Derby and Java ME
John Embretsen of Sun's Java DB team has just posted a thorough wiki page on using Derby on Java ME platforms. He also shows how to test Derby with IBM's J9 and Sun's phoneME implementations. The tips and tricks section has some good pointers. Embretsen's wiki is a good place to start. Another good place is Mayuresh Nirhali's weblog on "JavaDB on JavaME."
