我创建了BIRt报告，它正在我的localhost tomcat6上运行，如果我在linux服务器上部署战争，它会向我显示这些异常。
mysql-connector-java-5.0.8-bin.jar 是我的mysql连接器放在lib文件夹中，如果我更改密码则抛出密码异常，表示jar正确放置在项目中，但是当mysql的所有凭据都正确时，我正在获得此异常跟踪。

您的异常根本原因是 -
java.lang.ClassNotFoundException: com.mysql.jdbc.Statement$CancelTask
和
java.lang.NoClassDefFoundError: com/mysql/jdbc/Statement$CancelTask
尝试解决这些错误。
可能是因为Jar的版本不正确。
答案 1 :(得分：0)
我刚刚从lib文件夹中删除了mysql jar，现在它运行良好......
