a problem about java mail client program

lunarstyle · #1 (**permalink**) 05-27-2007, 07:14 PM

I have downloaded java mail client program class files forım the page at this link Java Tips - How to create an e-mail client in Java . And I downloaded Javamail api. I compiled the files and run the program with Netbeans. in the connection settings panel, I can not connect to the mail server. It is trying to connect and waiting so long. At last I'm getting the message "unable to connect". I've tried gmail, yahoo and other mails. And I cant find where the problem is, please help me.
thanks.

Can you attach netbeans project to this thread (click "Go Advanced" button at the right of "Post Quick Reply" button and add zip file of your project there.)? We can test the project here too.

Note that some email servers only allows secure connection (e.g. gmail) and you might need to enable pop3/smtp for those servers (e.g. for gmail, you need to activate these from your options panel).

You can also try the programs below:

I had tried "Connecting GMail using POP3 connection with SSL" example there before. It should work.

you have to add javamail-1.4 and jaf-1.1
import the mail.jar file to the project. it is in javamail, you need to download it,
and import the activation.jar, it is in jaf-1.1
I cant upload javamail and jaf because the size are too big.
the only problem is I can not connet via the connection dialog .
I've configured gmail pop settings.
please help me to solve connection problem.

Hi again,

Sorry for delay. I checked the code and run it. I think the problem is that this program is using POP3 and gmail and others require POP3 over SSH.

If you have a gmail account, i recommend you to try the example below first. If it works for you then you can replace the javamail functionality in the client GUI easily.

Can you share the solution? Is the problem SSL related?

yes, the solution is connecting gmail pop3 server over SSL. And also you have to create smtps connection to send a mail.Smtp is using SSL too. I added 2 connection codes to the project and now it works. Thanks again..
