Fonts 贾斯珀报告+；PDF生成问题

我正在展示一份jasper报告。现在我有了一个图标，可以得到相同的PDF格式的报告

现在，当我使用Tomcat在操作系统中部署代码时，它工作得很好，但我现在面临的问题是，我们创建了一个没有UI的Ubuntu虚拟机映像

当我试图下载PDF格式的报告时，我得到了一个错误，在网上和这里进行了广泛的搜索后，我发现字体丢失了，因此出现了这个问题

现在，我已经硬编码了字体的路径，并将true type字体也放在报表文件夹的同一路径中。但我还是犯了个错误

下面是我放在JRXML文件中的代码

<font size="20" isBold="false" fontName="Verdana" pdfFontName="/var/lib/tomcat6/webapps/WallCloud/jsp/dashboard/reports/Helvetica.ttf" isBold="false" isPdfEmbedded ="true"/>

这是在线上的

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, conn);

这是我的pdf生成代码

        conn = dbConn.getSimpleConnection();
        String path = getServletContext().getRealPath("/")+"/jsp/reports/Report.jrxml";


      JasperDesign jasperD = JRXmlLoader.load(path);
            JasperReport jasperReport = JasperCompileManager.compileReport(jasperD);
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            response.setContentType("application/pdf");
            response.setHeader("Content-Disposition", "inline; filename=\"Report.pdf\"");   
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, conn);
                    net.sf.jasperreports.engine.JasperExportManager.exportReportToPdfStream(jasperPrint, baos);

                response.setContentLength(baos.size());
            ServletOutputStream out1 = response.getOutputStream();
            baos.writeTo(out1);

            out1.flush();
            conn.close();
        } catch (Exception se) {

        }

如何解决此问题？

我找到了此问题的解决方案。我们需要：

编辑/etc/apt/sources/list

添加以下行

德布哈代多重宇宙

deb-src-hardy多重宇宙

黛布·哈代更新多元宇宙

deb src hardy更新多元宇宙

sudoapt获得更新

sudo apt get安装msttcorefonts

这就解决了问题，并且PDF也会生成。

在您的目标应用程序中部署报表模板时，将所需字体与报表模板一起提供

问候,
