hotswap

问题 The java hotswap feature save a lot of time for me. However, it has many limitations (like schema change is not supported). Any idea if the limitation is going to be addressed any sooner? According to this forum entry, it seems to be ignored. I know that products like JRebel helps. But does anyone know about any open source tools for this? 回答1: You can check out Dynamic Code Evolution VM (also at http://java.net/projects/dcevm) 回答2: JavaRebel is a good tool, but it need you purchase. I'd like

问题 When editing Java code in Eclipse I can modify the code while it's running in various ways and have those changes take effect without restarting my program. What is the technology underlying this feature? Is it part of Eclipse, or is it something I can do with the command line tools and the tools that come with the JDK? 回答1: Its part of the JVM and its called HotSwap. http://download.oracle.com/javase/1.4.2/docs/guide/jpda/enhancements.html 回答2: This feature is usually called "hot code

问题 After loading a DLL library using LoadLibrary("file.dll") visual studio also opens and locks file.pdb . The problem is - the file.pdb is kept locked even after calling FreeLibrary(...) . It is necessary to recompile file.dll and reload it once again ( externally, outside of MSVS , using CL.exe ), but the compilation fails because file.pdb is still locked. How to make Visual Studio 2015 release the file lock? 回答1: Coincidentally I've stumbled upon a solution to this: Go to Tools -> Options

问题 1) Is there any special setting/configuration required to enable hot swap debugging on Android? Example case: Add breakpoint just after entering activity's onCreate method. Add new line on the fly after the breakpoint (dummy "if (1==1) return;" code) Step to next instruction --> Problem: my debugger doesn't break at this line, instead skipping to the next leading me to believe the new line was not hot swapped into the VM. 2) Does only the emulator support hot swap? Are there any handsets

问题 I have two jar files. One.jar contains main method to start the process and other two.jar contains just class files. In One.jar I have referenced two.jar in its manifest classpath. One.jar contains mechanism to dynamically load the classes using Class.forName() I want to deploy the One.jar only once for lifetime. Will not be making any changes to it. Changes will be happening only in two.jar I want to hot swap the two.jar with updated two.jar. I have seen other posts about hot swapping too

问题 First of all, I would like to say that there is plenty of pages on StackOverflow and I tried all I found related, but I am doing something wrong. I have IntelliJ server set up to: server Tomcat 8 JDK 8u65 Maven IntelliJ 14 In Run/Debug configuration I have set VM Options: On Update action: Update resources On frame deactivation: Update classes and resources Before launch: Build xxx.war exploded Deployment tab set to deploy xxx.war exploded If I change the body of any class (e.g.returned value

问题 The deployment we follow is that we use runAssembler.bat to build an ear file and deploy it in a app server. We are using weblogic and jboss for testing purposes of the modules we built. However for every small change, we need to run runAssembler and build a new ear and deploy it in app server and restart the server. I would like to find out if anyone figured out a way to do Hotswapping of class files which are generated by the code we write in ATG environment in either weblogic or jboss. 回答1

问题 Usually i start tomcat using mvnDebug tomcat:run . After Code-change i need to use mvn tomcat:redeploy . This is sub-optimal because i often only change content of existing method-bodys. Can I HotSwap the method's body into the runtime, and hot-redeploy as a fallback? I have unfortunatally nothing found like a maven-hotswap-plugin . faces-config.xml ... <application> <view-handler>com.sun.facelets.FaceletViewHandler</view-handler> <locale-config> <default-locale>de_DE</default-locale> <

问题 I've got the following embedded Jetty setup: ServletContextHandler topHandler = new ServletContextHandler(server, contextPath); // Set path of static resources topHandler.setBaseResource(...); // Bind dynamic content to /api RootResource rootResource = new RootResource(); FilterHolder restApiHandler = new FilterHolder(rootResource); for (Entry<String, String> parameter : initParams.entrySet()) restApiHandler.setInitParameter(parameter.getKey(), parameter.getValue()); topHandler.addFilter
