Confusing Tag-directive

Given -


has been placed in /WEB-INF/mytlds/tld1.tld

is invoked using <mytags:tag1 />

whats is the correct tag directive for this ?

1. <%@ taglib prefix="mytags" uri="/WEB-INF/mytlds/tld1.tld" %>
2. <%@ taglib prefix="mytags" uri="http://abt.com/tld/mytaglib" %>


I always asumed that the uri in the directive MUST match with the uri in the tld, therefore choose 2nd one but seems like its incorrect and the 1st one is correct.
I havent been able to convince my self, can someone help me out ?

Using the URI defined by the TLD is the best approach.

Second one is wrong URI http://abt.com/tld/mytaglib
where as TLD is showing http://abc.com/tld/mytaglib

Hi Madhup,

Both Bear and Rajeev are correct here, but the explanation why

is allowed here is found in the specifications (jsp2.0)
JSP.7.3.6.1 Computing TLD Locations
[removed... just have a look at this part later..]
JSP.7.3.6.3
Finally, the fallback rule allows a taglib directive to refer directly to the TLD.
This arrangement is very convenient for quick development at the expense of less
flexibility and accountability.

Regards,
Frits
