Import javax mail error - Исправление ошибок и поиск оптимальных решений проблем

When I compile a simple code that has the following 2 import statements:

import javax.mail.*

import javax.mail.internet.*

I get the following message:

package javax.mail does not exist

package javax.mail.internet does not exist

Why do I get this error?

Here is the code I have:

import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;

class tester {
 public static void main(String args[]) {
   Properties props = new Properties();
   props.put("mail.smtp.com" , "smtp.gmail.com");
   Session session  = Session.getDefaultInstance( props , null);
   String to = "me@gmail.com";
   String from = "from@gmail.com";
   String subject = "Testing...";
   Message msg = new MimeMessage(session);
    try {
      msg.setFrom(new InternetAddress(from));
      msg.setRecipient(Message.RecipientType.TO , new InternetAddress(to));
      msg.setSubject(subject);
      msg.setText("Working fine..!");
    }  catch(Exception exc) {
       }
 }
}

You need to download the JavaMail API, and put the relevant jar files in your classpath.

If using maven, just add to your pom.xml:

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.5.0-b01</version>
</dependency>

Of course, you need to check the current version.

Download javax.mail.jar and add it to your project using the following steps:

Extract the mail.jar file
Right click the project node (JavaMail), click Properties to change properties of the project
Now go to Libraries Tab
Click on Add JAR/Folder Button. A window opens up.
Browse to the location where you have unzipped your Mail.jar
Press ok
Compile your program to check whether the JAR files have been successfully included

You need the javax.mail.jar library.
Download it from the Java EE JavaMail GitHub page and add it to your IntelliJ project:

Download javax.mail.jar
Navigate to File > Project Structure...
Go to the Libraries tab
Click on the + button (Add New Project Library)
Browse to the javax.mail.jar file
Click OK to apply the changes

For anyone still looking to use the aforementioned IMAP library but need to use gradle, simply add this line to your modules gradle file (not the main gradle file)

compile group: 'javax.mail', name: 'mail', version: '1.4.1'

The links to download the .jar file were dead for me, so had to go with an alternate route.

Hope this helps

It might be that you do not have the necessary .jar files that give you access to the Java Mail API. These can be downloaded from here.

You need the javax.mail.jar library. Download it from the https://www.oracle.com/java/technologies/javamail-releases.html and add it to your Eclipse project:

If you are using <module-info.java> then,

Right-click on Project, go to Build Path -> Configure Build Path -> Libraries -> ModulePath -> Add External Jars.
Browse to the javax.mail.jar file
Click «Apply and Close».

Under module-info.java, add this:

module TestApp {
    **requires mail;**
}

you have to set the classpath of your mail.jar and activation.jar file like that:

open the command prompt:

c:user>set classpath=%classpath%;d:jarfilesmail.jar;d:jarfilesactivation.jar;.;

and if u don’t have the both file then please download them here

Download the Java mail jars.
Extract the downloaded file.
Copy the «.jar» file and paste it into ProjectNameWebContentWEB-INFlib folder
Right click on the Project and go to Properties
Select Java Build Path and then select Libraries
Add JARs…
Select the .jar file from ProjectNameWebContentWEB-INFlib and click OK

that’s all

Had the same issue. Obviously these .jars were included with Java <= v8.x out of the box, but are not anymore. Thus one has to separately download them and place them in the appropriate classpath as highlighted by several folks above. I understand that the new Java is modularized and thus potentially more light-weight (which is certainly a good thing, since the old setup was a monster). On the other hand this — as we can see — breaks lots of old build setups. Since the time to fix these isn’t chargeable to Oracle I guess this made their decision easy…

I just resolved this for myself, so hope this helps. My project runs on GlassFish 4, Eclipse MARS, with JDK 1.8 and JavaEE 7.

Firstly, you can find javax.mail.jar in the extracted glassfish folder: glassfish4->glassfish->modules

Next, in Eclipse, Right Click on your project in the explorer and navigate the following: Properties->Java Build Path->Libraries->Add External JARs-> Go to the aforementioned folder to add javax.mail.jar

I am developing an application which the application will automatically send out an email to user informing user the current phone status once the phone is stolen or lost. But I faced problem in importing javax.mail «The import javax.mail cannot be resolved». What should I do? Thanks…

I have been using eclipse to code and test my software on Windows. When I copy the code to Ubuntu, I cannot compile the code as it cannot find the Javax files to import. I know I need to add the classpath where the jar file is located. My question is where or what name is the jar file? Any suggestions much appreciated.

Compile statement
javac eMail.java

Java code
import javax.mail.Folder;
import javax.mail.Message;

Error
import javax.mail.Folder;
^
eMail.java:7: error: package javax.mail does not exist

for each import statement.

As far as I know the mail library has always been an external download. It’s currently located on github at https://github.com/javaee/javamail/releases. Download it and add it to your classpath in Eclipse.

If you developed on Windows first you have to take into account what Build Paths your project had in there. I think you could take two approach to solve this:

1-Screnshot/Write down build path and project preferences from Windows and try to replicate that on your Linux dev machine, see eclipse documentation

2-Export your Windows projects and then import them on Linux, please see this StackOVerflow question

Also I think you shouldn’t asking here for locations of jar files from your projects, If you are the developer you should know where the files needed by your projects are(Just IMHO, don’t take this as a personal attack please ;))
