You cannot mix Swing with servlets. Servlets must generate HTML or other formats suitable for display in a browser.

Hi,
This is my source code.



import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class NewServlet extends HttpServlet {

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
try {
out.write("Welcome");
NewJFrame o=new NewJFrame();
o.show();
// NewJFrame obj = new NewJFrame();
// out.write("JFrame name="+obj.getName());
// obj.setLocation(500, 500);
// obj.show();
// obj.setVisible(true);

class NewJFrame extends javax.swing.JFrame {

/** Creates new form NewJFrame */
public NewJFrame() {
initComponents();
}

private void initComponents() {

jButton1 = new javax.swing.JButton();

setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

jButton1.setText("jButton1");

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING).addGroup(layout.createSequentialGroup().addGap(150, 150, 150).addComponent(jButton1).addContainerGap(177, Short.MAX_VALUE)));
layout.setVerticalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING).addGroup(javax.swing.GroupLayout.Alignment.TRAILING, layout.createSequentialGroup().addContainerGap(166, Short.MAX_VALUE).addComponent(jButton1).addGap(111, 111, 111)));

pack();
}// </editor-fold>
// Variables declaration - do not modify
private javax.swing.JButton jButton1;
// End of variables declaration
}
out.write("******************Welcome");
} finally {
out.close();
}
}
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}

protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
}



Please tell me what are the changes to be made in code to make jframe visible.
When i run this servlet from netbeans IDE ,the jframe is pop uped.But i trying to run from tomcat deployed folder ,jframe is not pop uped.I have seen log also,in that jframe object is created but it is not visible in browser.
