java.lang.NoClassDefFoundError: javax/mail/MessagingException unsolved

Question

I'm trying to add the javax.mail jar to my classpath but I get this error:

java.lang.NoClassDefFoundError: javax/mail/MessagingException
    at java.lang.Class.getDeclaredConstructors0(Native Method)
    at java.lang.Class.privateGetDeclaredConstructors(Class.java:2663)
    at java.lang.Class.getDeclaredConstructors(Class.java:2012)
    at org.springframework.beans.factory.annotation.

I've readed in other post that it could be fixed adding the dependecy to the pom.xml, so I did it:

pom.xml

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mail</artifactId>
    <version>1.4.3</version>
</dependency>

But still I'm getting the error ..can someone help me with this?

Answer 1

Also with the 1.4.3 version there is no longer an artifact id called mail. If you want to use 1.4.3 you should use this dependency

<dependency>
    <groupId>javax.mail</groupId>
    <artifactId>mailapi</artifactId>
    <version>1.4.3</version>
</dependency>

Answer 2

You should add the jar to the server Tomcat.

1. Open launch configuration

   

2. Add external jar (look for your email jar)
