Suppose: Web Application Directory: "example" What is easy: localhost:8080/webapps/example/intro.html What I want: localhost:8080/example/intro.html Solution: There's a hint on the welcome page when you enter: localhost:8080 which says, It works ! If you're seeing this page via a web browser, it means you've setup Tomcat successfully. Congratulations! This is the default Tomcat home page. It can be found on the local filesystem at:  /var/lib/tomcat7/webapps/ROOT/index.html Tomcat7 veterans might be pleased to learn that this system instance of Tomcat is installed with  CATALINA_HOME  in  /usr/share/tomcat7  and  CATALINA_BASE  in  /var/lib/tomcat7 , following the rules from  /usr/share/doc/tomcat7-common/RUNNING.txt.gz . Therefore, you can install your own web applications under this directory - /usr/share/tomcat7/webapps - to access

source: Question: I am just curious to know, what happens when System.out.print() is called in a servlet? Where does it write the text? I cannot find any file named stdout_<date>.log on my filesystem. Answer: It depends on your servlet container. For  Tomcat  : When running Tomcat on unixes, the console output is usually redirected to the file named catalina.out. The name is configurable using an environment variable. (See the startup scripts). Whatever is written to System.err/out will be caught into that file. for example /var/log/tomcat7/catalina.out

source:  http://en.kioskea.net/faq/2287-fstab-adding-spaces-in-the-mount-point-path Question: File System table  or  FSTAB  refers to system configurations which are usually used on a Linux environment. Sometimes users may have problems with  adding spaces  in mouth point path. This mainly happens because here  various options are separated by a space . To get rid of this problem, one has to type "0/040" instead of space  in the configurations. After that,  adding spaces  in mouth point path should not be an issue. Answer: This limitation is easily bypassed by typing "\ 040" instead of a space in the configuration file. Example: /dev/sda1 /mnt/first\040disk ext3 options 0 0 UUID=9d49c47e-91c4-49f0-806c-bc97910ad5eb /home/jinuine/VirtualBox\040VMs ext4 defaults 0 2

source:  http://askubuntu.com/questions/159992/how-to-mount-ext4-partition Question: How do I mount an ext4 partition as my user account so I wouldn't require root access to r/w on it? I used  -o uid=flint,gid=flint  on the  mount  command but I keep getting mount: wrong fs type, bad option, bad superblock on /dev/sda7, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Another thing, I want avoid using  udisks  for now as it doesn't let me mount to my specified mount point name. Answer: You don't. The files in the fs are owned by whoever owns them, and you can not change that at mount time. Instead you need to change the permissions to give yourself access with  sudo chown yourname.yourname /path/to/mount . On a freshly formatted filesystem, the root directory is owned by root, so you will need to change it and from then on, you will be able to cr...
