Guided Procedures - set mail smtp host

Hi,
I want to set the smtp host to use email notifications in a Guided Procedures process. So I go in the portal to:
Guided Procedures -> Administration -> GP Configuration Tool -> Interactive Forms -> SMTP Server
When I click on the Save button I get
   java.lang.NullPointerException
    at com.sap.caf.eu.gp.ui.conf.iforms.CInteractiveForms.validate(CInteractiveForms.java:382)
I tried it on another CE installation with the same result. This seems like a bug. Is there another way to set the smtp host in GP? Below the stack trace..
Regards, Kevin

Hi Kevin,
I didn't get which release of CE you are using, so I am giving you the procedure for SP3. You set the smtp through the Mail Sending tab page. Here's the procedure:
1. Go to Guided procedure ->
Administration-> Administer BMF->Clients
->select iForms Processor -> press Settings button
-> Mail Sending tab.
2. Set your smtp server in SMTP Server field.
3. Press Save button.
You can test mail sending by pressing Test button
but first you should
configure the mail of the administrator of BMF and
the mail of the administrator of the client
(iForms Processor). Please follow instruction below
BMF Administrator's mail:
1.Go to Guided procedure ->
Administration-> Administer BMF->Settings.
2.Input the mail in Administrator Mail files.
3.Press Save button.
iForms client Administrator's mail:
1. Go to Guided procedure ->
Administration-> Administer BMF->Clients
->select iForms Processor
2. Press Edit button.
3. Input the mail in Administrator Mail files.
4. Press Save button.
Hope this works out
Greets,
Petra

Mail.smtp.host ??

if I want to send a mail to example: [email protected], what do i have write in properties objet? My code is:
String host = "?????????";
String from = "[email protected]";
String to ="[email protected]";
// Get system properties
Properties props = System.getProperties();
// Setup mail server
props.put("mail.smtp.host", host);
// Get session
Session session = Session.getDefaultInstance(props, null);
System.out.println("Creo objeto sesion");
// Define message
MimeMessage message = new MimeMessage(session);
System.out.println("Creo objeto Mime");
try{
// Set the from address
message.setFrom(new InternetAddress(from));
// Set the to address
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
// Set the subject
message.setSubject("Hello JavaMail");
// Set the content
message.setText("Welcome to JavaMail");
// Send message
Transport.send(message);
catch(Exception e){
System.out.println("Falla");
}

read the tutorial carefully, everything is explained in the tasks, let this as it is
String host = args[0];
String from = args[1];
String to = args[2];
at runtime give the required details the way its given in the task!!

URGENT::Status returned by Transport.send() and problem with mail.smtp.host

Hello,
I am writing a code to send an email using JavaMail. I have added mail.jar and activation.jar in the classpath. Also I would like to mention that I am using Weblogic6.1 SP4.
A bunch of questions:
1. After calling Transport.send(), how do i know if the mail was sent successfully or not ?? Is there anyway I can handle that?
2. I am using props.put(mail.smtp.host, <some-value>). What should be this <some-value> ?? Where can I get this value from??
And is this value sufficient for the code to know that which server we are using for it? Do we need to give any URL/Port etc? How does this work?
3. Is there anything else other than smtp host, username and password to be added to props?? Do we need to create a properties file??
4. After doing these things, do I need to create a mail session in the Weblogic server also or is it a different method?
Please help me in resolving these issues.
Thanks

Thanks for your kind answers, Dr. Clap..!!
However, I will again like to ask u this:
1. As i said that I installed Weblogic 6.1 in my local machine, can I use it as the mail server? As the server is local to my machine, i know that its only me who is the incharge of it. How do I know what smtp host to use.
2. I am using this code:
public callService(ServiceRequest request) throws Exception {
     EmailRequest req = (EmailRequest) request;
     Session session = null;
     MimeMessage msg = new MimeMessage(session);
     String accNum = req.getAccountNumber();
     String toAddress = req.getToAddress().trim();
     String fromAddress = generalConfig.FROM_EMAIL_ADDRESS;
     String subject = req.getSubject().trim();
     String message = req.getMessage().trim();
     String [] arrToAddress = null;
     String fileName = "./"+accNum+".htm";
     if (toAddress != null) {
arrToAddress = convertToArray(toAddress);
     Properties props = System.getProperties();
     props.put("mail.smtp.host", "MYSERVER"); //STILL NEED TO FIGURE OUT WHAT VALUE TO PUT HERE
session = Session.getDefaultInstance(props);
     setRecipientsTo(msg,arrToAddress);
     msg.setFrom(new InternetAddress(fromAddress));
     msg.setSubject(subject);
     msg.setText(message);
MimeMultipart mp = new MimeMultipart();
MimeBodyPart text = new MimeBodyPart();
     text.setDisposition(Part.INLINE);
     text.setContent(message, "text/html");
     mp.addBodyPart(text);
     MimeBodyPart file_part = new MimeBodyPart();
     File file = new File(fileName);
     FileDataSource fds = new FileDataSource(file);
     DataHandler dh = new DataHandler(fds);
     file_part.setFileName(file.getName());
     file_part.setDisposition(Part.ATTACHMENT);
     file_part.setDescription("Attached file: " + file.getName());
     file_part.setDataHandler(dh);
     mp.addBodyPart(file_part);
     msg.setContent(mp);
Transport.send(msg); //send message
In this code, like I am using Properties class, will this code work fine(as it is) even if I dont make any Properties text file?? or is it mandatory for me to make the properties text file and to add some values to it?
I am sorry, I may sound a bit dumb, but I just need to learn it somehow.
Thanks.
P.S: convertToArray() and setRecipientsTo() are my own defined private methods.

Javamail ignoring mail.smtp.host?

Hi all,
I have some code that looks like this (OK, this is oversimplified):
private void sendMessage(SMTPMessage message, String username, String domain) throws MessagingException
bq. String mxHost = getMXHostnames(domain)[0]; \\ Properties sessionProperties = new Properties(); \\ sessionProperties.put("mail.smtp.host", mxHost ); // This line is important! \\ Session session = Session.getInstance(sessionProperties); \\ URLName targetUrl = new URLName("SMTP", mxHost, 25, null, null, null); \\ SMTPTransport transport = new SMTPTransport(session, targetUrl); Address[] addr = new Address[]() {new InternetAddress(username \\ + '@' + domain)}; \\ transport.send(message, addrArray);
username and domain are variables containing a target address, and getMXHostnames() is a function returning an array of MX host names, sorted in order of preference, for a supplied domain name (I can verify that this works, or at least that it generates an array of very plausible-looking domain names, none of which is "localhost".
When I run this code, however, I get:
javax.mail.MessagingException: Could not connect to SMTP host: localhost, port: 25
Where is that "localhost" coming from? I specified a value for mail.smtp.host, and it's not localhost! (An example is "mx1.balanced.swarthy.mail.dreamhost.com", for webmail hosted by DreamHost.)
Any help would be much appreciated.
Thanks much,
Avrom

Sorry, I should have made it a bit clearer what I'm trying to do. This isn't mail client; it is (and yes, I know the FAQ suggests that
JavaMail isn't quite appropriate for this, so maybe I shouldn't be
asking this question at all^1^) an originating SMTP server. At
some point in the SMTP server chain, you have to connect to the
receiving server. I'm hoping that I can do that directly; if I can't, I
need to find out how to discover the appropriate relay to get it there.
(Do all originators need to connect to an "upstream" server for which
they have an account? How do the upstream servers send mail, in that
case?)
"My" SMTP server, I assume you mean, is the server I have an account on and a password for. But (IIUC), the MX servers listed in a site's WHOIS entry are public receiving servers--they're what smtp.google.com (for example) uses to deliver messages to email addresses at that web site. Surely they can't require usernames and passwords, because they need to have a general ability to receive email from outside. (These are different from SMTP originators, which are really only for the use of a select few.)
(Anyway, why would you list servers in a WHOIS entry when they require an account? You can inform your account holders of your SMTP servers without using WHOIS).
bshannon, sorry, but there's something I'm failing to see in the
samples (possibly due to my not seeing it, rather than its not being there). All of them assume you use your session object in the
construction of the MimeMessage: new MimeMessage(session). I've already
received and processed a MimeMessage from the actual client; if I don't
intantiate my own transport, how do I tell the SmtpMessage about my
session (with customized properties, especially smtp host)?
I really don't want to put the session in the message constructor if I
can possibly help it--because the same MimeMessage might go to a bunch
of different receiving smtp hosts (if it has a long to line, for
example). Re-reading the content for each of them seems wildly
inefficient compared to creating a single Mime message, and then
creating different sessions to send the message to different places.
drvijayy2k2, I understand that thread and in fact have posted on it. But again, that person was trying to create a client that connected to an SMTP provider. I'm trying to be the SMTP provider, and deliver mail to receiving servers.
^1^On the other hand, I've looked at extensible Java servers available on the net, and they all really seem to be primarily intended as SMTP receivers, not SMTP originators. I've actually got a (home-brewed, and currently pretty basic) receiving SMTP system working just fine (and the server component of my originator fine; it's the bit that sends the mail along that I'm having trouble with), but I need to provide a way to send mail, not just receive it. If JavaMail isn't robust enough (as the FAQ suggests) for this purpose, then it looks like eventually I'll need an entirely home-brewed system, but for my prototype, time to completion is rather more important than real robustness. I don't expect the prototype to need to handle a big load, for example.

Setting 'mail.smtp.localhost' to make things work

Hello
I was getting this error with my initial attempts to send myself an email using JavaMail:
javax.mail.MessagingException: 501 Syntactically invalid HELO argument(s)
After hunting around for a while I came across references to doing this:
props.put( "mail.smtp.localhost", "localhost" )
So I tried it, and it works!
I'm happy about that, but I would like to find out why? I just cannot seem to find an answer anywhere.
I run Windows XP, and my hosts file has not been changed - localhost is still there, as shipped. When I call this:
InetAddress.getLocalHost().getHostName()
I get the $COMPUTERNAME value for my PC which happenes to be "HARRY_PC".
My real concern is what will happen when I deploy my application to other machines - is this little 'hack' likely to break things?
Hmm...
Many thanks!

Thanks for that link.
I had actually looked at it earlier, and next to the 'mail.smtp.localhost' property it reads:
Local host name. Defaults to InetAddress.getLocalHost().getHostName(). Should not normally need to be set if your JDK and your name service are configured properly.
Which begs the question: how should my JDK and/or my name service be configured?
I am sorry to say that I have no idea what JDK configurations to consider, and I do not think a name service is used in my simple test application.

Mail settings for Guided Procedures

Hi,
I'm having problems having GP send mails.
The settings in the GP Administration are correct. I can send test mails to myself without problems, and did the setup that is described here: [Re: Guided Procedures - set mail smtp host]
Also, I'm sure that my user has an e-Mailaddress and the like, I've set it up properly on R3. Also, when trying to send a mail to a static address (just give it as a value) it still generates problems.
Now when I go to the log, I get these errors, which are odd, considering mail.sap.org is NOT the SMTP server I set up!!
Unknown SMTP host: mail.sap.corp
javax.mail.MessagingException: Unknown SMTP host: mail.sap.corp;
nested exception is:
java.net.UnknownHostException: mail.sap.corp
The question is fairly simple: Where does it say that the SMTP server is that? It's certainly not in Administration > Administer BMF > Clients as it's set correctly there!
Help would be, as always, greatly appreciated!

Hi,
So, to start the Config Tool, double click the configtool script file from <SAP_install_dir>/<system_name>/<instance_name>/j2ee/configtool directory.
When you open it, navigate to cluster-data -> template <name of template> -> instance <name of instance> -> services -> caf/eu/gp/model.
The template represents the usage type installed on your server (for example, EP). It consists of one or more instances that can be configured in a different way.
Next, modify the required system parameters (in your case smtp.server and smtp.service_user_mail) :
a. On the Service properties screen, select a parameter from the table.
b. In the Custom value field, enter a value for the parameter.
c. Choose Set.
The new value appears in the Value column.
In the Template value field, you can see the default value (if any) for the parameter you have selected. You can restore the default template value for any parameter by choosing Restore to Template.
So here is the documentation regarding the Config tool as a whole:
http://help.sap.com/saphelp_nwce10/helpdata/en/e8/f48b33f9a3423c9e688dfa56330e79/content.htm

Javax.servlet.ServletException: Unknown SMTP host

Hi
I am using tomcat and trying to send emails. I keep getting a javax.servlet.ServletException: Unknown SMTP host error.
I initially thought the problem was with the line: props.put("mail.smtp.host", "makethegrade.co.za"); But i checked the smtp info with the guys i'm hosing with and they said its right
I am currently setting the fields manually, so it can't be a problem with passing data around in the webpage
In my WEB-INF/lib i have jaf-1.0.2 and javamail-1.4.1 (i.e. mail.jar and activation.jar)
The code for my mailer bean is:
package mailer;

Any help or any pointers to a place to find a solution would be deeply appreciated
Thanks

All I can see is that you are running this in a web application. In most web application containers there's a place where you configure your mail providers and mail sessions. You seem to be ignoring that (you aren't using JNDI to get a session for example) but you are getting the default instance, so perhaps that uses that configuration anyway.

"mail.smtp.from" is not working for me

There seem to be zero other posts like this, so I'm probably just doing something obviously dumb,
but for me, setting the mail.smtp.from property seems to have no effect.
The debug output shown below says to me that while the property has been set, the transport is using the From address not the value of the property.
Any suggestions for what might be causing this?
//set:
Properties prop = new Properties();
prop.put("mail.smtp.host", SMTPServers ); //see below
prop.put("mail.smtp.from","[email protected]");
sessions{i} = Session.getInstance(prop, null);
//use:
System.out.println("(session mail.smtp.from is '" + sessions{i}.getProperty("mail.smtp.from") + "')");
sessions{i}.setDebug(true);
mimeMsg = generateMimeMsg(msg, sessions{i});
Transport.send(mimeMsg);
//the console output:
(session mail.smtp.from is '[email protected]')
DEBUG SMTP SENT: mail from: <[email protected]>
//note - Looks like this forum's software is grabbing my square brackets,
so {i} in this post stands for opensquarebracket i closesquarebracket...

I haven't read the FAQ, at least not lately. I'm just stating an interpretation of the behaviour that you described.
Normally, system properties are used to specify defaults that can be overridden. It doesn't make sense to me to have to set a system property to "override" something that you do normally in your code. As a designer, it's obvious to me that the system property should be the default value for "from" and it should be possible to override that on a message-by-message basis by explicitly setting (and thus overriding) the from-address. And you confirm that it really does work that way. I'm not surprised at all. I would suggest that if the FAQ doesn't say that, then it needs to be fixed.

Thanks for your help.

Will there be any problems if i execute init.xml after configuring SMTP host??

Java mail - unknown host

hi
I am quite new to java.. I have written some code that requests user input to create a mail then should be sent.
I am using my companies smtp address to send it through but i keep getting the exception unknown host, however when a colleague tries to run my code on there pc on the same network it works correctly. Really impressed my code works but i want to play with it and add things to it and cannot!
Is there any settings or rights i should have on my pc to enable me to get this code to work. Also does anyone know of any external smtp hosts i can send mails from.
I can ping the smtp from dos and that works but will not recognise in code
thanks

Getting nested exception(Unknown SMTP host)

hello
i have written a simple mailclient.i am running the following programme from my local machine which is under proxy server.
public class MailExample {
public static void main (String args[]) throws Exception {
String host = "mail.ab";
String from = "[email protected]";
String to = "[email protected]";
Properties props = System.getProperties();
props.put("mail.smtp.host", host);
Session session = Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO,
new InternetAddress(to));
message.setSubject("Hello JavaMail");
message.setText("Welcome");
Transport.send(message);
This host is some other machine.
i am getting nested exception as unknown SMTP host.
please help.
thanks in advance

Unknown host: it is telling you that it can't find the host you told it to look for. Either you gave it the name of a system that does not exist, or that system does not have an SMTP host running on it. I would guess the first reason, as "mail.ab" does not look right to me. (What country is "ab" and why is there only one mail server in the entire country?)
