I have a application that is deployed on tomcat container.
I'm running the jmeter load (x threads with HttpRequests).
then I'm looking on TPS, latencies, cpu, and memory (through jmx).
I'm looking for a automatic way to do all this, and may be better.
Any good references, blogs, articles, maybe some github sources is appresiated
You'd really need to be more specific about what you would like to automate, running the test, analyzing the results, monitoring your AUT or?
That said, you could try this: https://github.com/oliverlloyd/jmeter-ec2. This will automate test execution using remote hosts which can be useful to some people in some scenarios.
Ehm so are you searching for what exactly? I was using JProfiler and it was very efficient for me. I recorded measurement data from my app which i could analyze on the fly and afterwards as well. But i'm not sure if this is what you need. "Automatic stress test". Maybe you could run a bunch of Selenium tests while running JProfiler? Will you use commercial or do you prefer 'free' (sorry for the term) tools?
Have fun anyway :)

For my software engineering class project, my group and I are developing and Android application. We have decided the best way to keep the code managed is via the subversion control plugin for Eclipse. However, none of us have actually managed our own repository. We have always been given it from our professors. Where can I find a free repository to upload our code? Thanks!
There are tons of places that offer free repositories. Here are few:
https://www.assembla.com/subversion/
http://www.projectlocker.com/
http://riouxsvn.com/
http://beanstalkapp.com/
I would definitely recommend Assembla. The first time I used it I was in a similar situation as you. Didn't know what to choose, overwhelmed by all the choices. I went with Assembla and having used Assembla extensively since, I'm quite sure it will satisfy your needs. Has great features for team working also, and being robust, free and easy to manage it's worth a try.

I'm writing the code to access and download data from some web sites using HTMLUnit.
I was wondering whether a tool that could help me exists. I think maybe to a visual tool, something that lets you express the path you want to follow on the web sites visually and generates the Java code.
I'd like something for HTMLUnit, but I'm open to other solutions.
Writing screen-scraping code gets very repetitive :(
I used to work at screen-scraper. Not sure if it's quite what you're looking for, but it's definitely a powerful tool for building web-scraping scripts.
Not exactly visual tools, but maybe you could use something like JMeter or The Grinder for recording navigation scripts of web pages. They surely are easier to use than writing all the input requests by hand in HTMLUnit.
There is only one tool that does exactly this - and does it very very well - but it's highly expensive, since their technology is amazing. Some of the biggest companies uses this. I think you might be able to get a free trail, if you want to try it out. http://kapowsoftware.com/

I have made a couple dozens of tests for a legacy system I was handed over.
They generally test/describe some high level feature of the system, and I generally include in the test file itself a little comment about that feature. In this way, I both have a regression test suite and I'm compiling knowledge of the system in a single place, so others in the future don't have to lose all the time I lost trying to understand the (up to now) undocumented system.
Now, I was looking for some tool that would allow me to organize and see the high level features in a simpler way than having to look up to the test files. If it allowed a tag system, even better.
I have heard of Fitnesse but it doesn't look to fit really in what I'm looking for. I'm not looking for a tool to bridge the communication between the client and developers.
This project is coded in Java.
Thanks
If you moved the documentation from the unit tests to the classes you are testing, you could use either standard JavaDoc or doxygen.

I want to automate our field case analysis.
We sometimes get HPROF files from crashes of our product in production, and look for "typical" problems we know of. Examples:
specific threads creating problems
specific classes filling up the heap
etc.
Currently the HPROF analysis is done manually.
I want to automate that.
Does anyone know of a good Java profiler who allows that? I know Yourkit and JProfiler quite well, and am unaware of such features.
Thank you!
You can find something in VisualVM. It integrates the OQL scripting engine and allows you to persist your own queries so you can easily run them against various heap dumps. However, it is not yet ready for headless analysis.
The OQL implementation in VisualVM is based on the one you can find in jhat and it means that it is javascript based - in addition to "standard" OQL queries it allows you to use plain javascript thus increasing the flexibility many times.
There are few examples of the javascript analysis bundled with VisualVM or you can use the user mailing list to get help.
Cheers!

For purely experimental reasons, and to learn about monitoring applications, looking for something with the following criteria:
written in Java
web application, runnable in a web container (tomcat). not using EJBs/JMS.
open-source
somewhat resource-intensive
using MySQL for DB
makes good use of logs (that is, writes to logs often and descriptively)
works fairly simple in EC2, i guess - what kinds of problem could be there? maybe usage of many ports?
The intention here is to be able to send it http query (or soap) requests and be able to significantly load it. Looking for some fresh ideas.
Thanks!
AppFuse is a Java web stack that meets all of these requirements (I don't know what you mean by resource-intensive, but you could always add your own functionality that is CPU-intensive, or I/O intensive, or whatever - or just put load on it).
Here is a link to the quick start guide.
Actually, since it supports multiple web frameworks (Spring MVC, Struts, Wicket, etc), one use case for your performance testing could involve testing with each one to compare different types of functionality.
