[Ejbca-develop] externalra_gui/ error

[<ha...@nc...>]

Dear sir

I have setup an externalRA server with the GUI ,
the GUI doesn't use HTTPS, just normal HTTP.
And also setup the RA Service worker at the CA Side. But I encountered the
following issue:
When I open the RA-Gui page and select Create Browser Certificate, and
input a user-name and password, it waits for the RA wait time and then
responds saying "CA did not respond"
the logs in the CA Server say the following
java.net.ConnectException: Connection refused
-ERROR [SchemaUpdate] could not get database metadata
javax.resource.ResourceException: Unable to get managed connection for
RAMessage1DS
 com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications
link failure
- ERROR [MessageProcessor] Misconfigured CA Name in RAService


  your help will be very much appreciated.
