CA WA DE Webclient does not run REST API commands

Products

• CA Workload Automation DE

Issue/Introduction

The Web Client and Java process are running, but it's not responding to API calls.    

Environment

Release: CA WA DE Web Client 12.1/ 12.2

Component: Web Client

Cause

Make sure the Web Client port (e.g. 8443) is not blocked.  If the port is not known then look for the "Connector port" string in <install_dir>/apache-tomcat/conf/server.xml file.

E.g.

Connector port="8443" protocol="HTTP/1.1"

Check the permissions on the directories of the Web client.

Resolution

Open the port that Web client is using to listen for REST API calls (default is 8443).  The port must be open for all incoming requests from outside clients.

You must login once via browser to the Web client for REST to work.  This is needed for the REST calls to know which DE server to contact.
