h1. Features

The SOAP component is a Binding Component (BC) which enables to interact with external SOAP Web Services and to expose JBI services as SOAP Web Services.

In provider role, when a JBI MessageExchange is sent to a ServiceEndpoint (mapped to a Web Service), it is transformed into a SOAP message and sent to the linked external Web Service. In consumer role, when a SOAP message is received on an exposed Web Service, it is transformed into a JBI MessageExchange and sent to the corresponding JBI ServiceEndpoint.

The SOAP component is based on Apache Axis2 v1.6.3 ([http://ws.apache.org/axis2/|http://ws.apache.org/axis2/]) and Mortbay Jetty v9.2.12.v20150709 ([http://www.eclipse.org/jetty/]). It provides the following features:
* Expose JBI Services as SOAP Web Services
* Expose SOAP Web Services as JBI Services
* Handle SOAP attachments (MTOM):
** the attachments of the incoming SOAP message are placed into the JBI message as attachments,
** the JBI attachments are placed in the outgoing SOAP message as attachments.

{warning}This version must be installed on Petals ESB 5.0.0+{warning}

{info}
If you want more details about SOAP, you can consult this W3C specification: [http://www.w3.org/TR/soap/|http://www.w3.org/TR/soap/].

All attachment are processed by using XOP rules. (XML-binary Optimized Packaging: [http://www.w3.org/TR/xop10/])

h1. Provide a Web Service access in the ESB (SOAP over HTTP(S))

In provide mode, the component exposes an external Web Service in the JBI environment to send SOAP requests to the external Web Service.

{info}
The HTTPS configuration is located at the service-unit level to be able to use different certificates with different external webservices.
{info}

{warning}
Only JKS keystore and truststore are supported in the HTTPS mode.
Moreover, the key password and the keystore passwords have to be the same.
{warning}

h2. Usage

The SOAP component can expose an external Web Service as a JBI service endpoint by deploying a Service Unit on it:
\\
{center}
*Provides an external Web Service as a JBI service*
\\ !petals-bc-soap-x.x-provider..png|border=0,width=500,height=285!
{center}

When a message is received on a SOAP linked endpoint from the JBI environment, it is transformed into a SOAP message and sent to the Web Service. The address of the Web Service to send the SOAP message to is defined in the address extension of the deployed Service Unit.

The SOAP message is created like this:
* The JBI message payload is wrapped in the SOAP body
* The JBI message attachments are used to create SOAP ones
* The JBI message exchange operation is used to create the SOAP action
* The JBI MEP is used to determine the SOAP MEP

The external Web Service is called and the SOAP response is processed and returned to the JBI environment.

h3. Service Unit content

The Service Unit has to contain the following elements, packaged in an archive:
* The META-INF/jbi.xml descriptor file as described above,
* An optional imported WSDL file describing the partner service

h1. Exposing an internal JBI service endpoint as a Web Service (SOAP over HTTP(S))

In consumer mode, the component exposes an internal JBI service outside the bus to transfer incoming SOAP requests to the internal service.

{info}
The HTTPS configuration is located at the component level because only one certificat is needed to expose the Petals service as a HTTPS web-service.
{info}

h2. Usage

The petals-bc-soap component can listen incoming SOAP messages and send messages to a JBI service endpoint by deploying a Service Unit on it. The component consumes the JBI service:
\\
\\
{center}
*Consumes a JBI service on a SOAP message*
\\ !petals-bc-soap-x.x-consumer.png|border=0,width=500,height=285!
{center}

The service-name Service Unit extension value will be used as Axis2 service name.

When a SOAP message is handled by the component, it is transformed into a JBI Message and sent to the JBI service endpoint configured in the Service Unit. The JBI message is created like this:
* The JBI operation is resolved (see [Operation Resolving|#op-resolving]).
* Copy the SOAP body into the JBI one.
* Put the SOAP attachments into JBI ones.
* Put the SOAP headers into the protocol header JBI message property.

By default, the component is configured to handle URI with the [http://localhost:8084/petals/services/]<service-name> (or 8083 for HTTPS) pattern (this URI can be configured in the [SOAP component configuration|#componentConfiguration]). It also handles ?wsdl calls; the WSDL description is retrieved from the endpoint and sent back to the consumer.

By default, the list of HTTP services is available at [http://localhost:8084/petals/services/listServices] (or 8083 for HTTPS) URI (it can also be configured in the [SOAP component configuration|#componentConfiguration]).

{warning}
If you plan tests with JAX-WS Reference Implementation, please use the JDK one (not the JRE one), otherwise MTOM attachments will not be handled properly.

h3. Service Unit content

The Service Unit has to contain the following elements, packaged in an archive:
* The META-INF/jbi.xml descriptor file as described above

h1. SOAP over JMS

By configuring the SOAP component and a Service Unit, it is possible to consume an internal JBI service.

{warning:title=Warning}
This feature is currently only supported in consumer mode with the operation with the MEP InOnly.
{warning}

h2. Usage

The petals-bc-soap component can receive JMS messages from a JMS queue and send SOAP messages (contained in the JMS body message) to a JBI service endpoint by deploying a Service Unit on it. The component consumes the JBI service.

It enables to support the following scenario: A JMS publisher sends a message to a JMS server and the SOAP component consumes the JMS message which contains a SOAP envelope in its body:

{center}
!petals-bc-soap-x.x-soap_over_jms.png|border=1,width=500,height=285!
*Consumes a JBI service on JMS message (containing SOAP envelope)*
{center}

The service-name Service Unit extension value will be used as Axis2 service name.

When a JMS message is handled by the component, the SOAP envelope (in its body) is extracted by Axis, is transformed into a JBI Message and sent to the JBI service endpoint configured in the Service Unit. The JBI message is created like this:
* The JBI operation is created from the SOAP action.
* Copy the SOAP body into the JBI one.
* Put the SOAP attachments into JBI ones.
* Put the SOAP headers into the protocol header JBI message property.

h2. Configuration

h3. JMS server

A JMS server must be started before starting the BC SOAP component (if the JMS transport layer is configured). The compatible JMS servers are Joram and Apache ActiveMQ.

h3. Shared library

A shared library corresponding to the JMS server (SL-JMS-Joram or SL-JMS-ActimeMQ) must be installed in Petals ESB before installing the BC SOAP component in Petals ESB.

h3. Component descriptor

The JMS transport layer must be set in the component jbi.xml file (cf [SOAP component configuration|#componentConfiguration]):

</jbi:jbi>
{code}

When the SU is started, a queue is created on the JMS server by the SOAP component if it does not exist. The name of the queue is the value of the parameter soap:address or soap:service-name.

When a message is sent to the JMS queue, it is received and treated by the SOAP component.

h1. Operation resolving: Mapping from URI, SOAP/WSA Action, Document/Literal-wrapped pattern and RPC/Literal pattern

The SOAP BC serves many SOAP services to the exterior (defined by JBI Consumes in the deployed SU) at the same time.
While it is not difficult for it to know which service is concerned by a request (because its name is in the called URI), determining the concerned operation is more complex.

There exists many ways to approach this question (see for example http://www.ibm.com/developerworks/library/ws-whichwsdl/).

In Petals we support the most common ones (those that are provided by Axis2) in that order:
- URI: if the service call's URI has the form: .../services/MyService/myOperation then the operation will be myOperation.
- SOAP/WSA Action: if the http header contains a SOAP Action or the SOAP message header contains a WSA Action, then it will be used to resolve the operation as defined in the WSDL.
- Document/Literal wrapping: from the first element's QName of the body, the operation that contains the message that contains the part that refers to this element is used.
- RPC/Literal: from the first element's localName (and not full QName) of the body, the operation that has the same name will be used.

For the last two, in case of ambiguity, the call will fails.

h1. Advanced usages

h2. Getting log traces from the underlying layers

The Petals BC SOAP is based on [Axis2|http://axis.apache.org/axis2/java/core/] and [Jetty 9.2|http://www.eclipse.org/jetty/documentation/9.2.10.v20150310]. To get log traces from these underlying layers, just add something as the following configuration to the Petals ESB logging configuration:
{code}
Petals.Container.Components.level=MONIT
# The following line enable debug traces from the BC SOAP itself
Petals.Container.Components.petals-bc-soap.level=FINE
# The following line enable debug traces from the underlying layer 'Jetty'
org.eclipse.jetty.level=FINE
# The following line enable debug traces from the underlying layer 'Axiom'
org.apache.axiom.level=FINE
# The following line enable debug traces from the underlying layer 'Axis2'
org.apache.axis2.level=FINE
org.apache.ws.security=FINE
org.apache.rampart=FINE
org.apache.commons.httpclient=FINE
{code}

h1. Know problems

h2. No HTTP/WS request is processed

When you try to invok a web-service with your favorite client, you get a time out instead of a standard response. A possible cause is configuration error of the HTTP thread pool. Check your configuration: the HTTP thread pool max size must be upper than the HTTP acceptor number, see [the component configuration|#componentConfiguration].

h2. Error invoking a service with 2\+ attachments from SoapUI

If you get an error invoking a service with at least two attachments from SoapUI, check that you have enabled the multi-part mode in the SoapUI properties of the request.

h2. "sec_error_inadequate_cert_type" appears when trying to get services list available through SSL on the HTTPS client side

If get the error "sec_error_inadequate_cert_type" using a browser to get available services through SSL, check your SSL configuration of your BC SOAP. Probably, you inverse certificates usage: You configure the public key of the server instead its private key.

h2. "sec_error_bad_cert_alert" appears when trying to get services list available through SSL on the HTTPS client side

You get this error on the HTTPS client side when the client authentication is *enabled* on the server side and no or bad certificate is available on the client side.

h2. Receiving fault "WSDoAllReceiver: security processing failed (actions mismatch)" invoking a webservice secured by WS-Security

The following fault returned by the BC SOAP to our client means that you have not set all required WS-Security headers. Check you client configuration against WS-Security configuration expected by the webservice.
{code}
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<soapenv:Fault>
<faultcode>soapenv:Server</faultcode>
<faultstring>WSDoAllReceiver: security processing failed (actions mismatch)</faultstring>
<detail>
...
