Duas agendas, uma para compromissos pessoais e outra para
compromissos profissionais. Deve haver uma escolha no Midlet
para qual agenda o usuário deseja acessar
sim…nao entendi…vc ta usnado o netbeans?
se sim entao vc tem que clicar nas propriedades do projeto e definir outra Midlet e assim por diante…ou fazer uma midlet que chame as outras…tipo uma aplicação que tenha menu para “subaplicações”…é isso?
se nao…explica melhor essa sua duvida…espero ter ajudado

.Agora tenho que fazer duas agendas, uma para compromissos pessoais e outra para
compromissos profissionais. Deve haver uma escolha no Midlet
para qual agenda o usuário deseja acessar. Um recurso para ler uma agenda localizada em um banco de
dados no servidor, e inserir os dados desta agenda no record
store.Inserir um recurso para remover as agendas

bom meu caro…pra começar…eu nao usaria o RecordStore assim no seco…usaria o floggy…bem mais simples de buscar…salvar…etc…segundo:
vc pode declarar mo seu projeto qauntas midlets quiser…vc so tem que apontar la na sua propriedades do projeto quem é midlet e quem nao…que ai o emulador faz isso pra ti…vc ta usando o netbeans?
