The document provides a sample java class that is to be used with the schema specific to the example given in the document. However the sample code does not have any comments nor does the document provide any further instructions or links to additional information, that the user can use to modify the code for their own specific schema. Any errors in the code are only revealed when binary data is read/written using PXF making debugging difficult/tedious for someone not familiar with java.
