Sanjiv,
Thanks so much for the tips. A little more clarification would help a
lot.
1. Yes, I do need to present the data in a grid after combining data
from 2-3 XMLs and grouping them in a particular structure. Here's a
simple version of what this looks like:
1st XML: (sectors.xml)
---------------------------------
<Sectors>
<Sector id="10">Consumer Discretionary</Sector>
<Sector id="20">Consumer Staples</Sector>
<Sector id="30">Energy</Sector>
</Sectors>
2nd XML: (stocks.xml)
---------------------------------
<Stocks>
<Stock id="APEI" sectorId="10">APEI</Stock>
<Stock id="EL" sectorId="20">EL</Stock>
<Stock id="EVEP" sectorId="20">EVEP</Stock>
</Stocks>
I need to read both and present them in a grid like:
Consumer Discretionary Consumer Staples
------------------------------------ --------------------------
APEI EL
EVEP
I want to read the XMLs and organize the data in a value object. Then
I can use this to create the Store and pass to something like
GridPanel. Pl suggest if my approach is correct.
2. Also, these XMLs may get updated every few minutes. I have to keep
reading these and flowing back to client. Does the servlet idea work
for this where server should be pushing data to client?
And a general request: the demo URL doesn't work for me. It fails with
a java script error (on line 299) which looks like: function ucc(a)
{if(a<=30){return 1<<a}else{return ucc(30)*ucc(a-30)}}.
Thank you so much for all help.
