Most often, the Action Mappings will be automatically reloaded if the WAR is redeployed. If not, there are two things you can try: Setting the reload property to true and destroying the configuration.
Setting Reload to True
struts.properties
### Configuration reloading ### This will cause the configuration to reload struts.xml when it is changed struts.configuration.xml.reload=true
Reloading the Configuration
Create a utility Action that calls reload.
MyUtilityAction.java
// ...
String execute() {
Dispatcher.getIntance().getConfigurationManager().reload();
return SUCCESS;
}
Invoking reload will force Struts to reload the configuration.
