[ http://jira.jboss.com/jira/browse/JBWS-1297?page=comments#action_12346789 ] Jason T. Greene commented on JBWS-1297: --------------------------------------- The fault bean is already discovered or built by the JSR181MetaDataBuilder. You can get the class by just saying faultMetaData.getFaultBean(). You then only have to check if the exception you are trying to (un)marshall to/from can take a fault bean. So here is the order of preference. Marshalling a Exception 1. Look for getFaultInfo(), call and marshall the instance that is returned if exists 2. Otherwise, instantiate a new fault bean, and copy each property individually. Unmarshalling an Exception 1. Look for a contsturctor that takes the fault bean, if present pass the fault bean instance to the constructor 2. Otherwise, instantiate a new Exception using the values from the fault bean instance. The order will be defined on the propOrder attribute of the @XmlType annotation. That said, I realize that In order to access the properties on the JAXB fault bean, we are going to need to use something similar to the accessor API that is used for (un)marshalling wrapped request/response structures. I am going to create a separate issue for this, assign it to myself and link it as a dependency. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
