solved 

alright i'll work it out thanks!

is ClientConnectionManagerListener  = JMEClientChannelListener ?

Hi guys,

currently, I'm trying to make a simple mini game on cell phone using SGSJME. The game requires clients to open channels and leave channels frequently. Basically, i understand that by opening a channel, we use clientMgr.openChannel("channel1");

My problem is, how do we leave or close that particular opened channel?   

Hi guys,

has anyone tried testing SGSME with an actual mobile device yet? I've tried running samples program like JMEChatClient on my iPAQ on a wireless network but not working well. I'm able to login into the SGSME server BUT the connection seems to die seconds after logging in.

1. Login success on mobile device (but gotta take quite some time, usually have to login more than once)
2. Login ChatTestClient (PC) <-- J2SE sample program

/** The Problem **/
3. PC able to see mobile device ID
4. BUT mobile device can't
5. PC sends a message to mobile device but mobile device didn't receive
6. Login 2nd PC Client
7. Mobile Device's userList still empty
/************************************************************************/

8. Login on mobile device Emulator
9. Mobile device Emulator able to see both PC's ID and able communicate

 

icic.., thanks for all the explanation. really appreciate it! 

wow, it works using this,
myId=new String(userId,0,userId.length>8?8:userId.length);
thanks!!   

but could you roughly explain to me the meaning of this line?
userId.length>8?8:userId.length

Hi guys,

I'm trying to reduce the length of IDs to 8 characters in J2ME. From what i see in J2SE, it works  perfectly fine doin this way
myID = StringUtils.bytesToHex(userID, userID.length - 4);

however in J2ME, it didn't work that way.   

nvm, problem solved. 

Hi Guys, I tried sending a simple message to the SGSJME Server but no luck.   
The error prompt: Uncaught exception java/lang/NullPointerException.
Below are part of my codes.
