I've used Mina and Netty, but now I'm in the market for a lightweight library that may also be used in Android. I prefer Nio or AsyncIo over standard io implementations.
Update 1
The lack of responses really makes me think I should write my own library. Right now I'm using raw NIO and its not a lot of fun.
You might try using some pieces from Jetty as suggested in this email. I really like Jetty because it's small, self contained, and you can use some or all of it flexibly.
Since this seems to be dead on arrival, I'll answer it by saying my custom IO library will be the best.
To answer your question, there is no one size fits all async library. Netty and Mina might be the closest to such a thing, but most projects may still have to contain some pure NIO/ASYNCIO customized solutions.
I maintain you are on the right track. The more experience you have with low-level NIO/ASYNCIO the more you will appreciate and be able to get the most out of the somewhat-less-low-level Netty.

Does anyone knows if there is a good service oriented framework (like Apache Thrift) that supports both C++, java and python with a similar set of features but with lighter requirement?
My main issue with thrift is that it requires boost (on the C++ side) that is a good, but too big, library.
I can think of a few alternatives, although I can't speak for how they compare to Thrift. All of these should have Java, C++, and Python implementations.
Google Protobuf
Apache Avro
Hessian
Of the three, I think Google's Protobuf seems the most promising and documented.

I have a Web Service and I'm trying to add a simple Web User interface with the ability of adding some text and uploading file. what is the simplest and easiest one to use and compatible with Java. I'm using eclipse to develop my application.
I don't need a lot of support I just want it to be easy to use.
I can recommend wicket (http://wicket.apache.org/) you won't have licence restrictions (it's an Apache licence) and it's a time resistent solution: JSF are too complex for simple use cases, and Struts is quite as complicated but a rather old technology. GWT is too complex and time conuming for small projects.
You can naturally use bare Servlets or JSPs if you're really in very simple use cases.

I can't find any documentation for Jagatoo, except for a single PDF in the doc folder. Is there any at all?
Would make it a lot easier to read about the structure, rather than investigating it all.
Read the source code.
Source code really is the best documentation in the absence of adequate documentation. I find that if I really want to wrap my head around a framework or library, the best thing to do is to dedicate an evening (or weekend, depending) to a proper deep dive of the source code. The added benefit is then that you know exactly where missing functionality needs to go if you want to implement it yourself, and better yet, contribute it back to the Open Source community.
PS I presumed you meant that the PDF on this page is the only one you could find.
You could potentially also look at how Xith3D makes use of JAGaToo.

I am looking for an open-source application/tool/technology which can show times of distributed request across distributed system.
I have found some wonderful stuff like AppDynamics, but they are all commercial. I don't need such a wide functionality, but simple request tracking. I have also had a look on this list, but I have some difficulties to understand it.
Could you recommend some solutions if you are experienced with APM?
i don't think that you can do full-featured profiling of distributed request across number of JVM's - AppDynamics from what i can remember understands the EE stuff - like calling DB, EJB, RMI, or remote webservice - however it still works in scope of JVM.
Isn't it suffient in your case just to use java profiler (like yourkit, jprofiler)?
Did you try the free version of AppDynamics. It's called AppDynamics LITE.
You can take a look also to EXTRAHOP free version. Maybe it is good enough for your needs.
Also you can try using a SaaS solutions such as NewRelic or Boundary. They have free accounts that could also be good enough for your needs.
Finally if you want to monitor the performance of any specific JAVA application, you can use http://www.moskito.org/. It's totaly FREE.
you can try 24x7monitoring
https://code.google.com/p/monitor-24x7/
it provides method level monitoring, SQL queries, business transactions...

I am looking for a java port of this file,
Jenkins Hash in C
This looks like one.
Though, by the looks of description on the Wikipedia article you could port it yourself without too much trouble.
Hsieh's hash is even better. I don't know of a java implementation - i'm writing one right now.
At Github there is g414-hash project which includes hash functions you might want to use, including jenkins, murmur, hsieh and cwow. It also has bloom filter implementation for which hashes can be used.
A duck duck go searched reveals this: http://www.java2s.com/Code/Java/Development-Class/JenkinsHash.htm
