Here is what our users say about us
The developers at BlackBeltFactory.com use JRebel and although I probably could have gotten it for free from the ZT guys, I wanted to pay for this fantastic product.
We’ve had some real OutOfMemory problems in our production environment for quite some time. Once I got XRebel up and running I noticed that our most used webapplication uses around 15MB/User session. By tuning a few JSF parameters I got the average user session from 15MB to 0,5MB.
Since migrating to IBM WAS 7.0, we've had trouble with replacing HotCode - we're now using JRebel for uninterrupted development and it's working fine :)
It used to take 5 mins to rebuild and restart the server - now we see changes pretty much instantaneously. I saw the value right away.
Con JRebel, salvar un archivo en el IDE y ver mis cambios inmediatamente en la pagina sin tener que volver a hacer "deploy", no tiene precio.
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.
It not only takes me at least 2 minutes to redeploy, but it adds another 5 minutes to get back in the zone and I still have to bring the application back to the state where I was developing. This alone is at least 10 minutes lost for a minor change. JRebel deserves every single cent of its selling price.
Manual redeploys were drawing us crazy, tired and bored. Now development is fun again.
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.
JRebel seems to be the only cost effective way to accelerate the compilation and startup of our projects, consisting of several EAR artifacts deployed on a JBoss App Server. We have been using it for a year, and my development team is very pleased with it.
Since introducing JRebel to our Java development teams, we have not only seen a 30% increase productivity, but also a marked decrease in service requests due to software faults. Our teams can now focus 100% of their attention on development without being hindered by the J2EE cycle Build and Redeploy steps.
Over the last 265 days JRebel prevented at least 1,209 redeploys/restarts saving me about 49 hours.
