![]() Choose your web module, click Edit and disable auto-reloading by unchecking the checkbox > OK. In the configuration page, go to Modules tab. After that, in the Servers tab, double-click your server. ![]() Add your web project to your new server.Choose your newly created Runtime in the Server Runtime Environment dropdown. Browse to your Tomcat installation directory, then choose the dcevm as JRE. Create a Server Runtime that use your new JRE: Go to Windows>Preferences >Server >Runtime Environment >Expand Apache node and choose your Tomcat version of your choice then click Next.Click Directory and browse to your dcevm extracted location. Setup a runtime for this new JRE in your Eclipse by going to Windows >Preferences >Java >Installed JREs >Add >Standard VM. Extract it to somewhere on your hard drive, say, C:\dcevm. Download the pre-patched DCEVM for your platform.The quickest way is to get the pre-patched JRE here and just use it as your server runtime, no need to mess with your current JRE. Here is the catch: don't use the installation file from the official website to patch your JRE, it's obsolete and may not work with your version of Java. Needless to say, I was very excited and couldn't wait to share with my fellow developers here how I did it. After hours digging around and trying different ways of using the new VM, I managed to make it work without having to build my own installer. If all is fine, skip all the way to step 4 below. Update May 10 2014: Great news: there is a new DCEVM fork and the binary installers for JDK/JRE 1.7 are now available, thanks to Ivan Dubrov (more details in the comment section). IDE specific instructions can be found here: If all is well yo u can ignore the rest of this article, hurrahhh! The key is how to set it up, because unfortunately, the project website hasn't been updated and the binary setup hosted there doesn't work with JDK/JRE 1.7 (if it works for you anyhow or if you can build the binary yourself, congrats you can skip the steps 1-3 below). Check out if you h aven't, there you should find everything you need to get started. Update June 201 6: D CEVM seems to be going strong, the fork I mentioned before has been well maintained, J RE 1.8 support has been added and now there is even support for f ram ework configuration files hot-swapping, which effectively bring D CEVM closer than ever to JR e bel in terms of feature set. I haven't tried them all, but it looks like DCEVM is the most advanced one and yet requires minimal configurations. But if not, don't worry, there are free alternatives out there ( DCEVM, FakeReplace, Spring-loaded.). If you work for a company that buys you a commercial hot-swap solution, like JRebel, you're lucky because usually they work out of the box and offer more functionalities. All other changes (method signature, class members, etc) will require reloading the whole application. Only method body changes can be hot-replaced. This is because class hot-swapping in the JVM is severely limited. Other IDEs even require you to restart the server. With Tomcat and Eclipse for example, when you make just a small change in your Java class, it still takes at least a few seconds for the change to be reflected because the whole web app will need to be reloaded. PS - on a positive note, they don't cold call spam me anymore (even when I didn't have a license, it seemed they had stopped that sort of behavior).Those of you who work with web application development on a daily basis know very well that application reloading or server restarting is annoying. But when I find rebuilding and deploying to be more desirable than using JRebel sometimes (and I have a license), that can give you an idea of the headaches involved. I don't know of a good alternative, however. There's a VERY not zero cost to setting up JRebel and the last time I set it up I had crazy headaches getting some of the stuff to work properly. And for some customers I'm sure $500 is worth it (like if you have a simple Java application(s) that you are constantly editing).īut if you're like me and you work across a number of platforms and have a (probably too) complex project that you work on, it gets sketchy at that price. They do all this fuzzy math around "saving time", but honestly, if I had to tally all the JRebel bug time I've spent it would paint a different picture of the product. It's not rock solid enough to be worth that kind of money. Honestly, I too have grown annoyed at their prices.
