author: Various -

Constructor:

Constructor:
public ServletException() { super(); } Constructs a new servlet exception.
public ServletException(String message) { super(message); } Constructs a new servlet exception with the specified message. The message can be written to the server log and/or displayed for the user. Parameters: `message` - a `String` specifying the text of the exception message
public ServletException(Throwable rootCause) { super(rootCause); this.rootCause = rootCause; } Constructs a new servlet exception when the servlet 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 `ServletException`, this method can be overridden to create an exception message designed for a specific locale. Parameters: `rootCause` - the `Throwable` exception that interfered with the servlet's normal operation, making the servlet exception necessary
public ServletException(String message, Throwable rootCause) { super(message, rootCause); this.rootCause = rootCause; } Constructs a new servlet exception when the servlet needs to throw an exception and include a message about the "root cause" exception that interfered with its normal operation, including a description message. Parameters: `message` - a `String` containing the text of the exception message `rootCause` - the `Throwable` exception that interfered with the servlet's normal operation, making this servlet exception necessary

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

Parameters:

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