jSieve is a Java implementation of the Sieve mail filtering language defined by RFC 3028. Sieve is an extensible mail filtering language. Its limited expressiveness (no loops or variables and no tests with side effects) allows user created scripts to be run safely on email servers. Sieve is targeted at the final delivery phase (where an incoming email is transferred to a user's mailbox). jSieve is implemented as a language processor that can be plugged into any Internet mail application to add Sieve support.
ProteomeCommons.org IO Framework is a proper Java framework for handling spectra and peak lists. The framework can read and write to a number of different spectra and peak list formats, and it provides a simple, intuitive Java object model for working with spectra or peak lists. All classes support two methods of handling peak list and spectrum data: in-memory or stream. The goal of this framework is to support all the popular MS and MSMS data formats, and to eliminate any time or effort involved in figuring out how to read and write peak list or spectrum files.
