Why would you do a thing like that?

The file you posted desn't seem to have anything to do with generatng a view.

edward durai,
Javaranch tip:

If you are going to post more than a line or two of your code, wrap that
code in a set of UBB Code tags.
Doing so will help to preserve your code's indenting, making it easier to read.
If it is easier to read, more people will actaully read it and you will
stand a better chance of getting help with your question.
See UseCodeTags for more
help with UBB code tags.

Actually The above program is using to get the xml files each node names and node value.

Thanks

[Bear Bibeault]

OK, so I ask again. What does this type of processing have to do with JSP?

[Edward Durai]

actually my xml looks like

<fieldid>
<field f_id="0" sortingorder="3"/>
<field f_id="1" sortingorder="1"/>
<field f_id="2" sortingorder="2"/>
</fieldid>

i want to fetch the order only. ok. That's why I am using the above program. And it should work for both ie and firefox.

Thanks

edward, you're still not answering Bear's question It's an important one.

[Edward Durai]

Pardon me,I could not understand, what you are asking

[Ben Souther]

Building an XML document is not view manipulation.
This is not something you would ever want to do in a JSP.

Bear's question was very simple.
Why would you want to convert something like this into a JSP?

[Scott Johnson]

Edward, it sounds like you want to read an xml file and display it in the browser.

Is this correct?

If so, a more proper way to do this (and what Bear and Ben are hinting at) is to create a servlet. Especially for the part that reads the xml file.

Is this an academic exercise where you were told to write a JSP?
