Fluent Configuration

The FluentConfigurator uses a the Fluent Interface style as described by Martin Fowler.

To wire up the configuration programmatically rather than having to use dwr.xml, you'll need to:

  • Create a concrete implementation of org.directwebremoting.fluent.FluentConfigurator which implements the configure() method.
  • Add an init param 'customConfigurator' to the DWR servlet in web.xml to point at your new class.

The implementation of configure() will look something like this:

public void configure() {
   withConverterType("dog", "com.yourcompany.beans.Dog");
   withCreatorType("ejb", "com.yourcompany.dwr.creator.EJBCreator");
   withCreator("new", "ApartmentDAO")
       .addParam("scope", "session")
       .addParam("class", "com.yourcompany.dao.ApartmentDAO")
       .exclude("saveApartment")
       .withAuth("method", "role");
   withCreator("struts", "DogDAO")
       .addParam("clas", "com.yourcompany.dao.DogDAO")
       .include("getDog")
       .include("getColor");
   withConverter("dog", "*.Dog")
       .addParam("name", "value");
   withSignature()
       .addLine("import java.util.List;")
       .addLine("import com.example.Check;")
       .addLine("Check.setLotteryResults(List nos);");
}
