global root overflow(please help)

[sushant_125]

hi
i am getting an error of 'global root overflow' many a times whenever my midlet acesses data from a remote server using 'http' connection. This error occurs on the phone only and not on an emulator. The data read is from an xml file which lies on an IIS along with the server which creates it. What could be the problem please help!!!

Short answer: It's a Nokia bug

Long answer: You need to give more information about what devices you are using, and the nature of the problem. However, I have seen this problem before where the serer response is empty. You need to make sure that your http GET actually returns data.

As you have spotted, the emulators bear no resemblence to reality.

I have the same problem on a Nokia 6230, firmware 03.15. I never had this problem with firmware 03.14.
