Method Detail

getHostName

public static String getHostName(InetAddress address)

This method tries to determine the hostname of the given InetAddress without triggering a reverse DNS lookup. InetAddress.getHostName() triggers a reverse DNS lookup which can be very costly in cases where reverse DNS fails. Tries to parse a symbolic hostname from InetAddress.toString(), which is documented to return a String of the form "hostname / literal IP address" with 'hostname' blank if not already computed & stored in address.

If the hostname cannot be determined from InetAddress.toString(), the value of InetAddress.getHostAddress() is returned.

Parameters:

address - The InetAddress whose hostname has to be determined

Returns:

hostname, if it can be determined. host address, if not.

getDestinationEPR

public static org.apache.axis2.addressing.EndpointReference getDestinationEPR(org.apache.axis2.context.MessageContext msgContext)

Get the EPR for the message passed in

Parameters:

msgContext - the message context

Returns:

the destination EPR

removeUnwantedHeaders

public static void removeUnwantedHeaders(org.apache.axis2.context.MessageContext msgContext,
                                         TargetConfiguration targetConfiguration)

Remove unwanted headers from the http response of outgoing request. These are headers which should be dictated by the transport and not the user. We remove these as these may get copied from the request messages

Parameters:

msgContext - the Axis2 Message context from which these headers should be removed

targetConfiguration - configuration for the passThrough handler

determineHttpStatusCode

public static int determineHttpStatusCode(org.apache.axis2.context.MessageContext msgContext)

Determine the Http Status Code depending on the message type processed
(normal response versus fault response) as well as Axis2 message context properties set via Synapse configuration or MessageBuilders.

Parameters:

msgContext - the Axis2 message context

Returns:

the HTTP status code to set in the HTTP response object

getOMOutputFormat

public static org.apache.axiom.om.OMOutputFormat getOMOutputFormat(org.apache.axis2.context.MessageContext msgContext)

builderInvoked

                                               org.apache.http.nio.NHttpServerConnection conn,
                                               SourceConnections connections)

finishUsingTargetConnection

public static void finishUsingTargetConnection(org.apache.http.HttpResponse response,
                                               org.apache.http.nio.NHttpClientConnection conn,
                                               TargetConnections connections)
