问题 I have been developing custom plugin for HotSwapAgent, but encountered weird issue with classloader missing plugin class. This is the exception thrown by ####<Feb 9, 2015 12:45:54 AM PST> <Notice> <Stdout> <testbox.mycompany> <AdminServer> <Thread-87> <<WLS Kernel>> <> <> <1423471554463> <BEA-000000> <HOTSWAP AGENT: 0:45:54.463 ERROR (org.hotswap.agent.config.PluginRegistry) - Error in plugin initial processing for plugin package 'mycompany.infrastructure.hotswap.agent' java.lang

问题 What is JVM Hot Swapping? Many definitions say that this feature allows code to updated on the fly during de-bugging. And a few restrictions such as hot swapping is limited to updating method bodies only, and trying to add methods and fields to classes would not succeed. Can anyone explain this with code. 回答1: All it means is that you can make certain changes to your code while in the middle of a debugging session, and have those changes take effect immediately, without having to restart the

问题 I have a question about hot swap agent. I configured it with java 8 and tomcat 8.0.26 64 bit. When I start server under Eclipse I got some errors: Caused by: compile error: cannot find constructor org.apache.catalina.webresources.FileResource(org.apache.catalina.webresources.StandardRoot,java.lang.String,java.io.File,boolean) and Caused by: org.hotswap.agent.javassist.NotFoundException: getResource(..) is not found in org.apache.catalina.loader.WebappClassLoader I put more detailed stack

问题 I usually start the AS in debug mode so that I can use hot swap. But how can I get that if whenever I change a configuration or java file Netbeans sends it to Glassfish and automatically redeploys my application? Some details: 1 - Maven war application. 2 - Compile on Save: for both application and test execution. 3 - Java Debugger: Apply code changes after save. 回答1: To use the hot-swap capabilities of JPDA in a NetBeans/GlassFish environment, you need to turn off the 'Deploy on save'

问题 Any idea if there is a way to make the following code to work class Test(object): def __init__(self, var): self.var = var def changeme(self): self = Test(3) t = Test(1) assert t.var == 1 t.changeme() assert t.var == 3 is something like the following safe to use for more complex objects (like django models, to hot swap the db entry the instance is referring to) class Test(object): def __init__(self, var): self.var = var def changeme(self): new_instance = Test(3) self.__dict__ = new_instance._

问题 Assume we have a trivial Java program that consists of just one class: public class HelloWorld { private static void replacable(int i) { System.out.println("Today is a nice day with a number " + i); } public static void main(String[] args) throws Exception { for(int i = 0; i < 100000; ++i) { replacable(i); Thread.sleep(500); } } After it's compiled and run, output will be this: Today is a nice day with a number 0 Today is a nice day with a number 1 Today is a nice day with a number 2 Today is

问题 I tried all tips and tricks that I found here and in docs, but still no luck. I have Spring webapp with Thymeleaf. Resources and templates are not reloaded when I call update in IDEA (it says nothing to reload). I can then press ctrl+f5 in a browser like crazy, changes are just not there. Everything is configured in one Java class like this: @EnableWebMvc public class MvcConfig extends WebMvcConfigurerAdapter implements ApplicationContextAware { My folder structure now looks like this, but I
