Thread: I need some help with my Servlet

Hello, iam a begginer by using servlets..

Iam doing a small project which connects to a Sql DB.
Iam using 1 doGet + 1 doPost method + 1 HtmOutputForm (inside doPost)
I have 2 buttons.
When i click on the 1st button the data from the TextFields are saved into my DB.
But when i click the 2nd button it does the same thing like the 1st Button.. but i want it to delete the data from my DB.
If iam right i must add an "IF statement" in the doPost Function to check which button is cliked ?
Can u help?

Thanks in advance.



A piece of my code
-------------------

 
public void doPost(HttpServletRequest req, HttpServletResponse res)
			throws ServletException, IOException 
		{
		Connection dbCon;
 
		req.setCharacterEncoding("utf-8");
 
                ...................
                ...................
 
		try 
		{
			Class.forName(driver);
			dbCon = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "root", "");	
 
 
			PreparedStatement st = dbCon.prepareStatement("INSERT INTO Students (id, fname, lname, age, email) VALUES (? ,? ,? ,?, ?)");			
			st.setString(1, "id");
			st.setString(2, "fname");
			st.setString(3, "lname");
			st.setString(4, "email");
			st.setString(5, "age");
 
			int j = st.executeUpdate(); 
 
			res.sendRedirect("ShowTable"); //doGet
 
		} catch (Exception e) 
		{
			res.sendRedirect("ShowTable?errormsg=" + e.getMessage());
		}
	}
 
	void printForm1(PrintWriter out) 
	{
                out.println("<b> id: </b> <input type=\"text\" name=\"id\" ><br>");
		out.println("<form action=\"ShowTable\" method=\"POST\">");
		out.println("<b> fname :  </b> <input type=\"text\" name=\"fname\" ><br>");
		out.println("<b> lname :  </b> <input type=\"text\" name=\"lname\" ><br>");
		out.println("<b> age: </b>  <input type=\"text\" name=\"age\" ><br>");
		out.println("<b> email: </b> <input type=\"text\" name=\"email\" ><br>");
		out.println("<input type=\"submit\"  value=\"Save Data\"> ");
		out.println("<input type=\"submit\"  name=\"del\" value=\"Delete Data\"> ");
		out.println("</form>");
	}
 
 
	void printAnyError(PrintWriter out, HttpServletRequest req) 
	{
		String errorMessage = req.getParameter("errormsg");
		if (errorMessage != null) 
	   	  out.println("<br><strong style=\"color:red\"> Error: " + errorMessage + "</strong>");
 
	}
