Constructs a new JSP Tag exception when the JSP Tag needs to throw an exception and include a message about the "root cause" exception that interfered with its normal operation. The exception's message is based on the localized message of the underlying exception.

This method calls the getLocalizedMessage method on the Throwable exception to get a localized exception message. When subclassing JspTagException, this method can be overridden to create an exception message designed for a specific locale.

Parameters:

rootCause - the Throwable exception that interfered with the JSP Tag's normal operation, making the JSP Tag exception necessary

Since:

JSP 2.0
