| </p> |
| <ol> |
| <li> |
| Open the |
| <a class="command-link" href='javascript:executeCommand("org.eclipse.ui.window.preferences(preferencePageId=org.eclipse.jdt.debug.ui.preferences.VMPreferencePage)")'> |

| <strong>Java > Installed JREs</strong></a> preference page. |
| </li> |
| <li> |
| Select the JRE definition that you want to edit and click <strong>Edit...</strong>. The Edit JRE page opens. |
| </li> |
| <li> |
| In the <strong>JRE name</strong> field, edit the name for the JRE definition. All JREs of the same type must have a unique name. |
| </li> |
| <li> |
| In the <strong>JRE home directory</strong> field, edit or click <strong>Browse...</strong> to select the path to the root |
| directory of the JRE installation (usually the directory containing the <em>bin</em> and <em>lib</em> directories for the JRE). This location is checked |
| automatically to make sure it is a valid path. |
| </li> |
| <li> |
| In the <strong>Javadoc URL</strong> field, edit or click <strong>Browse...</strong> to select the URL location. The location is |
| used by the Javadoc export wizard as a default value and by the 'Open External Javadoc' action. |
| </li> |
| <li> |
| If you want to use the default libraries and source files for this JRE, select the <strong>Use default system libraries</strong> checkbox. |
| Otherwise, clear it and customize as desired. Source can be attached for the referenced jars as well. |
| </li> |
| <li> |
| Click <strong>OK</strong> when you are done. |
