一个很奇怪的问题！如果能解决 不够分您开腔！
我有一个.html页面．把里面的值提交给一个servlet 具体代码如下：
package model;
import java.io.*;
import javax.servlet.http.*;
import java.util.*;
import java.sql.*;
import javax.servlet.*;
public class dcservlet extends HttpServlet {
private static final String CONTENT_TYPE= "text/html;charset=GBK ";
private String comeOutStr= " ";
private int comeOutInt=0;
private static Connection con;
private Statement stmt;
private static final String drivername= "org.gjt.mm.mysql Driver ";
private static final String url= "jdbc:mysql://localhost/zqswork02?user=root&password=root&useUnicode=true&characterEncoding=gb2312 ";
public static Connection getCon() throws Exception {
try {
Class.forName(drivername);
con=DriverManager.getConnection(url);
return con;
} catch (SQLException e) {
System.err.println(e.getMessage());
throw e;
}
}
public Statement getStmtread() {
try {
con=getCon();
stmt=con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY);
return stmt;
} catch (Exception e) {
System.err.println(e.getMessage());
e.printStackTrace();
}
return null;
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType(CONTENT_TYPE);
PrintWriter out = response.getWriter();
out.println( " <!DOCTYPE HTML PUBLIC \ "-//W3C//DTD HTML 4.01 Transitional//EN\ "> ");
out.println( " <HTML> ");
out.println( " <HEAD> <TITLE> A Servlet </TITLE> </HEAD> ");
out.println( " <BODY> ");
