JBoss EAP 7 file watch service does not detect changes in subdirectories of exploded deployment on Windows

Solution Unverified - Updated

Environment

  • Red Hat JBoss Enterprise Application Server (EAP)
    • 7.0
    • 7.1
    • 7.2
  • Microsoft Windows

Issue

  • Changes in subfolder of exploded deployment are not detected by file watch service in JBoss EAP 7 on Windows
  • JSP hot reloading does not work in subdirectories of an exploded deployment in JBoss EAP 7 running on Windows

Resolution

This is a bug which has been fixed in EAP 7.2.3 or later:

If you require JSP hot reloading until the above JIRA is fixed, a workaround is enabling development mode. Set development="true" attribute on <jsp-config>:

<servlet-container name="default">
    <jsp-config development="true" modification-test-interval="15"/>
    <websockets/>
</servlet-container>

You can also tune the modification-test-interval attribute, which is 4 (seconds) by default, to change the minimum amount of time between two tests for updates. However, note that the development mode triggers a recompilation of the JSP files after the time specified to the modification-test-interval parameter (= the recompilation happens on the request regardless of having the JSP change).
