sometimes we might need to work directly with “raw” web entities such as user session, web request, query parameters, and so on. For example this is necessary if we want to store an arbitrary parameter in object we must use the getMetaData(MetaDataKey key) method. In the following example we set a java.sql.Connection object in the application’s metadata so it can be used by any page of the application: page. 10.1. PageParameters A common practice in web development is to pass data to a page using query string parameters (like ?paramName1=paramValu1¶mName2=paramValue2…). Wicket offers a more flexible
