Hi all,
I'm having big trouble while trying to acces to the parameters values.
I'm simply trying to retrieve a parameter value from my interceptor class.
The Action class that is intercepted implements the ParameterAware
interface and has getter and setter method
related to parameters attribute which is a Map.
Here is the sample code.
public String intercept(ActionInvocation invocation) throws Exception
{
ActionSupport action = (ActionSupport)
invocation.getAction();
Map session =
invocation.getInvocationContext().getSession();
Map parameters =
invocation.getInvocationContext().getParameters();
String loginAttempt =
(String)parameters.get(Constants.LOGIN_ATTEMPT_KEY);
return invocation.invoke ();
}
When the line in bold is reached, I' getting a ClassCastException.
Here is an extract of the stacktrace

Thank in advance.
