All Implemented Interfaces:

Serializable

public class ParameterAbsentException

extends Exception

Signals that a parameter (such as an HTTP environmental variable) was not present.

This method can be used to assign a default value in the case of an absent parameter, for example, with:

 try {
     newState = request.getStringParameter(StatefulServlet.STATE_PNAME);
 } catch(ParameterAbsentException paE) {
     newState = StatefulServlet.STATE_DFLT;
 }
