补充:在读取数据库上面还有一段helloworld的代码,已经可以运行了.完整的代码是:
import java.io.*;
import java.text.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;public class HelloWorldExample extends HttpServlet { public void service(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
ResourceBundle rb =
ResourceBundle.getBundle("LocalStrings",request.getLocale());
response.setContentType("text/html");
PrintWriter out = response.getWriter(); out.println("<html>");
out.println("<head>"); String title = rb.getString("helloworld.title"); out.println("<title>red_hello</title>");
out.println("</head>");
out.println("<body bgcolor=\"white\">");
out.println("<h1>red</h1>");
out.println("<h1>");
try{
Class.forName("sun.jdbc.odbc.JbdcOdbcDriver");
Connection conn =
DriverManager.getConnection("jdbc:odbc:Customers");
Statement stmt =conn.createStatement();
String strSQL="select companyname from company";
ResultSet rs=stmt.executeQuery(strSQL);
ResultSetMetaData rsmd =rs.getMetaData();
int colcount=rsmd.getColumnCount();
int count=1;
while(rs.next())
{
out.println("<tr><td>");
String name=rs.getString(1);
out.println(name);
out.println("</td></tr>");
}//while
}catch(Exception e){
System.out.println(e);
}out.println("</h1>"); out.println("</body>");
out.println("</html>");
}
}页面显示的已经是"RED"了.

sun.jdbc.odbc.JdbcOdbcDriver以后细心点~~~~~~~~~~~~~~~~~
servlet全贴出来看看！！
stemp=rs.getString("companyname");
s2 = new String(stemp.getBytes("iso8859_1"),"GBK");
还有response.setContentType("text/html;charset=GBK"); 也不行.也试了.gb2312
还有iso8859_1到底是不是这样,我看也有人写iso8859-1.(不是下划线)都试了也不行.
明天就结贴.再试不出来我就找同学去了.真不好玩.
