well that's the thing. Nothing has changed since it was working. The 
index.tmpl file is still where it was when everything was working 
(pre-mod_perl).

the complete error msg is

it seems the ModPerl:Registry is doing something funky here.

Then, later on the error msg says

> HTML::Template::new('HTML::Template','filename','index.tmpl','filter','C
> ODE(0xc9de7c)','cache',0) called at C:/htdocs/bims/index.cgi line 21

there is no msg there about the file not being found.

I must mention that the problem is simply because of mod_perl (at least 
the way I have it set up), because I uninstalled mod_perl, and 
everything works.

I know this is not the mod_perl list, but since HT works (better?) in 
conjunction with mod_perl, I am hoping to find some direction here.

Thanks,

and you are absolutely right !!!

thanks.

of course, now the problem is that all my paths are screwed up... for 
example, I have a stylesheet linked to index.tmpl (relative path)... 
that is no longer being picked up. I don't want to insert absolute paths 
to the templates and linked files (I move the projects around between 
the iBook and the Win2k boxes).

is there something I can do with the modperl::registry to get around 
this behavior?

in any case, thanks for quickly pointing out the error.

Puneet.

oh no... I spoke too soon... the problem was not with the path to the 
stylesheet (your diagnosis was still correct in solving the initial 
problem). But, it seems that moperl::registry is trying to parse and 
compile my stylesheet as well. The Apache error.log shows

yikes! what to do?

It looks like the template you are loading can't find one of it's included
files.  I can't be sure, but this might have to do with a change that was made
in ModPerl::Registry to make it tread safe.  ModPerl::Registry no longer chdir's
to the directory that your script resides in when it executes your script (this
is different from what mod_cgi CGI script does).  Since the perl interpreter is
shared between threads, you can't chdir to change the directory, because that
would affect all threads.

I am guessing that your didn't provide HTML::Template with a path option
pointing to your template directory, so it is looking in the current directory
for include files, and the current directory is not necesarily the same as the
script directory.

I would suggest you provide a path => '/path/to/include/files to HTML::Template
and see what happens then.

You are getting a bit off topic now for the HTML::Template mailing list.  You
have a mod_perl configuration problem, so the mod_perl mailing list would be a
better place to ask this.  see http://perl.apache.org for some great
documentation on mod_perl.

To get you on the right track, check out your apache configuration for
ModPerl::Registry.  If you followed the sample in the docs, then you setup a
directory like /perl where all your perl scripts go, and you configured
ModPerl::Registry to consider everything in that directory a perl script.

You probably have your template files, and css files all in that same directory.
   Which means modPerl::Registry parsing all those file expecting them to be
Perl scripts.

The easiest way to fix this is to change your ModPerl::Registry configuration to
use a <Files *.pl></Files> directive instead of a <Location /perl></Location>. 
That will look at the file name to decide whether it is a perl script instead of
the directory it is in.  A cleaner approach is to put your css files and
templates in a different directory.  my css files all go in /css and my template
files are always outside the document root of the web-server.

This is really a programming issue, not a mod_perl issue.  But you could use
mod_perl to solve your problem by setting a variable in your apache.conf file
that your scripts pick up.  An environment variable would do the trick.

SetEnv TEMPLATE_PATH '/path/to/templates'

then in your code use

$ENV{TEMPLATE_PATH}

Check the Apache docs on how to properly setup Environment variables because the
above might not be exactly right.  I think mod_perl also has a PerlEnv
directive, but I haven't used that stuff in a while.

ok thanks. I have enough info now to figure this out and set it right. 
Back to HT programming.

Thanks much for the direction.
