Hi,
we are using Jboss connection pool for creating the connection to remote database server and when there is some network issue we are not able to connect to DB.
at the time we are use to manually flush the connection through JMX-console using Flush function. but yesterday we found the issue for Flush function was not working.
we checked in Jboss server logs we found below error:
2017-09-18 01:40:14,865 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/App].[jsp]] Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
we are using Jboss-4.0.5
Please let me know why it was occurred.
