Keeping strictly with the JSP directives (the issue
can be extended to the JSP tags as well, but it
gets more complicated) common sense is enough, I
hope, to realize that whenever you add a directive
you really don't want an empty line in your output.
These empty lines are annoying at best (every time
you check the source of a page generated by JSP you
first see an empty page - quite stupid), and breaking
your app at worst (like in the case of IE).
The absolute best proof that there is a problem
here that needs fixing is the fact that developers
make their code unreadable just as a work around.

that tags could be marked as not generating any output, so when in a 
single JSP line there were only such marked tags and leading /

You are not asking the directive to scan anything,
the page compiler could consider white space and newlines
after a directive as part of that directive.

Re: xhtml and Internet Explorer

2003-11-04 Thread Rodrigo Ruiz
Well, not necessarily unreadable, just different ;-)

I usually play with the tag delimiters to allow some readability. For 
example, my JSPs usually begin with something like:

[EMAIL PROTECTED] contentType=...
   import=...
   import=...
   errorPage=...
%%!
 // class code

%%

 // service code

%!DOCTYPE ... 
...
And if I need to place two directives with no spaces in between, I write

jsp:useBean 
   id=data scope=request class=my.Data
/jsp:getProperty
   name=data property=aField
/
   

It is not as clean as a directive per line, but at least it doesn't hurt too much :-P

Rodrigo

 That's because IE ignores the Content-Type header and just looks at the
 first few bytes of the file to decide how to display it. What a POS.
 Anyway...
(Christopher Schultz)

IE works like this: in the first call to a web page, it checks the
Content-Type and displays the web page accordingly. Next time you request
the same page, it ignores the Content-Type.

  I know that this issue came up before on this
  list, but the solution suggested previously

(Marius Scurtescu)

So, do the following:
1. You have to make sure IE is foing to display the most recent page. You
can do this by either adding a pragma/no-cache header, or go to (in IE):
tools/internet options/temporary internet files/settings and, under check
for newer versions of stored pages, select the every visit to the page
option. When you are developing, this last thing should ALWAYS be done.
Otherwise, you might be getting IE cached versions of the web page and
asking yourself why the changes aren't working.
2. Force IE to read the Content-Type again. Simply shut down the browser,
and request your xhtml page to see if it works.

Hope that helps.

Re: xhtml and Internet Explorer

2003-10-30 Thread Marius Scurtescu
Thanks for all the replies. I did solve the mystery.
IE is indeed a POS.
It looks like it completely ignores the Content-Type
headers and it just scans the beginning of the file.
The JSPs I was struggling with are using lots of JSP
directives (tag lib and page), includes and tiles.
The result was that there were many empty lines after
the DOCTYPE declaration and the html tag. IE seems
to be scanning for the html tag (don't ask why) and
if it does not find it soon enough then it gives up
and treats the file as raw XML. Pretty smart.
I attached a test file which on my system is treated
as raw XML. If I delete on single empty line before
the html tag then it is treated as XHTML.
Now this is sort of a show stopper for me, unless I
find a way to reduce the empty lines a the top of
a file. Is there a way in Tomcat to prevent the
creation of an empty line for each JSP directive?
I cannot move the html tag on top since it is
generated in a layout file and imported through
tiles.
A few more observation regarding IE. It seems that
one it guessed the type of a page it is caching that
info in memory. Deleting temporary files and forcing
a check on every visit does not help. You have to
close the browser in order to flush this cache.
Loading pages from the file system has a completely
different logic, it is based on the file extension
(there is no scanning for html tag).
Thanks again,

Put all the tag and page directives on one line. Looks horrible in the 
source but if it works...

The alternative is to write a filter which wraps the response and strips 
off the empty lines at the beginning as they are written to the 
outputstream.
We've implemented this and it works quite nicely. We restrict it to 
text/* content-types ;) The only downer is the additional broken pipe 
IOExceptions that we now log when someone hits stop in their browser. :(

If you have multiple JSP directives at the tops of your pages, consider 
putting them onto the same line. For example:

[EMAIL PROTECTED] import=... %
[EMAIL PROTECTED] language=Java %
jsp:include page=foo.jsp /
jsp:include page=bar.jsp /
jsp:include page=baz.jsp /
Maybe change this to:

[EMAIL PROTECTED] import=... %[EMAIL PROTECTED] language=Java %jsp:include 
page=foo.jsp /jsp:include page=bar.jsp /jsp:include 
page=baz.jsp /

Also note that all of your [EMAIL PROTECTED] ... % directives can be put together 
into one directive, which uses less space.

Tomcat really can't be blamed, because you are putting the newlines into 
the JSP file yourself. The only thing I can think of would be to have 
Tomcat ignore trailing whitespace on JSP source lines that nothing but a 
JSP directive or something like jsp:include...

You other option might be to create a filter that collapsed multiple 
consecutive newlines into a single one. This might break some of your 
page, though.

Even better! What version of IE are you using, BTW? I'm wondering if

Re: xhtml and Internet Explorer

2003-10-30 Thread Marius Scurtescu
I will consider implementing a filter to remove
the empty lines before the html tag.
For now I eliminated most of the empty lines by
changing:
[EMAIL PROTECTED] import=... %
[EMAIL PROTECTED] language=Java %
jsp:include page=foo.jsp /
jsp:include page=bar.jsp /
jsp:include page=baz.jsp /
to:

[EMAIL PROTECTED] import=... language=Java 
%jsp:include page=foo.jsp 
/jsp:include page=bar.jsp 
/jsp:include page=baz.jsp /

Ugly, but at least there is one directive per page.

It would be great if the JSP compiler would not output
new lines for lines containing only JSP directives. I
will fill a feature request for this.
I am using IE 6 SP1, so this issue is still not
fixed. Microsfot may not even be aware of it.

once it guessed the type of a page it is caching that
info in memory.


Even better! What version of IE are you using, BTW? I'm wondering if 
they've finally fixed this in IE 6.0. I still use 5.5 when I view a site 
that's so broken in Mozilla that I can't make sense of it (which makes 
me pretty much furious).

Ugly, but at least there is one directive per page.

It would be great if the JSP compiler would not output
new lines for lines containing only JSP directives. I
will fill a feature request for this.
I doubt you will get far with such a feature request. If you consider 
what the JSP is doing, you'll see it's only doing it's job. The new line 
is in the JSP!

It's nothing to do with the tag / page directive. Asking the tag or page 
directive not to output a new line afterwards is like asking it to scan 
ahead in the JSP to determine what comes next, and if it's a new line, 
please delete it.

Re: xhtml and Internet Explorer

2003-10-30 Thread Marius Scurtescu
JSP is a templating language which is using a meta
language: the JSP constructs.
The new line is in the JSP indeed, but is it part
of the meta language or part of the literal output?
I would argue that these new lines are part of the
meta language and that they should not be output.
You put them there so the meta language you use is
readable.
See how FreeMarker, another templating language,
is dealing with this issue:
http://freemarker.sourceforge.net/docs/dgui_misc_whitespace.html#dgui_misc_whitespace_stripping
You are not asking the directive to scan anything,
the page compiler could consider white space and newlines
after a directive as part of that directive.

xhtml and Internet Explorer

2003-10-29 Thread Marius Scurtescu
Hi,

I am using Tomcat 4.0.5 with JBoss 3.0.3 under
Win2K and I am trying to generate XHTML pages
with JSP.
Everything is fine with Mozilla, but IE keeps
showing the pages as raw XML.
I know that this issue came up before on this
list, but the solution suggested previously
(adding a page directive with the content type)
does not work.
I checked the headers sent by the server (using
LiveHTTPHeaders in Mozilla) and everything seems
to be OK. The content type is 
text/html; charset=UTF-8

The content generated by the JSP page is valid
XHTML. I saved it to a file and when loaded from
the file system it is rendered properly by IE.
Any clues?

Thanks,
Marius

Marius,
I am using Tomcat 4.0.5 with JBoss 3.0.3 under
Win2K and I am trying to generate XHTML pages
with JSP.
Everything is fine with Mozilla, but IE keeps
showing the pages as raw XML.
That's because IE ignores the Content-Type header and just looks at the 
first few bytes of the file to decide how to display it. What a POS. 
Anyway...

I know that this issue came up before on this
list, but the solution suggested previously
(adding a page directive with the content type)
does not work.
IE still ignores the Content-Type.

I checked the headers sent by the server (using
LiveHTTPHeaders in Mozilla) and everything seems
to be OK. The content type is text/html; charset=UTF-8
The content generated by the JSP page is valid
XHTML. I saved it to a file and when loaded from

What does the first line in your document look like? Do you have a 
!DOCTYPE in there, or do you start with an html header?

jsps xhtml and Internet Explorer

2003-08-14 Thread graham . stark
Hi there,
  anoyone know this one? 

I have a jsp page written to the xhtml standard. It looks like this:

?xml version=1.0?
 
!-- 
  - Author(s): 
  - Date:
  - Copyright Notice:
  - @(#)
  - Description:
  --
 jsp:root  xmlns:jsp=http://java.sun.com/JSP/Page;
xmlns:html=/WEB-INF/struts-html.tld
xmlns:bean=/WEB-INF/struts-bean.tld
xmlns:dt=http://jakarta.apache.org/taglibs/datetime-1.0;

version=1.2
html:html xhtml=true
head
   [...]
/head
body
   [...]
/body 
  /html:html
/jsp:root


All seems fine. The page compiles properly and looks nice on every browser I've
tried. Except Internet Explorer (v6), where it simply displays the XML source tree. 

I tried adding:

 mime-mapping
extensionjsp/extension
mime-typetext/html/mime-type
  /mime-mapping 

(and simlarly for xhtml) to the web.xml (both the webapp one and the global one).


I'm using tomcat 4.0.6 and java 1.4.1 (I can't easily upgrade these because this
is what my client use). I've had a search through the FAQs, this list's archive
and on Google and can't find the solution.

Has anyone seen this before? 

Many thanks,

Graham

Bill,
 many thanks: that worked perfectly.

 MSIE has a bad habit of ignoring Content-Type, so I don't know that this
 will work.  However, what you want is:
   jsp:directive.page contentType=text/html; charset=iso-8859-1 /
 
 (of course, change the charset if you aren't using iso-latin-1).
