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.

Sending Emails With Java

I'm trying to find out how to send emails with java - without using the java mail api - i've been told there is a way to do it but i cant seem to find it - any help on this would be gratefully recieved as i'm totally stuck! :(

Ok, I expanded on it a little bit. Still probably isnt totally correct.
String localhost="yourdomain.com";
String sendMailHost=�mail.domain.com�;
int portNo=25;
String from="[email protected]";
String to="[email protected]";
String message=�Message Body.�;
Socket s = new Socket(SendMailHost,portNo);
DataInputStream in = new DataInputStream(s.getInputStream() ) ;
PrintStream out = new PrintStream(s.getOutputStream() ) ;
out.println("HELO " + locahost);
out.flush() ;
in.readLine(); //ignore response
out.println("MAIL FROM: " + from);
out.flush() ;
in.readLine(); //ignore response
out.println("RCPT TO: " + to);
out.flush() ;
in.readLine(); //ignore response
out.println("DATA");
out.println(message);
out.println(�.�);
s.close();

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,

What do i need to know to send email using Java???

hi there
what do i need to know to build an application that sends email? thank you.

It would also help if you knew something about how Internet e-mail works. Such as what an SMTP server does, what relaying is and why it's bad, and so on.

Sending Email using java code

I am using the following code to send an email from my java servlet but the problem is, when it is on its own it works fine but as soon as I combine it with some code to submit data into a postgres database it sometimes does not perform could it be because im missing some close statements??

It's possible. It's only software, after all.
But it's not easy. It effectively involves
screen scraping the HTML pages.
There used to be a third party JavaMail provider
that did all the hard work, but it has disappeared.

Unable to relay - This happened because your Company network don't permit relay. Do talk to the network administrator and check with way safe you can send.
I got the same problem, now im using through gmail.

Can I send email using Java from my localhost(Tomcat) with Internet connect

Hi friends,
Please tell me can I send email from my localhost (Tomcat) using Java when my computer is connected to Internet?
I don't have any SMTP username or password or the like, as I found in some codes available in net.
Please suggest and any simple code if possible.
Please don't send me the link of JavaMail API to read.
---Sujoy

Thank you for the link. Though I have not tested the provided code, I will test it.

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/"> 
<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..

Dinesh
