Description arne anka

in a dynamic web project i use a jare file providing several tags.
the tld of those tags lives in the same jar file below META-INF/.

including the tld in a jsp
<%@ taglib uri="http://www.foo.com/bar-tags" prefix="foo" %>
looks ok, no warnings or errors.

starting to type a tag 
<foo:
the autocompletion offers all tags.
but once the tag is finished in the jsp

<foo:bar/>

there appear warnings about

Unknown tag (foo:bar).

"Open Selection" from context menu on both the taglib and the tag opens without fail the tld file inside the jar, hence it is available.
And yet, the validation constantly fails to recognize it.

As far as my personal experience with wtp and research show, it is a rather old issue which seems to keep popping up again and again ...

Where is the TLD within the .jar file and to version is the Dynamic Web Module facet set?  Can you attach the web.xml and tld file here?

the tld lives in META-INF/.
Dynamic Web Module facet is set to 2.5.

cannot attach the tld file -- and for the web.xml: the tld is not noted there, if that was what you want to check.

after a while sometimes the tag seems to be recognized, but not always and not in a reliable time frame.

Please retry this with SR2, as it sounds like it *might* be bug 325186.  Otherwise, without more concrete information I'm not sure what we can do.

Hi, Arne. Just checking to see if this was cleared up with SR2 as Nitin mentioned.

Resolving as fixed by Nitin's patch. Arne, if it has not been resolved in SR2, please reopen this defect. Thanks!
