First of all I would check the HTTP proxy settings on your device. Also check that the dial-in configuration is correct. Now verify that network connections work at all by using the Web browser or e-mail client on the device.
I doubt that this problem is related to the network operator, or to the fact that your application is written in Java. After all, your MIDlet just opens a straight HTTP connection.
Also check the HTTP log file on your web server / sevlet engine. Could be that your device opens a HTTP 1.0 connection, whereas your Web server expects HTTP 1.1. This is a problem we have encountered when we connected MIDlets on the Siemens SL45i to Jakarta Tomcat.
