我写的一个BEAN，但是有问题~大家帮我！

[hsnh1981]

package book;
import java.util.*;
import java.sql.*;

public class book
{
private ResultSet rs = null;
private Statement stmt = null;
private Connection con = null;

public void openDate(String url, String us, String ps)
{
try
{
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
con = DriverManager.getConnection(url, us, ps);
stmt = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
}
catch (Exception e)
{
e.printStackTrace();
}
}

public void closeDate()
{
try
{
stmt.close();
con.close();
}
catch (Exception e)
{
e.printStackTrace();
}
}

public ResultSet secrchSql(String sql)
{
try
{
rs = stmt.executeQuery(sql);
}
catch (Exception e)
{
e.printStackTrace();
}
return (rs);
}

public void editSql(String sql)
{
try
{
stmt.executeUpdate(sql);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}

解决给分！我确保数据库没问题！
就是这个JAVA文件生成的CLASS文件用JSP连接时错误！我保证CLASS的包和文件的位置对！
问题在这个JAVA程序本身！

错误信息打出来

[doway]

package book;
public class Book { ...

包名和类名不应该相同。

还有我每次用DW2004打开JSP文件时里面的中文就显示成乱码，怎么回事？

[doway]

JSP 文件中有非法字符，另外就是前边说的 book.book 太难看了，book.Book 还说得过去。

[HengHuan]

Unable to compile class for JSP
编译出现问题，引用失败

book.book GO = null;
book.book 没有被new出来啊

路过，帮顶——
