| Preparing Eclipse |
| </h1> |
| <p> |
| In this section, you will verify that Eclipse is properly set up for Java development. |
| </p> |
| <p> |
| The following is assumed: |
| </p> |
| <ul> |
| <li> |
| You are starting with a new Eclipse installation with default settings. |
| </li> |
| <li> |
| You are familiar with the basic Eclipse workbench mechanisms, such as views and perspectives. |
| </li> |
| </ul> |
| <p> |
| If you're not familiar with the basic workbench mechanisms, please see the |
| <a href="PLUGINS_ROOT/org.eclipse.platform.doc.user/gettingStarted/qs-01.htm">Getting Started</a> chapter of the Workbench User Guide. |
| </p> |

| Verifying JRE installation and classpath variables |
| </h2> |
| <ol> |
| <li> |
| If you still see the Eclipse Welcome page, click the arrow icon to begin using Eclipse. |
| </li> |
| <li> |
| Select the menu item |
| <a class="command-link" href='javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.ui.preferencePages.Workbench)")'> |
| <img src="PLUGINS_ROOT/org.eclipse.help/command_link.svg" alt="Goto workbench preferences"> |
| <b>Window > Preferences...</b></a> |
| to open the workbench preferences. |
| </li> |
| <li> |
| Select the |
| <a class="command-link" href='javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.jdt.debug.ui.preferences.VMPreferencePage)")'> |
| <img src="PLUGINS_ROOT/org.eclipse.help/command_link.svg" alt="Goto the installed JREs preference page"> |
| <b>Java > Installed JREs</b></a> |
| preference page to display the installed Java Runtime Environments. Confirm |
| that a JRE has been detected. By default, the JRE used to run the workbench will be used to build and run |
| Java programs. It should appear with a checkmark in the list of installed JREs. We recommend that you |
| use a Java SDK instead of a JRE. An SDK is designed for development and contains the source code for the |
| Java library, easing debugging. Additional SDKs can be added by searching the hard drive for installed |
| SDKs. To do so, simply click the <strong>Search...</strong> button and specify a root folder for the search. |
| <br>If you work with code that does not yet use generics (as we do in this tutorial), we recommend |
| that you install a Java SDK 1.4 as well, but leave the most recent version checked as default. |
