Some hoare.cs.umsl.edu Notes

1. web.xml - Remember to go to WEB-INF and touch web.xml after modifying a .java file and recompiling it or making other changes in your webapp. We will have a more complete discussion on deploying webapps
    
   
2. bash and Directory setup notes.
    
   
3. "cd tomcat" vs. "gotoTom" a directory name issue.
   When you do either you go to the same directory. However the directory name is computed differently.

   [j-siegel@hoare7 ~]$ pwd
   /classes/Java/j-siegel
   [j-siegel@hoare7 ~]$ cd tomcat
   [j-siegel@hoare7 tomcat]$ pwd
   /classes/Java/j-siegel/tomcat
   [j-siegel@hoare7 tomcat]$ ls W*
   Whoisit.html  WhoJSP.html
   
   WEB-INF:
   classes  lib  myothertags.tld  mytags.tld  web.xml
   
             AND
   
   [j-siegel@hoare7 ~]$ pwd
   /classes/Java/j-siegel
   [j-siegel@hoare7 ~]$ gotoTom
   [j-siegel@hoare7 j-siegel]$ pwd
   /var/lib/tomcat/webapps/j-siegel
   [j-siegel@hoare7 j-siegel]$ ls W*
   Whoisit.html  WhoJSP.html
   
   WEB-INF:
   classes  lib  myothertags.tld  mytags.tld  web.xml
