How do I get the Java software and files I need?

Download the Java SE Development Kit (JDK) 8, Java SE 8.0 API Documentation, and Java SE Runtime Environment (JRE) 8 Update XX here. You do not need to download the bundles that include JavaFC, Java EE, or Netbeans. You only need the JDK that includes the JRE and command-line development tools. After installation, the files will be located on the C drive, usually at C:\Program Files\Java\jdk1x.

Download your Java editors/IDEs for Windows:

Option 1: Crimson Editor is probably the best option unless you have a specific reason for using the Eclipse Integrated Development Environment (IDE) listed below.

  1. Go to
  2. Choose the option for Download from the left-hand navigation menu.
  3. Choose the most recent release from one of the download mirrors.
  4. Execute the file you just downloaded by double-clicking on it.
    1. Read the License Agreement and click on the button labeled I Agree.
    2. When asked what components to install, you can leave the default settings.
    3. Install Location can be left as default.
    4. When the install finishes, click the button labeled Close.

Option 2: Eclipse Integrated Development Environment (IDE), which is optional for this class at the discretion of the instructor.

  1. Go to
  2. Choose the option Eclipse IDE for Java Developers. This downloads a zip file.
    1. For basic Java classes, we use Eclipse IDE for Java Developers, which does not include Java EE capabilities such as Servlets and JSPs.
    2. For Java EE classes, download Eclipse IDE for Java EE Developers.
  3. Unzip/Extract the downloaded file to C:\. The installation is a simple unzip to C:\ (Eclipse does not "install"—you run it directly from eclipse.exe, which will be in C:\eclipse after the unzip).
How do I get the Oracle software and files I need?

You need to have full administrative access to Oracle 10g or 11g. If you do not, you can download the Oracle Database Express Edition for either 32- or 64-bit OS here. You will need to register for a free account to gain access to the download.

You will also need to install Oracle SQL Developer for either Windows 32- or 64-bit platforms. Download "Windows 32-bit - zip file includes the JDK1.6.0_35" here, or download " Windows 64-bit with JDK 8 included" here.

Download the class files here. Create a directory on your hard drive named "Webucator" that can be found easily and extract the files to the folder you just created. If you are using XAMPP (e.g., for PHP classes), you must place the Webucator folder on the C:\xampp\htdocs folder.

Unlock the HR account using the following steps:

  1. In SQL Developer, log in using this connection:
    1. Connection name: system
    2. Username: system
    3. Password: system (this should be the password you created when you installed Oracle)
  2. Open the HR_Unlock_Account.sql file from your class files.
  3. Click on the second green play button (F5) to execute the SQL query.
  4. To continue setup, click on the green + under the Connections tab, and add the criteria below:
    1. Connection Name: hr
    2. Username: hr
    3. Password: hr
    4. Click on Connect, and a worksheet should open up on a tab that's labeled "hr"
  5. Now that you're connected to HR, you're ready to test.
    1. Enter the following in the worksheet: select * from regions.
    2. Click on the green arrow to execute your code.
    3. If you get back 2 columns and 4 rows, then you are all set.
