Hi , Kavitha

I have successfully sent a mail.
I also come to encounter same issue of StrinOutofbondIndex Exception.

I found where the exception is encountered.

While creating the code of Message object In your code that is


Message message = new Message("kavitharajdurai@gmail.com","keenkavi@gmail.com","hai");

comment above line replace with below code

Create message object as fallowing

Message message = new Message();
message.setHeaderValue("From" , "kisna_kn@yahoo.co.in");
message.setHeaderValue("To" , "kisna_kn@yahoo.co.in");

try with above code . it may work.

i couldnt find y this exception thrown.

If possible plz give ur sample code for send mail from j2me application by using this mail4ME api.

[kisna_kn]

Hi, Kavitha

Exception are throwing due to unauthorised SMTP Server access,

because you are using Gmail SMTP Server .
They might be not granting access.

Try some other mail sever.

The code is correct what you have used .
The above exception occured in while sending message.
So , try some other SMTP server. It is sure that you are able send mail.

[traud]

de.trantor.mail.MailException: 530 5.7.0 Must issue a STARTTLS command first.

StartTLS is not about authorization, but about using a secure connection, very much like HTTPS. If your library does not support StartTLS for SMTP on port 587 (or port 25), go for port 465 which requires a SecureConnection: ssl://smtp.googlemail.com:465
However, if you did not understand that error message yourself, I recommend to read about SMTP first for example the RFCs or to get an overview a good book.

at JavaMail.commandAction(JavaMail.java:120)

You call a method which might block. You do not know which thread you might block, because you start from within your CommandListener.commandAction. If you block the wrong thread like the EventDispatcher, the whole user interface might be blocked. Even worse, if you block the main thread, the whole MIDlet could block. Your coding style is very dangerous. Always, start a new thread from within your listener and execute the code there. Please read the whole MSA (JSR 248) specification for more tweaks and tricks like this.

[kavitharajdurai]

hai thank u so much.
i used smtp server for yahoo. now mail sent through j2me application.
now my problem is its working fine in simulator. but in real device its not working. when i pressed send button there is no response. I checked this code in E-71 device.

It shows following exception in device.
de.trantor.mail.MailException: 421 service not available. closing transmission.

i find this problem in open smtpclient. problem in ftp server log in.
how to solve this problem?
did u face this problem?

Is this code working fine in ur real device???

[petrib]

On a real device, it may be that your mobile network operator is blocking SMTP access to SMTP servers that are not theirs (such as Yahoo!). Instead of Yahoo!, try using your operator's SMTP server. You can also try to see if there's a difference whether you use your operator's WAP access point vs. their GPRS Internet access point (or a Wi-Fi/WLAN access point, which is then not using your mobile network).

[kavitharajdurai]

There is no problem in network side. Because we can send mail from real device browser. but when i try to send mail through application this exception occur. "de.trantor.mail.MailException: 421 service not available.Closing transmission."
how to solve this exception.
Try to give any solution for this please.

also i tried to send with gmail smtp server. following exception occur.

How to issue STARTTLS command?

[traud]

Stay away from STARTTLS and use port 465 for SMTP. If you cannot do without STARTTLS, have a look at mujMail and how they do STARTTLS.

Hi ,

i am using yahoo smtp server.
I am facing the same problem as by kavithaa... my code is working on s40 emulator but it gives same error 421 service not available when test it on S60 emulator .

same thing happend when try it on device which is again S60 v3 device (Nokia E50)..

Hi petrib,
Your reply to kavithaa :

On a real device, it may be that your mobile network operator is blocking SMTP access to SMTP servers that are not theirs (such as Yahoo!).

is there any way out to check if mobile network is blocking SMTP ....at same time if its working on S40 emulator any reasons it is not working on S60 emulator..does this mean it is some thing related to S60 & S40 difference
as per my requirement i have to use yahoo smtp server only .
Its a while that i am stuck in this error. please give some solution for this

Thanks in advance
