请问一下是哪个地方的错误，是JDBC配置错误，还是代码错误。

谢谢你的回答!但是,我装好了jar,并设置了CLASSPATH,还是会出现同样的错误.请问是为什么呢.我的JDK版本为jdk-1_5_0_06-windows-i586-p.exe;tomcat版本为apache-tomcat-5.5.17.exe 数据库Mssql server2000我的设置如下:
JAVA_HOME: D:\jdk1.5
CATALINA_HOME: D:\Tomcat 5.5
CLASSPATH: .;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\common\lib\msbase.jar;%CATALINA_HOME%\common\lib\mssqlserver.jar;%CATALINA_HOME%\common\lib\msutil.jar
Path: %JAVA_HOME%\D:\jdk1.5\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Microsoft SQL Server\80\Tools\BINN
程序代码如下:


<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*,java.io.*"%>
<html>
<body>
以下是从Ms sql server数据库读取的数据：<hr>
<table border=1>
<tr><td>id</td><td>书名</td><td>出版社</td><td>价格</td></tr>
<%! String trans(String chi)
{
               String result = null;
               byte temp [];
               try
               {
                       temp=chi.getBytes("iso-8859-1");
                      result = new String(temp);
                }
                catch(UnsupportedEncodingException e)
                {
                        System.out.println (e.toString());
                }
      return result;
}
%>
<%

   Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
   Connection con=java.sql.DriverManager.getConnection("jdbc:microsoft:sqlserver:127.0.0.1:1433;DatabaseName=jspdev","sa","");
   Statement stmt=con.createStatement();
    ResultSet rst=stmt.executeQuery("select * from book;");
    while(rst.next())
    {
      out.println("<tr>");
      out.println("<td>"+trans(rst.getString("bookId"))+"</td>");
      out.println("<td>"+trans(rst.getString("bookName"))+"</td>");
      out.println("<td>"+trans(rst.getString("publisher"))+"</td>");
      out.println("<td>"+rst.getFloat("price")+"</td>");
      out.println("</tr>");
    }
    //关闭连接、释放资源
    rst.close();
    stmt.close();
    con.close();
    %>    
</table>
</body>
</html>

请再帮我看看．

CLASSPATH: .;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;...

1. Tomcat may not use the CLASSPATH -- I am not sure about this.
2. I won't use folder names with spaces for my Java projects.
3. %JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar are not really necessary

> 还是会出现同样的错误
Did you restart Tomcat?
Is it really the same error?? In the next post, you wrote:
java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket

> Error establishing socket
Please do a seach on this board first.
There are many many many topics about this, including the topmost one.

Please let us know whether you could solve the problem and how.
