tried setting REPORT_TIME_ZONE four ways to no avail

[jesimone57]

 

In the following code, I have tried in vain to set the REPORT_TIME_ZONE according to what I have able to glean from reading all the discussion in these forums.  The result is the same, the JVM time zone is picked up instead of the timezone I am passing in "US/Pacific".

    public void writeCSVReport(Writer writer, ReportResultsDto resultDto)
            throws IOException, ClassNotFoundException, JRException {
           
        TimeZone timezone = resultDto.getTimezone();

        FastReportBuilder reportBuilder = new FastReportBuilder();
        reportBuilder.setUseFullPageWidth(false);
        reportBuilder.setPrintColumnNames(true);
        reportBuilder.setIgnorePagination(true);
        reportBuilder.setProperty(JRParameter.REPORT_TIME_ZONE, timezone.getID());

        int index = 0;
        for (ReportColumnMetadataDto metadataDto : resultDto.getMetadata()) {
            if (metadataDto.isDisplay()) {
                String columnLabel = metadataDto.getLabel();
                String columnClassName = metadataDto.getColumnClass();
                ClasscolumnClass = Class.forName(columnClassName);
                
                System.out.println("index="+index+"    label="+columnLabel+"     className="+columnClassName);
                
                if (java.util.Date.class.isAssignableFrom(columnClass)) {
                    reportBuilder.addColumn(columnLabel, String.valueOf(index),
                        columnClassName, metadataDto.getColumnSize(), false, "MM/dd/yyyy hh:mm:ss a zzz");
                } else {
                    reportBuilder.addColumn(columnLabel, String.valueOf(index),
                        columnClassName, metadataDto.getColumnSize());
                }
            }
            index++;  
        }

        DynamicReport dynamicReport = reportBuilder.build();
        dynamicReport.setProperty(JRParameter.REPORT_TIME_ZONE, timezone.getID());
        
        JRDataSource dataSource = new ReportResultsJRDataSource(resultDto);
        ((JRAbstractTextDataSource)dataSource).setTimeZone(timezone.getID());
        
        JasperPrint jasperPrint = DynamicJasperHelper.generateJasperPrint(dynamicReport, new ListLayoutManager(), dataSource);
        jasperPrint.setTimeZoneId(timezone.getID());
        
        System.out.println("n TIME ZONE SET TO >>>"+jasperPrint.getTimeZoneId()+"n");

        JRCsvExporter exporter = new JRCsvExporter();
        exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
        exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, writer);
        exporter.exportReport();

        writer.flush();
    }

 

 

Here is the output ...

 

index=0    label=My First Name     className=java.lang.String
index=1    label=My Last Name     className=java.lang.String
index=2    label=Email Address     className=java.lang.String
index=13    label=Registration Date     className=java.sql.Timestamp
index=14    label=Registration Status     className=java.lang.String
index=15    label=Payment Status     className=java.lang.String
index=16    label=Payment Type     className=java.lang.String

 TIME ZONE SET TO >>>US/Pacific

My First Name,My Last Name,Email Address,Registration Date,Registration Status,Payment Status,Payment Type

Any idea how I get jasper or dynamic jasper to respect the time zone?

 

Thanks in advance.

Here is the solution.   We needed to get the jasperPrint object to respect the timezone.  Unforunately, setting the timezone id into the jasper print object does not do anything.   I removed all the red code from the above post, which did not do anything either.

 

   public void writeCSVReport(Writer writer, ReportResultsDto resultDto)
            throws IOException, ClassNotFoundException, JRException {
           
        TimeZone timezone = resultDto.getTimezone();

        FastReportBuilder reportBuilder = new FastReportBuilder();
        reportBuilder.setUseFullPageWidth(false);
        reportBuilder.setPrintColumnNames(true);
        reportBuilder.setIgnorePagination(true);

        int index = 0;
        for (ReportColumnMetadataDto metadataDto : resultDto.getMetadata()) {
            if (metadataDto.isDisplay()) {
                String columnLabel = metadataDto.getLabel();
                String columnClassName = metadataDto.getColumnClass();
                ClasscolumnClass = Class.forName(columnClassName);
                
                System.out.println("index="+index+"    label="+columnLabel+"     className="+columnClassName);
                
                if (java.util.Date.class.isAssignableFrom(columnClass)) {
                    reportBuilder.addColumn(columnLabel, String.valueOf(index),
                        columnClassName, metadataDto.getColumnSize(), false, "MM/dd/yyyy hh:mm:ss a zzz");
                } else {
                    reportBuilder.addColumn(columnLabel, String.valueOf(index),
                        columnClassName, metadataDto.getColumnSize());
                }
            }
            index++;  
        }

        DynamicReport dynamicReport = reportBuilder.build();
        
        JRDataSource dataSource = new ReportResultsJRDataSource(resultDto);
  

            Map paramMap = new HashMap();
            paramMap.put(JRParameter.REPORT_TIME_ZONE, timezone);,>,>
            JasperPrint  jasperPrint = DynamicJasperHelper.generateJasperPrint(dynamicReport, new ListLayoutManager(),

                     dataSource, paramMap);
    
        System.out.println("n TIME ZONE SET TO >>>"+jasperPrint.getTimeZoneId()+"n");

        JRCsvExporter exporter = new JRCsvExporter();
        exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
        exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, writer);
        exporter.exportReport();

        writer.flush();
    }
