Java framework for distributed system

Question

I am looking for a library (or a combination of libraries) to build a java distributed system, made of several applications exchanging data through several pairwise connections (no mapreduce). For the moment I did an expolration of existing libraries and I could only discard what I'v found. Here are my requirements:

• Easy discovery of systems at runtime (possibly through a central server/directory)
• Lightweight and low latency messages (no CORBA, RMI, SOAP,. etc.)
• Decentralized communications (no LINDA like)
• Easy enough to use and learn (no JXTA)
• Compatible with GPL license (so GPL, BSD, etc.)

Do you have any suggestion ? Thanks in advance

Answer 1

Are you familiar with JGroups ? You could use it to design your own architecture. They provide easy-to-use multicast abstraction.

Answer 2

I'm a big fan of JGroups, but I recently discovered hazelcast and will probably give it a try. It might be what you're looking for.

Answer 3

你可能想看看Terracotta（ http://www.terracotta.org/ ）

Answer 4

I think Apache River (formerly Jini) should at least be mentioned. It never received too much attention, probably also because it had (don't know if it still has) a rather steep learning curve. Anyhow, it is under active development:

如果你喜欢多智能体范例，你可以看一下Jade http://jade.tilab.com/

Answer 6

JBoss ，好吧，好吧，它不是一个框架，但它们有很多项目听起来就像你想要的那样。
