Possible solutions

For a successful import, the path to the Java class should be specified either in the CLASSPATH environment variable or in the --java-option passed to qfgl, unless it is a standard Java class - https://querix.com/go/lycia/index.htm#09_auxiliary/java/classes_objects/java_import_java_classes.htm
Please ensure that you have one-to-one mapping between the package name and the file system directory structure:

3. In case your Java class refers to another class, please make sure all dependencies are added to your CLASSPATH environment variable.
