Recently, we came accross the task of sending mails to every registered user in the portal. This was solved by combining the capabilities of Java mail api's and the IUser and User factory api's for Portal. ImportsThe imports are organised as import java.util.Properties; import javax.mail.Message; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; import com.sap.security.api.ISearchResult; import com.sap.security.api.IUser; import com.sap.security.api.IUserFactory; import com.sap.security.api.UMException; import com.sap.security.api.UMFactory; import com.sapportals.htmlb.Button; import com.sapportals.htmlb.Form; import com.sapportals.htmlb.GridLayout; import com.sapportals.htmlb.Group; import com.sapportals.htmlb.InputField; import com.sapportals.htmlb.Label; import com.sapportals.htmlb.TextEdit; import com.sapportals.htmlb.enum.GroupDesign; import com.sapportals.htmlb.page.DynPage; import com.sapportals.htmlb.page.PageException; GUIChoose any GUI that appeals to you. I have selected the following GUI: Form myForm = this.getForm(); Group myGroup = new Group(); myGroup.setWidth("300"); myGroup.setDesign(GroupDesign.SAPCOLOR); GridLayout gl = new GridLayout(); myGroup.addComponent(gl); Label lblSubject = new Label("Subject: "); InputField subject = new InputField("subject"); subject.setWidth("270"); gl.addComponent(1, 1, lblSubject); gl.addComponent(1, 2, subject); Label lblmessage = new Label("Message"); lblmessage.setLabeledComponentId("Message"); gl.addComponent(2, 1, lblmessage); TextEdit message = new TextEdit("Message"); message.setId("Message"); message.setCols(50); message.setRows(5); gl.addComponent(2, 2, message); myGroup.setTitle("Mailer"); Button button = new Button("Publish"); button.setText("Publish"); button.setOnClick("Publish"); gl.addComponent(3, 2, button); myForm.addComponent(myGroup); import com.sapportals.portal.htmlb.page.PageProcessorComponent; import com.sapportals.portal.prt.component.IPortalComponentRequest; import com.sapportals.portal.prt.component.IPortalComponentResponse; Mailing SectionThis section of code deals with selecting the emails of the users and sending mails to each and everyone of them individually: IUserFactory userfactory = UMFactory.getUserFactory(); IPortalComponentResponse res = (IPortalComponentResponse) this.getResponse(); IUser iuser; InternetAddress recipientAddress = null; String uniqueid, userid, email; // Mailing Properties p = new Properties(); p.put("mail.transport.protocol", "smtp"); p.put("mail.smtp.host", "server name"); p.put("mail.smtp.port", "25"); // counting & displaying all existing Portal users. ISearchResult isr; try { isr = userfactory.getUniqueIDs(); for (int i = 0; i<isr.size(); i++) { uniqueid = isr.next().toString(); iuser = userfactory.getUser(uniqueid); email = iuser.getEmail(); res.write(email); /* Mailer */ InputField sub = (InputField) this.getPageContext().getComponentForId( "subject"); String subject = sub.getValue().toString(); TextEdit body = (TextEdit) this.getPageContext().getComponentForId( "Message"); String bodystr = body.getText(); try { IPortalComponentRequest request = (IPortalComponentRequest) this.getRequest(); IUser user = request.getUser(); Session s = Session.getInstance(p); s.setDebug(false); MimeMessage m = new MimeMessage(s); InternetAddress myAddress = new InternetAddress(user.getEmail()); //VALIDATIONS TO BE DONE /* There may be some email ids to which you may not wish to send the mails to, for example a person may hold a position known as poll administrator which has its own email id. You may not wish to send redundent emails to a single person through his different ids. Validate such things here before you insert the email id as the reciepient email. */ recipientAddress = new InternetAddress(email); m.setFrom(myAddress); m.setRecipient(Message.RecipientType.TO, recipientAddress); m.setSubject(subject); m.setContent(bodystr, "text/plain"); Transport.send(m); Organise this code into a DynPage and execute. Also see to it that you have the right firewall permissions to send your mails accross from your server to SMTP server. Regards, Vijai Mohan
