Hi, Am developing a chart using JFreeCharts and passing this chart as image to the jasper report. Am not getting the image in the pdf. Am getting empty pdf but the size of pdf is 892 bytes. Am not understanding why this is happening. Suggest me a way how to pass the image(chart sent as image as parameter to the jasper report) . The thing here is i should not save image some where in the disk and pass the relative path of the image to the report. So the only option i have is to send the image content directly to the report as a parameter. Am sending the image to the report as parameter taking the type as java.awt.Image only. Even though am not getting image in pdf. So please help me Thanks in advance

Hi rajendra, The request flow is like this. UI--->ReportServlet------->Service Class----------->Generate report. This flow is common for all the reports. From UI request is going to ReportServlet where am deciding which jrxml to load and set all required things to send them to database. In Service class am setting all the report column header names as parameters which am going to retrieve in jasper. And the GenerateReport class will set required properties like IS_IGNORE_CELL_BORDER, IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, IS_ONE_PAGE_PER_SHEET etc. This Generate report class is common for all the reports. So i cant add the code here to set sheet name. The only option i have is to send the sheet name as parameter(like column headers) and make use of it in jasper by using "net.sf.jasperreports.export.xls.sheet.names.all" property. But problem am facing here is "How can i set a parameter value(sheet name which is sent dynamically from java side to jasper) to a property like net.sf.jasperreports.export.xls.sheet.names.all". As per my requirement i dont have an option to set the sheet name in the java side.

Ya rajendra i can go with that code. As i told my java code for generating reports is common for all the reports. The code which u gave will affect the other reprots if i chage that common java file(code used to generate report) . Suggest me a way where i can pass report name as parameter from a java class(called service class in my report) without using jasper properties in java. So that i can retrieve that report name in jasper and make use of it.

Hi I will explain u my probelm clearly now My project is having many reports. In those,two reports are using same jrxml. And i wrote separate java file which contains the logic for generating the reports. So i cant use JRProperties class here. Am passing all the column headers and parameters to the report through a separate service(each report has separate service class)class. So now suggest me the ways how i can pass the report name from this service class and use it in jasper. I think u got my problem now Please help in this regard

Hi, Am generating the report using java code. From java code am passing xls report name as parameter. I want to make use of this parameter value to set the name of report.

Thanks in Advance
