eclipse - 尝试调试 birt 报告时出现异常

Question

我想调试图表的 afterDataSetFilled 方法。当我开始调试时，出现一个对话框，提示我输入所有报告参数的值(其中两个是日期时间)。无论我以哪种格式输入日期时间参数，我总是会遇到以下异常:

SEVERE: Engine exception

我找不到问题所在。我为报告参数输入的默认值(以 yyyy-MM-dd HH:mm:ss 格式)是可以的，并且可以正确生成报告。但是，启动调试器时，它们会以不同的格式输入(MMMM d, y h:mm:ss)。如果我就这样离开他们，我就会得到异常(exception)。如果我将它们更改为 yyyy-MM-dd HH:mm:ss 格式，我仍然会遇到异常。这是一个已知的 BIRT 问题，还是我做错了什么？

我能够通过在 SQL 查询中对这些值进行硬编码(并删除日期时间报告参数)来绕过此问题。但在我这样做之后，又出现了一个异常:

您以前遇到过这个问题吗？你建议我做什么来解决它？

Answer 1

我按照建议做了:

• 更改为标准“调试”视角
• 在完整的“运行”菜单下，打开“调试配置”

我将“临时文件夹”条目更改为 Windows 用户帐户之外的目录(即 C 驱动器下的某个目录，例如:C:\Temp\Birt)。我创建了指定的目录。

然后 Eclipse 调试就成功了。
