascript application. i load 
the page into a hulahop webview-widget and i can access the dom with 
xpcom to save the state to the journal. for restoring the state i need 
to call a javascript function and i wasn't able to figure out how to do 
this.
if someone knows how to do this or if someone has another solution to 
this problem it would be great.

thanks
chrigi
