Question

我是BIRT的新手。我正在尝试使用POJO Datasource，它本质上使用一个独立的jar，它有一个代码来查询Oracle DB。当我添加POJO数据源并预览结果时，我看到以下错误。任何人都可以建议我是否需要做任何特别的事情。我在运行时属性和设计时属性中添加了独立jar。

Answer 1

将Oracle JDBC驱动程序ojdbc6.jar（或ojdbc7.jar）复制到子目录%ECLIPSE_HOME%\plugins\org.eclipse.birt.report.data.oda.jdbc_*\drivers中。

..... jdbc _ * ...目录的确切名称取决于您的BIRT版本。
