I'm trying to display a column of money, which is currently a numeric data type (Postgres). The following syntax examples work pefectly in DBeaver, but produce errors in Jasper Studio. Does anyone have suggestions to display money ($79,967,345.23 for example)? I've tried dropping the postgresql-42.2.20.jre7.jar file (includes PG Money class) in to various folders containing other Jasper-related jar files, but continue to receive the error. sum(d.revenue)::money --> Error: net.sf.jasperreports.engine.JRException: Unable to get value for result set field "sum" of class org.postgresql.util.PGmoney cast(sum(d.revenue) as MONEY) --> Error: java.lang.ClassNotFoundException: org.postgresql.util.PGmoney cannot be found by net.sf.jasperreports_6.16.0.final --- net.sf.jasperreports.engine.design.JRDesignField@694ba313 If I use just "sum(d.revenue)", the correct information is displayed, but looks like a meaningless (hard-to-read) number.
