BIRT 4.3.2错误，在线求助

[浪里油条]

用birt想连接数据库，把数据展示出来用birt做报表，版本是4.3.2 连接mysql.如果报表没有涉及连接数据库，很正常，但是如果是有需要连接数据库的，一直报错，按照网上很多种做法都没用，在apache-tomcat-7.0.54\webapps\birt\WEB-INF\lib 下面放驱动包没用，还有说在WEB-INF/platform/plugins/org.eclipse.birt.report.data.oda.jdbc_4.3.2.v20140211-1400/drivers下面放驱动包，可是4.3.2的版本根本就没有这个目录。 报错如下：

驱动包放在apache-tomcat-7.0.54\webapps\birt\WEB-INF\lib 里，如果你工程重新编译就会清除的， 你放到工程的\WEB-INF\lib 里呢

我今天也出现这个问题了，最后是在eclipse中的report的那个视图那里，配置数据源信息的那里，下面有三个按钮，中间是test connection，第一个按钮是manager drivers，在这里可以添加数据库驱动包，添加好之后，再test connection就success了
