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,我收到一个对话框,提示我输入所有报告参数的值(其中两个是日期时间).无论以何种格式输入datetime参数,我总是得到以下异常:

我找不到什么问题.我为报告参数输入的默认值(以yyyy-MM-dd HH:mm:ss格式)是正常的,并且报告生成正确.但是,在启动调试器时,它们以不同的格式输入(MMMM d,yh:mm:ss).如果我这样离开他就会得到例外.如果我将它们更改为yyyy-MM-dd HH:mm:ss格式,我仍然会得到例外.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(以及删除日期时间报告参数)来绕过此问题.但在我这样做之后,出现了另一个例外:

你以前遇到过这个问题吗？你有什么建议我来解决它？

Answer 1

我按照建议做了:

• 更改为标准的"调试"透视图
• 在完整的"运行"菜单下,打开"调试配置"

我将"临时文件夹"条目更改为我的Windows用户帐户外的目录(即C驱动器下的内容,例如:C:\ Temp\Birt).我创建了指定的目录.

然后Eclipse调试工作.

Answer 2

我今天遇到了和你一样的 FileNotFoundException，我找到了解决方案。

异常的原因是文件路径是绝对路径，并尝试将临时文件保存在 / 没有写权限的地方。解决此问题的方法是简单地创建文件（在您的情况下为 /StandardOCE_PRS2_OperatorProductivity.rptdesign.html。我假设您使用的是 Linux）并使其可由运行 Eclipse 的用户写入。这将使您克服这个错误，但在那之后我又遇到了另一个错误，所以这对我来说不是一个好的解决方案。我认为这显然是 BIRT 插件中的一个错误，因为它应该使用 /tmp 来实现这一点。它甚至似乎在调试配置中进行了配置，但并未使用它。

然后我尝试找出如何更改调试配置。Eclipse 在“报告设计”透视图中隐藏了这一点，因此我有一段时间感到困惑，但如果您更改为 Java 透视图，您将看到“调试”按钮和完整的“运行”菜单。从按钮或菜单中打开“调试配置”，您将看到 BIRT 插件之前为您创建的配置。

如果我然后从那里运行它，它会按应有的方式使用 /tmp 目录并且调试工作。现在您还可以使用调试配置。可能有用！:-)
