Question

I’m using DynamicReports API for building reports.

I’m setting the Locale of the report and format the Date columns of the report, but the Dates are always formatted like 10/12/2009 10:54:44 AM no matter what the Locale is.

The code looks like:

rep.setTemplate(Templates.reportTemplate.setLocale(res.getLocale()));
...
if (rs.getString(i).contains("00:00:00"))
   rep.addColumn(col.column(title,  name,  type.dateType()));
else
   rep.addColumn(col.column(title,  name,  type.dateYearToSecondType()));

Is there a way to automatically format dates regarding to the Locale of the report or have I to use a custom ValueFormatter?

Answer 1

I also tryed the Parameter Map with no success

JasperReportBuilder rep = report()
   .setDataSource(query, conn.getConnection())
   .setParameter(JRParameter.REPORT_LOCALE, res.getLocale());
   .setTemplate(Templates.reportTemplate.setLocale(res.getLocale()));

There is no way to automatically format the dates.
The only way is to use patterns for the date column in respect to the locale.

TextColumnBuilder<Date> column = col.column(title,  name,  type.dateType());
if (res.getLocale().equals("EN") {
  column.setPattern("dd.MM.yyyy");
}
else if (res.getLocale().equals("US") {
  column.setPattern("MM/dd/yyyy");
}
else {
   ...
}
rep.addColumn(column);
