========== Initial commands ==============

The commands in this file are set up for you hello.java file.

To reuse it for other files, change the Hello to whatever you have named your file/class.

Compile command for the *.java file:

javac -target 1.6 -bootclasspath %MIDP_HOME%\classes Hello.java

After you compile you, the *.class file is generated.

Then issue the preverify command:

preverify -cldc -classpath %MIDP_HOME%\classes;. -d . Hello

Issue the run command:

midp -classpath . Hello

Command to create the jar file from the manifest

jar -cvfm HelloMIDlet.jar HelloMIDlet.jad *.class

Issue this to show the contents of the jar file

jar -tvf HelloMIDlet.jar

To run the JAD file

midp -classpath . -Xdescriptor HelloMIDlet.jad

========== Java ME commands ==============

javac -target 1.6 -bootclasspath %MIDP_HOME%\classes Hello.java

preverify - cldc - classpath %MIDP_HOME%\classes;. -d Hello
