I was trying to develop the Feedback form. I'm attaching the Source code below. According to the experts ...everybody suggested that..instead of using Service providers for sending mail...everybody using KM Services for sending mails. we already installed KM and collaboration.
Can anyone..pl help me..to achive this feedback development.
Kindly send me the code if anyone developed same kind of form using KM Services for sending mail...
or do correct me my code...what went wrong.
package Com.pradeep.Feedback;
import java.util.GregorianCalendar;
import java.util.Properties;
import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import com.sapportals.htmlb.enum.ButtonDesign;
import com.sapportals.htmlb.enum.DataType;
import com.sapportals.htmlb.enum.GroupDesign;
import com.sapportals.htmlb.enum.TextViewDesign;
import com.sapportals.htmlb.page.DynPage;
import com.sapportals.htmlb.event.Event;
import com.sapportals.htmlb.page.PageException;
import com.sapportals.htmlb.*;
import com.sapportals.portal.htmlb.page.PageProcessorComponent;
public class feedback  extends PageProcessorComponent {
     public DynPage getPage() {
          return new MyDynPage();
     public class MyDynPage extends DynPage {
          private final static int INITIAL_STATE = 0;
          private final static int SENTMAIL_STATE = 1;
          private final static int ERROR_STATE = 2;
          private final static int NO_FEEDBACK = 3;
          private int state = INITIAL_STATE;
          private String email_from;
          private String txtdescr;
          private String error_messg;
Things to initialice once per session.
          public void doInitialization() throws PageException {
               state = INITIAL_STATE;
Will be called if forms with data was send.
          public void doProcessAfterInput() throws PageException {
               InputField myInputField = (InputField) getComponentByName("EMAIL_ADDR");
               HtmlEdit txtdescr = (HtmlEdit)getComponentByName("Edit_Text");
               if (myInputField != null) {
                    this.email_from = myInputField.getValueAsDataType().toString();
               if (txtdescr != null) {
                    this.txtdescr = txtdescr.getText();
Will always be called before output. So this is the method in which
the components will be placed and set.
                    public void doProcessBeforeOutput() throws PageException {
                         System.out.println("doProcessBeforeOutput");
