ADD SOAP HEADER INTERCEPTOR

This interceptor adds a SOAP header to incoming request using the Java DOM API.

RUNNING THE EXAMPLE

To run the example execute the following steps:

1. Goto the examples/soap11/add-soap-header directory
2. Run below command

 mvn package

3. Execute service-proxy.bat or service-proxy.sh
4. Open a second terminal
5. Run below command

curl -d @soap-message-without-header.xml http://localhost:2000 -H "Content-Type: application/xml"

6. On the console you will see that a security XML-element gets added to the request of the body

HOW IT IS DONE

Using maven, we create a jar file and copy the compiled jar file into the libs directory of membrane to make the new interceptor available to the router.

In the proxies.xml file, we define a name for our interceptor and write its fully qualified name, so we can use our interceptor on `. You can see it in the line below.

<spring:bean id="headerAddInterceptor" class="com.predic8.AddSoapHeaderInterceptor" />

Again in the proxies.xml file inside <serviceProxy> tag you can see that we added the interceptor using the beanname we defined above.

<serviceProxy name="echo" port="2000">
  <interceptor refid="headerAddInterceptor"/>

The add header interceptor checks if the content of the request is xml and the existence of a Header element. If both conditions are met it adds a Security element to the SOAP header. Have a look at the AddSoapHeaderInterceptor source code as well.

Also, you might notice the groovy interceptor. This is just used for sending a request back. Usually there is a target-Element instead.
