Dependency checking

Resin restarts web-apps and virtual hosts when it detects a change in the <web-app> or <host>. The restart behavior is controlled by the <redeploy-mode> tag which defaults to "automatic".

Checked Resources

Resin checks the following resources to see if the web-app or host should be restarted:

• Any classes in WEB-INF/classes
• Any jars in WEB-INF/lib
• Any additional classes or jars specified in a <class-loader> tag
• Any WEB-INF/resin-web.xml
• Any WEB-INF/web.xml
• resin.conf
• Any other configuration file read by a <resin:import>
• A source .war file configured by <archive-path> or a <web-app-deploy> or <host-deploy>.
• Any file added in a <dependency> tag

<dependency-check-interval>

The <dependency-check-interval> directive configures how often Resin should check <web-app> or <host> dependencies for restarting. The restarting behavior is controlled by the <redeploy-mode> directive.

<dependency-check-interval> uses Period Configuration values.

During development, a <dependency-check-interval> of "2s" is appropriate. For deployment, a much large value like "1h" or "1d" is appropriate.
