Not able to access amf channel from Mobile Devices(IPAD)

Hi All,

     I have created an Flex mobile project for IPad.I have cloud server where I have deployed my Java classes in Tomcat.My Problem is I am not able to access the amf channel when I install my application's IPA file to IPad.But when I package it as an AIR application and install it on the desktop it works fine.Also if I run it from Flash Builder 4.5 I am able to access the amf channel and able to communicate to the Java Classes.Also I am not able to access any of the website on the mobile devices hosted on that particular server but able to access it from desktop.So what could be the reason?Do I need to configure anything in my Tomcat to allow requests from the Mobile devices or is there anything else stopping us from accessing the amf channel from mobile devices ?

Thanks & Regards
