In contrast to standard Java, where the HotSwap is limited to in-body code changes, the DCEVM + HotswapAgent allow following code changes: Server restart is not required for each code change. loading the code changes directly in the running server. HotSwap does exactly the same thing what JRebel does, i.e. HotSwap is free and open source alternative to JRebel. Problem with JRebel is, it is not free to use and pretty expensive.įree and open source alternative to JRebel is HotSwap. In simple words JRebel loads the code changes in the live running server, server restart is not required at all. JRebel helps developers to be more productive by viewing code changes in real time and maintaining state. JRebel fast tracks Java application development by skipping the time-consuming build and server restart steps in the development process. Many Hyrbis developers are aware of JRebel. Even if one-line code change is done, developer has to wait for around an hour to see the output of the changes. Subsequently, restarting the Hybris server to load the changes.īuilding Hybris project usually takes 20 minutes and restarting server on windows machine takes around 25 to 35 minutes.

In IDEA, I also enabled the jrebel remote mode and successfully built the connection. Then I deploy the JAR on remote server using java -agentpath:jrebel/lib/libjrebel64.so -Drebel.remoting_plugin=true -jar /build/libs/app.jar. I’ve checked that the JAR did have both rebel.xml and rebel-remote.xml. The rebel.xml file has the directory containing the. I’ve generated both rebel.xml and rebel-remote.xml files in IDEA.

However, after deploying the jar on remote server, the jrebel can’t update the application.įor the spring boot application, I used gradle to build a JAR file. Hello, I’m trying to enable jrebel for a spring boot application. The class itself will call the constructor again, but no change is seen from the rest api generated by swagger. I have to re-deploy the war every time if I want to see the change in swagger. Legacy methods will be if I make a change to the above class and do a recompile, no changes are reflected within swagger. Note that any references for the URI /api/v1 require authorization.
