Method 1
Its the use of the apex:outputtext component that causes everything to remain on the same line. If you simply use the merge fields, the line breaks work as expected. E.g.
<apex:page Controller="ContactQuery" contentType="text/plain/#emp.txt" cache="true">
<apex:repeat value="{!cs}" var="contact">
{!contact.Name} {!contact.Id}
</apex:repeat>
</apex:page>
Opening the output file in vi, shows the following – the line numbers indicate that each entry is on a new line:
Elsewhere you have indicated that you are using notepad to open the output file – the problem here is that notepad expects each line to contain a carriage return followed by a line feed, whereas the text file simply contains a line feed. You can handle this server side by building a string that contains the contact elements you are interested in plus the carriage return line feed characters.
Revised controller (updated to include fixed size name):
public class ContactQuery{
public List<String> contstr {get; set;}
public string empId;
public contactquery()
{
contStr=new List<String>();
for (Contact c : [Select id, Name from Contact ])
{
String nameStr=c.Name.rightPad(40);
contStr.add(nameStr + ' ' + c.Id + 'r');
}
}
}
Revised page:
<apex:page Controller="ContactQuery" contentType="text/plain/#emp.txt" cache="true">
<apex:repeat value="{!contstr}" var="str">
{!str}
</apex:repeat>
</apex:page>
Opening the output from this page in vi shows that there is a carriage return at the end of the line (the ^M character), followed by a line feed, and each name is padded to 40 characters:
Method 2
It working correctly, have changed the code for (Contact c : [Select Name,Phone,Email,Fax from Contact ]) { cs.add(c.Name.rightPad(40)+ c.Email.rightPad(30)+ c.Phone.rightPad(20)+c.Fax.rightPad(20) + ‘r’); }
