为什么JasperViewer（基于Swing的组件）没有在JavaFX项目中发布报告？ [英] Why JasperViewer (Swing based component) is not dispaying report at JavaFX project?

问题描述

我有两个运行JasperReports的项目。一个在JavaFX上运行，另一个在普通Java和主类上运行。现在，如果我运行普通Java项目jasperReport工作并显示（vai JasperViewer 类），但是使用JavaFX项目它可以工作但单击按钮后没有显示任何报告。

I have 2 projects which run JasperReports. One which runs on JavaFX and one with just plain Java and a main class. Now, if I ran the plain Java project jasperReport works and displays (vai JasperViewer class), but with the JavaFX project it works but no report displays after clicking the button.

为什么它适用于纯Java类但不适用于JavaFX？
$
如何才能使它在JavaFX中运行？

Why does it work for plain Java class but not for JavaFX?
What can I do to make it work in JavaFX?

除了javaFx和普通Java之外，其他所有内容都是相同的。我为此下载了以下jar文件：

Everything else is the same aside from them being javaFx and plain Java. I downloaded the following jar files for this:

• 动态Jasper 5.0.5。 jar


• jasperreports 5.6.0.jar


• commons-logging 1.2.jar


• commons beanutils 1.9。 2.jar



• commons digester 2.1.jar

• Dynamic Jasper 5.0.5. jar
• jasperreports 5.6.0.jar
• commons-logging 1.2.jar
• commons beanutils 1.9.2.jar

• commons digester 2.1.jar

commons collections 3.2.2.jar

推荐答案

好吧，这已经是一个过山车了，但我终于找到了我的解决方案，我希望它也会帮助别人。显然上述方法是正确的。一切都是正确的。唯一缺少的是 jasper-compliler-jdlt 5.5.23.jar 。所以，只要你拥有以上所有的罐子，它都应该有效。我还注意到，出于某种原因，如果你使用更高的DynamicJasper版本，如5.1.1，整个过程将无法正常工作。所以只是尝试保留以下jar文件（完整的jar文件列表可以在下面找到）以及上面的实现，你应该没问题。干杯和快乐的编码：）

All right, this has been one heck of a roller-coaster but I finally found my solution and I hope it will help others as well. So apparently the above approach is correct. Everything is right to the dot. The only thing missing is jasper-compliler-jdlt 5.5.23.jar. So as long as you have all the above jars it should work. I also noticed that for some reason if you use a higher DynamicJasper version like 5.1.1, the whole thing won't work. So just try to keep the following jar files(list of complete jar files can be found below) as well as the above implementation and you should be fine. Cheers and happy coding :)
