name.matthewgreet.strutscommons.interceptor.UnhandledExceptionWriterInterceptor
All Implemented Interfaces:
com.opensymphony.xwork2.interceptor.Interceptor, Serializable
public class UnhandledExceptionWriterInterceptor extends com.opensymphony.xwork2.interceptor.AbstractInterceptor
Detects an exception not handled by the form driven action, logs it, changes the result to 'input' or 'error' as needed and, if it implements ValidationAware, writes an action error for the user. Checked exceptions are regarded as an application rejection and use the 'input' result. Unchecked exceptions are regarded as system failures and use the 'error' result.
