Is the order of listener and servlet tags matters in DD?

eg. is the following invalid?

Yes the order is necessary. <listener> element precedes the <servlet> element.

Sorry Bassam, but I don't agree. According to Servlet spec 2.4, SRV.13.4:
"1. web-app Element
...
All sub elements under this element can be in an arbitrary order."

So the order doesn't matter under <web-app>

I agree with u Jose... I guess, this order thing has been made lenient starting from servlet spec 2.4. so, we can have elements within in any arbitary order... unless, u know that the order matters to u... like in the case of ordering of filter DD elements...

Thanks Jose Esteban for indicating the error. It is really astonishing to know that order is not necessary. I think till Servlet 2.3 it was necessary. Am I right?

HFS on page 174 shows example of listener tag at the end of the DD so it seems that Jose's the man. Order is not important.
