Hi,

 From the creation proposal and my article on OFMP I remember, some
Services mentioned there.

Do some of those exist already?
Especially the Date/Time and Currency Services.

Yes both exist in current code base, thought they could be extended.
Date service is about business date management. We have a Calendar
Service that take a currency calendar as input and
http://objectlabkit.sourceforge.net/ as underlying engine.

Hi,

I recap that JQuantLib http://www.jquantlib.org/ is being actively
developed.

We are planning to have european option valuation via Black and Scholes
entering in unit test phase till end of april. At the moment, I'm working
on the core object model which supports all intruments and pricing engines
implemented by QuantLib/C++

In particular, QuantLib(C++) has support for currency calendar and we could
simply implement these classes in JQuantLib(Java) as we already have all
the necessary support classes.

Thanks


Sounds interesting.
What types of support classes do you have for both the Time/Date aspect off this and the actual Money/Currency?

I spoke at QCon with several other Spec Leads of the JCP including Rod Johnson (Spring) One of them leads JSR-310 (Date/Time) and also is the lead architect of JodaTime (one of the 2 libraries ObjectLabKit already supports)

So if your code also is compatible with what IS provided by Java itself on Date/Time or shall be from Java 7 or 8 onwards (basically a combination of Joda and java.util.Date,... but more in style and design of Joda's current API) that should be fine.
If you intend to use something homegrown and proprietary, that may not be favorable for OFMP

And of course, Eclipse has its own sanitary requirements, where accepted standards like Apache, Spring or JSRs are not a problem, but additional code often can be. Currency and Money are therefore also better using an existing JSR proven to work (including Spring, I just did a complete International Stock Market demo on QCon)
