How to make idea recognize external tag libraries

You posted this ages ago, but no one replied. I'm having problems with this right now. Perhaps you remember what the problem was. Any suggestions?

I'm not sure if you're having the same issue, but this might help:

Although I never got any responses either, my post does mention a workaround that allows JSP compilation.

IDEA doesn't understand the 1.1 taglib syntax right now. You'll have to convert your taglib descriptors to 1.2 (mainly changing DOCTYPE and adding hyphens to some tags).

Or you can wait. People working on IDEA has said that they want to have this fixed in the next couple of builds.

It's already fixed in 819, but 819 is not out yet of course :)

I changed my descriptors to 1.2 and everything seemed to work just fine. BE
CAREFUL though because if you just change the descriptor to point from:

<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library
1.1//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_1.dtd">

to this:

<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library
1.2//EN" "http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_2.dtd">

You will get exceptions in IDEA. The reason for it is that when you make
the change and fetch the external resource, IDEA does just that, does not
check anything that's been downloaded and assumes that it's the proper
format. The problem is that the URI above gets you a file with this in it:

"The file named http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_2.dtd
has been renamed to http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd
in the most current version of the specification.
Please update your application to use the new name."

Of course if you try to open a JSP document, it's going to try to parse the
resource for what it needs and throw exceptions. The exception thrown has
been fixed in 819, but not the fact that they somehow need to check if the
file downloaded is valid.


This is the correct DOCTYPE:

<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library
1.2//EN" "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">

After you've set this, you'll need to add a - to about 6 tags (I might have
forgotten some):
tlibversion = tlib-version
jspversion = jsp-version
shortname = short-name
tagclass = tag-class
bodycontent = body-content
teiclass = tei-class

Hope this helps.

As the matter of fact you can just change the DTDs uri and I think it should work just fine. Now this problem seems to be fixed and if you'll have any troubles with 1.1 format in 819+ builds please file bugs.

Thanks,
