是的，Jasper Reports带有一个可用的（虽然很简单）报表查看器：

Yes you can, Jasper Reports come with a usable (albeit simple) report viewer:

...
           JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
           JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport...);
           JasperViewer.viewReport(jasperPrint);
...

最后一行是显示查看器的内容。不过，我不确定你是否可以将可用的输出格式限制为PDF。

The last line is what displays the viewer. I'm not sure if you can restrict the available output formats to PDF, though.
