It does not create any new class loaders, instead, it extends the existing ones with the ability to manage reloaded classes. This is how JRebel works: How does JRebel work? JRebel integrates with the JVM and application servers mainly on the class loader level. add/delete method) hot deploy for EJB 3.0 components. Why are you seemingly trying to reinvent the wheel? Is there some advantage(s) to your design/solution over JRebel? Will yours incrementally hot deploy changes to EJB 3.x components? JRebel is claiming interface change (e.g. I'm also wondering how it will behave with EJB 3.1 and optional local interfaces. JBoss 6.0.0.M1, JRebel 3.0-M2-SNAPSHOT, JSF 2.0 (Mojarra), Weld 1.0.x, EJB 3.0.ĭo the EJB JARs ship with JBoss 6? The server/default/lib is empty in AS 6, it's not empty in AS 4.2 (and some EJB JARs are located in there).Īnyways, bottom line: is it possible to hot deploy EJBs in a JSF2/Weld app in JBoss 6 now?ītw, I'm not too happy about not being able to hot deploy bijection and or But this is a very good first step (assuming I'm making some config mistakes!) towards EJB higher-level dev productivity.
The method invocation on the Seam component fails because the method is not found.Īnyways, I'm wondering if I would be able to use the following combination of technologies: So I have been testing with out existing Seam 2.1.1.GA app at work with this new version of JRebel and so far have not been able to hot deploy a local interface method addition and corresponding class impl method addition.
Jrebel core functionality (reloading classes) should work nicely but functionality that requires integration with the specific container/framework (such as adding a new field) may be missing and that's where we would need user feedback to know what features users really miss. About using jrebel with seam/ejb/jsf/weld we don't have any special instructions. EJB 3.1 is not supported by any of the released jboss versions so we just have to wait while the jboss guys implement it and see if we need to do any special integration. We would be interested to know how well it works on a real project and what more we could do to make jrebel work better with seam. You can donwload the nightly build from also add -Drebel.jboss_plugin=true -Drebel.allow_bytecode_proxy=true to jvm arguments. Here is the email thread: We have implemented adding new methods to ejb interfaces on jboss in nightly builds. Is there a conflict between jrebel and debug mode?

#JREBEL ZEROTURNAROUND UPDATE#
When I update the class, jrebel throws the following log exception. I started the project with jrebel's debug mode.
