Get Emails through IMap

Good Afternoon,

I'm needing to connect to a imap account to get all incoming messages, but when I try to use the ImapReceiver I can check the total messages in the account, but not get the messages.

Following example used.

1th

Code:

---

ImapMailReceiver receiver = new ImapMailReceiver("imaps://xxxx:yyyy@imap.gmail.com:993/INBOX");
receiver.setShouldMarkMessagesAsRead(true);
receiver.setShouldDeleteMessages(true);

// When i call this method throw new exception  "NullPointerException"
Message[] a = receiver.receive();

Exception:

Code:

---

You need to show the exception (full stack trace).

I suggest you change your gmail password - you had it in clear text above - I have edited it out.

Looks like you hid it when you posted the same question on StackExchange.

Sorry for that error,

I edited the original post to insert the exception.

Thanks!

Why are you trying to use the ImapMailReceiver programmaticially that way (instead of configuring it normally)?

There is a lot of stuff that the Spring Framework does to wire up and initialize these components. For example, afterPropertiesSet() changes the open mode for the inbox from READ_ONLY to READ_WRITE (which is the cause of your problem).

So, either wire up the receiver using a Spring application context (XML or @Bean), or be sure to call afterPropertiesSet() after you (er) set the properties.

Dear Gary Russell,

I'm trying to understand before i implement in the project, but i'll check what you said for check if this error will happen again.

Thanks for your help.
