How to Specify the Correct Relative Path for CSS Files in a Java Web Application?

Specifying the Relative Path to CSS Files

A Java web application often includes a CSS folder for styling purposes. To import a CSS file from this folder, you may face challenges if the path designation is incorrect.

Determining the Root Directory

CSS files should be located at the root of the project folder, which in your case contains:

• build
• css
• dist
• nbproject
• src
• web
• build.xml

Options for Specifying the Path

Two primary options exist for specifying the path to the CSS folder:

• Absolute Path: For example, . This path designates the root of the web application as the starting point.
• Relative Path: For example, . This path assumes the CSS folder is in the same directory as the HTML file (although this assumption should be verified).

Considerations

• Absolute Path: Use this path if the CSS file will always be referenced from the web application's root.
• Relative Path: Use this path if the CSS file is always in the same directory as the HTML file. It can be more efficient if you plan to remove the "/ServletApp/" portion of the URL.
• Filesystem Notations: Notations like ".." can be used to navigate up the directory structure, e.g., http://google.com/images/../images/../images/myImage.png.
