[SOLVED] Extracting PST file containing mail as an attachment of PSTMessage

Extracting PST file containing mail as an attachment of PSTMessage

I'm trying to extract PST files using java-libpst-0.8.1 , following https://code.google.com/p/java-libpst/

In my sample pst file, there are several mails. In one of the mail of that pst file, the attachment is also a mail. While parsing that PSTMessage, it's not able to fetch even, attachment's name. Please find the sample code.

 PSTMessage email;
 PSTAttachment attach;
 email = (PSTMessage) folder.getNextChild();
 while (email != null) {
    try {
        numberOfAttachments = email.getNumberOfAttachments();
        if (numberOfAttachments > 0) {
           for (int x = 0; x < numberOfAttachments; x++) {
               attach = email.getAttachment(x);
               try {
                    attachmentName = attach.getLongFilename();

Though the program is giving the exact count of the mail's attachments. But it's not able to provide, the attached mail's name or extracting it's content. Can anyone suggest a way what should I do?

Solution

Finally, I'm able to read the mail which is an attachment of a mail. There is a method getEmbeddedPSTMessage() in PSTAttachment class. First I need to check whether it's a normal attachment or a mail. For that we need to refer getAttachMethod(). If it returns 5 it's an embedded message. For details, please check out the documentation of PSTAttachment.

if (attach.getAttachMethod() == 5) {
     PSTMessage attachEmail = attach.getEmbeddedPSTMessage();
}
