can i compile .tag files on the fly? please help :(
hey all,
i'm looking for a definitive answer:
can .tag files be compiled on the fly, or do they always require a recompile
and restart for changes to take effect?
we currently have jsp's set to compile on the fly, and it makes dev so much
easier/faster.
is there any alternative, if not the same very dynamic editing ability of
.jsp's?
running tomcat 5.02a.
thanks so much!!!!!

Nor have I, directly :-) I meant, "why don't you just change a test
.tag file and see what happens?" Would have taken less time...

Yes.

6.0.x

I believe it's controlled by the "development" parameter to the JSP
servlet -- see the $CATALINA_HOME/conf/web.xml -- default setting
is "true", so no action necessary unless you've changed that.

thanks much for the reply.
haven't tried yet... i've never used jasper and would have to research it
(someone else on my team set up our build process), so i was asking this
first.
"I've never compiled
a tag file manually, nor restarted TC to see a change."
so this means you edit a .tag file, hit refresh in your web-browser, and you
see the change? that would be great and exactly what i want to happen.
what version of tomcat are you running? any ideas where you configure this
type of behavior?
thanks again,
john

Did you bother to try?
In any case, I don't know if this is "definitive" but I've never compiled
a tag file manually, nor restarted TC to see a change.
FWIW,

If you are really running 5.0.2 Alpha you need to upgrade. That version is
over 5 years old and the 5.0.x branch hasn't been supported for some time.
On current versions compilation on the fly does just work.

Your Tomcat version is a bit odd, since there never has been such any such level (Tomcat does not use any alphabetic characters in its versioning). If it's some offshoot of 5.0.2, that level is over 5 years old and I don't think it was ever officially released. Also, all Tomcat 5.0 levels are now deprecated (i.e., unsupported).

thanks again for the replies.
i guess i wasn't clear... i, of course, have tried this; the status quo is
(and has been) that our team has to restart the server for any .tag changes
made. it has been this way since i was hired a year ago, and, of course,
we'd benefit greatly from being able to tweak changes in real time.
and i agree with you, i know our tomcat is old :) unfortunately, we're
stuck with it right now.
i saw these in the spec:
"Upon deployment, the JSP container must search for and process all tag files
appearing in these directories and subdirectories."
"For each tag file in the web application, a tag handler is made available
to JSP
pages and other tag files. The specifics of how this is done are left up to
the Con-
tainer implementation. For example, some Containers may choose to compile
tag
files into Java tag handlers, whereas others may decide to interpret the tag
handlers."
so my question is, can tomcat 5.02a be configured to compile .tag files on
the fly? again, this is not the case for our current configuration.
thanks again,
john

I would guess from a brief look at the jsp 2.0 spec, the answer is yes,
but didn't read far enough to be absolutely sure. You could read the
spec yourself for a definitive answer or just try it... Personally I
find reality more fun.
- write a test tag
- write a jsp to test it
- run the jsp test
- modify the tag file only
- run the jsp test again
BTW, you should *really* upgrade your version of tomcat. You'll be
happier with the results.
