我使用的是 Windows 7 专业版。 我尝试更改默认浏览器或将此行输入到 eclipse.ini 文件但没有帮助。

希望得到您的帮助..

Answer 1

切换到 Debug 透视图，您可以访问完整的“运行”菜单。打开“调试配置...”，这应该可以让您访问“报告”下的项目，这是您调试配置。在此项目中，将“临时文件夹”位置更改为您信任的位置。应该可以解决的。

Answer 2

从你的错误

引起：java.io.FileNotFoundException： \reportForGenerateFromEngine.rptdesign.html（访问被拒绝）"

这是一个文件系统问题。如果您在 BIRT Designer 中进行预览，请验证您的保存位置是否可写，并可选择尝试以管理员身份运行 BIRT Designer（只是为了检查）。否则，请检查您是否有权使用您用于生成此报告的任何方法进行读写。
