hi

i want something like following (MVC architecture)

When user login i'm creating DOM instance. When user click on addNode Button
1 NODE get added to my XML document object
<DOC>
<NODE>
...
...
...
...
</NODE>
</DOC>

and than again user clicks on addNode button the another node should be added to my XML Document

after 2nd click
<DOC>
<NODE>
...
...
...
...
</NODE>
<NODE>
...
...
...
...
</NODE
</DOC>

currently when i 2nd time click on addNode button it creates a new XML Document object. and than add 1 NODE to that newly created XML Doc.

i guess this is something related to session... am i right ?

so when the same user is clicking on the addNode button.
it shuld first check if Document is there or not else it should create a new document object and than add a new node to it.

This should be executed once per user session and doc shuld be available to entire application.

how it is possible ?

In the addNode logic first getSession by cllaing getSession(false);
I think you will have always session so this will return a session object then call isNew() method on this if it new create the Document else just add node to the document. Hope it may solve........

Deepak.
 
It is sorta covered in the JavaRanch Style Guide.
