Re: How to avoid the line breaks when a tag file used within javascript?
Rick,
Here'a a bogus example:
dummy.jsp:
--
%@ page contentType=text/plain %
%@ taglib prefix=tags tagdir=/WEB-INF/tags %
Tag output: 'tags:dummy/'
dummy.tag:
--
%@ tag body-content=scriptless %%--
--%%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; %%--
--%c:out value=Hello, world!/
The file ends here^, not on the next line. The output is:
Tag output: 'Hello, world!'
So it should be possible to do what you want, it's just a matter of doinking
with the tag file...

The problem is when I try to do:
(All of this on one line ...sorry for crummy wrapping. I can send as
text if you want)
span style=cursor:hand; onmouseover=return overlib('tags:DelimItems
items=${associate.additionalServices} property=code postDelim=

The problem is in this part:
onmouseover=return overlib('tags:DelimItems
items=${associate.additionalServices} property=code postDelim= ,/');
The source looks like:
onmouseover=return overlib('foo,bar,foo,bar -- LINE BREAK!
');
The Line Break above is what is messing up. The output of the Tag
file(DelimItems) is fine, but the break it ends up giving at the end is
what is messing it up (the same break you noticed in your code). Also, I
don't want to make the tag file javascript specific since I use this tag
for other html output which is fine. I could of course make a modified
tag or pass in a param to produce the javascript from the tag file. That
might not be a bad option but still sort of annoying.

Re: How to avoid the line breaks when a tag file used within javascript?
It still causes the same problem. The problem is in the break 'after'
the whole tag is used. The break on the JSP that calls this tag. To be
sure, I used your exact code below and I still get the same break that
is visible when you view source. To be specific:
When the tag is called in the following onmouseover:
In JSP:
span style=cursor:hand; onmouseover=return overlib('tags:DelimItems

So you don't have a blank line after the /c:forEach?
eg you have
[start of file]%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core;
...
( includeLast || !status.last )}'${postDelim}/c:if/c:forEach[end of file]

[start of file]%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core;
...
( includeLast || !status.last )}'${postDelim}/c:if/c:forEach
[end of file]
I imagine you haven't pressed enter at the end of the /c:forEach
Perhaps you could try assigning the result to a var
eg
c:set var=${output}tags:DelimItems
items=${associate.additionalServices} property=code postDelim=
,/'); onmouseout=return nd();*c:out value='${associate.primaryService.code}' default='N/A'//c:set
Then use
span style=cursor:hand; onmouseover=return overlib('c:out

Good suggestions. I'll have to try them out. I know the JBoss instance
3.2.5 is using Tomcat5.. I just have to figure out where the tomcat
settings are configured for it. (New to using JBoss).

Re: How to avoid the line breaks when a tag file used within javascript?
This thread has gotten too long to ignore :-)
trimSpaces probably won't do it for you.
As my bit, I tried this trivial JSP:
%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; %%--
--%tag attr=foo('jsp:include page=test.jsp /')%--
--%anotherTag /
where test.jsp is another trivial JSP as follows:
%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; %%--
--%A, c:if test=${true}%--
--%B, %--
--%/c:ifC
I don't have a newline after /c:ifC, and I get this output:
tag attr=foo('A, B, C')anotherTag /
Ugly code? Yes. But I believe the output is similar to what you want from
your example.
Now why it doesn't work for you is another issue. I'm using Tomcat and
Emacs.

Right, got it. The problem is in the DelimItems.tag file.
I'm still confused:) Here's the DelimItems tag file:
(had this all one line but broker out the imports as shown)
%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core;
%%@ attribute name=items required=true type=java.util.Collection
%%@ attribute name=preDelim
%%@ attribute name=postDelim
%%@ attribute name=property required=true
%%@ attribute name=includeFirst type=java.lang.Boolean
%%@ attribute name=includeLast type=java.lang.Boolean
%c:if test='${preDelim == null postDelim == null}'c:set
var='postDelim' value=', '//c:ifc:forEach items='${items}'
var='item' varStatus='status'c:if test='${preDelim != null (
includeFirst || !status.first
)}'${preDelim}/c:if${item[property]}c:if test='${postDelim !=
null ( includeLast || !status.last
)}'${postDelim}/c:if/c:forEach
Here's the exact line that calls it (all one line):
span style=cursor:hand; onmouseover=return
overlib('tags:DelimItems items=${associate.additionalServices}
property=code postDelim= ,/'); onmouseout=return
nd();*c:out value='${associate.primaryService.code}'
default='N/A'//span
What I'm confused at is when you say the prolbme is IN the
DelimItems.tag file? I've had the file all is one complete line with
no returns but will still get a break in the JSP where it's used. I'm
sure I'm missing something obvious here:)
Here's something that
might trip you up. This tag file (EOF is just the end-of-file
marker so
it's
explicit in the example, it's not really in the tag file):
%@ tag body-content=scriptless %%--
--%%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core;
%%--
--%c:forEach var=s items=0,1,2,3
${s}
/c:forEachEOF
Will produce:
Tag output: '
0
1
2
3
'
But this tag file:
%@ tag body-content=scriptless %%--
--%%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core;
%%--
--%c:forEach var=s items=0,1,2,3%--
--%${s} %--
--%/c:forEachEOF
Will produce:
Tag output: '0 1 2 3 '
So be careful with your handling of nested tags...

Now that drives me mad:) If you get a chance, just so I can tell if ends
up being some server or OS situation. If you could send me that JSP and
the tag file so I can plop them 'as is' into my app- that would be
great. I'd love to see what happens. Thanks.

[solved thanks all] Re: How to avoid the line breaks when a tag file used within javascript?
First off thanks everyone for being so patient. Somehow I had to have
been an idiot somwhere along the way in creating the Tag file even
though I swear I copied and pasted the code from Kris' initial e-mail
exactly like he had it. Plus I thought I triple checked for any trailing
line break. I say the problem is'solved' but I really don't know what
the problem was with my file. My tag file looked to me to be identical
to the one Kris ended up e-mailing me. Yet when I took what he emailed
and pasted it over my old tag file everything was fine. Is it possible
that somehow a hidden char was in there? I had that happen when time
when I was on Linux and I pasted from Eclipse into jEdit, or it might
have been the other way around. It was a real problem to track down
because looking at the file you couldn't tell anything was wrong but the
character that wasn't showing up was causing a problem with the JSP
compiler trying to compile the code. (I think in this case it ended up
going up as binary and that's how I know there was a problem.) Ok, I'm
digressing, I'm sure it was just typical stupid error but thanks again,
since my code looks much cleaner now.
Now it's time to go struggle with more javascript for an application
that I'm wondering will ever get out on time:)

Re: How to avoid the line breaks when a tag file used within javascript?
Rick,
Are you still pursuing this? If so, I use the following comment hack:
%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; %%--
--%%@ attribute name=items required=true
type=java.util.Collection%%--
--%...
I've also seen this in use:
%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core;
%%@ attribute name=items required=true type=java.util.Collection
%...

I created a simple forEach type of delimeter tag that works well for me
(code at end). The problem, though, is I need to use this tag within a
javascript method to produce a string that'll be used in a dhtml popup.
The problem is that, even if I make this tag file all on one line, I
still end up with at least one line break- that when used within the
javascript causes problems.
For example I need to call something like..
onmouseover=return doSomethingWithString('tags:MyTag .../');
Is there a way to avoid the line breaks that mess up the above
javascript? or I guess another option is to return a String from a
function vs using this as a tag file? (I've looked briefly at the
function stuff Kris, but I'm short on time on this app and the Tag file
was easier to start with).
As a side note if you see a better way to write this tag file I'll take
any suggestions (sorry the if part is hard to read but I needed no extra
spaces in the html output):
DelimItems

%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core; %
%@ attribute name=items required=true type=java.util.Collection%
%@ attribute name=preDelim %
%@ attribute name=postDelim %
%@ attribute name=property required=true %
%@ attribute name=includeFirst type=java.lang.Boolean%
%@ attribute name=includeLast type=java.lang.Boolean%
c:if test='${preDelim == null postDelim == null}'
c:set var='postDelim' value=', '/
/c:if
c:forEach items='${items}' var='item' varStatus='status'
c:if test='${preDelim != null ( includeFirst || !status.first
)}'${preDelim}/c:if${item[property]}c:if test='${postDelim != null
( includeLast || !status.last )}'${postDelim}/c:if
/c:forEach
If you don't provide a pre or postDelim, it just uses comma separated
output, which is what I most commonly need.

Thanks, yes still looking:( The problem is I'm still left with just one
closing break at the end. I had previously tried converting the whole
tag file to one line and still I'll get one break when it's evaluated in
the JSP. Very frustrating. The only other hack I can think of is when
I'm iterating over my loop in my tag file I can keep prepending a c:set
var to make my String and I could then use that in the JSP. Seems
like a lot overhead though. Be nice if there was a way to do c:set
var=foo value=tags:MyTag ...// Then I could just use ${foo}
within the javascript.

Re: How to avoid the line breaks when a tag file used within javascript?
You may be able to work around it via javascript?
Try outputting the value to a hidden text field than displaying the value
property. This will not cause a javascript error elliminates line breaks.

You're sure there's not a newline at the very end of your tag file?
