We also renamed the tool once more to "JRebel" due to trademark issues. We also introduced an extension API that allowed to make use of JavaRebel features in third-party applications as well as build plugins for JavaRebel to support changes in framework configuration. EAR archives as per Java EE specification. In 2009 we released the version 2.0, which supported a layer of indirection on top of the ClassLoader API that allowed the users to edit classes and resources in their workspace instead of packaging them into. During 2007 we developed and released a prototype initially code-named "Badger" and for the public release renamed toġ Email: - see front matter © 2011 Elsevier B.V. Thus no new methods, fields or constructors are allowed.Īt the end of 2006 we came up with an idea for extending the Java virtual machine with a mechanism that would allow to change the class bytecode beyond the limits of the HotSwap protocol. Unfortunately only a very restricted set of changes is allowed namely HotSwap allows changes to the method bodies, but does not allow changing the class signature or inheritance hierarchy. This allows to update the application classes without redeploying it. Every time developers want to make changes to the running application they need to deploy it, which can take from a few seconds in the best case to several minutes in the worst.Īn alternative way to update an application is using the HotSwap protocol, available from the Java EE debugger. This step is necessary after the application has been compiled and packaged into an archive as per Java EE specification. Java EE development day-to-day activities involves deploying the application to the Java EE server. Keywords: bytecode, JRebel, ClassLoader, API, retroactive In this live demo we will show how it can be used in real-life projects to cut development time by 8 to 18 per cent. It uses bytecode manipulation extensively, both for the just-in-time class translator and numerous integrations with the Java SE and EE APIs. It extends the Java Virtual Machine with a mechanism that allows seamless class reloading. JRebel started as an academical project that became a successful commercial product used by thousands of developers worldwide. of Computer Science University of Tartu Tartu, Estonia ![]() ELSEVIER Electronic Notes in Theoretical Computer Science 264 (4) (2011) 51-57ĭept.
