          I am using Weblogic 5.1 server and used JavaMailAPI.I have
          included mail.jar and activation.jar paths in the CLASSPATH
          variable.
          Can anyone help me figure out where the problem is.
          Thanks for any help.

Make sure you add the following lines in your code:
          // Get system properties
          Properties props = System.getProperties();
          // Setup mail server
          props.put("mail.smtp.host", host);
          // Get session
          Session session = Session.getInstance(props, null);
          If you use any other protocol other than smtp you need to include the corresponding jar file.
          Thanks,
          Kumar.

Javax.mail.NoSuchProviderException: No provider for Address type: rfc822

Use JavaMail 1.2 send Mail Errors:
"javax.mail.NoSuchProviderException: No provider for Address type: rfc822"
Why?
Can you supply a stmp server name?
Thanks.

[skyask],
Honestly, I am not very sure where the JVM is located for the WebLogic 5.1 application server. You probably need to contact your local BEA rep office for support.
The jar file for the JavaMail API is either mail.jar (contains the API libraries) or mailapi.jar (contains the API libraries and all the providers), so I guess if you search the WebLogic directories, you might be able to locate it.
It also depends on the OS platform that you are working on and the WebLogic installation documentation may give a clue or two where the .jar files for optional Java packages are found.

Javax.mail.NoSuchProviderException: No provider for SMTP

whats the meaning of the following exception javax.mail.NoSuchProviderException: No provider for SMTP
can any one help.
thanks and regards.

This exception is thrown when Session attempts to instantiate a Provider (e.g. (com.sun.mail.smtp.SMTPTransport)) that doesn't exist.
Check if the smtp.jar is in the classpath.

Javax.mail.NoSuchProviderException: No provider for ifs1

Similar to the question found in William Troper's thread run on
November 1. We had mail code working fine, changed some
variables to incorporate a migratable build and have now lost
our mail functionality.
We have followed William's advice by renaming all of Sun's Mail
classes in the ~\9ifs\settings\META-INF directory and still no
joy.
Does anyone have any ideas of what is causing a "No provider for
ifs1" error message?
Cheers,
Susan

Hi Scott,
These (among other) items are in my CLASSPATH (printed out at
runtime)

Here is my stack. Also, the code is EXACLTY the same between
what was working and what is now not. Thanks for looking in to

When I use it in the app same class. In the console of the Tomcat server I am getting an exeption javax.mail.NoSuchProviderException : smtp....
Tomcat has also activation.jar; and mail.jar in it's \common\lib directory, I modified the classpath statement in catalina.bat to include the mail.jar, activation.jar and smtp.jar. and I am getting the same error. Does anyone have a suggestion why it is not working in Tomcat 4.1. Please Help !
Thanks

Thanks for answering!
I do have it in the JAVA_HOME\jre\lib\ext directory as well.

Error javax.mail.NoSuchProviderException: pop3

When my application runs within JBuilder everything works fine. But with a native executable I get the following error: javax.mail.NoSuchProviderException: pop3.
The Dependencies property for JavaMail=Include Dependencies. When set to Include All the native executable not even starts.
What is wrong here?
Greetings,
Hans

I had some difficulty looking for a solution to this problem.
All solutions 'beat about the same bush' but I couldnt get any of them to work.
My advice is dont give up- the problem will eventually be resolved.
How I resolved it was to assume, ( rightly) that when working inside JBuilder, it is not using the machine classpath to find library files such as mail.jar, but looking at its own library of jar files to find mail.jar.
I tracked down the JBuilder mail.jar in the /lib dir and copied out all classes beginning with POP... also all non Class files eg proviider and map files , the mailcap file and all files beginning with SUN, and also the Manifest file and placed them in a separate folder on the hard drive.
I then made an application jar definition from my JBuilder application but told it NOT to make a manifest file.I then right clicked on the build file, and selected properties/content and added in all files from the directory that I previously made containing the files mentioned above.
To the Manifest file in that directory I also added the mine Main Class: to tell it where my main class was.
I then re-built the executable jar file.
It worked. Just when I was down to pulling out the last tuft of hair.

[joyrex75],
I suspect that the CLASSPATH settings on the machine that you are using is pointing only to the mail.jar file. If you are setting up the Java runtime environment that includes only the mail.jar file, your runtime environment will not have the mail providers such as the POP3, IMAP or SMTP .jar files.
Point your CLASSPATH to the mailapi.jar file which contains the JavaMail APIs and all the mail protocol providers that SUN supports i.e. POP3, IMAP and SMTP. Try to execute the java command on your JavaMail application and see if throws out the Exception again.

Javax.mail.NoSuchProviderException: No provider for imap

Dear All,
Currently i am running weblogic 5.1 for my javamail Application/WebMail. I have copied mail.jar, activation.jar,pop3.jar,imap.jarmailapi.jar in weblogic\jre1_2\jre\lib\ext folder. I get "javax.mail.NoSuchProviderException: No provider " exception when i run jsp page.
Balaji

It looks like weblogic 5.1 (atleast the mail.jar) doesn't contain the pop3.jar, I guess. Check whether you can include pop3.jar in ur classpath..

JavaMailSenderImpl - NoSuchProviderException: smtp - duplicate in classpath

I have been having an issue a:
NoSuchProviderException: smtp
Exception. I have read all of the forums saying its either missing 'smtp.jar' or 'activation.jar' in the classpath, but that is not the case for me. I have the full mail.jar (1.4 from maven) and activation 1.1. The problem is that when the "mail-1.4.jar" jar IS in my classpath, I encounter this exception.
I am assuming that one of the dependent jars contains some file/class that registers the smtp protocol somewhere else, or there is another version of mail somewhere buried in the dependancies, but not 100% sure, and cant find it.
Does anyone know why this could be happening? Or what specific files/classes I can look for that would register the smtp protocol?

Even with mail.debug=true, I dont get more detailed messages - or anymore from javax.mail. The only error is:

Why has there NoSuchProviderException in JAR file?

My program run well in jbuilder IDE, but after i make the project into JAR file, I meet the exception:
javax.mail.NoSuchProviderException: No provider for smtp
i set the classpath well, because my other program(.class) sending email well.
who knows what should i do?

Please kindly send the solution for this problem.
My program runs well since Web Gain-Visual Cafee in a windows 2000 machine, but when I make the project (a setup file) install it in a Windows 98 machine, it gives NoSuchProviderException No Provider for rfc822.

NoSuchProviderException what is it?

I'm trying to create an application (J2SE not J2EE - or Client Programs Like OpenOffice.org Writer) that sends some information to
an email, for example [email protected], from ([email protected]) by using smtp (mydomain.com)
but during sending the message it gives me this exception: javax.mail.NoSuchProviderException: No provider for Address type: rfc822
here is the code...
import javax.mail.*;
import javax.mail.internet.*;
import javax.mail.Transport;
import java.util.*;
import java.io.*;
public class SendMail{
     public void postMail( String recipients[ ], String subject, String message, String from) throws MessagingException{
          boolean debug = false;
          Properties props = new Properties();
          props.put("mail.smtp.host", "mydomain.com");
          props.put("mail.smtp.port", "25");
          Session session = Session.getDefaultInstance(props, null);
          session.setDebug(debug);
          MimeMessage msg = new MimeMessage(session);
          InternetAddress addressFrom = new InternetAddress(from);
          msg.setFrom(addressFrom);
          InternetAddress[] addressTo = new InternetAddress[recipients.length];
          for (int i = 0; i < recipients.length; i++)     {
               addressTo[i] = new InternetAddress(recipients);
          msg.setRecipients(Message.RecipientType.TO, addressTo);
          msg.addHeader("MyHeaderName", "myHeaderValue");
          msg.setSubject(subject);
          msg.setContent(message, "text/plain");
          System.out.println("before sending");
          Transport.send(msg);
     public static void main(String args[]) throws MessagingException{
          SendMail o = new SendMail();
          for(int i = 0; i<100; i++){
               String to[]={"[email protected]"};
               String from="[email protected]";
               String msg="Message";
               String sub="Sub";
               System.out.println("sending... : "+i);
               o.postMail(to,sub,msg,from);
               System.out.println("sending over...");

Please Help.
Thanks in advance

String strHost = "smtp.gmail.com";...
          trans = session.getTransport(strHost);You figured out that the above line is the line that caused the
problem, right?
And then after reading the javadocs that say:
Get a Transport object that implements the specified protocol.
You just couldn't figure out why "smtp.gmail.com" was not a valid
protocol, right?
The protocol name is "smtp". "smtp.gmail.com" is a host name.

Es1javax.mail.NoSuchProviderException: No provider for pop3 ?

What is wrong with this code?Do i need to specify a Provider? Where and when?
String host = ...;
String username = ...;
String password = ...;
// Create empty properties
Properties props = new Properties();
// Get session
Session ses = Session.getDefaultInstance(props, null);
// Get the store
Store store = ses.getStore("pop3");
store.connect(host, username, password);
// Get folder
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
// Get directory
Message message[] = folder.getMessages();
for (int i=0, n=message.length; i<n; i++) {
System.out.println(i + ": " + message.getFrom()[0]
+ "\t" + message[i].getSubject());
// Close connection
folder.close(false);
store.close();
Thank you all
Dena

[denapuerta],
The exception that you are getting may mean that the java runtime environment that you are running your class file code on does not seem to have the JavaMail .jar files installed correctly. The JavaMail API packages are optional packages and must be downloaded and added to the J2SE runtime environment before such an application can run successfully.
From the exception message, looks like either the pop3.jar file or the mailapi.jar (which contains all the JavaMail API and provider library files) is missing from the CLASSPATH of the JRE or not installed onto the <JRE install directory>/jre/lib/ext directory.
What is wrong with this code?Do i need to specify a
Provider? Where and when?I assume you obtained the code from the jGuru tutorial on JavaMail (which is a good tutorial to start off with). I have tested the code before and it works perfectly fine.
String host = ...;
String username = ...;
String password = ...;
// Create empty properties
Properties props = new Properties();
// Get session
Session ses = Session.getDefaultInstance(props, null);
// Get the store
Store store = ses.getStore("pop3");
store.connect(host, username, password);
// Get folder
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
// Get directory
Message message[] = folder.getMessages();
for (int i=0, n=message.length; i<n; i++) {
System.out.println(i + ": " +
+ message.getFrom()[0]
+ "\t" + message[i].getSubject());
// Close connection
folder.close(false);
store.close();
Thank you all
Dena
You might also want to check the username/password and hostname string entries to see if you are really connecting to the POP3 mail server correctly.

How to strore keys in KeyStores..of JCE Api..

Hi ,
i'm trying to implement a program mySignature that creates and verifies digital signatures using Java Cryptography Extension.
I am using the DSA Algorithm for encryption.
Now the problem is once i create the private keys and public keys i am not able to store them to the KeyStore.
here is the code I wrote
package my.security.test;
import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;

I get an error while i try to store the key on to the KeyStore, if I comment out these lines of code the program runs without any probs.
Can any one help me with this issue, i'ld be thank full to them

We use 'PDDocCreateWordFinder' , 'PDWordFinderEnumWords' to extract the text from Adobe Reader document through Code, Not tool.
But, by using these APIs, I can't see any difference in 'new line/row' or 'paragraph' if exists in PDF doc.
I need such API which can give the exact format of Adobe Reader doc according to the content exists in that PDF doc.
Thanks!
