jsp连接数据库问题？？？？

刚装好TOMCAT6.0   连接MYSQL测试没问题，JDK6.0
可把java.sql.删掉就才出现
在连接就出现

30:   out.print( "数据库连接成功! ");
31:  
32:   out.print( " <br> ");
33:   Statement   statement   =   conn.createStatement();
34:  
35:   String   sql= "SELECT   *   FROM   "+   tableName;

------解决方案--------------------
The type Statement is ambiguous
说明你的引用又问题，必须用java.sql.*中的类
Statement在其他的的路径下也存在，如java.bean.*中，看看你有没有import这个，去掉就可以了
