Tapestry and JMeter

Tue, 16 Nov 2010 00:00:00 +0000

I was recently tasked with setting up some load tests for our Tapestry (4.1.6) web application. I chose to use Apache JMeter because it is open-source and is flexible enough to do what we needed, and doesn’t cost $12,000/month like some load testing tools.

I set up an HTTP Proxy Manager to record a simple navigation through the site and reconfigured my browser to use the proxy. The proxy recorded the requests without a hitch.

Tapestry: UpdateComponents, Eventlistener and Script files

Sat, 10 Apr 2010 00:00:00 +0000

This week I encountered an interesting issue in Tapestry when I tried to dynamically load a component using Tapestry’s built-in EventListener functionality. The component in question had a .script file associated with it, which Tapestry loaded dynamically, but the JavaScript functions in the .script file were “not found” when I tried to execute them.

After a bit of digging around, a colleague of mine noticed that Tapestry was loading the .script file using an eval() statement instead of inserting the script into the DOM.

JRebel and Tapestry working together

Fri, 26 Feb 2010 00:00:00 +0000

I’ve recently started trialling JRebel at work. JRebel is a piece of software that hot-swaps your code so that changes made in your IDE are reflected in your application server without requiring a restart.

The benefits of this idea are fairly obvious. I no longer have to wait 1 - 2 minutes for JBoss to restart each time I correct a spelling mistake etc. The time saved by not restarting probably make the product worth the $US149 licensing fee.
