J2ME modifying midlet AppProperty

[NitinSawant]

Hello,
I'm working with Netbeans Mobility Pack (Sun java wireless toolkit 2.5),
I've created small midlet,
I'm adding "MYID" custom property(Attrib ute) to the midlet,
I know how to retrieve the property,

midlet.getAppProperty("MYID");

but i don't know how to change the custom App Property as there is no setAppProperty( ) method,

pls help me about the issue,


regards,
Nitin Sawant
