There are four supplied methods in the Wicket framework for changing your configuration from development to deployment and vice-versa. The two possible values for this configuration parameter is “development” or “deployment”.

Method one, context-param in web.xml:

1
2
3
4
    <context-param>
        <param-name>configuration</param-name>
        <param-value>development</param-value>
    </context-param>

An init-param in the WicketFilter in your web.xml:

1
2
3
4
5
6
7
8
    <filter>
        <filter-name>wicketFilter</filter-name>
        <filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
        <init-param>
            <param-name>configuration</param-name>
            <param-value>development</param-value>
        </init-param>
        ...

A command-line parameter wicket.configuration:

1
    java ... -Dwicket.configuration=development

Overriding Application.getConfigurationType() in your Application class:

1
2
3
4
    @Override
    public String getConfigurationType() {
        return Application.DEVELOPMENT;
    }

In our environments, to reduce headache, we have the configuration in web.xml point to “deployment”, and in our Jetty Start class, we pass the command-line parameter locally to make it run in “development” mode.
