i am writing a mail server for lan i.e the members of a lan can write mail to the next
member of same lan
its only for the lan

i got a problem while storing the mail .......
i tried to do it using a simple file for each user and append the new mail to it
but this idea couldnot satisfy me

next idea struck i.e xml but i had problem in this

the problem is
i have the xml file as
......
..........
<mailbox>
   <mail id="1" flag="read">
       <from> cynic061 </from>
       <to> shankar </to>
       <subject> hi </subject>
       <date> 2061/3/13 </date>
       <message> hi how are the days going on thanks </message>
   </mail>
</mailbox>

here id specifies the mail number which can be used to delete the mail and the flag is to identify the unread mail

now every time the mail comes it has to be appended after </mail> i mean
when new mail comes then the xml file looks like

<mailbox>
   <mail id="1" flag="read">
       <from> cynic061 </from>
       <to> shankar </to>
       <subject> hi </subject>
       <date> 2061/3/13 </date>
       <message> hi how are the days going on thanks </message>
   </mail>
   <mail id="2" flag="unread">
          <from> cynic061 </from>
          <to> shankar subedi </to>
          <subject> problems </subject>
          <date> 2061/3/14 </date>
          <message> these problems are making tensed </message>
   </mail>
</mailbox>

how can i do these stuffs using java
please help me

Hi shankar,
We can do it by using dom object where input xml is read into the class and then appending the content of mail to this xml object. Please search for creating and using dom using java, you will get much information on this.
Hope this help u.


Thanks and Regards
Naveen.

I use a combination of JDom and Xerces which works very well for me.
