7. Download and install MicroEmulator from CVS (http://www.sourceforge.net/projects/microemulator)
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/microemulator login
When prompted for a password for anonymous, simply press the Enter key
cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/microemulator co -P microemulator
cd microemulator
Edit build.properties file and set the following variables:
    target.app.type = swt
    target.app.type.swt.jar = ../swt-3.1.2/swt.jar
jamvm -cp ../apache-ant-1.6.5/lib/ant-launcher.jar -Dbuild.compiler=jikes -Djikes.class.path=../classpath-0.90/lib/glibj.zip org.apache.tools.ant.launch.Launcher all
cd ..

8. Download and install Microemu-maemo from CVS (http://www.sourceforge.net/projects/microemulator)
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/microemulator login

cd ..

9. And finally run the SimpleDemo MIDlet
jamvm -cp swt-3.1.2/swt.jar:microemulator/target/me-app.jar:microemu-maemo/target/microemu-maemo.jar:microemulator/target/simpledemo.jar -Djava.library.path=swt-3.1.2 org.microemu.maemo.Main com.barteo.midp.examples.simpledemo.SimpleDemo

To run own MIDlets replace:
- microemulator/target/simpledemo.jar with own MIDlet jar
