I deploy a war file called aex.war in the $CATALINA_HOME/webapps/ directory. I start Tomcat and the war file explodes as it should. I use the browser to hit my application http://localhost:8080/aex/index.html and I get this error
I checked the logs, and it seems that when I start tomcat this message is given in the log
This explain the browser error. Here is the previous application error in the log, which this message above is referring too.
