Hi all,

Does anyone have experience to test J2ME application with TTCN-3? I wonder if
I can bundle the ttcn-3 testing tools up with a test MIDlet and run the tests
suites on the mobile emulator. I did one experiment in which I tried to test
one MIDlet application with ttcn-3 testing tools without the support of the
mobile emulator. However, I got "java.lang.UnsatisfiedLinkError: getProperty0"
problem although I am sure I imported all the jar archives (javax.* and
com.sun.*) in the ttcn-3 class path.

Here are all the classes imported in my midlet application:
import java.util.Vector;
import java.util.Calendar;
import java.util.Date;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
import javax.microedition.io.Connector;
import javax.microedition.io.HttpConnection;

The following is the error occured in the ttcn-3 testing tools after I loaded
the midlet application into the testing tools.
18:21:44.392 : starting testcase 'MyTestcase'
18:21:44.502 : component `component1' is mtc

Thanks for any kind of suggestions
