Issue/Introduction

When attempting to start the CA Mainframe Application Tuner (MAT) GUI why are we getting a 505 error?

Environment

Release:
Component: MATUNE

Resolution

The client was running the GUI from http://ourhostname:51914/mat11. 

What occured to us is that they should be running it from mat11/mat 

When CA ran with just mat11 we get a 500 error. 

The client tried running from http://ourhostname:51914/mat11/mat and they were OK.
