Is there any way to detect the available network and connect directly in blackberry?? I have tried the following link http://supportforums.blackberry.com/t5/Java-Development/What-Is-Network-API-alternative-for-legacy-OS/ta-p/614822 but getting the following error

I selected lines and pressed CTRL+K to make it to look a code. - Adil Soomro
The legacy API is intended for pre 5.0 devices. Yet it must compile, and i've used it without problems. If you are using 5.0+, use the Network API and TransportInfo stuff. - Mister Smith
Is Blackberry 5.0.0.jar compatible with j2me polish??? - happy

This is best way to getting available connection and run project smoothly

in following link i specified two classes

1)HttpConnectionFactory 2)HttpConnectionFactoryException

click here to see the above classes

copy these two classes in to your project and

write following code (already specified into the link) this will take care to checking all available connections in some order 1)WIFI 2)BIS 3)BES 4)TCP 5)WAP which is first available then it will stop checking and take that connection to run project

HttpConnectionFactory factory = new HttpConnectionFactory(0);
        Httpconnection httpConnection = factory.getHttpConnection(url);
            if(httpConnection.getResponseCode()==HttpConnection.HTTP_OK){
//some of the connection in available
}else{
//no connection available
}

if i am wrong please ignore this

If this Link and take the HttpConnection.java and try it. If it is not working then see the "peter_strange" post on that same link. There he provided links that will help you;
