Aorta is a load-balancing clustered P2P application. It executes Tasklets (which have the ability to split themselves into sub tasks that can be executed in pararell). A typical cluster contains of a LAN with 1-256 computers, each one running aorta. A Tasklet can be of any type ranging from encoding MP3s, Genomic DNA Alignment, or simply to rendering Web pages for high speed/heavily loaded Web sites. You can make functions calls to C/C++, applications like Matlab, etc.
jUDO (java Universal Data Objects) speeds up development/maintainence and removes database-vendor dependency for applications using databases. You should use jUDO whenever you don't want to use EJBs. You don't write any database code; you only have to specify the container classes and the interfaces for the models, and then jUDO creates the implementation for you runtime (no source is generated). It derives all info needed from your interfaces method names that follows name-pattern rules. In case you need some special access method, you either add a plugin for this or simply go directly against the database. jUDO is not as configurable and advanced as other much more professional software like Castor, Hibernate, etc., but since jUDO derives the database from your code, there is never a mismatch between code and database.
