R is powerful for statistical computing, however, it has its own shortcomings such as difficult to deal with large data, which is one of the motivations of Renjin. I haven't tested it, as described on its page:
Renjin seeks to be a pure Java implementation of the R Language for Statistical Computing.

Project Goals: Build an implementation of R that:
Runs purely in the JVM, including Google App Engine
Fully compatible with (pure) R packages written for R 2.10.x
Compiles elligible, heavily-used closures to JVM byte code
Enables R-language objects to be backed by datastores other than memory

If you happen to use Java and want to test it, download the code @ http://code.google.com/p/renjin/

This tool can replicate and price any non path-dependent, continuous piecewise linear payoff function on a stock. You can use the tool to price and value option positions and simple structured products on a stock.

The Financial Engineering tool automatically replicates and prices a given continuous piecewise linear payoff function. So far the tool can only handle payoffs on a stock, where the payoff is denominated in the same currency as the stock.

Many people know QuantLib, which is a free/open-source library for quantitative finance for modeling, trading, and risk management in real-life written in C++, for those people prefer Java language, they have to read & understand C++ codes and transfer them to Java code. JQuantLib is aiming at these Java-fans group,

JQuantLib is a free, open-source, comprehensive framework for quantitative finance, written in Java. It provides "quants" and Java application developers several mathematical and statistical tools needed for the valuation of financial instruments, among other features.
