We are newbies in Linux & having average knowlegde of java, j2me...

We have installed sun java in the linux box..then comm.jar api.
the deployment of the .so & java.comm jar is done as per requirement

our application is based on the following code:

we have complied java files...then we have written the shell file for running the java class file.

--------------------------------------------------------------------------------
//DemoSms.java
public class DemoSms
{
public static void main(String args[])
{
SMSClient sc = new SMSClient(1);
sc.sendMessage("MyCellNo","Hello");
}

}
//ends here


#shell file

JAVA_HOME=/opt/jdk1.5.0_12
CLASSPATH=/opt/sms:$JAVA_HOME/jre/lib/comm.jar

$JAVA_HOME/bin/java -cp $CLASSPATH DemoSms

#shell file ends here

As we are newbies we are not able to trace where the actual problem is...
We have used this modem in windows env and it runs perfectly..

We have tried confirguring minicom also to try to send sms but we have failed in doing so..
We have already put around 20 hours trying to find the error but with no use..

Please help!!!..
