Method Detail

convertCarbonMsgToAxis2MsgCtx

public static org.apache.axis2.context.MessageContext convertCarbonMsgToAxis2MsgCtx(org.wso2.transport.http.netty.message.HttpCarbonMessage incomingCarbonMsg,
                                                                                    SourceConfiguration sourceConfiguration)

Create an Axis2 message context for the given HttpCarbonMessage. The carbon message may be in the process of being streamed.

Parameters:

incomingCarbonMsg - the http carbon message to be used to create the corresponding Axis2 message context

sourceConfiguration - source configuration

Returns:

the Axis2 message context created

getHostName

public static java.lang.String getHostName(java.net.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:

hostsname, if it can be determined. hostaddress, if not.

isHttpCarbonMessagePresent

public static boolean isHttpCarbonMessagePresent(org.apache.axis2.context.MessageContext msgContext)

Check if the HTTP_CARBON_MESSAGE is present in the message context.

Parameters:

msgContext - axis2 message context

Returns:

true if HTTP_CARBON_MESSAGE is present in the message context, false otherwise

shouldInvokeFormatterToWriteBody

public static boolean shouldInvokeFormatterToWriteBody(org.apache.axis2.context.MessageContext msgContext)

Checks if the request/response body should be written using the appropriate message formatter.

Parameters:

msgContext - axis2 message context

Returns:

true if the request was initiated from a non-http client or if the message has been built. Otherwise, return false if this is pass-through.

isMultipartContent

public static boolean isMultipartContent(java.lang.String contentType)

Check whether the content type is multipart or not.

Parameters:

contentType - value of the content type

Returns:

true for multipart content types

getRestUrlPostfix

public static java.lang.String getRestUrlPostfix(java.lang.String uri,
                                                 java.lang.String servicePath)

Generate the REST_URL_POSTFIX from the request URI.

Parameters:

uri - the Request URI as a string

servicePath - service path

Returns:

REST_URL_POSTFIX as a string

isRESTSupportedMediaType

public static boolean isRESTSupportedMediaType(java.lang.String contentType)

Checks if the HTTP request is REST based on the given Content-Type header.

Parameters:

contentType - Content-Type header

Returns:

whether the HTTP request is REST or not

populateSOAPVersion

public static int populateSOAPVersion(org.apache.axis2.context.MessageContext msgContext,
                                      java.lang.String contentType)

Populates the SOAP version based on the given Content-Type.

Parameters:

msgContext - axis2 message context

contentType - Content type of the request.

Returns:

0 if the content type is null. return 2 if the content type is application/soap+xml. Otherwise 1

isRESTRequest

public static boolean isRESTRequest(org.apache.axis2.context.MessageContext msgContext,
                                    java.lang.String contentType,
                                    int soapVersion,
                                    java.lang.String soapActionHeader)

Checks if the request should be considered as REST.

Parameters:

msgContext - axis2 message context

contentType - content-type of the request

soapVersion - SOAP version

soapActionHeader - SOAPAction header

Returns:

whether the request should be considered as REST

getDestinationEPR

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