While Mail body being received, how to fetch the Image from multipart body - ckeditor

My application actually has mail send / receive functionalities to handle.
While receiving the mail, i am unable to view the image which is an inline image being sent from outlook.
Can some one help me how can i catch the image and make available always.
I have java code like below,
try (InputStream stream = new ByteArrayInputStream(Base64
.getMimeDecoder().decode(mail))) {
MimeMessage message = new MimeMessage(null, stream);
Object messageContent = message.getContent();
if (messageContent instanceof String) {
body = (String) messageContent;
} else if (messageContent instanceof MimeMultipart) {
content = (MimeMultipart) messageContent;
for (int i = 0; i < content.getCount(); i++) {
BodyPart bodyPart = content.getBodyPart(i);
String disposition = bodyPart.getDisposition();
if (disposition == null
|| disposition
.equalsIgnoreCase(Part.INLINE)) {
Object object = bodyPart.getContent();
if (object instanceof String) {
body = object.toString();
} else if (object instanceof MimeMultipart) {
MimeMultipart mimeMultipart = (MimeMultipart) object;
String plainBody = null;
String htmlBody = null;
for (int j = 0; j < mimeMultipart.getCount(); j++) {
BodyPart multipartBodyPart = mimeMultipart
.getBodyPart(j);
String multipartDisposition = multipartBodyPart
.getDisposition();
String multipartContentType = multipartBodyPart
.getContentType();
if (multipartDisposition == null
&& multipartContentType != null) {
if (multipartContentType
.contains(MediaType.TEXT_HTML)) {
htmlBody = multipartBodyPart
.getContent().toString();
} else if (multipartContentType
.contains(MediaType.TEXT_PLAIN)) {
plainBody = multipartBodyPart
.getContent().toString();
}
}
}
if (htmlBody != null) {
body = htmlBody;
} else {
body = plainBody;
}
}
}
}
}
Client side i am using CKEditor to handle email body data.
Thanks a lot.

i got a solution from the example shared below
https://www.tutorialspoint.com/javamail_api/javamail_api_fetching_emails.htm
But, this example explains, how to find the image in body and store.
I have also done below to replace src
`
Pattern htmltag = Pattern.compile("]src=\"[^>]>(.?)");
Pattern link = Pattern.compile("src=\"[^>]\">");
String s1 = "";
Matcher tagmatch = htmltag.matcher(s1);
List<String> links = new ArrayList<String>();
while (tagmatch.find()) {
Matcher matcher = link.matcher(tagmatch.group());
matcher.find();
String link1 = matcher.group().replaceFirst("src=\"", "")
.replaceFirst("\">", "")
.replaceFirst("\"[\\s]?target=\"[a-zA-Z_0-9]*", "");
links.add(link1);
s1 = s1.replaceAll(link1, "C:\\//Initiatives_KM\\//image.jpg");
}
`
And on top of this, i gonna do Base64 encoding so that i dont require store in file system.
encodedfileString = Base64.getEncoder().encodeToString(bArray);
With all these i can conclude to say, i got solution for my issue. Thank you.

Can't find way to debug Internal Server Error (500) caused by new class

I've read a lot of the postings about 500 errors because of the channel emulator, but this is not the case here. I took the standard bot template, which works just fine with the emulator, and replaced it with
ConnectorClient connector = new ConnectorClient(new
Uri(activity.ServiceUrl));
// calculate something for us to return
// int length = (activity.Text ?? string.Empty).Length;
string responseText=
***Bot_Application2.SilviaRestClass.GetRestResult(activity.Text);***
So the issue is in executing the GetRestResult method in the SilivaRestClass.
The code itself works, I'm using it in lots of other places, as it basically sets up a simple 1)get an input utterance in text, 2)send to my SILVIA AI server, and 3)get an utterance back routine. I have a feeling it has something to do with either private vs public methods, and/or [Serializable], based on what I have read so far. The code (minus the credentials) is below. Many thanks, in advance, for any suggestions to try.

Catch incoming emails and send them to a web service (rather than just to a mail server)

I would like to catch incoming emails and send them a web service (rather than just to a mail server).
--
After some searching I found a way of getting new emails via polling - see below: This may be of some help to others. Is there a way to receive messages by SMTP? Perhaps by ISAPI ???
using Limilabs.Mail;
using Limilabs.Client.IMAP;
public ActionResult checkIMAPmail()
{
string rval = "not a sausage";
using (Imap imap = new Imap())
{
imap.Connect(<mail server>);
imap.Login(<username>, <password>);
imap.SelectInbox();
List<long> uids = imap.Search(Flag.Unseen);
foreach (long uid in uids)
{
byte[] ourBytes = imap.GetMessageByUID(uid);
IMail email = new MailBuilder().CreateFromEml(ourBytes);
rval = email.Subject + " [" + email.From + "][" + email.Text + "]";
}
imap.Close();
}
return Content(rval, "text/html");
}
See also http://stackoverflow.com/questions/670183/accessing-imap-in-c-sharp
for other IMAP packages, although note the change to using byte[], above.
Given that Limilabs.Mail is a paid service, I finally used MailKit:
using MailKit;
public int checkIMAPmail()
{
int numEmails = 0;
try {
using (var client = new MailKit.Net.Imap.ImapClient())
{
client.ServerCertificateValidationCallback = (s, c, h, e) => true;
client.Connect(ourSmtpClient);
// disable the XOAUTH2 authentication mechanism.
client.AuthenticationMechanisms.Remove("XOAUTH2");
client.Authenticate(ourSmtpAdminUser, ourSmtpAdminUserPwd);
// The Inbox folder is always available on all IMAP servers...
var inboxFolder = client.Inbox;
var savedFolder = client.GetFolder("saved");
inboxFolder.Open(FolderAccess.ReadWrite);
for (int ii = 0; ii < inboxFolder.Count; ii++)
{
var query = MailKit.Search.SearchQuery.NotSeen;
foreach (var uid in inboxFolder.Search(query))
{
var thisMsg = inboxFolder.GetMessage(uid);
string thisDate = notNullString(thisMsg.Date);
string thisSubject = notNullString( thisMsg.Subject);
string thisBody = notNullString(thisMsg.GetTextBody(0)); // plain text
string thisFromName = "";
string thisFromEmail = "";
if ( thisMsg.From != null)
{
// just get the first
foreach( var mb in thisMsg.From.Mailboxes)
{
thisFromName = notNullString( mb.Name);
thisFromEmail = notNullString( mb.Address);
break;
}
}
numEmails += 1;
// move email to saved
inboxFolder.MoveTo(uid, savedFolder);
}
}
client.Disconnect(true);
}
}
catch (Exception exc)
{
log2file("checkIMAPmail Error: " + exc.ToString());
}
return numEmails;
}

Process gets stuck in oSession.Logoff()

Pstcreation works properly with outlook installed.
Now, I am trying to create a pst file with standalone version of MAPI . But my process is stuck in oSession.LogOff(). Further if a comment that oSession.LogOff() line and subsequently call the CreatePstWithRedemption function to create an other pst, the process gets stuck in oSession.LogonPstStore
private bool CreatePstWithRedemption(EmailJTableArgs objJTablArgs, EmailFilterArgs objFilterArgs,
EmailExportRequestParams emailExportRequestParams)
{
RDOSession oSession = null;
IRDOStore store = null;
RDOFolder fFOlder = null;
RDOFolder childFolder = null;
IRDOItems folderItems = null;
var pstCreationStatus = false;
try
{
oSession = new RDOSession();
store = oSession.LogonPstStore(_fileName, 1, "PST");
var folderName = Path.GetFileNameWithoutExtension(_fileName);
if (store != null)
{
fFOlder = store.IPMRootFolder;
foreach (RDOFolder folder in fFOlder.Folders)
{
folder.Delete();
}
childFolder = fFOlder.Folders.Add(folderName, Type.Missing);
folderItems = childFolder.Items;
var resultOfGetEmails = new ResultGetEmails();
resultOfGetEmails.TotalCount = -1;
do
{
var journalEmails = GetEmailList(objFilterArgs, objJTablArgs, emailExportRequestParams,
resultOfGetEmails);
for (var i = 0; i < journalEmails.Count; i++)
{
IRDOMail mail = null;
try
{
mail = folderItems.Add(rdoItemType.olMailItem);
// populate mail fields
mail.Sent = true;
mail.Save();
}
finally
{
if (mail != null)
Marshal.ReleaseComObject(mail);
}
}
resultOfGetEmails.TotalCount -= BatchSize;
objJTablArgs.PageStartIndex += BatchSize;
} while (resultOfGetEmails.TotalCount > 0);
pstCreationStatus = true;
}
}
finally
{
// Do cleanup
if (oSession != null && oSession.LoggedOn)
{
try
{
oSession.Logoff();
Marshal.ReleaseComObject(oSession);
}
catch
{
}
}
}
return pstCreationStatus;
}
Note: The same thing works well when run in an environment where outlook is installed.

j2me midlet chinese character display message garbled

My J2ME midlet could retrieves message in Chinese character from a PHP server but it's garbled. The server basically returns the response string and by detecting the first 2 characters. AA = good, anything else indicates error of which the message is to be passed to the calling function for display

On the PHP server, I have set the header to UTF-8 encoding
<?php header("Content-Type:text/plain; charset=utf-8"); ?>
What could possibly be wrong?
I found that this user has the same problem and it's been answered
Reading UTF8 strings from a server through http using MIDP. Kudos to the answer.
I basically edited my MIDP code from
// is = http.openDataInputStream();
// int length = (int) http.getLength();
// if (length != -1)
// {
// // Read data in one chunk
// byte serverData[] = new byte[length];
// is.read(serverData);
// str = new String(serverData);
// }
// else // Length not available...
// {
// ByteArrayOutputStream bStrm = new ByteArrayOutputStream();
// int ch;
// while ((ch = is.read()) != -1)
// bStrm.write(ch);
//
// str = new String(bStrm.toByteArray());
// bStrm.close();
// }
to
Reader r = new InputStreamReader(http.openInputStream(), "UTF-8");
int ch;
while((ch = r.read()) != -1)
str = str + (char)ch;
just wondering though why does reading bytes messes up the UTF-8 characters?

Issue in reading google text document

I could get the handle to the google text doc i needed. I am now stuck at how to read the contents.
My code looks like:
GoogleOAuthParameters oauthParameters = new GoogleOAuthParameters();
oauthParameters.setOAuthConsumerKey(Constants.CONSUMER_KEY);
oauthParameters.setOAuthConsumerSecret(Constants.CONSUMER_SECRET);
oauthParameters.setOAuthToken(Constants.ACCESS_TOKEN);
oauthParameters.setOAuthTokenSecret(Constants.ACCESS_TOKEN_SECRET);
DocsService client = new DocsService("sakshum-YourAppName-v1");
client.setOAuthCredentials(oauthParameters, new OAuthHmacSha1Signer());
URL feedUrl = new URL("https://docs.google.com/feeds/default/private/full/");
DocumentQuery dquery = new DocumentQuery(feedUrl);
dquery.setTitleQuery("blood_donor_verification_template_dev");
dquery.setTitleExact(true);
dquery.setMaxResults(10);
DocumentListFeed resultFeed = client.getFeed(dquery, DocumentListFeed.class);
System.out.println("feed size:" + resultFeed.getEntries().size());
String emailBody = "";
for (DocumentListEntry entry : resultFeed.getEntries()) {
System.out.println(entry.getPlainTextContent());
emailBody = entry.getPlainTextContent();
}
Plz note that entry.getPlainTextContent() does not work and throws object not TextContent type exception
finally i solved it as:
for (DocumentListEntry entry : resultFeed.getEntries()) {
String docId = entry.getDocId();
String docType = entry.getType();
URL exportUrl =
new URL("https://docs.google.com/feeds/download/" + docType
+ "s/Export?docID=" + docId + "&exportFormat=html");
MediaContent mc = new MediaContent();
mc.setUri(exportUrl.toString());
MediaSource ms = client.getMedia(mc);
InputStream inStream = null;
try {
inStream = ms.getInputStream();
int c;
while ((c = inStream.read()) != -1) {
emailBody.append((char)c);
}
} finally {
if (inStream != null) {
inStream.close();
}
}
}
