问题
i have developed an application, that gets installed in the mobile phone. The brief information of application is it is accessing web services, from another machine. Now i tested the application on the simulator in 2 ways
1) MDS: in the application , there is a url of the machine, where web services are present. this url is in the stubs generated ,i make no changes to the url. and i start the MDS-cs server , Now the application works fine.
2) Direct TCP: to the url , i append ;deviceside=true to the url. and now, this time, i dont start the MDS-CS, and the application works in this case.
But, now when i install these files in the device, the application doesnt work. I havent tried it with MDS, becuase i need to take support from the blackberry team in our org. which would take more time. So i have tried it with, Direct TCP, i wiped the device and installed the application. but it does not work.Please help me , in this case.

Networking on a BlackBerry device can be a little complicated. I highly recommend going through this forum post for a primer on all of the issues and complexities involved with using HTTP on a BlackBerry. Lots of very useful information in there.
