Order of elements in web.xml

[Pavan Kumar Tammana]

Hi all,
Can anyone tell me the order of elements we declare in deployment descriptor? I actually thought that the order doesn't matter. But when i was doing the mock exams i have seen some questions on this. I am actually using a SWT(Standard Web Toolkit) a plug-in for eclipse. Normally the tool alerts me if the order in web.xml is not correct, because it has the reference to the dtd in the deployment descriptor and i guess the validation is done by referring to the dtd. HFSJ book also doesn't talk anything regarding this. So can anyone help me with this???

Bates/Kathy/Bryan,
It will be a lot helpful if you can shed some light on this??

Thanks,

it doesn't matter with 2.4 - it does with 2.3

You are probably looking at old questions for the 2.3 spec.

oh - if you're using a DTD, it probably thinks it's 2.3

do you open web.xml like this ?:

    
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee <a href="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">" target="_blank" rel="nofollow">http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"></a>
 

or like this

 
<?xml version="1.0" encoding="ISO-8859-1"?>
 
<!DOCTYPE web-app
    PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
    "http://java.sun.com/dtd/web-app_2_3.dtd">    
 
<web-app>

Hi Daniel,
Sorry i meant xsd, i am referring to 2.4 version, so i am using the xsd in my web.xml. But don't you think during the schema validation it checks for the order, because i get errors/warnings if i shift the order of some elements.

Thanks,
