java - Jasper Reports + WebSphere 7，ExceptionInInitializerError 异常

Question

调用 JasperFillManager.fillReport() 时，我们遇到以下异常。令人困惑的是，它发生在我们的“生产”环境中，但在我们的测试环境中运行良好。

显然这个问题发生在静态属性初始化期间，我们认为这可能与 Jasper 所做的多线程处理(ThreadLocal-stuff)有关。

我们已经按照一些建议的指示尝试了 java.awt.headless=true J​​VM 设置，但没有任何变化。我们确实需要故障排除的建议，或者关于在一种环境中而不是在另一种环境中可能导致这种情况的原因的线索。据我们所知，它们是相同的，但显然有些东西是不同的，我们没有办法检查。所以问题确实是...我们如何解决这样的问题？

Jasper Reports 4.7(3.7 也出现)

Java 1.6、Flex(服务器上的 GraniteDS)/Spring/Hibernate
(我们没有使用 EJB，我们通过一个简单的 war 文件进行部署)

Answer 1

要解决该问题，您需要获取静态初始值设定项引发的原始异常。通常，第一次尝试加载包含静态初始化程序的类时，该异常会链接到 ExceptionInInitializerError。

因此你需要做两件事:

1. 确保您能够获取整个堆栈跟踪。您发布的堆栈跟踪似乎被截断(请参阅 ***BUFFER OVERFLOW*** 标记)。
2. 获取第一次尝试初始化类时引发的异常的堆栈跟踪。如有必要，请重新启动应用程序或服务器。
