Error Compiling With java.mail.Session class

Hi,
The Java compiler issues an error message (below) during compilation of the following line:
Session session = Session.getDefaultInstance( fMailServerConfig, null );
The error message is:
bad class file: c:\j2ee_sdk\lib\j2ee.jar(javax/mail/Session.class)
class file has wrong version 48.0, should be 47.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
javax.mail.Session session = javax.mail.Session.getDefaultInstance( fMailServerConfig, null );
I have tried switching between JDKs by changing the JAVA_HOME environment variable between JDKs 1.3.x to 1.4.x to 1.5.x and also to the JDK installed with the 2005 Q1 J2EE installation that I am using.
Any ideas on how to resolve this problem? And help would be GREATLY appreciated.
Thanks!!!
Stuart Hoffman

in Session session = Session.getDefaultInstance( fMailServerConfig, null ); pass the object of properties class instead of mailServerconfig
now your problem are solved

Only 274 mails are coming when using pop3 with java mail

Only 274 mails are coming from GMAIL when using pop3 with java mail. but there are more than 3000 mails.
I'm not getting the reason, code is given below:

Is it possible that GMail only allows access to untagged emails via POP3? Or only to emails from the last x days?
POP3 is the older email retrieval protocol (IMAP4 is the more current one) and only has very limited support for folders (or anything but a single inbox, really). It's quite common that POP3 only allows access to a subset of all emails stored by a provider.

Error: invalid file 'java/lang/Object.class' (wrong version: 48, expected 4

hi all
ive installed jdk1.4.1 from jdk1.3 .
When i try to compile a java file i get this error.
Error: invalid file 'java/lang/Object.class' (wrong version: 48, expected 45)
anyone has any idea abt this.
im stuck :( pls help.

Did you uninstall 1.3 completely? Completely in the sense both jdk and jre.
You may get this error if you use javac of one version and the rt.jar of another version.

How to use a progress bar with java mail?

Hi, i'm new here.
I want if someone can recommend me how to show a progress bar with java mail.
Because, i send a message but the screen freeze, and the progress bar never appear, after the send progress finish.
Thanks

So why would the code we post be any different than the code in the tutorial? Why do you think our code would be easier to understand? The tutorial contains explanations about the code.
Did you download the code and execute it? Did it work? Then customize the code to suit your situation. We can't give you the code because we don't know exactly what you are attempting to do. We don't know how you have changed to demo code so that it no longer works. Its up to you to compare your code with the demo code to see what the difference is.

TLS 1.2 with Java Mail

How can I enforce the communication on TLS 1.2 with Java Mail API?
I try to set TLSv1.2 is SSLContext but the communication always takes place on TLSv1.
Please suggest.

Are you setting a new default SSLContext?
By default, JavaMail will use the default SSLSocketFactory, which (I believe) by default will use the default SSLContext.
You can also set the property mail.<protocol>.ssl.protocols to the protocol you want to be used,
which will be passed to the SSLSocket.setEnabledProtocols method.

Issue with JAVA Mail API

Hi
We have a requirement to create a custom e mail. For the same I am trying to use Java Mail API.I am facing an issue with the following code:
session session1 = session.getInstance(properties, null);
System gives an error Sourced file: inline evaluation of: ``Properties props = new Properties(); session session1 = session.getInstance(prop . . . '' : Typed variable declaration : Class: session not found in namespace
Is there some specific API i need to import for session class. Kindly suggest.

Help with compiling with Java 1.3 in Windows 98

Using JDK 1.3 and Windows 98... here is my problem. If I create a class called EventSite.java and another class called eventsite.java (same name, different cases) and then compile them both...I only see the the first class compiled in the directory (they are both being compiled into the same directory).
i.e. I run 'javac EventSite.java' and when I look in the c:\jdk1_3\bin\ directory I see EventSite.class.
I then run 'javac eventsite.java' and when I look in the same directory I only see EventSite.class. Why???????
Where did eventsite.class go?
Note: both .java files compile without error.
Help please.

Yes it is very strange. Both .java files compile clean yet the second one does not seem to create a .class file. If you are using Windows 98 you can do a simple test to see this...
Create a class with a simple method in it.
Save the file as 'Test.java' (capital 'T').
Compile it into a directory (c:\jdk1.3\bin\).
Using Windows Explorer, check the directory and see 'Test.class' exists.
Now go into the code of the same class and just change the name of the class and save as 'test.java' (lower case 't').
Compile it into the same directory (c:\jdk1.3\bin\).
Using Windows Explorer, check the directory and see 'Test.class' still exists, 'test.class' does not.
Note. If you delete 'Test.class' from the directory and then recompile 'test.java', you will then see 'test.class' in the directory.
It's very wierd and it isn't an issue with a particular computer either. I am taking a class in Java currently and everyone in the clas is having this issue...even the professor hasnt seen this before which is why I figured I would ask on here.
Any thoughts???? Thanks

Having Trouble with Java Mail and Servlets

How can I send and receive mails using Java Mail API and Servlets

You should familiarize yourself with the JavaMail API and the servlet API--this is much too broad a question to properly answer in a forum. The J2EE Tutorial shows how to send a mail message using JavaMail from a session bean, but the technique is similar to what you would use from a servlet:
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Resources5.html#wp82097
I'm sure the JavaMail documentation has an example as well.

Weblogic Java Mail Session

Cannot figure out what's the problem?
I'm trying to send e-mail via Weblogic Mail Session EJB, the code seems pretty right to me, but it's always is throwing an exception.
For SMTP I'm using personal computer SMTP service (Win XP), smtp.host=my IP address, user=domain name.
--- begin ---
javax.mail.SendFailedException: Sending failed; nested exception is: javax.mail.SendFailedException: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay for [email protected] at javax.mail.Transport.send0(Transport.java:219)
--- end ---
Does anyone have an idea what's the glitch?

This looks like a relay problem. Usually, ISPs have mail locked down so that you cannot send from their SMTP server without being logged in through them. They need to verify that you have an account with them and that you are logged on through that account ... usually done by checking to see if you have done a POP login in the last X number of minutes.
Hope this helps.

How to Show images in mail box with java mail??????????

Please help.
Thanks.

On another note, please refrain from posting unnecessary, excessive punctuation. It only clutters up your message, which isn't a good thing. Thanks!
