Tomcat directory introduction:
\bin stores the executable files for starting and shutting down Tomcat.
\conf stores Tomcat configuration files
\lib stores library files
\logs stores log files
\temp stores temporary files
\webapps stores web applications
\work stores Jsp converted Servlet files
Shudown in the bin directory is used to close tomcat; startup is used to open tomcat.
Pay special attention to the jsp-api.jar package and servlet-api.jar, which will be used later.
