Javamail extract body part

Question

Hello All,
I am new to javamail api.
The problems, i am encountering are outlined below.
1- First problem which i am encountering is, when i extract the body out of the email, it contains different html tags as well. How can i get rid of these
html tags?
2- Lets say, in my test Gmail account, i had three test emails. Once i read the email body of all three messages and try to
re-run my application, it says, there are no emails in the Gmail inbox. I am unable to understand this concept, so please
help me.
3- Thirdly the disposition is always returned as null, in every case. Why is that?
My code is given below.

Answer 1

1- First problem which i am encountering is, when i extract the body out of the email, it contains different html tags as well. How can i get rid of these
html tags?By processing the string to remove the tags. If you don't want to have to parse the html yourself,
you can search the web for one of the many html parsing Java libraries. (This isn't really a JavaMail problem.)
2- Lets say, in my test Gmail account, i had three test emails. Once i read the email body of all three messages and try to
re-run my application, it says, there are no emails in the Gmail inbox. I am unable to understand this concept, so please
help me.IMAP or POP3? What are your Gmail settings? Did you read the JavaMail FAQ about connecting to Gmail?
3- Thirdly the disposition is always returned as null, in every case. Why is that?The disposition is optional, so perhaps the sender didn't include it. Or perhaps the server isn't properly
reporting it to the client. Post the protocol trace when accessing a message with no disposition and
post the corresponding MIME content of the message.
