  • If nothing is being loaded from the expected location of the class, take a look at Java CLASSPATH and make sure it’s part of it.
  • If some classes are being loaded from that location, it could be that another JAR file that contains that class is missing. Check Javadocs for the class in question.

Note: Once the problem is resolved, turn off the verbose logging as it can affect the application’s performance.
