Question

I am stuck creating a socket connection between blackberry client and java server. I need simple sample code which extends the socket API example from blackberry sample code.

We have a server that communicates with android systems and we need it to work with blackberry client as well.

Answer 1

Sorry for being late. And I am posting my comment here because of comment length. _screen.isDirectTCP() isn’t an API method, so I am not sure what does this method return. But from the method name/signature I think this method is only used for checking whether Direct TCP connectivity is available or not on the device. Depending on the result, the application will append the connection parameter such as “;deviceside=….”.

From the Network Transport article,

If you do not want your application to rely on the default connection
types described in the previous sections, explicitly state the
desired connection type by adding the “deviceside=” parameter to the
destination URL. If an application appends “;deviceside=true” to the
destination URL, then only a direct HTTP or TCP connection is
attempted. The application does not attempt to connect to the network
using the BlackBerry MDS. Alternatively, if an application appends
“;deviceside=false” to the destination URL, then the application only
attempts to connect to the network using the BlackBerry MDS. The
application does not attempt to connect to the network using a public
IP gateway.

Also please have a look at this link, What Is – Different ways to make an HTTP or socket connection.
