Environment

Release : 12.0.X, 12.1.X, 12.2.X, 12.3.X

Component : AUTOMATION ENGINE

Cause

Wrong WebSphere configuration

Resolution

Incorrect WebSphere configuration: 

Check your WebSphere configuration according to the version of Automation Engine you are on. 

E.x., documentation reference for 12.2 (WebSphere section):

https://docs.automic.com/documentation/webhelp/english/ALL/components/DOCU/12.2/AWA%20Guides/help.htm#Installation_Manual/AWI/InstallingAWI.htm%3FTocPath%3DInstalling%7CManual%2520Installation%7CInstalling%2520the%2520Automic%2520Web%2520Interface%7C_____0 

In most of the cases, the following step is misconfigured: 

WebSphere section 3.5.2:

5. In Custom Properties do the following:

1. Set the com.ibm.websphere.webservices.DisableIBMJAXWSEngine property to true.

If it does not already exist, you can create it clicking New.

2. Set the javax.xml.bind.JAXBContext property to com.sun.xml.internal.bind.v2.ContextFactory - make sure that you column name in the WebSphere configuration is 'javax.xml.bind.JAXBContext' and NOT 'javax.xml.bind.JAXBContext property' - that will cause the error described above.
