I learned two things during the last couple of days: first, that an EeePC is not the most comfortable way to work on more than a simple hack, and second, that ESME no longer works on Java 5. The problem seems to be that the derby driver has classes with version 50.0, which means working only on Java 6. Not sure if this is critical, but I thought I'd mention it in view of the fact that Mac users have long struggled with outdated Java versions.
