tomcat jdbc 中的 Birt 运行时连接错误
Birt runtime in tomcat jdbc connection error
我在 Birt 4.4.0 中创建了一个报告，现在想在 tomcat 8.0.26 的 birt 运行时中查看该报告。
该报告连接到 Oracle 数据库并在报告设计器中工作正常，但是当我在 birt 运行时执行它时，出现以下异常：

我将 jdbc .jar 放在 tomcat 的 lib 文件夹和 birt 运行时的 WEB-INF/lib 文件夹中。
此外，该报告使用连接配置文件。
希望有人有想法。
这个问题在评论中以某种方式得到了解决 - 但对于任何登陆此问题的人：
- 您的应用程序中需要一个包含
oracle.jdbc.driver.OracleDriver 的 jar
- 搜索包含 class in google and you will probably land at oracle's driver page (11g release or 12c release 或类似内容的罐子）。
ojdbc6.jar 或 ojdbc7.jar 可能是您要查找的内容。
- 检查您是否有正确的 jar 文件：将 jar 文件重命名为“.zip”，解压缩，然后在文件夹
oracle/jdbc/driver/ 中找到 OracleDriver.java。如果它存在，那么这个 jar 应该可以帮助您避免 ClassNotFound 异常
