Our Java application runs too slow on one machine. Is there a pure Java clustering software package that enables our software to run on a network of machines?

See also Gaia at http://www.TheMindElectric.com. Most of what you see there will be about SOAP and XML but I think Gaia can be used more generally.
What's your architecture like? Are these web servers or maybe stateless app servers? If so, you could set up two identical machines and use a load-balancing scheme to divide users between the machines. We use Local Director hardware to do this, but there are many hardware and software choices.
It gets a lot trickier if your servers are stateful. I'm on a project now using Forte to distribute services across two machines because some stateful services cannot be duplicated on two machines. The inter-machine calls are far from free!

A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
