One good news is the guy behind the project now works for Oracle and he made an enhancement proposal for it to be integrated into the JVM. I can't imagine developing my Java application without it. It would be nice to have the ability to hot-swap framework configuration files as well, like with JRebel, but it's still fine otherwise, at least for me, because I find myself changing configuration files much less often than modifying view files and Java classes.ĭCEVM is definitely my hotswaping tool of choice now.

With DCEVM you just patch your JRE once (the one on development environment of course), then you never worry about it again. It doesn't require any plug-in to be installed into your IDE, it doesn't produce any configuration files to be complained by your source version control like JRebel does with every Java projects. Thing I like the most about DCEVM is transparency. Make some changes to your Java class, hit refresh on your browser to see the change reflected immediately. 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. Those of you who work with web application development on a daily basis know very well that application reloading or server restarting is annoying.
