My application produces an internal server error, running on tomcat it prints a stacktrace with the given error. On Oracle it hides the error and post it to application.log.
Is it possible to change this setting via the deployment descriptor?
500 Internal Server Error
Servlet error: An exception occurred. The current application deployment
descriptors do not allow for including it in this response.
Please consult the application log for details.
You can define error handling pages in your web.xml:
<error-page>
<error-code>500</error-code>
<location>/WEB-INF/pages/500.jsp</location>
</error-page>
If the error code is explicitly set by your application make sure it uses response.sendError() and not response.setStatus() because the latter will ignore your custom error pages defined in web.xml
p.s By googling your error message I assume that this is a Java web application running on OAS
