How to run folderlist.java with javax.mail-1.5.4.jar with Gmail using SSL POP3 protocol? I have a valid Gmail email account.

folderlist.java in javamail-samples.zip can be used to retrieve mail folder information from Gmail mail server using SSL POP3 protocol. Here is an execution session of folderlist.java with javax.mail-1.5.4.jar:

fyicenter>cd \local\javamail-1.5.4\javamail-samples

local\javamail-1.5.4\javamail-samples>java -version
java version "1.8.0_45"

local\javamail-1.5.4\javamail-samples>javac -cp .;..\javax.mail-1.5.4.jar
   folderlist.java

local\javamail-1.5.4\javamail-samples>java -cp .;..\javax.mail-1.5.4.jar
   folderlist -D -L pop3s://john:password@pop.gmail.com

The output shows that:

• The javax.mail-1.5.4.jar contains JavaMail API classes like javax.mail.Service.
• The javax.mail-1.5.4.jar contains POP3 implementation classes like com.sun.mail.pop3.POP3Store.protocolConnect.
• JavaMail 1.5.4 supports SSL POP3 protocol.
• pop.gmail.com server supports SSL POP3 protocol on port 995.
• The authentication failed exception is expected, because the account name and password are invalid. If you provide your real gmail account name and password, you will get correct result.
