Customizing the WebLogic Administration Console on CentOS

To customize the WebLogic Administration Console (the primary web-based management interface for WebLogic Server), you need to modify its themes, skins, or configuration files. Below are structured steps covering key customization aspects, organized by component and complexity.

1. Understand WebLogic UI Customization Components

The Administration Console’s appearance is controlled by three core elements:

• Skins: Define visual styles (colors, fonts, button backgrounds, spacing) via CSS and images.
• Themes: Apply skins to specific sections (e.g., Change Center, messages portlet) to limit visual changes to isolated components.
• Skeletons: JSPs that render HTML structure (e.g., portlet titles, layout boundaries) but are rarely modified for basic customization.

2. Locate Key Files for Customization

All UI resources are stored in the WebLogic installation directory under /framework/skins/. For a custom skin/theme named mycompany (replace with your identifier), the critical paths are:

• CSS Files: /framework/skins/mycompany/ (contains styles for buttons, forms, layouts, and portlets).
  Example files:
  • wls.css: General element styles (body, headers, tables).
  • button.css: Button appearances (active/inactive states, hover effects).
  • layout.css: Layout spacing and container borders.
• Images: /framework/skins/mycompany/images/ (button backgrounds, icons).
  Example: Button gradient images (e.g., button_bg.png) for customizing button visuals.

3. Modify CSS Files for Visual Changes

Edit CSS files in the mycompany skin directory to adjust colors, fonts, and spacing. Common modifications include:

• Button Styles: Change the background property in button.css to use a custom color or gradient.
  Example:

  .bea-portal-button {
    background: linear-gradient(to bottom, #4CAF50, #45a049); /* Green gradient */
    border-color: #3e8e41;
  }
  

• Form Elements: Adjust input field borders or font sizes in form.css.
  Example:

  input[type="text"], input[type="password"] {
    border: 1px solid #ccc;
    border-radius: 4px;
    padding: 5px;
    font-size: 14px;
  }
  

• Layout: Modify layout.css to change the console’s header/footer height or sidebar width.
  Example:

  .bea-portal-layout-header {
    height: 80px; /* Increase header height */
    background-color: #f8f9fa;
  }
  

After editing, save the files and clear the browser cache to see changes.

4. Customize Themes for Section-Specific Changes

If you want to limit visual changes to specific components (e.g., the Change Center portlet), modify the corresponding theme directory under /framework/skins/mycompany/. Themes reference skin files and add section-specific overrides:

• Example: Change Center Theme
  The Change Center portlet uses the wlschangemgmt theme. To customize its title bar background:
  1. Edit /framework/skins/mycompany/wlschangemgmt/theme.css.
  2. Add/modify the .wlschangemgmt-title-bar class:

     .wlschangemgmt-title-bar {
       background-color: #2196F3; /* Blue title bar */
       color: white;
     }
     

This change only affects the Change Center, leaving other components unchanged.

5. Use the Look & Feel Editor for Interactive Customization

For non-developers or iterative changes, use the Look & Feel Editor (accessible via the Administration Console):

1. Log in to the WebLogic Console.
2. Navigate to Deployments > Look & Feel Editor.
3. Select a component (e.g., “Buttons”) and modify its properties (e.g., color, size) using the drag-and-drop interface.
4. Save changes and preview them in real-time.
   This tool abstracts CSS editing and is ideal for simple visual tweaks.

6. Advanced: Modify Skeletons for Structural Changes

If you need to alter the HTML structure of components (e.g., add a custom logo to the header), edit the skeleton JSPs located in the WebLogic installation directory. However, this is advanced and not recommended for most users, as it can break the console if done incorrectly. Refer to Oracle’s official documentation for guidance.

7. Apply Changes and Restart

After making modifications:

1. Clear Browser Cache: To avoid seeing cached old styles, clear your browser’s cache or use incognito mode.
2. Restart WebLogic Server: Some changes may require a server restart to take effect. Use the following command on CentOS:

   sudo systemctl restart weblogic
   

   (Replace weblogic with your server instance name if different.)

Key Notes

• Backup Files: Always back up original CSS, image, and theme files before modifying them.
• Version Compatibility: Ensure your changes align with your WebLogic version (e.g., CSS classes differ between 12c and 14c).
• Oracle Documentation: For detailed instructions, refer to the WebLogic Portal Development Guide and Administration Console Look & Feel Editor Guide.

By following these steps, you can effectively customize the WebLogic Administration Console’s interface on CentOS to match your organization’s branding or user preferences. Start with simple CSS edits (e.g., button colors) and progress to themes or skeletons for more complex changes.
