I downloaded the Date Formatter class which was part of the Adeptia Support Note titled "Date formatting for valid or invalid input dates". It was named dateformatter_670.class. I placed it in ServerKernel/customClasses as instructed. Then I created a custom Method with class name "DateFormatter" and method "processDateFormat" with 4 parameters. However I can't seem to get it to work. I've even tried renaming the class to DateFormatter.class, as well as placing it in the /Ext directory. Nothing seems to work.
Whether named dateformatter_670.class or DateFormatter.class, the Data Mapper debugger always gives me this message: javax.xml.transform.TransformerException: java.lang.ClassNotFoundException: DateFormatter
