private Object executeUpdate;
private static class executeUpdate {
public executeUpdate() {
}
}
private Object rs;
private Object st;
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException, SQLException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
String name=request.getParameter("t1");
String abc=request.getParameter("t2");
aaaa c1=new aaaa();
try{
String Sql="insert into teacher1(id,name) values('"+name+"','"+abc+"')";
c1.st.executeUpdate(Sql);

aaaa c12=new aaaa();
try{
String Sql="Select * from teacher1";
。 c12.rs = c12.st.executeUpdate（SQL）;
out.println("<table border=1>");
while(c12.rs.next()){
String name1=c12.rs.getString("id");
String abc1=c12.rs.getString("name");
out.println("<tr>");
out.println("<td>"+name1+"</td>");
out.println("<td>"+abc1+"</td>");
