前段时间做birt集成开发，遇到一个问题，报表始终不能正确生成

日志如下：

检查路径中Tidy.jar是存在的，初步判断是权限的问题。

在多次尝试后发现Tidy.jar 存在于2个地方

1. ReportEngine/configuration/org.eclipse.osgi/bundles/51/1/.cp/lib (黄色部分可能会有变化)

2. ReportEngine/plugins/org.eclipse.birt.report.engine.jar/lib/

configuration位置下的Tidy.jar是一个备份，当生成报表时会被更新。

当该位置没有写权限时，应用程序就会报上面的错误。

故保证configuration位置下的读写权限，报表将会被正确生成
