I have developed a small Midlet with the SUN J2ME Wireless Toolkit. I want to open the system browser with the platformRequest -method, but cannot compile. Code is:

if (c == openCommand) {
                  platformRequest("http://www.fi");
            }

When trying to compile, I get the error:  javax.microedition.io.ConnectionNotFoundException

In the WTK (2.1) system.config file, I have defined:
# platform request
com.sun.midp.midlet.platformRequestCommand: "C:\Program Files\Opera75\opera.exe"

What is wrong!?

if c and openCommand are strings then you should be using:

if (c.equals(openCommand)) {

if platformRequuest throws an exception you need to handle it:
eg.

try {
   platformRequest("http://www.fi");
}
catch (Exception ex) {
// handle exception
}

Hi,
if the platform cannot handle the URL requested then  it throws the ConnectionNotFoundException so you need to catch it as objects has specified.

Thanks objects,

it is now working on the WTK 2.1 emulator! Just needed to catch the exception.

Wonder how it will work on a real phone, I have heard that most phones cannot handle the platformRequest() -method. Has anyone experience about it?

Hi vmmattil,

>> Wonder how it will work on a real phone...

All MIDP2.0 compliant phones must accept this method. If not, the problem should be corrected by manufacturers.

Some links about the platformRequest() method :
