![]() As noted below, version 2 of WinSCP uses a couple of components from PuTTY. Windows users should use a secure file transfer program like WinSCP (also available in the 'Extras' directory). To connect to ECS servers, you should use a program like PuTTY (available in the 'Extras' directory).Īgain, if you are on a Unix-type box, scp should be installed, and you should use this in preference to ftp 'man scp' will tell you all you need to know to use it properly. On the other hand, if you are on a Windows system, you'll have to choose a third-party product to keep your connections secure. (If you're not sure how to use it, 'man ssh' should tell you all you need to know.) By using this rather than telnet you ensure that your username/password is never sent in the clear. If you are on a box running Unix of some flavour (a Linux or one of the BSDs, for example), ssh should be installed by default. There are several simple steps that you can take to avoid this happening. Unfortunately, if you use programs such as the telnet and ftp clients that come bundled with Windows, you will be sending your username and password across the network in the clear - this means that others could, in principle, pluck your username and password out of network traffic. If you are working from home it is often very useful to be able to log into the university systems remotely, or transfer files back and forth. ecs100.tmpl: Move this file into C:\Program Files\BlueJ\lib\english\templates\newclass\.ecs100.jar: Move this file into C:\Program Files\BlueJ\lib\userlib\.(The instructions below assume you installed BlueJ into C:\Program Files\BlueJ. There should be five files in the BlueJ directory in addition to the BlueJ installer file. You need to copy some files from the CD into your BlueJ installation area. Once you have installed BlueJ, you need to customise your BlueJ environment for ECS courses. This should put BlueJ in your Start menu. To install BlueJ, open the CD directory, open the 'BlueJ' directory, and run (double-click) the installer, which is called 'bluej-314.msi'. (While it is possible to do these things with a combination of a simple text editor and the command-line, a development environment makes the process a lot less painful.) We have provided the free BlueJ integrated Java environment. Now that you've installed Java, you need to install an editor - something that will let you write, compile, run and debug programs. ![]() Installing and Customising the Java Editor Once this is done, and you've rebooted, you should have successfully installed Java. ![]() If you're using a more modern flavour of Windows (such as Win7 or WinXP), you'll have to go to Start->Settings->Control Panel->System, click on the 'Advanced' tab, and choose 'Environment Variables'. How you do this depends on what version of Windows you're running. Now, the operating system needs to know where to look to find Java - that is, the environment variable PATH has to be set. Simply open the directory you installed Java into, and in another window open the CD directory, and copy the 'docs' directory into it. Next, it's a good idea to copy the Java documentation onto your computer. ![]() ![]() You should take note of where you choose to install Java - you'll need to know for the next steps. To install JDK 8 update 31 (the version currently used in ECS courses), open the CD directory, open the 'Progs' directory, and then run the installation program, 'jdk-8u31-windows-圆4.exe'. There is also a copy on the CD in the docs/ directory. You can look at Oracle's documentation about the version currently used in COMP courses (8.0) on the web if you wish. The first step in setting up your computer to compile and run Java programs is to install the Oracle Java Development Kit (abbreviated as JDK). Installing and Customising the Java Editor. ![]()
