javax.mail.NoSuchProviderException: Provider class does not have a constructor(Session, URLName)

Exception: javax.mail.NoSuchProviderException: Provider class does not have a constructor(Session, URLName)

SOLUTION: javax.mail/1.6.2.jar file is not included in the WebApp.war file which is deployed in the server. If not available then after creating the war build. In war file, lib folder download javax.mail.jar and add it

Different Ways of solution:

• stackpost Removing the duplicate javax.mail classes from the webapp fixes the problem.
• POST: I read some threads in several forums where people had encountered the same when there were multiple versions of java mail available through different classloaders.

Fail LOG:

DEBUG: getProvider() returning provider protocol=imap; type=javax.mail.Provider$Type@6accb714; class=com.sun.mail.imap.IMAPStore; vendor=Oracle
