How to determine the next Sunday from today in JasperReports?

Issue Description

Relative Dates feature in JasperReports Server is great for setting/getting date values relative to the current day, but they don't have a concept of the actual day of week. If you need to determine the next Sunday from today, for example, you can try using java.time.temporal.TemporalAdjuster in an expression.

Resolution

Try an expression with syntax similar to the following which instantiates a java.time.LocalDate object:

LocalDate.parse($F{InputParam_Date}, DateTimeFormatter.ISO_OFFSET_DATE_TIME).with(TemporalAdjusters.nextOrSame(DayOfWeek.SUNDAY))
