<p>Hi</p>

I have no idea how to do this...the previous page is retrieve.jsp which has the data based on form input with edit and Delete button end of each row, when i click delete it shd alert me....This is my servlet code:</p>

<p>DeleteData.java</p>

<p>[code]
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
import java.util.*;</p>

<p>public class DeleteData extends HttpServlet {</p>

<pre class="prettyprint">public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    response.setContentType("text/html");
    PrintWriter out = response.getWriter();
</code></pre>

<p>out.println("<title>Delete Page</title>" + "<h1 align=\"center\"></h1>" + "<body bgcolor=#99CCFF>");
out.println("<center><td align=\"center\" width=\"37\"> <strong><img title=\"Go back\" src=\"Undo.gif\" width=\"20\" height=\"20\" onClick=\"javascript:history.back()\" style=\"vertical-align:middle;\" onMouseOver=\"this.style.cursor='hand';\"></strong></td></center>");
        System.out.println("Oracle 10g Connect Example.");
        Connection conn = null;
        String url = "jdbc:oracle:thin:@10.44.6.75:1529:nrsprd";
        String driver = "oracle.jdbc.driver.OracleDriver";
        String user = "root";
        String pass = "root";
        String Cabinet =request.getParameter("Cabinet");
        Statement stmt;
        try {
            Class.forName(driver).newInstance();
            conn = DriverManager.getConnection(url, user, pass);
            System.out.println("Connected to the database");
            ArrayList al = null;
            ArrayList userList = new ArrayList();
            String query = "DELETE FROM Carr_ethernet  WHERE Cabinet='" + Cabinet + "'";
            stmt = conn.createStatement();
            int i = stmt.executeUpdate(query);
            System.out.println("query" + query);
            if (i > 0) {</p>

<pre class="prettyprint">            out.print("&lt;br&gt;");
            out.print("&lt;table  align=\"center\" style=\"background-color: white;\"width=\"50%\" border=\"1\"&gt;");
            out.print("&lt;tr&gt;&lt;th&gt;Data Deleted Successfully&lt;/th&gt;&lt;/tr&gt;");
            out.print("&lt;/table&gt;");
</code></pre>

<p> }
            conn.close();
            System.out.println("Disconnected from database");
            stmt.close();
            conn.close();
        } catch (Exception e) {
            e.printStackTrace();
        }</p>

<pre class="prettyprint">}
