Best way is to start putting System.out's ....

Put the incremental numbering between several code blocks. Check the log output. You will surely be able to find out till what point ur code is Ok.

Help! Sporadic Mail sending issues

I have recently upgraded to Lion and since then have been having sporadic problems sending mail. I use a .mac account with O2 broadband at home and an unknown provider at work.
Mail stops sending for several hours at a time, and has done so from both locations. Since my iphone and ipad still send mail without a problem at these times, I have to assume that it is a Lion issue and not a provider issue.
Connection doctor shows green for incoming and outgoing but mail simply refuses to send.
My current mail-send-blackout has been going on for 18 hours now. Yet yesterday my mail would send from home and also when I arrived at work. But halfway through the working day it just stopped. Again. No apparent reason or pattern
If anyone has any suggestions, I'd be very grateful
Thanks
Cal

Yes well there were no changes to the account, just stopped sending mail via SMTP
Deleted account and set up new one, same thing cannot send mail via Mail app
As mentioned another disc on the same comp with same account details etc works fine
so don't understand
Seems a lot of people are having this problem too.
Thanks Anyway

Help requierd on mail sender adapter

i m workin on a scenario to send email from a mail server inbox to XI.i need to configure mail sender adapter....need step by step help on that.
regards,
latika.

hi latika,
the Message Structure to be defined depends on the message protocol that you are trying to use.
I would recommend using XIPAYLOAD. From the help link,
<b>XIPAYLOAD</b>
In this mode, the content of the e-mail is put in the payload of the XI message. If you do not set the Use Mail Package indicator, the information about the sender (From), receiver (To), and subject of the e-mail is lost.
If you have selected XIPAYLOAD as the message protocol, you must make the following additional specifications under Mail Attributes:
If you want to put the entire e-mail message including the header information (From, To, Subject) in the payload, set the Use Mail Package indicator. See the example below. The header information is included in an XML mail package format.
<i>
Source Structure</i>
<i><?xml version="1.0" encoding="UTF-8"?>
<ns:Mail xmlns:ns="http://sap.com/xi/XI/Mail/30">
<Subject>Subject</Subject>
<From>[email protected]</From>
<To>[email protected]</To>
<Reply_To />
<Content_Type>text/plain</Content_Type>
<Content>
This is the content.
</Content>
</ns:Mail></i>

Help with Servlet - JSP Newbie

I'm trying to teach myself jsp. I've created a couple of classes to do my data I/O. I have a form to collect user data and the page the form posts to should write the data to a text file. When I run the form and form handler the data is presented back to the user and everything looks fine... no errors or anything. However, the text file I'm trying to create/append does not get modified. Any suggestions would be greatly appreciated as I can't move on with what I want to do until I figure this out.

I just realized that the file is given as just a filename. No path.
Are you SURE the file isn't being created, just somewhere you don't expect?
Try putting a full path in there instead of just a filename.

Please help me with the jsp page

Hi,
I have a parent jsp page. I have a button in that page. If I click the button in the parent page, a child page will be opened which consists of huge data. I have set an option such that if I click the jsp page it asks to open directly or save so as to edit the data in MSWORD format. The child page has a print button at the end of the page which prints all the data. But since the data is very vast I want page breaks at certain places so that when I edit the data and click print button it prints the data with page breaks at certain points. I know that in MSWORD we have page breaks. But I should not do it manually as there would be thousands and thousands of pages to be printed.
ANY IDEA OR HELP IN THIS MATTER IS GREATLY APPRECIATED. I HAVE BEEN TRYING TO SOLVE THIS MATTER AND POSTED IN MANY SITES. BUT NOBODY RESPONDED. ATLEAST PLEASE LET ME KNOW IF THE IDEA WHICH I MENTIONED IS WORNG OR NOT.
THANKYOU

Automatic Mail Sending in Java/JSP/Servlets

Hi,
How to send mails with a specified format automatically after a stipulated no of days when the user does not access a file/page.
TIA

1. In your web application, have a database that keeps track of when a user accesses a page.
2. Once a day, run a program that scans that database looking for cases when a user has not accessed a page for N days, or whatever your criterion is. Use JavaMail to send an e-mail message to each of those users.
If you have specific questions about any of these things, don't hesitate to ask them in the appropriate forum.

Can you give some idea of how you have configured the datasource?
- using JNDI?
- hard coding it in the page?
What code do you use in the JSP to access it?

Object living with servlet/jsp container

How do I make an Object live until the servlet container lives? I mean I want an Object to be instantiated once in the lifetime of the webserver session and its has to be singleton and should live alive until the webserver dies? How can I make this possible? I should be able to keep that object alive even if any no references are made to the object. Moreover I should be able to access that object from any java class on that webserver?

You can't do this in memory. The easiest thing to do would be to read/write the persistant data you need from disk.
Anything your JSP or servlet creates in memory will be cleared when it is done serving the request.

Object living along with servlet/jsp container

How do I make an Object live until the servlet container lives? I mean I want an Object to be instantiated once in the lifetime of the webserver session and its has to be singleton and should live alive until the webserver dies? How can I make this possible? I should be able to keep that object alive even if any no references are made to the object. Moreover I should be able to access that object from any java class on that webserver?

if mean u want to keep the object live for
one user session
use session.setAttribute("name",object)
and if mean for the time btw start up and shutdown of the
server use application scope
alternatively
use session scope in bean or application scope as needed
like
<jsp:useBean id="db_in" scope="session" class="com.ww.ert.Bean_IN" />
or
<jsp:useBean id="db_in" scope="application" class="com.ww.ert.DatabaseBean_IN" />

Ejb + servlet + jsp

Hallo everybody,
i try to develop an application with servlet jsp and ejbs but i don't have enough information about this thema.
for example i want to make a simple login szenario :
user type the name and passwd and the system contact with the db and show a wellcome page if the login is succesfull and an error page if the login is unsuccessfull.
which component does was??
the first page can be a html form and post the name and passwd to a servlet.
in this case servlet can make a connection with the DB and can forward the user to next page or error page. BUT where should i use EJB? can i realize the db connection with ejb ? if yes how can interact the servlet with the ejb and how can i store the information (for example address of user) which i have taken from the DB?
thanks a lot

Thanks for the antwort
this means that the servlet connected to DB and execute the sql to authenticate user??
and the second part is my bigger problem :)
what does it mean "it will pass the control
to the enterprise java bean which will be housing the business logic for your application."
what does a java bean really do? how can i find information about them?
and is ther an example in which i can see how servlets, jsps and beans interact??
thanks

Help I would like to send an e-mail to a group of people, I have the group created, but when I drag it to bcc or to- it will not attach. can anymon help me with this?

In a new email message window start to type the name of the Group you have in Contacts/Address Book in the 'To' field - it should self-complete when it recognises the name.
(Note: this only works with 'normal' Groups and not Smart 'Groups').

Hi kirupa_sankar,
To send mails to others you have to use javax.mail.jar file and sample code is
import javax.mail.*;
import javax.mail.internet.*; // important
import javax.mail.event.*; // important
import java.net.*;
import java.util.*;
public class Mail {
Properties props;
Session session1;
Message message;
boolean flag=false;
public boolean sendMail()
props=new Properties();
props.put("mail.smtp.host","mail.website.com"); // 'localhost' for testing
session1 = Session.getDefaultInstance(props,null);
String from= "[email protected]" ;
String subject = "testing mail(subjective matter)";
message =new MimeMessage(session1);
message.setFrom(new InternetAddress(from));
message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("toaddress",false));
message.setSubject(subject);
message.setContent("content of the message");
Transport.send(message);
return true;
try this one you will get success....
