How do I create the .app file to package MIDlet packaged as a jar in a sis
file. I need to package it as a sis file so I can add additional aif and
resource files and to specify my own UID.

Theoretically this should be possible with a tool called appbuilder but I
can't find it anywhere.

Also all the samples Java that come with the sdk have their own aif , app
and txt files created but HOW?
