The servicemix-http components supports the XBean-based deployment. Since the servicemix-http component can be configured in both the consumer and provider roles, we have two sets of configuration parameters for the component. Let us look into the main configuration parameters:

servicemix-http as consumer: A sample servicemix-http consumer component configuration is shown as follows:

Sample Code

<http:endpoint
endpoint="HelloWebService" soap="true" role="consumer"
service="test:MyConsumerService" wsdlresource="http://localhost:8080/AxisEndToEnd/
services/HelloWebService?WSDL" defaultmep="http://www.w3.org/" target="_blank" rel="nofollow"
2004/08/wsdl/in-out" locationuri="http://localhost:8081/services/
HelloWebService"
targetservice="test:IHelloWebService"></http:endpoint>

The following table gives the explanation for the main configuration parameters:

Attribute Name	Type	Description	Mandatory or Not
service	QName	Service name of the proxy endpoint	Mandatory
endpoint	String	Endpoint name of the proxy endpoint	Mandatory
interfaceName	QName	Interface name of the proxy endpoint	Not Mandatory
targetService	QName	Service name of the target endpoint	Not Mandatory. Default is the value of the service attribute
targetEndpoint	String	Endpoint name of the target endpoint	Not Mandatory. Default is the value of the endpoint attribute
role	String	Whether a consumer or a provider	Mandatory. Value should be consumer
locationURI	URI	Http URL where this proxy endpoint will be exposed so that the ESB clients can access the proxy service.	Mandatory
defaultMEP	URI	The MEP URI by which clients interact with the consumer component	Not Mandatory
soap	boolean	If it is true, the component will parse the SOAP envelope and pass the contents to the NMR	Not Mandatory. Default value is false.
wsdlResource	Spring Resource	If it is set, the WSDL will be retrieved from this configured Spring resource.	Not Mandatory

Thus, the locationURI attribute in the servicemix-http consumer refers to the Http URL where this proxy endpoint is exposed, so that the ESB clients can access the proxy service. Later we will look at how to generate static client stubs out of this proxy URI.

servicemix-http as provider: While configuring the provider, there are a few aspects to be taken care of with respect to the WSDL. If we have the sample WSDL as shown as follows:

Sample Code

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:impl="http://AxisEndToEnd.axis.apache.
binildas.com" targetnamespace="http://AxisEndToEnd.axis.
apache.binildas.com">
<wsdl:service name="IHelloWebService">
<wsdl:port name="HelloWebService"
binding="impl:HelloWebServiceSoapBinding">
<wsdlsoap:address location="http://localhost:8080/
AxisEndToEnd/services/HelloWebService"></wsdlsoap:address>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>

Now, while configuring the provider component you need to ensure that the service (IHelloWebService) and the endpoint (HelloWebService) match the service name and port elements of the WSDL that you use to correctly return the WSDL for the endpoint. Moreover, the service name will use the targetNamespace for the WSDL (http://AxisEndToEnd.axis.apache.binildas.com).

A sample servicemix-http provider component configuration is shown as follows:

Sample Code

<http:endpoint endpoint="HelloWebService"
soap="true" role="provider" service="test:IHelloWebService"
wsdlresource="http://localhost:8080/AxisEndToEnd/
services/HelloWebService?WSDL"
locationuri="http://localhost:8080/AxisEndToEnd/
services/HelloWebService" soapaction="></http:endpoint>

The following table the gives the explanation for the main configuration parameters:

Attribute Name	Type	Description	Mandatory or Not
service	QName	Service name of the exposed endpoint	Mandatory
endpoint	String	Endpoint name of the exposed endpoint	Mandatory
interfaceName	QName	Interface name of the exposed endpoint	Not Mandatory
role	String	Whether a consumer or a provider	Mandatory. Value should be provider
locationURI	URI	Http URL of the target service.	Mandatory

Attribute Name	Type	Description	Mandatory or Not
soap	boolean	If it is true, the component will parse the SOAP envelope and pass the contents to the NMR	Not Mandatory. Default value is false.
soapAction	String	The SOAPAction header to be send over HTTP when invoking theweb service	Not Mandatory. Default value is "".
wsdlResource	Spring Resource	If it is set, the WSDL will be retrieved from this configured Spring resource.	Not Mandatory
