How to change Wicket to deployment mode

 
By default, Wicket is running in development mode. In this post we will see how to change that to Deployment mode ( commonly called as production mode ).
 
There is two method to change wicket to run in deployment (production) mode :
 

1. web.xml

 
The first st way is add a ‘€œconfiguration’€ context-param in web.xml.
 
File : web.xml
 

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app ... >

  ...

  <filter>
    <filter-name>wicket.app</filter-name>
    <filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
    <init-param>
      <param-name>applicationClassName</param-name>
      <param-value>org.starobjects.wicket.viewer.app.WicketObjectsApplication</param-value>
    </init-param>
    <init-param>
      <param-name>configuration</param-name>
      <param-value>deployment</param-value>
    </init-param>
  </filter>

</web-app>

 
The system property is checked first, allowing you to add a web.xml param for deployment, and a command-line override when you want to run in development mode during development.
 

2. Wicket getConfigurationType()

 
The 2nd way is override the Wicket application getConfigurationType() method.
 
File : Wicket Application class
 

import org.apache.wicket.Application;
import org.apache.wicket.protocol.http.WebApplication;
 
public class WicketApplication extends WebApplication
{
	@Override
	public String getConfigurationType()
        {
 
		return Application.DEPLOYMENT;
	}
}

 

 

How do I know in what mode (DEVELOPMENT/DEPLOYMENT) my application runs?

 
As of Wicket 1.3.0, you can call Application.getConfigurationType(). Prior to that, there is no flag telling you in which mode you are. If you want a flag subclass Application.configure() store the “configurationType” parameter in a variable.
 

if (DEVELOPMENT.equalsIgnoreCase(configurationType))
{
    log.info("You are in DEVELOPMENT mode");
    getResourceSettings().setResourcePollFrequency(Duration.ONE_SECOND);
    getDebugSettings().setComponentUseCheck(true);
    getDebugSettings().setSerializeSessionAttributes(true);
    getMarkupSettings().setStripWicketTags(false);
    getExceptionSettings().setUnexpectedExceptionDisplay(
                    UnexpectedExceptionDisplay.SHOW_EXCEPTION_PAGE);
    getAjaxSettings().setAjaxDebugModeEnabled(true);
}
else if (DEPLOYMENT.equalsIgnoreCase(configurationType))
{
    getResourceSettings().setResourcePollFrequency(null);
    getDebugSettings().setComponentUseCheck(false);
    getDebugSettings().setSerializeSessionAttributes(false);
    getMarkupSettings().setStripWicketTags(true);
    getExceptionSettings().setUnexpectedExceptionDisplay(
                    UnexpectedExceptionDisplay.SHOW_INTERNAL_ERROR_PAGE);
    getAjaxSettings().setAjaxDebugModeEnabled(false);
}
