I changed the password for db username = postgres
It appears that JasperReports had the old password in some config(s) file and now it doesn't work.
What do I need to do here? I'm guessing I need to find the relevant config files and update them? If so, which ones? If not, what do I do?
You need to change the JNDI connection to the repo, that is defined in <TOMCAT>/webapps/jasperserver-pro/META-INF/context.xml
There look for the JNDI connection called jdbc/jasperserver and change the password to the new one
We had the same problem with the WAR installation.
The WAR installation explodes with multiple config files and its not an easy thing to find the relevant files which needs to be modified.
We had to start from scratch and explode the WAR with the required password and then it worked.
