Converting emails to servlet requests; servlet responses to emails

Hello,
I had asked this question in the Servlet forum. They directed me to here.
I've some servlet applications that posted by HTML forms with file attachements and other HTML fields.
I want to add email support to my servlets. So, users should be able post and recieve their data by emails.
But, I don't want to add email handling tasks to the current servlet applications. I need a middleware application between end users and my servlets that converts emails to servlet requests, and servlet responses to emails.
Here are the steps:
1- End user sends email with attachments.
2- Emailed data is converted to servlet request by a middleware application.
3- Servlet request is processed by my current servlets.
4- Servlet response is sent to middleware application.
5- Middleware application emails servlet reponse to end user as email.
If I can do that, I will not have to add emailing codes to my current servlets. do you know a product doing that ? Or, can you give me a direction ?
thanks...

Have you looked into JMS?

Send email from j2me through servlet

Hi people,
i hope you can help me because i am new in network programming.
I am trying to send email from j2me to googlemail account I have 2 classes EmailMidlet (which has been tested with wireless Toolkit 2.5.2 and it works) and the second class is the servlet-class named EmailServlet:
when i call the EmailServlet, i get on the console:
Server: 220 mx.google.com ESMTP g28sm19313024fkg.21

   } 1.when i print "to" in EmailServlet also:
String to = request.getParameter("to");
      System.out.println("____________________________to" + to); it show null on the console :confused:
2. ist this right in case of googlemail.com?
smtpSocket = new Socket("smtp.googlemail.com", 25); I would be very grateful if somebody can help me.

Problem sending email using javamail in servlet

I try this code and make some changes of my own http://forums.sun.com/thread.jspa?threadID=695781.
When i run the program the confirmtaion shows that the mail has been sent, but when i check in my inbox there's no the message. I'm using gmail and need to authenticate the username and password. I guess the error caused in the servlet.
Here's the code for my servlet :
import java.io.*;
import java.util.Properties;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.mail.internet.*;
import javax.mail.*;
public class ServletEx extends HttpServlet {
   public void doPost(HttpServletRequest request, HttpServletResponse response)
         throws IOException, ServletException {
      System.out.println("____emailservlet.doPost");
      response.setContentType("text/plain");
      PrintWriter out = response.getWriter();
      System.out.println("______________________________");
      out.println();
      String to = request.getParameter("to");
      System.out.println("____________________________to" + to);
      String subject = request.getParameter("subject");
      String msg = request.getParameter("msg");
      // construct an instance of EmailSender
      System.out.println("servlet_to" + to);
      send(username, to, subject, msg);
      //send("[email protected]", to, subject, msg);
      out.println("mail sent....");
        String username = "[email protected]";
        String password = "my_password";
        String smtp = "smtp.gmail.com";
        String port = "587";
   public void send(String username, String to, String subject, String msg) {
        Properties props = new Properties();
        props.put("mail.smtp.user", username);
        props.put("mail.smtp.host", smtp);
        props.put("mail.smtp.port", port);
        props.put("mail.smtp.starttls.enable","true"); // just in case, but not currently necessary, oddly enough
        props.put("mail.smtp.auth", "true");
        //props.put("mail.smtp.debug", "true");
        props.put("mail.smtp.socketFactory.port", port);
        props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.socketFactory.fallback", "false");
        SecurityManager security = System.getSecurityManager();
        try
            Authenticator auth = new SMTPAuthenticator();
            Session session = Session.getInstance(props, auth);
            //session.setDebug(true);
            MimeMessage message = new MimeMessage(session);
            message.setText(msg);
            message.setSubject(subject);
            message.setFrom(new InternetAddress(username));
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
            Transport.send(message);
        catch (Exception mex)
            mex.printStackTrace();
   public class SMTPAuthenticator extends javax.mail.Authenticator {
        public PasswordAuthentication getPasswordAuthentication(String username, String password)
            return new PasswordAuthentication(username, password);
}Actually it's been a long time for me to develope this program, especially with the authenticate smtp. Any help would be very appreciated :)

Accordingly to your stackTrace, I think that you miss some utility jar from Geronimo app. server.
As you are using Application server that is J2EE compliant, so there is an own JavaMail implementation embeded and used by the Server. To fix this problem you have to find and add to your calsspath a jar-file that contains Base64EncoderStream.class

Limit of Weblogic for servlet requests

          Hi,
          Could someone tell me what is the limit on the number of servlet requests per
          second a weblogic server
          can handle.. We are facing some performance issue.. Would like to know the limit
          that WLS server can process
          at a time.
          Thanks in advance,
          rgds, rams


Thanks Robert - I had the same results on 4-way E420 (and slightly less for
          session-less JSP). Don't you think it can be potentially useful to have some
          'baseline' results to be available for some most popular hardware/JVM configurations ?
          (Of course, these numbers have nothing to do with an actual application performance, but
          they are useful in establishing the 'upper limit' - something like HelloWorld servlet,
          HelloWorld JSP with session=false, HelloWorld JSP with sessions enabled).

Cannot process an HTTP request to servlet [Faces Servlet] in [wcb] web application

Hi All
l am working on a Wcem 3.0 with Trex with ERP and WAS 7.3.

Hi Steffen,
Thanks for promt response.
But when I checked with Basis team as of now there are not yet configured TREX, only WCEM components has been configured in WAS 7.3. When they are configuring WCEM components HTTPS protocol not configured.
But for past 2 weeks I am able to see the below screen using http://<host>:<port>/wcb/index.html url.
But now I am getting The website cannot display the page error.
Please clarify me if anything is wrong from my side. And also pl let us know which configurations I have to check for fixing the issue.

Call methods (which are in the servlet) in my response page

Hello !
I want to call methods which are in the servlet ( its name is ServletRecap) BUT the call is made in the response page which is generated by the servlet ServletRecap !
I just want to allow the user to update his choice in the response page.
example: i choice A in the initial form but i change my mind and now i want to choice B in the response page : the choice have to be update in the database.
the insertion in the DB is made by a method in the servlet : so i have to recall the method in the response page!

I resume : how can I call a method in my servlet into my response page (in jsp).
the servlet generate this response page and i just want to update the choice of my user.
Thanks !!

I resume : how can I call a method in my servlet into my response page (in jsp).Don't do that. Put the message into a plain old Java class which can be called from both the servlet and the JSP.

Does Weblogic 5.1 support the STANDARD javax.servlet.request.X509Certificate attribute?

Hello!
My strong suspicion from looking at the Weblogic SSL documentation on
http://e-docs.bea.com is that WebLogic SSL does not put any client-side
certificates into the 'javax.servlet.request.X509Certificate' attribute
of a servlet's HttpServletRequest (as an array of
java.security.cert.X509Certificate instances).
Currently, it appears that Weblogic uses a proprietary attribute name
('weblogic.security.somethingOrOther') and returns instances of the
deprecated Java 1.1 java.security.Certificate class.
When will Weblogic support this aspect of the Servlet 2.2 specification,
if it doesn't already?
Regards,
James W.

I just verified this with the Java doc. Either the Java documentation is
incorrect or we are still using the older version of the certificate
encoding class. I will check on this, we may have fixed it in a subsequent
service pack.
Thanks,

Xhtml call to servlet not returning response, not calling servlet

I have xhtml in a web app making a call to a servlet but the response from the servlet is not displaying. The original xhtml displays after the submit button is pressed.

You have a template. That template doesn't have for example a h:form of its own in which the body content is placed right? Nested forms don't work.
Also for the next time, use \ tags to post code; that makes it actually readable. As you can see, the forum is now trying to interpret some special characters for formatting.

Sending emails+attachment from a servlet

Hi all,
I'd like to send emails from within my servlet. There must be a possibility to attach a file that has been uploaded to the server in a previous request.
Currently I'm using sun.net.smtp.SmtpClient to send simple emails.
Does the sun-smtp-package provide a way to attach a file to an email?
regards
Steffen

I'm not sure but I think the sun.net.smtp package is part of J2EE. I didn't need to download it. You will need a Base64-Encoding algorithm for transforming the file-data (the attachment) into the email message. OReillys servlet package provides a class for this (www.servlets.com).
Below is an example how to send an email with a file attached to it. You will have to specify the name of an SMTP-Server. If you do not have one you can (for testing purposes) direct the email into a text file.
try{
     String host = /** @todo place your smtp-server name or IP here */
     SmtpClient smtp = new SmtpClient(host);
     smtp.from(from);
     smtp.to(toList);
     PrintStream out = smtp.startMessage();
     Base64Encoder b64e = new Base64Encoder(out); // Base64Encoder is also a Stream which we will only use for the attachment-data
     /* uncomment this if there is no smtp-server. The email will be stored in a file
     File fEml = new File(/** @todo add your filePath here */+File.separatorChar+"out.eml");
     PrintStream out = new PrintStream(new FileOutputStream(fEml));*/
     out.println("From: "+from);
     out.println("To: "+toList);
     out.println("Subject: "+subject);
     out.println("Date: "+date.toString());
     out.println("MIME-Version: 1.0");
     // we have to declare the email multipart/mixed to notify the email client that this mail contains sub parts of different content-types
     out.println("Content-Type: multipart/mixed;");
     // the boundary-string separates the sub parts (just like in HTTP-Multipart-Requests)
     out.println("\tboundary=\"----=_next_part\"");
     out.println("\r");
     out.println("This is a multipart message in MIME format.");
     out.println("\r");
     // first sub part starts here - its the text message
     out.println("------=_next_part");
     // this sub part contains only plain text
     out.println("Content-Type: text/plain;");
     out.println("\tcharset=\"iso-8859-1\"");
     out.println("Content-Transfer-Encoding: 7bit");
     out.println("\r");
     // Message text goes here
     out.println(/** @todo place your message here */);
     out.println("\r");
     // now the attachment
out.println("------=_next_part");
out.println("Content-Type: application/octet-stream;");
out.println("\tname=\""+fileName+"\"");
out.println("Content-Transfer-Encoding: base64");
out.println("Content-Disposition: attachment;");
out.println("\tfilename=\""+fileName+"\"");
out.println("\n");
// encode file piece by piece
File f = new File(/** @todo place your filepath here */+File.separatorChar+fileName);
FileInputStream fis = new FileInputStream(f);
int i = 0;
do{
byte[] content = {0, 0, 0};
i = fis.read(content, 0, 3);
if (i != -1){
               b64e.write(content);
     }//if
}while(i != -1);
fis.close();
fis = null;
f = null;
     // this is it, all there's left to do is to flush our output-stream and clean up
     out.flush();
     b64e.close();
     out.close();
     b64e = null;
     smtp.closeServer();
     out = null;

}catch(IOException ioe){

How can i send xml file with a http servlet request

Hi
Please tell me how can I send a xml file into http servlet request.
I have a servlet(action) java file.From this servlet I have generate a xml file. Now I need to send that xml file to another servlet with http servlet request object.
Dave.

When you say you have generated an XML file what do you mean?
Is it a file stored on disk? Then pass the file path as a string to the servlet.
Is it stored in memory as an object? The pass a reference to the object to the servlet.
Or are you asking how to communicate between servlets?
Look in the JavaDocs for the RequestDispatcher class. You can use this class to forward the request to another servlet. Data can be passes using the RequestDispatcher by storing it as attributes using the request getAttribute and setAttribute methods. Also described in the JavaDOcs.

Servlet with 2 Response Streams

I want to create a Servlet with 2 response streams. I need to use 1 response Stream to send Continuous Updates received on the server
and the other response Stream would be used to send Heartbeats to the Client. I tried to create the Servlet but the response I create to send the continuous data just stops sending data to the Client after many attempts. In this attached Servlet, The response for continuous data stopped after 150 refreshes.
Please let me know how to fix the issue. I tried reset() too but does not seem to work. Will very much appreciate any help.

HTTPS Servlet requests

          After installing service pack 9 from WL5.1, HTTPS servlet requests result in the
          browser returning a server error. Issue 41888 of sp9 seems to address this. We
          were previously running service pack 6 and didn't experience this problem. Any
          ideas?


Have you installed SP9 properly?
          I just tried accessing example servlets on Https protocol and i don't see any
          errors.
          Could you tell us what problems you are facing? Any test case?

Servlet to servlet communication in the same server

Hi everybody!
I have two .wars in the same JBoss + Tomcat web server. Both .war have their own login system throught j_security_check. I'm using Struts for development and Win 2003 for OS.
I want to login into .war 1 and "use" Action class of .war 2. Is there any way I can do this? I found piece of code to put response and request to other servlet (from servlet 1) with RequestDispatcher, but how can i catch this new response and request in .war 2 (servlet 2)? And how to fix login in servlet 2?
Piece of code that i found:
ServletContext context = session.getServletContext();
RequestDispatcher rd = context.getRequestDispatcher("/ServletName/Action.do");
rd.include(request, response); Tnx,
Stanislav

Not realy...
The way I do it is that I put the data I need in webapp2/Servlet2 in the session >in the webapp1/Servlet1 and then redirects. The session should be managed >over the different web-applications.
Have to check the documentation if you need to set something to have >cross-application session...How can you share session between two different .war files (i presume different context and diferent session)? In mine situation i have two different realm, also...

How can i do the servlet to servlet communicaion usingservlet context

public void doGet(HttpServletRequest request, HttpServletResponse response)
               throws ServletException, IOException {
          response.setContentType("text/html");
          //ServletContext context = null;
          PrintWriter out = response.getWriter();
          RequestDispatcher rd=request.getRequestDispatcher("/second");
          rd.forward(request,response);
          out.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
          out.println("<HTML>");
          out.println(" <HEAD><TITLE>A Servlet</TITLE></HEAD>");
          out.println(" <BODY>");
          /*out.print(" This is ");
          out.print(this.getClass());
          out.println(", using the GET method");*/
          out.println(" </BODY>");
          out.println("</HTML>");
          out.flush();
          out.close();
Here I have used request.getRequestDispatcher("/second ").. it wil cal the second servlet...
But how can i cal the second servlet using context.requestDispatcher(" ") inside the paranthesis what i wil give?
plz some one help me..

request.getRequestDispatcher("/second ") is the same as context.requestDispatcher("/second ") .
The requestDispatcher from the request object can take a relative path but if the path starts with a '/' it is interpreted as relative to the context root. The RequestDispatcher from the context can only take paths that start with '/' and are relative to the context root.
