Java report library for inclusion in a web page

I am working on a Grails application and I need to display some reports and allow users to export them to the most common formats (PDF, XML ...).

I don’t want to embed the SQL query in the report definition, the report logic is integrated into Grails services, and the report library I'm looking for should work on a data set (maybe a list of maps) without a real DataSource.

I used Jasper Reports and iReport for my tests, and they work great together with Grails for export functionality (PDF, XML, HTML). But it's hard for me to include them in my page template. I would like to have my header, footer, navigation menu and filter in the html report.

The only solution that occurred to me was to use an iframe, but I don't like it that much.

Can Jasper Report address my request? Do you know any other Java report library that allows me to include a report in my HTML object?

You can use g:include tag to enable the controller response:

 <g:include controller="myJasper" action="showReport" params="[foo: 'bar', baz: 42]" />

Using the Grails Jasper plugin , your controller will then contain this code:

 import org.codehaus.groovy.grails.plugins.jasper.JasperExportFormat; import org.codehaus.groovy.grails.plugins.jasper.JasperReportDef; class MyJasperController { def jasperService def showReport = { def reportDef = new JasperReportDef( name: 'your_report.jasper', parameters: params, fileFormat: JasperExportFormat.HTML_FORMAT) def report = jasperService.generateReport(reportDef) .toByteArray().toString("UTF-8") render report } }
