@Deprecated(since="2021-05-27")
public class ErrorHandler
extends AbstractHandler

Deprecated.

The Eclipse Jetty and Apache Felix Http Jetty packages are no longer supported.

Handler for Error pages An ErrorHandler is registered with ContextHandler.setErrorHandler(ErrorHandler) or Server.setErrorHandler(ErrorHandler). It is called by the HttpResponse.sendError method to write an error page via handle(String, Request, HttpServletRequest, HttpServletResponse) or via badMessageError(int, String, HttpFields) for bad requests for which a dispatch cannot be done.

handle

public void handle(String target,
 Request baseRequest,
 HttpServletRequest request,
 HttpServletResponse response)
            throws IOException,
ServletException

Deprecated.

Description copied from interface: Handler

Handle a request.

Specified by:

handle in interface Handler

Specified by:

handle in class AbstractHandler

Parameters:

target - The target of the request - either a URI or a name.

baseRequest - The original unwrapped request object.

request - The request either as the Request object or a wrapper of that request. The HttpConnection.getCurrentConnection().getHttpChannel().getRequest() method can be used access the Request object if required.

response - The response as the Response object or a wrapper of that request. The HttpConnection.getCurrentConnection().getHttpChannel().getResponse() method can be used access the Response object if required.

Throws:

IOException - if unable to handle the request or response processing

ServletException - if unable to handle the request or response due to underlying servlet issue

doError

public void doError(String target,
 Request baseRequest,
 HttpServletRequest request,
 HttpServletResponse response)
             throws IOException

Deprecated.

Throws:

IOException

badMessageError

public ByteBuffer badMessageError(int status,
 String reason,
 HttpFields fields)

Deprecated.

Bad Message Error body

Generate an error response body to be sent for a bad message. In this case there is something wrong with the request, so either a request cannot be built, or it is not safe to build a request. This method allows for a simple error page body to be returned and some response headers to be set.

Parameters:

status - The error code that will be sent

reason - The reason for the error code (may be null)

fields - The header fields that will be sent with the response.

Returns:

The content as a ByteBuffer, or null for no body.

getCacheControl

public String getCacheControl()

Deprecated.

Get the cacheControl.

Returns:

the cacheControl header to set on error responses.

setCacheControl

public void setCacheControl(String cacheControl)

Deprecated.

Set the cacheControl.

Parameters:

cacheControl - the cacheControl header to set on error responses.

isShowServlet

public boolean isShowServlet()

Deprecated.

Returns:

True if the error page will show the Servlet that generated the error

setShowServlet

public void setShowServlet(boolean showServlet)

Deprecated.

Parameters:

showServlet - True if the error page will show the Servlet that generated the error

isShowStacks

public boolean isShowStacks()

Deprecated.

Returns:

True if stack traces are shown in the error pages

setShowStacks

public void setShowStacks(boolean showStacks)

Deprecated.

Parameters:

showStacks - True if stack traces are shown in the error pages

setShowMessageInTitle

public void setShowMessageInTitle(boolean showMessageInTitle)

Deprecated.

Parameters:

showMessageInTitle - if true, the error message appears in page title

getShowMessageInTitle

public boolean getShowMessageInTitle()

Deprecated.

getErrorHandler

public static ErrorHandler getErrorHandler(Server server,
 ContextHandler context)

Deprecated.
