Http polling

Hi,

I try to use http polling to connect a JS client to my ejabberd server. I manage to do that with my IE browser even if i have an alert message but it doesn't work with firefox . I don't know why i can't do a XMLHttpRequest.open on firefox !

I let you my error message :

[Exception... "Component returned failure code: 0xc1f30001 (NS_ERROR_NOT_INITIALIZED) [nsIXMLHttpRequest.send]" nsresult: "0xc1f30001 (NS_ERROR_NOT_INITIALIZED)" location: "JS frame :: file:///../jsjac/clientJabber/JSJaCHttpPollingConnection.js :: JSJaCHPCConnect :: line 203" data: no]

Thanks for your help,

Nicolas
