ELS Login via Admin Client gives error - null

Options
Hi All,

We are on RHEL7, OpenJDK 11.0.6, Tomcat 8.5.55
We have installed OTDS, AS, CS and ELS on the same machine (DEV env)

CS - installation is complete and works with OTDS authentication
AS - installation is complete and working
OTDS - is also up and running

When we try to login to ELS via Admin client we get the following error


The error in ot-elib



As per few KB article, cws and ot-elib web.xml is updated to point to the correct fqdn/
Enterprise library extension and EL search extension modules are installed.
Enterprise library volume is created and present under SOV
/otcs/cs.exe?func=elsadmin.repeatcustomstep executed to make sure the custom steps are executed.


Any help will be appreciated.

Rinita
