使用birt引擎生成報告時的FontHandler異常

在birt報告生成期間，我正在低於excpetion。下面給出堆棧跟蹤代碼。使用birt引擎生成報告時的FontHandler異常

我需要在我的應用程序中添加任何其他字體相關的文件嗎？有沒有人有這方面的想法。

當我把選項渲染爲'HTML'時，它工作正常。只有當我把渲染選項設置爲'pdf'時纔會拋出異常。

我的堆棧跟蹤是：

嘗試之一：

添加您的字體目錄到CLASSPATH（或複製/符號鏈接報告字體，以在CLASSPATH任何目錄）

註冊的字體目錄用下面的代碼：

import java.security.AccessController; 
import java.security.PrivilegedAction;  
import com.lowagie.text.FontFactory; 

... 

AccessController.doPrivileged(new PrivilegedAction<Object>() { 
     public Object run() { 
       FontFactory.registerDirectory(yourFontsDirectory); 
       return null; 
     } 
});

字體目錄應包含TTF字體使用通過你的報告設計。

我認爲你需要設置的區域設置爲task.setLocale(new Locale("en", "US"));
