Eclipse Tomcat does not update

I am developing an application with SpringMVC and Tomcat using Eclipse. The problem is that the server is not updating the changes I am making.

One example:

@RequestMapping(value = "test", method = RequestMethod.GET) public ModelAndView test(){ ModelAndView mv = new ModelAndView("test"); System.out.println("test"); return mv; }

Each time I click on the display URL, Eclipse prints a test in my console. If I comment on println , I get the same result.

Attempts to fix the problem:

  • clear Tomcat directory
  • restart the server
  • close eclipse
  • add / remove a project on the Server tab
  • remove the jsp that uses the method
  • various browsers

All without effect. It just looks like Tomcat is not updating any changes made to the code.

To make an Eclipse Tomcat update automatic or hot, you need to make certain changes to the server configuration:

Following are the steps:

  • Double-click on Tomcat Server , see the "publishing" tab in the "Overview" view, make sure that "Automatically publish when resources change" . This should be the default option to support "hot deploy" resources, for example: JSP, XML, and property files.

  • On the Tomcat Plugin page, click on the "Modules" view, select Module, and click Modify and make sure "Auto Reload" strong> "Disabled" . Enabled by default.

  • Run the project in DEBUG mode. Hot Deploy is only supported in DEBUG mode.

Two more things to check:

  • deployment directory : in the tomcat server user interface and in accordance with the “deployment path” configuration, make sure that the output directory has read / write access (you can also delete it and try to publish again: check the expected output resources / classes).
  • deployment layout : in the project properties menu; in the Install Installation section, make sure that you publish all the resources you need. For example, in my case, I load / generate some elements from the phases of the user maven plugin, and these resources are not published by default. I needed to add some target subdirectories here ...
