Description

Hi Wicketers!

I found in guide in A.1. Switching Wicket to DEPLOYMENT mode section:

The last option is to set it in your Java code (e.g. in the init-method of your WebApplication):
setConfigurationType(RuntimeConfigurationType.DEPLOYMENT);

however setting up this type in init() method of WicketApplication class throws an exception:

SEVERE [RMI TCP Connection(2)-127.0.0.1] org.apache.catalina.core.StandardContext.filterStart Exception starting filter [WicketFilter] javax.servlet.ServletException: java.lang.IllegalStateException: Configuration type is write-once. You can not change it. Current value='DEPLOYMENT'

In my opinion guide lines in this section should be changed to (e.g.):

The last option is to override getConfigurationType() method in your class that extends WebApplication):

public class WicketApplication extends WebApplication
{
    @Override
    public void init()
    {
        super.init();
        // add your configuration here
    }

    @Override
    public RuntimeConfigurationType getConfigurationType()
    {
        return RuntimeConfigurationType.DEPLOYMENT;
    }
}
