在开发模式下生成JasperReport时出错 [英] Error generating JasperReport in Development mode

问题描述

我在启动时在程序中初始化报告时遇到问题。
前一段时间，它可以正常工作。但是当我将JDK 1.7更新17解除对JDK 1.7更新21以及全新安装Netbeans时，存在异常：（

i have problem when initialize report in program at startup. Sometime ago, it works correctly. But when i unistall JDK 1.7 update 17 to JDK 1.7 update 21, and fresh install Netbeans , the Exception exist :(

这是错误消息：

这是我的初始化报告的代码。

And this is my code to initialize report.

public void initReport() {
        try {
            param.put("noMr", "0000");
            param.put("visitCode", "V-199208300000");
            param.put("templateLoco", iReportDir);
            param.put("tools", "Tools");
            param.put("medicine", "Medicine");
            param.put("result", "Data hasil disini");
            param.put("conclusion", "Data kesimpulan disini");
            param.put("suggestion", "Suggestion");
            param.put("SUBREPORT_DIR",iReportDir);

            String imageLoco = iReportDir +"image-sample.jpg";
            for (int i = 0; i < 20; i++) {        
                FileInputStream image = new FileInputStream(imageLoco);
                param.put("imgResult"+(i+1), image);
            }

            param.put("emptyImg", iReportDir+"logo.jpg");

            setTemplate("data/reports/templates/template_1.jasper");

            jasperPrint = JasperFillManager.fillReport(getTemplate(), param, DatabaseUtility.getConnection());
        } catch (JRException ex) {
            System.out.println(ex.getMessage());
        } catch (IOException ioe) {
            System.out.println(ioe.getMessage());
        }
    }

但是，当我构建时，和。 Jar，错误消失了。

But, the And when I build to. Jar, the error disappears.

请帮助，谢谢之前：）

推荐答案

您使用的是Calibri字体吗？我发现这是一个jdk 1.7.0_21错误，似乎特定于Calibri。
尝试将字体切换为Arial，错误应该消失。

Are you using the Calibri font? I've found that this is a jdk 1.7.0_21 bug and seems to be specific to Calibri. Try switching the font to Arial and the error should go away.

如果要修改大量报告和子报告，这可能会有所帮助：

If you have lots of reports and subreports to modify, this might help:

find . *.jrxml -type f -print0 |xargs -0 grep -lZ "Calibri" |xargs -0 sed -i 's/Calibri/Arial/g' 

我有一个应用程序也调用相同的JasperFillManager方法，我可以确认在jdk 1.7_0_21中看到相同的堆栈跟踪。如果我将jdk更改为1.7_0_17或1.7_0_07，则不会发生错误。
该类位于rt.jar中，据我所知，源代码不可用。但1.7基于openjdk，可以在 jdk7src 找到非常相似的来源。

I have an application that also calls into the same JasperFillManager method and I can confirm that I see the same stacktrace in jdk 1.7_0_21. If I changing the jdk to 1.7_0_17 or 1.7_0_07 the error does not occur. The class is in the rt.jar and as far as I know, source is not available. But 1.7 was based on openjdk and very similar source can be found at jdk7src.

调试应用程序，我可以看到createCharinfo获取一个StandardGlyphVector对象并查询它的字形数，返回0. StandardGlyphVector.getGlyphCharIndices（0,0，null）然后返回一个非null但是空数组。 sun.font.ExtendedTextSourceLabel代码不检查null或空数组返回情况，并尝试访问正确抛出AIOOBE的数组。

Debugging the application, I can see that createCharinfo gets a StandardGlyphVector object and queries it for the number of glyphs, which returns 0. StandardGlyphVector.getGlyphCharIndices(0,0,null) then returns a non-null but empty array. The sun.font.ExtendedTextSourceLabel code doesn't check for null or empty array return cases and tries to access into the array which correctly throws the AIOOBE.

似乎有相关错误报告此处。
