Dealing with "NoClassDefFoundError: org/openqa/selenium/WebDriver" When Working with Selenium

Despite updating your Maven dependency and importing the correct Selenium classes, you may encounter the "NoClassDefFoundError: org/openqa/selenium/WebDriver" error when running your Java application. This error typically indicates that the Selenium library was not properly loaded or included in your project's classpath.

Troubleshooting Steps:

Confirm the Dependency: Ensure that your pom.xml file contains the most recent Selenium dependency, as specified in the provided code snippet.
Check the Repository: Navigate to your local Maven repository (~/.m2/repository) and verify that the seleniumhq folder exists instead of the openqa folder. It's possible that your IDE may not be referencing the correct Maven repository.
Import from Seleniumhq: Ignore the org.openqa... import path suggested in the Selenium documentation. Instead, import from the seleniumhq package, which is where the actual Selenium classes reside.

Specific Eclipse Troubleshooting:

Update the Build Path: In Eclipse, access the Project properties and go to Java Build Path. Remove any Selenium jars from the Modulepath and add them to the Classpath instead.
Clean and Run: Perform a Clean from the Project menu at the top of Eclipse to clear any previous build artifacts. Then, execute a Run to attempt to resolve the error.

By following these steps, you can ensure that the Selenium library is properly installed, referenced in your project's build path, and can be used without encountering the "NoClassDefFoundError: org/openqa/selenium/WebDriver" error.

Top 5 Java Features: Examples and ExplanationsMay 12, 2025 am 12:09 AM

The five major features of Java are polymorphism, Lambda expressions, StreamsAPI, generics and exception handling. 1. Polymorphism allows objects of different classes to be used as objects of common base classes. 2. Lambda expressions make the code more concise, especially suitable for handling collections and streams. 3.StreamsAPI efficiently processes large data sets and supports declarative operations. 4. Generics provide type safety and reusability, and type errors are caught during compilation. 5. Exception handling helps handle errors elegantly and write reliable software.
