As people have suggested on this list, in order to write a haskell program
you need to develop a mathematical model which requires some serious up
front thinking. Writing java code on the other hand is more about coding
and then re-factoring. 'Thinking is discouraged (agile), as the design
is more about how you organize your objects for the illusive reuse and
future requirements than anything else. The approach make sense if you
consider design as an excersize in object organization as you would have
better idea on the object organization (aka design) as you plow through the
code.
On the other hand if you have a mathematical idea, then a language like java
doesn't give you the abstraction tools necessary to implement it as well as
a language like Haskell. But if you don't have a model, then java's
approach may be more natural (as is evenident by its popularity)
It seems to me that the two can work side by side if you model your
application in Service Oriented Architecture. I think the boundries of
the services should be thought of as langauges rather than api (function
calls). Two different examples that comes to mind are the SQL and Google
Chart. A Java programmer doesn't care about the SQL Server implementation,
but it depends on its query langauge to create the tables, populate them,
and issue rather complicated queries on them. Google Chart is
interesting in that it porvideds a language in a URL to implement a service
that has been traditionally considered as library. I would think if you can
defines such services in your application then you can define a langaugage
and mathematical model around it to implement the service in Haskell.

I know Haskell, they know Java, and it
would be nice if we could share code and
work. The idea of the api, or maybe dbus,
seems OK. It just would be easier if we
could join everything in a single piece,
but it is no big deal.

Why do you want to mix haskall and Java in one VM? If there are
functionality within your code that is better implemented in haskell, then
why not make that into a service (run it as haskell) with some api that
Java code can use.

Hi,
I use Haskell, and my friends at
work use Java. Do you think it
could be a good idea to use Haskell
with Java, so I could understand
and cooperate with them? Is there a
a Haskell to Java compiler that's
already ready to use?
Thanks,
Maurício
