## org.apache.struts2.spring
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:
  org.apache.commons.jci.monitor.FilesystemAlterationListener, 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.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>
