问题 Is there a way to export a Jasper report in PDF where designated fields can be left editable? I'm using iReport to design the report templates. 回答1: It's not possible today. It's an unusual requirement, but it's not unreasonable. It's really not an iReport limitation but rather a JasperReports limitation. If anyone coming to this post in the future would like to have this feature, the best thing to do would be to log it in the Jaspersoft bug tracker. 回答2: Two facts: iText can do it. http:/

问题 Using iReport v4.0.1 with Jasperserver v4.1.0 I'm trying to find a syntax for linking subreports to the main report that lets me test it in iReport then deploy to the server through the repository browser. The default syntax for sub-reports in iReport for the subreport expression is something like $P{SUBREPORT_DIR} + "mySubReport.jasper" When you deploy this from iReport it's smart enough to pick this up and suggest changing it to "repo:mySubReport.jrxml" and to then deploy all subreports to

问题 I have created one .jasper file for my project. I am getting an output in JasperViewer window, but instead of that I want to see it in HTML output form. How can I do that? 回答1: Jasper report project comes with a sample code to export reports to HTML. It's not only a single HTML file, but at least it requires a 1x1 transparent gif used for decorating. It's not a good idea to export reports to HTML files because of portability and printing issues. You can however show HTML reports inside your

问题 I have developed a web application that uses JasperReports. I noticed that the reports are printing server-side. How do you make the reports print client-side (from the web browser)? Any insights will be helpful. 回答1: Presuming you have a Servlets-based architecture: Get a handle on the HttpServletResponse instance with HttpServletResponse response = this.getThreadLocalResponse(); (for instance). Set the various headers to indicate a file attachment. HttpServletResponse response =

问题 I have some Jasper reports which are displayed in HTML format. I would like the width of the columns in the HTML tables to automatically resize to fit the content of the widest cell (in that column), such that all the data is displayed.
