Possible result for an incorrect Java installation. Pay particular attention to the need for a correct pathĮnvironment variable. If you enter either command and get something similar to that shown inįigure 4, you need to go back and troubleshoot the installation of the Java Getting a correct response for both tests is an indication that the Java JDK is Java HotSpot(TM) Client VM (build 23.25-b01, mixed mode, sharing) Java(TM) SE Runtime Environment (build 1.7.0_25-b17) The folder named bin should contain a file namedĮnter the java command shown in Figure 3. The format of this path will vary somewhat depending on which operating In the event that you do not get this response, you will probably need to setĮnvironment variable on your computer to point to something similar to theįollowing: C:\Program Files (x86)\Java\jdk1.7.0_25\bin Type the javac command shown in Figure 2 immediately to the right of Should be a blinking cursor immediately to the right of the ">".

The JDK can be downloaded for free from Oracle at (Note that the JDK isĪlready installed on the computers in the computer labs at NRG.) (JDK) must be installed on your computer.

Running under a different operating system, you will need to translate these These instructions assume that you are running under Windows.

Also, take some time to try to figure out what the code is doing. Then, modify the code to send the email to my address. To test, you may want to send yourself an email first to make sure that your mail is being sent correctly. For lab 1, make sure the output looks correct. Note: If you are using multiple classes in your program you will need to compile all of the files and then run the program by using the classname of the class that contains your main method.

Do an "ls" (or "dir" if you are using windows) to verify the class file is there. If the compiler doesn't spit out any errors, it should have generated a ".class" file. Compile by typing javac filename where filename is the name of the file.Setting the path depends on a number of things. If you type "javac" and the command is not recognized, the compiler is not in your path. Make sure that the java compiler is in your PATH.Note: I am assuming that you are not using packages. cd into the directory where your code has been saved.For your first lab you should save the code as "smtpClient.java". If you are writing a class named Test, your file MUST be named Test.java. Important: The name of the file must be the class name with a. Use this as an opportunity to learn more about Java! But, you should be able to understand enough to modify the necessary portions for the assignment. We will talk more about sockets in class. You may not be able to fully understand all of the code. But, remember that you have a couple of things to modify. For your first lab, copy and paste the code from the tutorial web page. Open up your favorite text editor (I like emacs) and write your code.For example, if you have a package named "networks.webserver", all files in that package MUST be in a directory named "webserver" that is in a directory named "networks". But, if you do use packages, you must create a directory tree that matches your package name.

For lab 1, you don't need to worry about packages. This step is more important if you are using packages.
