Persistencia Java ME

Carlos_Alberto_Solla · Dezembro 14, 2009, 11:52am

Olá

    Sou novato em java, e estou precisando montar um programa em Java ME que ira rodar em um celular Motorala Q, no qual preciso persistir dados em 3 tabelas. Qual framework devo utilizar para facilitar o trabalho? Estou tentando utilizar o Floggy com Eclipse Galileu e MTJ 1.1, mas está dando um erro e não consigo resolver

Verifique as versões suportadas.
