[@0] All commands assume a Linux environment. =${HOME}= refers + to the home directory of the user, and =${DEV_HOME}= refers to + where the git repository has been cloned to. + 1.

Change to where the code is: + : cd ${DEV_HOME}/source/java/org/gibiris/javaBootcampNoEclipse + 2. Compile the files: + : javac *.java + 3. Check the errors. If you see the message =error: package + javax.servlet does not exist=, then look at your =CLASSPATH= + setting, as dependend libraries are missing. + 4. Fix your =CLASSPATH= and compile the java files: + : export CLASSPATH=/usr/share/java/tomcat8-servlet-api.jar:${CLASSPATH} + : javac *.java + 5.
