I am running Tomcat in unix server. I am starting the Tomcat using some shell script, am not facing any problem in that. But i wanted to see the error messages which are throwing from my application, my question is how can i see the error message in the Unix? In windows i can see the Tomcat console, from there i can able know the error message. In Unix how to know the error message? Where i can get the printStackTrace error messges?
