I am trying to record events for Vaadin application using Loadrunner web protocol. However, when I replay the recorded script, the request that goes in is different from what is being recorded. I am not sure on what basis these values change and I am not getting expected results/response due to the change in request. I am new to Vaadin app, any help on this would be greatly appreciated. Thanks in advance.

I want to implement Google type searching in my iPhone application using Auto Complete Text field, like when user enters some characters it should give hints of related data coming from server using Soap web services.this service return whole data but i want it search as per character. I have searched lot. I am new one in iPhone development. Please any one help me and provide some useful links or tutorials. I got stuck in it.
I am using chart-kick to generate graphs in my Ruby on Rails application. I am able to display the charts without any problem. The issue is I am in need to refresh the page which has the graph each time the data is added to see the updated graph. How do I make sure that the graph alone reloads everytime I update new data in my database? Is that possible?
Note: Highcharts is not an option. I am giving this to a commercial website and they can't afford Highcharts.
I ended up using Chart.js and using Ajax requests to poll the database and update the graph for its changes. I was not successfull in implementing Websockets.
To achieve what you want, you need a bidirectional communication between your server and your client.
I will suggest you to use websockets, it suffers from not being supported by all browsers but as fallback you can use polling the server for new results (if you care enough for a fallback). To check the current support status check this page.
Follow this example on websocket-rails gem to get started.
I would use something like pusher its for doing exactly what you need.
Use turbolinks for reload graph
I have added the two lines of code to my project as described in this blog post.
However, as nothing different happens in the app itself, is there a way to test this behaviour and check it is working as expected? Is there a profile in instruments? Is there something I can print to the log in Xcode when a response is cached/cached response is used?
It just seems so simple to implement, I want to make sure it is actually having an effect on my app and that I won't have to implement a caching system myself.
Many thanks,
Sam
go offline right after you got the page and then reload the web view. the caching should take effect and the page should load I'd think
You can make sure so by analyzing HTTP traffic through a third party software like Charles.
Whenever app will make a request, HTTP Analyzer will pick the request made. If it is using cache, then same will be reflected in it.
(Check the contents of response to confirm the same)
Can anyone please recommend any good Load Testing software?
I have a website which updates scores every minute via ajax calls and need a load testing software which supports ajax calls (javascript) too!
This is a pretty broad question that depends greatly on exactly what you want to test and how you define "good" software. Many people will say you can't load test AJAX based sites using HTTP-simulation tools. We do it every day, so I can tell you that isn't true. However, the difficulty of the task varies greatly depending on the testing software you choose and the complexity of the site and scenarios you are testing.
My recommendation is to pick a few tools within your price range and evaluate how well they work for your particular scenario. If they have good support, you should contact them with any difficulties. If they can't get you going in short order, move on to the next product.
(Disclaimer: I work for Web Performance - our Load Tester product handles most AJAX scenarios just fine - which may be why we're on the first google page for "ajax load testing").
Ajax is just an HTTP call, so you have many options.
I can recommend WebLOAD.
Works well with Ajax. The script is written in JavaScript, which is a plus.
Although I cant recommend an AJAX load testing utility I can however recommend an alternative to normal AJAX calls to me it sounds like what you need is APE (Ajax Push Engine).
So instead if your application spawn repeatedly contacting the server
Your App -> Do you have a message for me server?..
Server -> No..
repeat X 10 Ajax Calls until Server -> Yes!
What APE does it pushes the data/information directly to your users browser without
the application contacting the server. Think of it this way, the server "shouts" a message and your web apps then receive this message and interprets it. This concepts is known as long polling.
APE is pretty darn fast and not that difficult to implement.
Heres a link to the APE project - http://ape-project.org
Theres a few guys that have some excellent examples available on the Internet,
heres a link to an interesting one which uses APE to create an SMS gateway.

I'm modifying a piece of JavaScript code that uses XMPP + XIFF flash object to communication with MSN/Yahoo/GTalk via Jabber.
The requirement of the web site is to enable page refreshes.
However, the problem is the current implementation of XIFF does not allow saving and restoring of connection, but requires a new login every time, which is time consuming.
I wasn't able to find any reference to such a solution.
Does anyone know if:
This is at all possible with the XIFF open source code?
Any reference to such solution - might consider JavaScript solution as well.
Thank you very much!

I do not believe this is possible. Standard work-arounds are to either have a separate window, or some form of IFRAME which acts as such.
