Resolving java.lang.ClassNotFoundException Despite Using CLASSPATH Environment Variable
While attempting to connect to a MySQL database using Java in Windows 7, setting the CLASSPATH environment variable to include the path to the JDBC driver jar file doesn't seem to resolve the java.lang.ClassNotFoundException: com.mysql.jdbc.Driver error. What could be causing this issue?
Answer:
The CLASSPATH environment variable is only utilized by the java.exe command and is not considered when using IDEs like Eclipse. It's generally regarded as a poor practice due to portability concerns.
Instead, use the "Build Path" setting within the IDE. This allows you to specify the compile-time and runtime classpath for your project, ensuring that necessary libraries like the JDBC driver jar are accessible.
Additional Considerations:
- Refer to the linked resource for more details on configuring the classpath when working with WAR projects in Java.
- Avoid relying on the CLASSPATH environment variable as it can lead to confusion and portability issues.
