Why I got a Open tunnel - failure while http connection?
 

Hello ! I have develooped a J2ME application, and tested on many devices on DeviceAnyWhere. It is found that on some platform ,for example , BlackBerry 8800 (OS 4.2.1.79) , a Open tunnel - failure Exception appears and unable to connect to network. I made a http connection without any parameters, wishing to receiving or sending data through the BlackBerry MDS Connection Service. But failed . Could anyone help me on this issue? Thanks!
