Issue
When configuring an Access Fulfillment Express (AFX) Connector for RESTful Web Services, the Add Application Role to Account capability has the following default Request Header settings:
Default Configuration

Headers

Name

Content Type

Accept

Value

application/xml

Accept


However, when AFX is processing the response from the RESTful Web Service, a message with the following properties and error message may be returned. 
Message properties:
INVOCATION scoped properties:
INBOUND scoped properties:
Connection=false
Content-Length=389
Content-Type=application/xml; charset=UTF-8
Date=Wed, 12 Oct 2016 03:20:21 GMT
Keep-Alive=false
The below error may be logged during parsing of the http web service response: 
<Response timestamp="2016-10-12T14:20:36.035+11:00">
<status>
<code>2</code>
<brief>Failure - Error processing RESTful web service response</brief>
<detailed>Error processing RESTful web service response: java.lang.IllegalStateException: Expected application/xml but received application/xml; charset=UTF-8</detailed>
</status>
</Response>
Cause

The RESTful Web Wervice is providing a Content Type of: application/xml; charset=UTF-8, but the expected value is just: application/xml.

To enable AFX DEBUG, please review the following articles:

When AFX DEBUG is enabled, the following messages may also be returned in the Connector log:

2016-10-12 09:23:45.675 [DEBUG] org.mule.module.scripting.transformer.ScriptTransformer:125 - Object after transform: Error processing RESTful web service response: java.lang.IllegalStateException: Expected application/xml but received application/xml; charset=UTF-8 
2016-10-12 09:23:45.703 [WARN] org.mule.transport.jms.JmsMessageUtils:269 - Header: Content-Type is not compliant with JMS specification (sec. 3.5.1, 3.8.1.1). It will cause problems in your and other applications. Please update your application code to correct this. Mule renamed it to Content_Type


NOTE

For AFX version 7.0.1 and above, the Connector logs are located in the $AVEKSA_HOME/AFX/esb/logs directory, and have the following prefix;

  • esb.AFX-INIT.log
  • esb.AFX-CONN-<connector name>.log 
  • esb.AFX-SETTINGS-<connector name>.log

For AFX versions 7.0.0 and 6.9, the Connector logs are located in the $AVEKSA_HOME/AFX/mule/logs directory, and have the following prefix;

  • mule-ee.log
  • mule.AFX-CONN-<connector name>.log
  • mule.AFX-SETTINGS-<connector name>.log 
Resolution
So that it meets the JMS specification (sec. 3.5.1, 3.8.1.1), the RESTful Web Service needs to send:
 
Content-Type=application/xml
 
instead of:
Content-Type=application/xml; charset=UTF-8
 
This is in accordance with the message: 
org.mule.transport.jms.JmsMessageUtils:269 - Header: Content-Type is not compliant with JMS specification (sec. 3.5.1, 3.8.1.1).
It will cause problems in your and other applications.
Please update your application code to correct this.
Mule renamed it to Content_Type
Workaround
It may not be possible to correct the Content-Type being sent by the RESTful Web Service.  In this situation, RSA Identity Governance and Lifecycle allows the expected Content-Type to be adjusted.

To resolve the problem, update the Request Header Content-Type in the Connector Capabilities, so that is matches what is being sent by the RESTful Web Service; for example,

set Content-Type to: application/xml; charset=UTF-8
