GLOBE IMS, ctelephony, etel3rdparty, j2me, travel portal :D
Our company recently join the GLOBE IMS Challenge which focuses on using IMS technology on mobile. Many things are possible using Ericsson's SDS4 SDK such as the connectivity between different devices from mobile to TV to PS2 it's really amazing. Unfortunately this technology is new in it's nature limiting the developer like me to what we can develop. Its ericsson's so target mobile are also ericsson's and we are advised to use P990i, P1 etc. SJP3.4 I think which doesn't have Location API such as JP7.
Now, the main module of our project will use Location API so I was force to use C++ for Symbian Programming using the ctelephony class from etel3rdparty.lib. I was successful in making getting the Location data in Symbian such as Cell ID, Location Area Code, etc. However, my main problem right now is how will I compile the DLL in such a way that I can call it in a java code using JNI which, luckily is supported by most P990i phones. I've tried JNI in windows however, I'm not sure about it's compilation in mobile.
Well, for me to not forget my code here it is :D

Actually parts of the code are from sonyericsson and developer.symbian and the uiq 3 documentation the .chm file. I've just paste them together :-).
Currently, I am doing 2 other major projects in short I am really busy and I haven't touch this project for days. For record the other 2 are:
1.) a Travel web Portal wherein you can book your flights online (search for flights and it's info - how much, when, etc.)
.) J2ME project that will cater the department stores, items' inventory will now be inventoried though mobile using GPRS so a not so very high model phone is required.:D
See I was quite versatile and now I'm writing this 'coz my head is about to explode buwahahaha....
