Method Details

isUnwrapServletException

public boolean isUnwrapServletException()

Returns:

True if ServletException is unwrapped for RequestDispatcher.ERROR_EXCEPTION

setUnwrapServletException

public void setUnwrapServletException(boolean unwrapServletException)

Parameters:

unwrapServletException - True if ServletException should be unwrapped for RequestDispatcher.ERROR_EXCEPTION

getErrorPage

public String getErrorPage(javax.servlet.http.HttpServletRequest request)

Specified by:

getErrorPage in interface ErrorHandler.ErrorPageMapper

getErrorPages

public Map<String,String> getErrorPages()

setErrorPages

public void setErrorPages(Map<String,String> errorPages)

Parameters:

errorPages - a map of Exception class names or error codes as a string to URI string

addErrorPage

public void addErrorPage(Class<? extends Throwable> exception,
 String uri)

Adds ErrorPage mapping for an exception class. This method is called as a result of an exception-type element in a web.xml file or may be called directly

Parameters:

exception - The exception

uri - The URI of the error page.

addErrorPage

public void addErrorPage(String exceptionClassName,
 String uri)

Adds ErrorPage mapping for an exception class. This method is called as a result of an exception-type element in a web.xml file or may be called directly

Parameters:

exceptionClassName - The exception

uri - The URI of the error page.

addErrorPage

public void addErrorPage(int code,
 String uri)

Adds ErrorPage mapping for a status code. This method is called as a result of an error-code element in a web.xml file or may be called directly.

Parameters:

code - The HTTP status code to match

uri - The URI of the error page.

addErrorPage

public void addErrorPage(int from,
 int to,
 String uri)

Adds ErrorPage mapping for a status code range. This method is not available from web.xml and must be called directly.

Parameters:

from - The lowest matching status code

to - The highest matching status code

uri - The URI of the error page.

doStart

protected void doStart()
                throws Exception

Description copied from class: ContainerLifeCycle

Starts the managed lifecycle beans in the order they were added.
