Hi, Is there any way to dynamically increase the size of a image in jasper report? I am creating a chart using JFreechart and putting it in the report as a image. The problem is the chart is created dynamically, so i don't know the size of it. For a chart with horizontal orientation, the bars are crushed together and also when the legend becomes big, it occupies all the space and the chart is not visible at all. Can anybody plz help me. Thanks

I tried that.It did not help

hi I am trying to export my report in XL format.The exported XL does not have grids.Can anybody help me. The grids appear in open office but not in Microsoft Excel

Is it possible to export images to an Excel file? We are working with JFreeChart and couldn't find any documentation saying if it's possible or not to do this.

Thank you very much. It worked..

Thanks for your help. now my problem is 08:36:03,015 INFO [sTDOUT] Caused by: net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. The method loadImage(byte[]) in the type JRImageLoader is not applicable for the arguments (Byte) value = (java.awt.Image)(net.sf.jasperreports.engine.util.JRImageLoader.loadImage(((java.lang.Byte)field_company__companyLargeLogo.getValue()))); <-------> Bcoz the data type i gave for the field is java.lang.Byte so i tried byteValue() but that also did not help 08:40:22,827 INFO [sTDOUT] Caused by: net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1.

I tried that it says 12:36:31,562 INFO [sTDOUT] Caused by: net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. JRImageLoader cannot be resolved value = (java.awt.Image)(JRImageLoader.loadImage(((java.lang.Byte)field_companyLargeLogo.getValue()))); <-----------> Can u plz help me

Hi I have many images stored in my database as BLOB.when i get the data they are as bytes. so i have field image which of type byte. how do i print the image on the report. how do i convert it into inputstream or any other format. Is there any way to do it in ireport or can it be done only in code like this: InputStream in = new ByteArrayInputStream(byte[]); Thanks

Thank you very much....was caught up with this problem for so long..

hi I am using a datasource to fill my report..How can i fill my sub report which uses the same datasource.. Actually it is a list of bean values and i loaded it into a datasource and i am filling my report. For example: List of bean Order for main report.. The main report takes values like Order.getOrderName(),Order.getOrderNumber(),Order.getOrderDate() etc... The sub report takes values present in Order.getOrderServices..which is again a list.. List Services = (List)Order.getOrderServices(); for(int j=0;j<Services.size();j++) { OrderService orderService= (OrderService)Services.get(j); data[j][1]=orderService.getService().getServiceName(); data[j][2]=orderService.getOrderServicePrice(); } This is not my exact code..just to show what values i want in my sub report.. How do i do this.. If iam not clear..i can provide more details.. Thanks Post edited by: divsen, at: 2006/08/29 17:57

It is not showing any errors..Is there any settings i must make..or nay jar files that must be added..i downlaoded the ireports windows installer and installed it on my system.. one more question..when it try to use a report with a chart in a web page..it says some org package class is not found..which is the jar i must include for that..i have included the jasperreports-1.2.5.jar file in my lib folder.. Thanks
