java - 使用 SP24 for Eclipse 运行 Crystal Reports 时出现 NullPointerException

Question

我们正在尝试将 Crystal Report for Eclipse 升级到 SP24，但发现我们的一些报告在生成报告时失败并出现 NullPointerException。我在下面包含了堆栈跟踪 - 请问有人知道什么地方可能有问题或有任何解决方法吗？

Answer 1

以防其他人在这里遇到同样的问题。

问题是:较新的 JDK 版本没有附带 Crystal Report 引擎期望的 lib/fonts 文件夹。

一个有点不令人满意但可行的解决方案是:

1. 创建字体文件夹 -> %JAVA_HOME%/lib/fonts
2. 将字体从“Windows\Fonts”复制到 %JAVA_HOME%/lib/fonts。

问题应该解决了。
