hotdeploy

We are wondering how to setup GlassFish 3.1.2 real hot deployment, that is not just the usual setting How can I hot deploy using the glassfish adapter in Eclipse but how to make it possible that the Eclipse GlassFish plugin will silently push changed XHTML, CSS, etc. files to the server as you save the file in Eclipse. How is it officially setup? Again, I tested this several times now, hot-deploying just-changed XHTML(/JSF), CSS files on save just doesn't work. When setting to Never publish automatically nothing happens when saving a JSF file. When setting to Automatically publish when

Recently, I was reading book about Erlang which has hot deployment feature. The deployment can be done without bringing the system down. All the existing requests will be handled by old version of code and all the new request after deployment will be served by the new code. In these case, both the versions of code available in runtime for sometime till all the old requests are served. Is there any approach in Java where we can keep 2 versions of jar files? Is there any app/web servers support this? There are many ways to achieve hot deployment in the Java world, so you'll probably need to be a

I'm looking for a simple to use system in Java which creates a REST service for me. So I found dropwizard but as far as I can use google it turns out it lacks hot deployment although jetty is able to do so. When using the maven-shade-plugin it takes at least 10 seconds to build the thing. Also my IDE reports that it cannot use compile on save feature (aka hot deployment) when the shade-plugin is involved. Can I use hotdeployment somehow? Or what can I use instead? Update : If nothing will fix this I'll probably use a combination of jersey&guice etc which is explained in this post You don't

I'm curious does anyone know the details on how frameworks like Grails or Play detect changes in the code and automatically trigger a recompilation without rebooting the app server? Is there something specific to Groovy's compiler or its dynamic nature that allows this to easily happen? For background, I have a custom code generation stage during my build process that I would love to be able to have similar edit-and-refresh capabilities. Thanks in advance for any pointers, even if I have to sift through code to get the larger picture. Edit: I should clarify that I'm not looking to build a

I am having trouble Hot Deploying a Spring-MVC 4.0 (not SpringBoot) Web Application. I am trying to go xml-less and just use JavaConfig. OutOfMemoryErrors result when I remove web.xml , or when I deploy an empty web.xml with nothing but an empty element . This does not happen every time the app is hot-deployed, and after a successful hot-deployment, the app does work correctly, but after three or four hot-deployments with this configuration the following error occurs: Jul 03, 2015 10:49:43 AM org.springframework.web.context.ContextLoader initWebApplicationContext SEVERE: Context initialization
