问题 I'm trying to use Jasper Reports to help with reporting in my application. I will have to display my reports in HTML (JSP) and would also need to be able to export the reports to PDF from within my web page. Most of my reports require multiple parameters, and I can't figure out how to pass them from my Servlet (if I have to pass them there) to the report. P.S: I'm not using frameworks of any sort, it would be great if you could suggest a framework free implementation. 回答1: //Preparing data -

问题 I am using iReport to build jaspersoft reports and I am using Fishbowl as my DBMS. I built my tables and in iReport is shows that my tables are relational but for some reason it is throwing me errors and will not run. It should be very simple. I am taking in a zipcode, date range or State Name and outputing the productName, total quantity fulfilled, zip and state abbreviation. When I do upload the report to Fishbowl it runs but eventually crashes with an error saying it's out of memory. I do

问题 Problem Constraints Size of the data set, but not the data itself, is known. Data set grows by one data point at a time. Trend line is graphed one data point at a time (using a spline/Bezier curve). Graphs The collage below shows data sets with reasonably accurate trend lines: The graphs are: Upper-left. By hour, with ~24 data points. Upper-right. By day for one year, with ~365 data points. Lower-left. By week for one year, with ~52 data points. Lower-right. By month for one year, with ~12

问题 I have a report created in jasperreports 2.0.4 using iReport. I have two subreports. These two subreports share the same jrxml. I'm passing the jrxml as the subreport's report expression in a parameter.

问题 Using iReport 2.0.2. I have a barcode font that I would like to use, but the first problem is that it isn't included in iReport. I tried to work around the problem by using the barcode font as a regular font and it works fine, but the problem appears when I send the PDF to a component (pdfBox) that sends the PDF directly to printer. The component can't recognize the font (it's long story and not relevant) even though it's embeded and reverts the barcode to Arial. What I would need is to

问题 I am using iReport's to format the results of a query. The results are currently something like this: Id firstname surname - id firstname surname 1 dan n 45 dan n 1 dan n 46 dan n 3 john d 102 john d 4 john f 109 john f 4 john f 110 john f I would like them to look more like this: Id firstname surname - id firstname surname 1 dan n 45 dan n 46 dan n 3 john d 102 john d 4 john f 109 john f 110 john f I know that iReport has the 'print when Repeated Values feature, but if i use this I get the

问题 Is it possible to execute "insert query" in IReports/jasper reports during report generation? 回答1: Yes, the idea you need is parameters using this syntax: $P!{PARAM_NAME} . So your entire SQL query (or other type of query) could be simply $P!{SQL} . Then you pass in exactly the dynamic SQL that you need. UPDATE: After reading Sharad's comment, I realized that my answer above is not good. What I wrote is true... but it fails to address the core question. No, your report cannot really execute

问题 I need help making only one (complete) Pie Chart show up when using GROUP BY in my query ( SQL ) using iReport 4.6.0. I need to create a report using iReport (4.6.0; I am using the standalone version, not the NetBeans Plug-in) using data pulled from an SQL database.

问题 I have no idea if this is possible or not but I'm trying figure out if it is possible to use iReport Designer to create reports where the user viewing the report is able to control the grouping. For example I would like the user to be able to re-order the grouping and also change to which degree the report is grouped (only on one field or on multiple ones). I don't mean SQL grouping btw, I mean for example grouping by Account and then Agent: | Account | Agent | Invoice | Total | +----------+-
