Examples of org.apache.tapestry.ApplicationRuntimeException

org.apache.tapestry.ApplicationRuntimeException
General wrapper for any exception (normal or runtime) that may occur during runtime processing for the application. This exception is used when the intent is to communicate a low-level failure to the user or developer; it is not expected to be caught. The {@link #getCause() rootCause}property is a nested exception (Tapestry supported this concept long before the JDK did). @author Howard Lewis Ship @version $Id: ApplicationRuntimeException.java 243791 2004-02-19 17:38:13Z hlship $
