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.

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.

I ended up resolving this by cut/paste the class inside the same namespace and physical .cs file. – Brian Garr just now edit
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;
}
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.
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?
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();
}
}
}
