I'm thinking of using java for a palm application. Do you know if you can simply beam a document to a palm, then prevent this document from being beamed to another palm, then have the document destroyed after a day? I haven't read anything on java that addresses creating non-beamable 'documents'
J2ME doesn't provide that sort of integration with PalmOS. You would need to use PalmOS directly. Have you had a look at IBM's WebSphere Device Developer (http://www-3.ibm.com/software/wireless/wsdd/)? Last time I used it, you could access the PalmOS API. So, it should be possible to write a Java application and use the PalmOS APIs for that sort of thing.
