Not sure if you are exporting report locally or on server but both are java applications. That also means that if process is done and memory is needed Garbage collector may clear up heap and make space for further operation but wont release memory back to operating system - he does not have reason to do so.... You can adjust Java settings so it consumes less memory and is limited to certain amount of memory in total (xmx, xms and other settings). So process will still hold onto its memory which is allocated to it even though he is inactive. There are certain ways how to configure GC to do so but it needs to be set to do so and it does not always work...see http://stackoverflow.com/questions/11919400/release-java-memory-for-os-at-runtime

Using Jasper Server 5.2 comunity edition and its stable enough for everything;) You can find it here: http://community.jaspersoft.com/project/jasperreports-server/releases

You can place your header to a Band and then you can use this: <printWhenExpression><![CDATA[$V{PAGE_NUMBER}==1]]></printWhenExpression> for this Band, this way it will only print on first page. PAGE_NUMBER is always accessible parameter.

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?

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.

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.

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
