Test Java apps as you code

Every time a developer tests a code change it takes minutes to build and deploy the application. JRebel keeps the app server running at all times, so testing is instantaneous and interactive.

Why use JRebel?

Why Users Love JRebel

I heard about JRebel from my colleague who highly recommended using it. After trying it out a couple of times, it made perfect sense to me, and I haven't looked back since. Great product.

Given the nominal cost of JRebel and the huge amounts of time it saves, I would not consider developing Java EE applications without it.

Jrebel is pretty much well known but I never really considered trying & buying it because most of my projects were not so complex. Now I have a much bigger project and applying code changes becomes more difficult so I decided to give JRebel a try. So far, trial version worked perfectly.

For the price, and for how easy it is to get installed and running in a developers’ environment, using JRebel is pretty close to a no-brainer.

JRebel has transformed a nightmarish 10-minute modify, compile and debug cycle to a matter of seconds. Thanks for giving me back my sanity.

Working with JBoss, Seam, JSF and the Eclipse JBoss Tools...It's very painful. I had read about JRebel a couple of times on theserverside.com and javalobby and decided to give it a try. It works great.

Alterar método, adicionar atributos, criar classes, restart servidor, isso era um ritual a cada hora do meu trabalho. Com JRebel posso alterar qualquer código java que já é refletido na aplicação em funcionamento. Muito bom.

I'm afraid our developers might go for a strike if we say to them, ‘Hey, we're not going to use JRebel anymore.

JRebel saves a lot of frustration from dealing with JSF, JPA and Tomcat. One big thing is I don't need to start Tomcat every time to see my code!
