## Class ClassReloadingXMLWebApplicationContext

- java.lang.Object
- - org.springframework.core.io.DefaultResourceLoader
  - - org.springframework.context.support.AbstractApplicationContext
    - - org.springframework.context.support.AbstractRefreshableApplicationContext
      - - org.springframework.context.support.AbstractRefreshableConfigApplicationContext
        - - org.springframework.web.context.support.AbstractRefreshableWebApplicationContext
          - - org.springframework.web.context.support.XmlWebApplicationContext
            - - org.apache.struts2.spring.ClassReloadingXMLWebApplicationContext

- All Implemented Interfaces:
    Closeable, AutoCloseable, org.apache.commons.jci.monitor.FilesystemAlterationListener, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanFactory, org.springframework.beans.factory.BeanNameAware, org.springframework.beans.factory.DisposableBean, org.springframework.beans.factory.HierarchicalBeanFactory, org.springframework.beans.factory.InitializingBean, org.springframework.beans.factory.ListableBeanFactory, org.springframework.context.ApplicationContext, org.springframework.context.ApplicationEventPublisher, org.springframework.context.ConfigurableApplicationContext, org.springframework.context.Lifecycle, org.springframework.context.MessageSource, org.springframework.core.env.EnvironmentCapable, org.springframework.core.io.ResourceLoader, org.springframework.core.io.support.ResourcePatternResolver, org.springframework.ui.context.ThemeSource, org.springframework.web.context.ConfigurableWebApplicationContext, org.springframework.web.context.WebApplicationContext

      public class ClassReloadingXMLWebApplicationContext
      extends org.springframework.web.context.support.XmlWebApplicationContext
      implements org.apache.commons.jci.monitor.FilesystemAlterationListener

  This class can be used instead of XmlWebApplicationContext, and it will watch jar files and directories for changes and reload then changed classes.

  To use this class:

  - Set "struts.devMode" to "true"
  - Set "struts.class.reloading.watchList" to a comma separated list of directories, or jar files (absolute paths)
  - Add this to web.xml:

          <context-param>
               <param-name>contextClass</param-name>
               <param-value>org.apache.struts2.spring.ClassReloadingXMLWebApplicationContext</param-value>
           </context-param>

  - Add Apache Commons JCI FAM to the classpath. If you are using maven, add this to pom.xml:

          <dependency>
               <groupId>org.apache.commons</groupId>
               <artifactId>commons-jci-fam</artifactId>
               <version>1.0</version>
               <optional>true</optional>
          </dependency>
