The Jakarta-ORO Java classes are a set of text-processing Java classes
that provide Perl5 compatible regular expressions, AWK-like regular
expressions, glob expressions, and utility classes for performing
substitutions, splits, filtering filenames, etc. This library is
the successor to the OROMatcher, AwkTools, PerlTools, and TextTools
libraries from ORO, Inc. (www.oroinc.com). They have been donated to
the Jakarta Project by Daniel Savarese (www.savarese.org), the
copyright holder of the ORO libraries.

This is a pure-Java implementation of Berkeley DB by SleepyCat (now
Oracle). Java-1.7 is required for building. From the
"Berkeley DB JE was designed from the ground up in Java. It takes full
advantage of the Java environment. The Berkeley DB JE API provides a
Java Collections-style interface, as well as a programmatic interface
similar to the Berkeley DB API.
Berkeley DB JE is different from all other Java databases available
today. Berkeley DB JE is not a relational engine built in Java. It
is a Berkeley DB-style embedded store, with an interface designed
for programmers, not DBAs. Berkeley DB JE's architecture employs a
log-based, no-overwrite storage system, enabling high concurrency and
speed while providing ACID transactions and record-level locking.
Berkeley DB JE efficiently caches most commonly used data in memory,
without exceeding application-specified limits. In this way Berkeley
DB JE works with an application to use available JVM resources while
providing access to very large data sets.
The Berkeley DB JE architecture provides an underlying storage layer
for any Java application requiring high performance, transactional
integrity and recoverability."

The JavaHelp system is an online help system that developers can use to
add online help to their Java platform applications. The JavaHelp system
is both a JCP specification (JSR 97) and a reference implementation of
that specification. The JavaHelp system open source project includes the
source to the reference implementation.
