ordering of env-entry sub elements

Hi All,
Can anybody tell me whether the order of sub elemnts of env-entry in web.xml does matter?

Like, are the following two entry same?

<env-entry>
<env-entry-name>message</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
<env-entry-name>Hello!</env-entry-name>
</env-entry>



<env-entry>
<env-entry-name>message</env-entry-name>
<env-entry-name>Hello!</env-entry-name>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>

I tried both of this example in tomcat 6. Both of them worked well. But the second example fails xsd validation. I am really confused.


Thanks, Tridib

As of version 2.4 of the spec, the env-entry element contains :
- optional description (zero or more)
- one mandatory env-entry-name
- one mandatory env-entry-type
- one optional env-entry-value

Your container may be a bit lenient on this. Just don't trust it, and write environment entries as described in the spec.

Can we expect such questions in the actual exam??

I don't think so. But you may have something about the env-entry tag itself. You have to know what it is used for.
