suggest a java based tool for developing calculations-intense application

Question

We are having a proposal to develop a new application which has intense calculations. Its basically a score card/dash board application where the UI is developed in FLEX.

In the middleware the data will be read from Oracle and the calculations will be done. From the Oracle we will be only reading the data. There will be no write operations to the database.

there are many formulas which I'm not sure where to place.

As of now, the plan is to develop the services using Spring.(Container + Spring_JDBC) and expose them as SOAP based webservices (using Axis).

I've developed applications like above. So, am thinking the same way. Can any one suggest any better approach?

Answer 1

Try GWT. The whole stack will be in Java. GWT is also capable of building rich UI's and you can handle a lot of thing at the client layer itself.

如果打算将密集的计算分派到多个主机上，则可能需要看一下GridGain框架： http : //www.gridgain.com/product.html
