I na project I want to use the EmailBean written by Tony McGuckin, IBM
https://openntf.org/XSnippets.nsf/snippet.xsp?id=emailbean-send-dominodocument-html-emails-cw-embedded-images-attachments-custom-headerfooter
However I get an error message when I want to loop through a list of people I want to address:
for (String person : persons) {
EmailBean emailBean = new EmailBean();
emailBean.setSendTo(person);
emailBean.setSubject("You have been mentioned");
emailBean.setSenderEmail("pk#mail.com");
emailBean.setSenderName("PK's app");
Document mail = null;
mail = db.createDocument();
> emailBean.setDocument( mail);
emailBean.setFieldName("Body");
emailBean.setBannerHTML("<p>You have been mentioned in a discussion on PK's App:</p>");
emailBean.setFooterHTML("<p>Kind regards,<br/>PK App<br/></p>");
emailBean.send();
}
The error message I get resides at the > line:
The method setDocument(DominoDocument) in the type EmailBean is not applicable for the arguments (Document) Comment.java comments.nsf/Code/Java/org/quintessens/comments line 98 Java Problem
I have tried to cast the Document as a DominoDocument but then I get an error at line
emailBean.send();
What should I change?
Your mail variable is a Document object. You need to wrap it into a DominoDocument object (the object used as Domino Document datasource)
after your line :
mail = db.createDocument();
add :
DominoDocument wrappedMail = DominoDocument.wrap(db.getFilePath(), mail, null, null, false, null, null);
then use it in your email bean :
emailBean.setDocument( wrappedMail );
But you will have to set something in the "body" field of your document created with this line :
mail = db.createDocument();
and before wrapping it, because the content of the mail you'll send is taken from this field.
But if you want to send "simple" content, use the class from Ulrich Krause in his comment of the XSnippet page which still give you the possibility to add the content of a field to the email but also let you add "simple" content.
Then remove the following lines in your original code :
Document mail = null;
mail = db.createDocument();
emailBean.setDocument( mail);
emailBean.setFieldName("Body");
And use this instead :
emailBean.addHtml("this is my mail content");
You can call this as many times as needed
To get the DominoDocument from a Document, a typical (DominoDocument) will not work.
You need to call the wrap method of the DominoDocument.
See the API, http://public.dhe.ibm.com/software/dw/lotus/Domino-Designer/JavaDocs/DesignerAPIs/com/ibm/xsp/model/domino/wrapped/DominoDocument.html#wrap(java.lang.String, lotus.domino.Document, java.lang.String, java.lang.String, boolean, java.lang.String, java.lang.String)

I work on university project in java. I have to download attachments from new emails using GMAIL API.
I successfully connected to gmail account using OAuth 2.0 authorization.
private static final List<String> SCOPES = Collections.singletonList(GmailScopes.GMAIL_READONLY);
I tried to get unseen mails using
ListMessagesResponse listMessageResponse = service.users().messages().list(user).setQ("is:unseen").execute();
listMessageResponse is not null but when I call method .getResultSizeEstimate() it returns 0
also I tried to convert listMessageResponse to List < Message > (I guess this is more usable) using
List<Message> list = listMessageResponse.getMessages();
But list launches NullPointerException
Then tried to get each attachment with
for(Message m : list) {
List<MessagePart> part = m.getPayload().getParts();
for(MessagePart p: part) {
if(p.getFilename()!=null && p.getFilename().length()>0) {
System.out.println(p.getFilename()); // Just to check attachment filename
}
}
}
Is my approach correct (if not how to fix it) and how should I download those attachments.
EDIT 1:
Fixed q parameter, I mistakenly wrote is:unseen instead of is:unread.
Now app reaches unread mails successfully.
(For example there was two unread mails and both successfully reached, I can get theirs IDs easy).
Now this part trows NullPointerException
List<MessagePart> part = m.getPayload().getParts();
Both messages have attachments and m is not null (I get ID with .getID())
Any ideas how to overcome this and download attachment?
EDIT 2:
Attachments Downloading part
for(MessagePart p : parts) {
if ((p.getFilename() != null && p.getFilename().length() > 0)) {
String filename = p.getFilename();
String attId = p.getBody().getAttachmentId();
MessagePartBody attachPart;
FileOutputStream fileOutFile = null;
try {
attachPart = service.users().messages().attachments().get("me", p.getPartId(), attId).execute();
byte[] fileByteArray = Base64.decodeBase64(attachPart.getData());
fileOutFile = new FileOutputStream(filename); // Or any other dir
fileOutFile.write(fileByteArray);
fileOutFile.close();
}catch (IOException e) {
System.out.println("IO Exception processing attachment: " + filename);
} finally {
if (fileOutFile != null) {
try {
fileOutFile.close();
} catch (IOException e) {
// probably doesn't matter
}
}
}
}
}
Downloading working like charm, tested app with different type of emails.
Only thing left is to change label of unread message (that was reached by app) to read. Any tips how to do it?
And one tiny question:
I want this app to fetch mails on every 10 minutes using TimerTask abstract class. Is there need for manual "closing" of connection with gmail or that's done automatically after run() method iteration ends?
#Override
public void run(){
// Some fancy code
service.close(); // Something like that if even exists
}
I don't think ListMessagesResponse ever becomes null. Even if there are no messages that match your query, at least resultSizeEstimate will get populated in the resulting response: see Users.messages: list > Response.
I think you are using the correct approach, just that there is no message that matches your query. Actually, I never saw is:unseen before. Did you mean is:unread instead?
Update:
When using Users.messages: list only the id and the threadId of each message is populated, so you cannot access the message payload. In order to get the full message resource, you have to use Users.messages: get instead, as you can see in the referenced link:
Note that each message resource contains only an id and a threadId. Additional message details can be fetched using the messages.get method.
So in this case, after getting the list of messages, you have to iterate through the list, and do the following for each message in the list:
Get the message id via m.getId().
Once you have retrieved the message id, use it to call Gmail.Users.Messages.Get and get the full message resource. The retrieved message should have all fields populated, including payload, and you should be able to access the corresponding attachments.
Code sample:
List<Message> list = listMessageResponse.getMessages();
for(Message m : list) {
Message message = service.users().messages().get(user, m.getId()).execute();
List<MessagePart> part = message.getPayload().getParts();
// Rest of code
}
Reference:
Class ListMessagesResponse
Users.messages: list > Response
How can I initialize email in my service class without hardcoding(eg : Email to = new Email("1234#gmail.com"). I use the following code to initialize my email but it returns some error. Help me to fix this. I'm using SendGrid API. Here is my service code:
Email to = new Email();
to.setEmail(emailIDTO.getTO()); //emailIDTO is an object of IDTO class
// IDTO class takes the value from the JSON request body and initializes it to the email object
And the relevant IDTO snippet:
public Email getTo(){
return to;
} // method getTo return the mail id of the recipient.
public Email createTo(EmailIDTO emailIDTO){
to.setName(emailIDTO.getName();
to.setEmail(emailIDTO.getEmail());
return null;
}
Error :
setEmail (java.lang.String) in Email cannot be applied to (com.sendgrid.Email)
Your code is failing because your emailIDTO.getTO() method is returning Email object, which you are trying to assign using method that accepts String parameter. The error is pretty self-explanatory in this case.
You can try one of the following:
Option 1 - set object directly from IDTO:
Email to = emailIDTO.getTO();
Option 2 - extract the string value:
Email to = new Email();
to.setEmail(emailIDTO.getTO().getEmail());
Caution - your IDTO.createTo() method returns null, which may have unexpected consequences. Perhaps you wanted to return to?
I want to have a changefeed on one attribute of my object in rethinkdb in the java language.
I tried this:
Cursor curs = r.db("mytestdb").
table("tennis").
get(Constants.WORKING_PROJECT_ID).
getField("time").
changes().
run(conn);
for (Object doc : curs) {
System.out.println(doc);
}
but I get this com.rethinkdb.gen.exc.ReqlQueryLogicError: Cannot convert STRING to SEQUENCE as an Exception.
Im really new to rethinkDB. Can someone help me ?
getField("time") gets particular field value, you can't subscribe on value.
That's what this com.rethinkdb.gen.exc.ReqlQueryLogicError: Cannot convert STRING to SEQUENCE says.
You can filter changes you want to get:
Cursor curs = r.db("mytestdb").
table("tennis").get(Constants.WORKING_PROJECT_ID)
.filter(row -> row.g("new_val").g("time").ne(row.g("old_val").g("time")))
.changes().run(conn);
for (Object doc : curs) {
}
I am using open graph library to fetch the metadata from url.
I am getting the title and description from url link which follow og tag rules. How to get metadata from url link which don't follow og tag.
my simple code :
OpenGraph data = new OpenGraph(url, true);
response.setDescription(data.getContent("description"));
response.setMetaDataImage(data.getContent("image"));
response.setTitle(data.getContent("title"));
response.setMetaDataUrl(data.getContent("url"));
Data fetch is null.
I think you're talking about this library. If so, the boolean in the constructor serves the purpose:
public OpenGraph(String url, boolean ignoreSpecErrors) {
...
}
The way I use this library to fetch, for example, images is as follows:
OpenGraph og = new OpenGraph(url, true);
MetaElement[] imageElements = og.getProperties("image");
Perhaps you are just using the wrong getter? If the page has og tags, this snippet should work!
I had similar issues with opengraph-java (ie. getting null response).
I tried the example in the docs, but the response was null
OpenGraph movie = new OpenGraph("http://www.rottentomatoes.com/m/back_to_the_future/", true);
System.out.println("movie = " + movie)); // movie = null
Trying the false option for ignoreSpecErrors throws an exception java.lang.Exception: Does not conform to Open Graph protocol
So I made a library called ogmapper that's a little more flexible.
DefaultOgMapper ogMapper = new JsoupOgMapperFactory().build();
OgTags ogTags = ogMapper.process(new URL("http://www.rottentomatoes.com/m/back_to_the_future/"));
System.out.println("title = " + ogTags.getTitle()); // title = Back to the Future (1985)
Hopefully this is helpful!
I have a requirement to fetch the SenderName,SenderEmail,ToNames,ToEmails,CCNames,CcEmails from a lotus notes document instance.
Issue1
Looking into lotus.domino.Document API I found out the method getItems. When I write the elements to the system.out values for SenderEmail, ToEmails and CcEmails can be found.
However values for SenderName(a.k.a From), ToNames cannot be derived that easily.
The values seems to be using an common name format. For example check check my system.output below.
Principal = "CN=Amaw Scritz/O=fictive"
$MessageID = "<OF0FF3779B.36590F8A-ON80257D15.001DBC47-65257D15.001DC804#LocalDomain>"
INetFrom = "AmawScritz#fictive.com"
Recipients = "CN=Girl1/O=fictive#fictive"
MailOptions = "0"
SaveOptions = "1"
From = "CN=Amaw Scritz/O=fictive"
AltFrom = "CN=Amaw Scritz/O=fictive"
SendTo = "CN=Girl1/O=fictive#fictive"
CopyTo = "CN=Girl2/O=fictive#fictive"
BlindCopyTo = ""
InetSendTo = "Girl1#fictive.com"
InetCopyTo = "Girl2#fictive.com"
$Abstract = "sasdasda"
$UpdatedBy = "CN=Amaw Scritz/O=fictive"
Body = "Hello World"
The question is how can I get 'Amaw Scritz' from the common name 'CN=Amaw Scritz/O=fictive'. Is there any look up mechanism that can be used. (I would prefer to have a option other than doing a substring of the common name)
Issue2
is it possible to retrieve SentTime and ReceivedTime from mail document instance?
I know that there are two methods called getCreated and getLastModified. getCreated can be loosely associated with the SentTime and getLastModified can be loosely associated with ReceivedTime. Are there are other ways to get times for SentTime and ReceivedTime.
Issue3
How can one distinguish whether a mail document is a Sent mail or a Received Mail?
Issue1
You can use Name class.
Here example from this link:
import lotus.domino.*;
public class JavaAgent extends AgentBase {
public void NotesMain() {
try {
Session session = getSession();
AgentContext agentContext = session.getAgentContext();
// (Your code goes here)
// Create a hierarchical name
Name nam = session.createName(
"CN=John B Goode/OU=Sales/OU=East/O=Acme/C=US");
// Returns:
// John B Goode
// John B Goode/Sales/East/Acme/US
// CN=John B Goode/OU=Sales/OU=East/O=Acme/C=US
System.out.println(nam.getCommon());
System.out.println(nam.getAbbreviated());
System.out.println(nam.getCanonical());
} catch(Exception e) {
e.printStackTrace();
}
}
}
Issue2
Use values of PostedDate field and DeliveredDate field of mail document.
Issue3
Check that $Inbox folder contains your mail document. Or take a look at Dave Delay answer.
I agree with #nempoBu4 on Issues 1 and 2. I disagree with the answer to Issue 3. A received message can be removed from the inbox, so checking $Inbox doesn't help you distinguish between sent and received messages.
Assuming you have the document open, the best approach is to check two items. Sent and received messages both have a PostedDate item, but only a received message has a DeliveredDate item. Incidentally, a draft message has neither PostedDate or DeliveredDate.
