parameter REPORT_TIME_ZONE set by valid java.util.Timezone throws exception

0

Hello,

I am using JasperServer comunity edition 5.0.0 and I am doing webservice call using jasperserver-ireport-plugin-4.2.0.jar in Java . All functionality and parameters works...except for JRParameter.REPORT_TIME_ZONE. My code structure looks like this:       

parameters.put(JRParameter.REPORT_TIME_ZONE, TimeZone.getDefault()); //yes it is java.util.TimeZone and yes I tested multiple timezones

parameters.put(JRParameter.REPORT_LOCALE, reportLocale); //here I set locale and it works when I comment out adding REPORT_TIME_ZONE parameter

Map runReport = myJasperWebService.runReport(rd.getUriString(), parameters, serverParameters); //here I run report

 

And I am getting

 

java.lang.Exception: 1 - java.lang.String cannot be cast to java.util.TimeZone
    at com.jaspersoft.jasperserver.irplugin.wsclient.WSClient.runReport(WSClient.java:382)
    at main.MyJIClient.runReport(MyJIClient.java:96)
    at main.Run.main(Run.java:64)

runReport method has only this...

    ResourceDescriptor rd = new ResourceDescriptor();
    rd.setWsType(ResourceDescriptor.TYPE_REPORTUNIT);
    rd.setUriString(reportUri);
    return server.getWSClient().runReport(rd, parameters, serverParameters);

 

Am I using it wrong, which I dont think so because every other parameter including Locale settings works nice and reports are created or is there possibly problem in implementation of ireport-plugin or JasperServer implementation?

 

Thanks for any advice or hint

I am not sure if this answer helps but just adding my points(hope it help)

In your iReport , go to Tools-> Options -> Compilation and execution  -> Look for Reprot Time Zone,

may be it is creating conflict with yours,

do you need to override it or something

Hi, thansks a lot for answer. Report has set Default timezone however when run on JAsperServer I need to pass him timezoen as parameter, which should be done by setting parameter REPORT_TIME_ZONE because I need to specify in which timezone dates and time should be shown in generated report.

However when I pass this parameter I get

java.lang.Exception: 1 - java.lang.String cannot be cast to java.util.TimeZone
at com.jaspersoft.jasperserver.irplugin.wsclient.WSClient.runReport(WSClient.java:382)
at main.MyJIClient.runReport(MyJIClient.java:96)
at main.Run.main(Run.java:64)

I need to override the timezone but so far withotu success.

You are trying to set a string value to TimeZone variable amma.

If you want a TimeZone variable, check for TimeZone API and see how to pass string value to it.

hope that helps.

Hi, thanks again for answer however as I wrote in question...

parameters.put(JRParameter.REPORT_TIME_ZONE, TimeZone.getDefault()); //yes it is java.util.TimeZone and yes I tested multiple timezones

I am passing valid java.util.Timezone not any string and still I am getting this exception...that is the problem..by all manuals, tutorials and how-tos I am doing it in correct way and it is not working.

Ok made some more research, still same problem, but looks like server doesn't recognize sun.util.calendar.ZoneInfo as as java.util.TimeZone.

 

//adding timezone as parameter

parameters.put(JRParameter.REPORT_TIME_ZONE, TimeZone.getDefault() );

 

in debug mode in eclipse I see that parameter is defined as REPORT_TIME_ZONE=sun.util.calendar.ZoneInfo[id="Europe/Berlin",offset=3600000,dstSavings=3600000,useDaylight=true,transitions=143,lastRule=java.util.SimpleTimeZone[id=Europe/Berlin,offset=3600000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=2,startMonth=2,startDay=-1,startDayOfWeek=1,startTime=3600000,startTimeMode=2,endMode=2,endMonth=9,endDay=-1,endDayOfWeek=1,endTime=3600000,endTimeMode=2]]

But this is default timezone definition in Java. Is there any workaround or anyone has idea how to solve this problem?
