“The value for the useBean class attribute XXX is invalid” 怎么解决？
bean
package beans;
import java.sql.*;
public class connDB
{
Connection conn=null;
Statement stmt=null;
ResultSet rs=null;
public connDB()
{
try{
Class.forName( "com.microsoft.jdbc.sqlserver.SQLServerDriver ");
}
catch(java.lang.ClassNotFoundException e)
{
System.err.println(e.getMessage());
}
}
public ResultSet executeQuery(String sql)
{
try
{
conn=DriverManager.getConnection( "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb;user=sa;password= ");
stmt=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
rs=stmt.executeQuery(sql);
}
catch(SQLException ex)
{
System.err.println(ex.getMessage());
}
return rs;
}
public int executeUpdate(String sql)
{
int result=0;
try
{
conn=DriverManager.getConnection( "jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb;user=sa;password= ");
stmt=conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
result=stmt.executeUpdate(sql);
}
catch(SQLException ex)
{
//System.err.println(ex.getMessage());
result=0;
}
return result;
}
}
一放在jsp中就提示出错，到底是那里错了呢？
