Do not announce products going into the central repository. This is
not a free advertising forum. It's a total abuse of this list.

ObjectLab is pleased to announce the release 1.0.1 in Maven
Repository of
Objectlab Kit for Java 1.5
Open source Date Calculators for Business and Finance.
http://objectlabkit.sourceforge.net
The ObjectLab Kit is released under the business friendly Apache
License
v2.0.
It is available immediately for download via SourceForge or the Maven
Central
Repository (both Maven 1 and Maven 2). The homepage has some very
quick examples.
The Kit provides Date Calculators and comes in two flavours:
- one based on pure JDK (1.5)
- one based on the Joda-time library (1.3+, jdk 1.5)
This library is now live in a major UK & international Bank (in
their Credit
Derivatives department). The library is small, lightweight and
thread-safe.
The DateCalculator implementation is useful to any business; the
other two
interfaces are more specific to the financial industry.
The most common function of a lot of banking or business
applications is the
handling of holidays and weekends, a set of standard rules are
implemented
to
deal with days falling on a holiday. The library does not attempt
to guess
the 'holidays', most business will have an official list anyway, but
concentrate on the date manipulation and calculations.
What does it provide? Implementation of 3 interfaces
- DateCalculator for all date calculation and handling of weekends or
holidays.
The supported algorithms are: Do Nothing, Move Forward, Move Backward,
Modified Following and Modified Preceeding. The Calculators are
immutable
once created but they can be easily composed to take into account
multiple
sets of holidays. The library also supports the calculation of
generic tenor
dates (Spot, 1D, 1W, 2M, 3Y, etc)
- PeriodCountCalculator for calculating differences between two
dates in
days,
months or years according to some financial algorithms: ACT/360,
ACT/365,
ACT/ACT, CONV/30-360, CONV/30-365_ISDA, CONV/30-360_ISMA
- IMMDateCalculator, to calculate the International Money Market dates
(IMM Dates are 3rd Wednesday of March/June/Sept/Dec)
This kit is one of the first steps in pushing the Open Source
movement up
"the stack" towards business functionalities in the financial
industry.
ObjectLab is not new to the open-source community having used
numerous OS
projects, participated in a few and sponsoring QALab
(http://qalab.sourceforge.net), a tool that keep tracks over-time
of the
static analysis results from FindBugs, Checkstyle, PMD, Cobertura etc.
We would like to thanks our friends and colleagues at XXXX for
their help,
reviews and suggestions.
Sorry for the long email...
Feel free to pass on to people who may be interested.
Enjoy!!
Benoit Xhenseval and Marcin Jekot
