Are socket needed to send emails?????

hi guys,
lets say i need to send an email notification everytime i finish doing a cetain task....do i need to create and use a socket to send these emails????
thanks in advance for any help...
lost and blur.
Below are the codes to send email:
(So are socket needed???)
public void execute(String mailto, String mailcc, String mailsub, String mailbody){
//session object inside the catch block also(in case of DCOException).
DCOSession ds = null;
try{
ds = new DCOSession(); // Create new DCOSession object
ds.login("erstest02"); // Log in as current Notes client user
DCOMail dm = new DCOMail(); // Create new DCOMail object
dm.setDcoSession(ds);// Pass DCOSession to mail
//dm.setDebug(true);
dm.setSendTo(mailto);
dm.setCopyTo(mailcc);
//dm.setBlindCopyTo();
dm.setSubject(mailsub);
dm.setBody(mailbody);
//System.out.println("before mail sent");
dm.send(); // Send the mail
ds.logout(); // Log out of the session
System.out.println("mail sent to "+mailto);
}catch(DCOException e1){
e1.printStackTrace();
try{
if(ds!=null){
ds.logout(); //Log out of session even if exception is thrown
}catch(Exception ee1){
System.out.println("Exception thrown while trying to logout of session");
ee1.printStackTrace();
}catch(Exception e){
e.printStackTrace();
try{
if(ds!=null){
ds.logout(); //Log out of session even if exception is thrown
}catch(Exception ee2){
System.out.println("Exception thrown while trying to logout of session");
ee2.printStackTrace();
}

lets say i need to send an email notification
everytime i finish doing a cetain task....do i need
to create and use a socket to send these emails????Yes, sockets are needed to send emails. However, you don't need to deal with them yourself. You can use the JavaMail API. It will hide those low level details from you and let you deal with concepts that are related to sending emails--addresses, contents, servers, etc.

  • Need to send email with content of total sales

    Hi experts,
    I have configure notification mailer and have received also test email. Usually I may receive oracle alerts in my email address.
    I need two solutions or need to build below mention point.
    1) need to send email total daily sale ?
    2) need to setup oracle alerts ?
    I am waiting your kind response or refer solid documents to fulfil my requirements
    Thanks

    You can configure an alert that fires every day at about 1:00 am.
    The alert can query oe_order_lines_all table for all orders lines that were created in booked status on the prior day.
    Then you can format the alert to include the total amount.
    You can group by sales person or by warehouse.
    If you want to group the sales by item numbers, the email may become long depending on the number of items you sell every day.
    See http://docs.oracle.com/cd/A60725_05/html/comnls/us/alr/summary.htm for a great example on how to send a summary alert.
    Hope this helps,

  • Need to send email to email addresses in one list when list 2 is updated

    I have  2 lists
    list 1 has email addresses
    the 2nd list is actually a document library
    what I was wondering, is how can I send an email to people to people in list 1 when list #2 is updated with new documents?
    i have been trying different  ways of doing it, but no luck....
    anyone have any ideas how to capture the email address from list 1 and send them an email when list #2 is updated?
    seems straight forward but cant find the logic...

    Hi,
    I would suggest you to go for custom event receiver using visual studio. Its an easy way.... try it out.
    Choose List item event in event receiver settings.
    Step 1:Add item was added and item was updated event. Use caml query to fetch email address and loop through the collection and send email using SPUtility. Refer below code.
    /// <summary>
    /// An item was added.
    /// </summary>
    public override void ItemAdded(SPItemEventProperties properties)
    //base.ItemAdded(properties);
    using (SPWeb web = properties.OpenWeb())
    SPQuery query = new SPQuery();
    query.Query = "<OrderBy><FieldRef Name='Title' Ascending='False' /></OrderBy>";
    SPList emailList = web.Lists["List1"];//The list which has the email addresses
    SPListItemCollection listItemCollection = emailList.GetItems(query);
    foreach (SPListItem item in listItemCollection)
    SPUtility.SendEmail(web, true, false, item["emailAddress"].ToString(), "Your Mail subject", "Your mail body");
    /// <summary>
    /// An item was updated.
    /// </summary>
    public override void ItemUpdated(SPItemEventProperties properties)
    //base.ItemUpdated(properties);
    //you can provide same code here..if needed.
    Step 2: Provide the list2(document library) path as the ListUrl in Element.xml
    <?xml version="1.0" encoding="utf-8"?>
    <Elements xmlns="http://schemas.microsoft.com/sharepoint/">
    <Receivers ListUrl="/list2/"> <!--provide document library path...-->
    <Receiver>
    <Name>EventReceiver1ItemAdded</Name>
    <Type>ItemAdded</Type>
    <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
    <Class>SharePointProject1.EventReceiver1.EventReceiver1</Class>
    <SequenceNumber>10000</SequenceNumber>
    </Receiver>
    <Receiver>
    <Name>EventReceiver1ItemUpdated</Name>
    <Type>ItemUpdated</Type>
    <Assembly>$SharePoint.Project.AssemblyFullName$</Assembly>
    <Class>SharePointProject1.EventReceiver1.EventReceiver1</Class>
    <SequenceNumber>10000</SequenceNumber>
    </Receiver>
    </Receivers>
    </Elements>
    Deploy it to your SharePoint farm..make sure the feature is activated..and enjoy..
    Probably this should work..Check it out and let me know..

  • I need to send email in future specific day how can i do this ?

    If someone can helps thanks alot.

    Hi,
    You go for following approach :-
    1. Maintain a table with contains all date when you need to send mail. it can be one date or many.
    2. create a custom program which will first read this table above and see if todays date does exist in table.. if yes it will send mail else not.
    3. Now schedule report on daily basis. 
    Thats it. When ever you want to send mails just enter those dates in this table. it can be any no of future dates.
    Hope this helps.
    Enjoy SAP.

  • HELP!!! My settings are wrong need to send for printing

    Hi
    I am doing brochure's for my company. I am from South Africa.
    I use Illustrator for the brochure, Layout and Text.
    Last month the printer had problems with printing the brochure. I discovered my settings are wrong.
    This was the settings:
    Colour Setting
    Settings:     Custom
    WorkingSpace
    RGB:               sRGB IEC61966-2. 1
    CMYK:            U.S. Web Coated (SWOP) v2
    Color Management Policies:
    RGB:               Off
    CMYK:             Preserve Numbers (Ignore Linked Profiles)
    Profile Mismatches:  Ask When Opening (ticked)
                                   Ask When Pasting ( Not Ticked)
    Missing profiles:       Ask When Opening (Ticked)
    Then I did research On Adobe Community Help and changed it to the below but its wrong too
    Colour Setting
    Settings:     Europe Prepress 3
    WorkingSpace
    RGB:               Adobe RGB (1998)
    CMYK:            Coated FOGRA39 (ISO 12647-2:2004)
    Color Management Policies:
    RGB:               Preserve Embedded Profiles
    CMYK:             Preserve Numbers (Ignore Linked Profiles)
    Profile Mismatches:  Ask When Opening (ticked)
                                   Ask When Pasting (Ticked)
    Missing profiles:       Ask When Opening (Ticked)
    Can someone help me to set it right according to RSA printers settings, something like a default setting.
    Last Month the printer said the below:
    - fonts are not embedded.
    - black is not on overprint and is 4 colour black
    I never had this problem before, so I have no idea what went wrong all of a sudden.
    Now when I open my prevoius work on Illustrator or Photoshop, a small window pops up saying work is not according to this settings, etc.
    Please help. Im desperate.
    I need to start my new brochure tomorrow
    Thank you in advance
    Kajal

    You should get a preflight checklist from your print vendor.  Here's what I have set in Illustrator...
    You should also send the print vendor a press-ready PDF.  Not all of the file problems are limted to color settings.  For instance...
    "Last Month the printer said the below:
    - fonts are not embedded. "
    When you Save As > EPS, select "Include Fonts" in the selection process; and when Save As > Press Quality PDF, select "Embed Fonts" in the Settings dialogs.
    "- black is not on overprint and is 4 colour black"
    In Preferences > Appearance of Black, select "Accurate Black" in both screen and print; in your file, set appropriate Black elements to Overprint in the Color "Attributes" dialog.
    Whenever you are not sure what the printer is talking about, ask them to explain what they mean and help you fix the problems.  If they refuse, ask them where you can get help.  Most good shops will be willing to help you.

  • Server socket needs to sends images to applet

    Dear expert programmers
    I've got a simple socket server ruuning on my machine which accepts a connection from an applet on an arbitrary port.
    The problem I have is that it needs to "CONSTANTLY" take screenshots of the desktop and send them to the applet so that the applet can load them for people to see. It's a remote desktop project I've been working on for some time now and I have no idea on how to create images and send them using sockets to an applet.
    Could someone please help me - sample code would be appreciated - also efficiency of sending desktop scrrenshots isn't an issue for now.
    Many thanks

    ok, need to know what you have/can get working....
    have you got any working commuincation between Applet and server?
    could you write a method that converts int to 4 bytes?
    and use that to convert int[] to byte[] (4 times as big)?
    for the screen capture part..
    Robot robber=new Robot();
    BufferedImage bi=robber.createScreenCapture(new Rectangle(0,0,screenWidth,screenHeight));
    int[] pixels=bi.getRGB(0,0,screenWidth,screenHeight,null,0,screenWidth);
    byte[] data=toByteArray(pixels);get the outputStream from the connected Socket and use its write(byte[] b) method to send the data
    at the Applet, get the InputStream, use its read(byte[] b) method to get the data
    re-pack to int[] and use setRGB(0,0,screenWidth,screenHeight,int[] data,0,screenWidth)
    get the Graphics Object for the display element of the Applet you want to show the image and use drawImage(BufferedImage,0,0,null) to display

  • I desperately need to send emails from Sage Accounts linked with Firefox and not Outlook Express. Tried everything

    I am using Sage Instant Accounts and need to email customers their invoices directly. I have recently changed computer and upgraded Sage and I can no longer do this although could do it last week. I used to be able to go into email in Sage and Firefox would automatically come up with my contacts etc.
    I think Sage looks to Outlook Express. If I delete Outlook Exp will that be an answer?
    Have phoned Sage but they have no further answers. So need help as spent too much time!

    I use Outlook so this might not be quite the same with Outlook Express.
    After I set up an email account I can 'Test' the account settings which effectively sends a test email from the account to itself. If that is possible then check which way works i.e. the sending or the receiving of the email. If it is just the incoming part then this could be that you need to tick the box in the account settings that says 'My outgoing server requires authentication'.
    Other than that check your incoming and outgoing servers which, if you're using btinternet should be both set as mail.btinternet.com, I also suggest you check your username and password.
    Good luck!

  • Unable to send or receive emails! When I first bought my Macbook I never paid for the mac mail. I have tried to find Mobile Me to no avail. What software program do I need to send emails??

    Hi all! I bought my macbook pro around two years ago. I currently have the Snow Leopard operating system. I have just clicked on Lion to upgrade however I am aware that the Mac Mail required you to pay for it? I click on the mail link and it does not work i.e. the send button is greyed out. Please advise?

    You don't need to pay anything extra for Apple Mail. You may need to pay extra money to Yahoo and/or Hotmail if you want to connect to them with a true e-mail client like Apple Mail. I would provide links for more information, but it appears to be not quite supported. I think it is a service for mobile applications that people on computers can connect to if they hack around a bit. Your ability to connect with Apple Mail depends on how much you want to hack around.
    The easiest solution would be to wait a few weeks until Apple rolls out iCloud. Then you will be able to sign up for that instead of the defunct MobileMe.

  • HT3228 Need help sending email from iPhone 5S

    Have a new iPhone 5S and can receive email but every email I try to send is copied to the outbox and message says the recipient was rejected by the server. How do I fix that?

    You can't use iCloud to do that.  Any photos in iCloud must also be on your phone.  If you delete them from your phone, they will also be deleted from iCloud and they will be lost.  You might want to try updating your phone using iTunes on your computer (as explained at the bottom of this article: Update your iPhone, iPad, or iPod touch iOS software).  It requires much less space than updating over the air.
