Hello,
Is there way to communicate in J2ME like RMI in J2SE ?
If not what would be best way to do similar kind of job ?
I have an desktop application that uses RMI with an applet. I want to port that application( write a new one which does similar functionality) for micro devices like cell phone and PDA.
Any ideas would be realy helpfull.
thanks in advance,
chini

The current J2ME specification for CLDC 1.0 specifies a generic connection framework that supports the following interface types:
o Basic serial I/O
o Datagram-oriented communication
o Circuit-oriented communication e.g. TCP
o HTTP connections
The CLDC specification offers the connection framework but does not define any network protocols per say. It is up to the J2ME profiles to define the protocols for a specific device category. For MIDP 1.0, only HTTP connection is supported.
Connections are created using the static method in a system class called Connector. So for MIDP right now, the line of code to open a HTTP connection will be:
Connector.open("http://www.MyWebServer.com:8080/MyApp.txt");
So we would suggest that you write a new application that has the same functionality but only using HTTP connections for the device to communicate with the web server rather than use RMI as CLDC/MIDP does not support RMI.
HTH.
