The 2.2a version of the ACE ORB (TAO), pronounced "dow", is a CORBA V3.0 compliant, C++, object request broker. It is a second generation ORB developed with a highly extensible architecture as a result of its use of what might be termed a pattern framework, more commonly known as the ACE library. (ACE is an acronym for ADAPTIVE Communication Environment, ADAPTIVE is another acronym and stands for A Dynamically Assembled Protocol, Transformation And Validation Environment!).

The JServer Java virtual machine (JVM) is a complete, Java 2-compliant Java execution environment. It runs in the same process space and address space as the RDBMS kernel, sharing its memory heaps and directly accessing its relational data. This design optimizes memory use and increases throughput.The JServer JVM provides a run-time environment for Java objects. It fully supports Java data structures, method dispatch, exception handling, and language-level threads. It also supports all the core Java class libraries including java.lang, java.io, java.net, java.math, and java.util. Figure 1-3 shows its main components.
