when it comes to httpconnection with 6600, it will mainly be a problem with multiple thread trying to connect through http. please check if you are maintaining the threading correctly, if there are 2 threads trying to connect to a url some phones which you listed throw error. So tune your code insuch a way that there are only one http object at any time.

Hi
I am using 3 canvas and in each canvas i am using class for server connection.I have 3 games in a package.
For example in the game1canvas i have a thread and i am using server connection in the game1class.In the game1server i am opening the http connection 5 times and closing the connection after i have used it.
So the same things in all the three canvas.
So now tell me in what place i am making mistake

The simple thing is how you use the http thread. I know you will be creating an instance of httpconnection class and use it in the thread. Now you'll be starting the thread continuously 3 times. now what happens is either the threads try to start at the same time and create more than one http object simultaniously.

To avoid this use a boolean in the httpconnection class to keep track of number of threads and make the other threads to wait untill the first one finishes the task. or use a seperate function where you creat the httpconnection object and declare it as 'syncronized' keyword.

Another point is remember to close the http object and put = null everytime before you use it next time.

Can you please paste the codeing here which deals with the http connection.

[hemavarthini]

Hi this is a part of http connection coding.So like this i have used 5 to 6 http connections.

public String[] mConnection(String x,String y){
HttpConnection cc;
DataInputStream inn;
byte b1[]=new byte[1064];
try{
cc=(HttpConnection)Connector.open("http://111.151.60.20/sample/sample.jsp?plid="+id);
inn=cc.openDataInputStream();
inn.read(b1);
strvalue=new String(b1).trim();
inn.close();
intLength=strvalue.indexOf("*");
strvalue1=strvalue.substring(0, intLength);

cc.close();
return strvalue1;
}

Now the code it good, there is no bug with the coding you have sent. I think it would be better to add

Code: Select all

cc = null;


and make this function Syncronized

Otherwise the problem would be with the server...

[hemavarthini]

If there 4 connection method like this,then should i add synchronized keyword for the all 4 methods??

[DevelopmentTeam]

yes, you have to some how make sure that there are no 2 connections trying to connect at the same time.

[hemavarthini]

Thanks for the information u have given so far.We will meet soon in some other topic.
Thanx

[DevelopmentTeam]

No problem, but is the bug fixed yet? or please let me know if you can send the code..

[hemavarthini]

No,the problem is not solved yet.I am getting symbian os error still.

1) If you get the error right at the first time itself, then the problem might be with the service provider.
2) If you get it in between, like accessing same url continously then it is with your code.

Now if you think it is your code, just email me your code if you wish. to enquiry@smackall.com I will try my best on it.

I am getting the error only inbetween the game.So as u said it is the case2.
But the same code when i run it in 6230i ,i am not getting any problem.
So I think my code is correct.
The problem may because of symbian os in nokia 6600.
What is your opinion to this?
I am not in a position to send the code.Sorry for saying this.
