JasperReports in .Net over IKVM

我愿意在.Net中使用JasperReports。JasperReports in .Net over IKVM

我使用IKVM.net为此构建所需的DLL，并翻译了一个示例应用程序。

但我得到在C＃中NotImplementedExeption（在Java中的等价代码工作完全）

JasperPrint print = JasperFillManager.fillReport(jasperFileDialog.FileName, null, new JREmptyDataSource());

的方法或操作未实现。

见下

注意堆栈跟踪： IKVM版本：0.40.0.1 http://sourceforge.net/projects/ikvm/files/ikvm/0.40.0.1/ikvmbin-0.40.0.1.zip/download

下载JasperReports 3.7.0 project，分组在\ lib中所有的罐子和一个文件夹中的JasperReports-3.7.0.jar
使用过的jar2ikvmc生成ikmvc脚本http://code.google.com/p/jar2ikvmc/downloads/list
运行脚本，我得到了很多ClassNotDefound的警告
引用在C＃应用程序的所有DLL，除了所有IKVM dll文件除了IKVM-native.dll

异常堆栈跟踪

尝试使用反射器检查生成的dll中的方法定义/声明 – A9S6

您的堆栈跟踪不会显示NotImplementedExeption来自何处。没有这些信息就无法回答。 – Horcrux7

你有没有得到这个工作？ – FlappySocks

当Jasper Reports jar依赖于另一个jar时，通常没有发现异常。例如，如果jasperreport.jar使用另一个类似log4net.jar的jar，则首先需要将相关jar转换为dll。然后在转换jasperreport期间使用转换后的dll进行链接。将Apache POI转换为dll时遇到同样的问题。
