java.lang.NoClassDefFoundError

i created a bluetooth application,when i test it in the emulator,it manages to discover other bluetooth devices but when i test it in my pda(Tungsten E2), i get a javax.bluetooth.DiscoveryListener error.When i check the details of the error is says java.lang.NoClassDefFoundError.

Anyone know how to sort this out?

Thankx...Yusra

are you sure that your PDA implements javax.bluetooth.DiscoveryListener? if not, export it with your application !
