Re: Mod-jk worker not being called after calling Perl handler

Finally I have something that seems to work. I could find only this
way of calling mod-jk after perlhandler gets called. Does it look ok?

In <VirtualHost ..

PerlModule Apache2::Rules2
SetHandler modperl
PerlHandler Apache2::Rules2
JkMount ...

----

package Apache2::Rules2;
#use lib '/home/.mohit/mod_perl-2.0.4/lib';
use strict;
use warnings;
use Apache2::Const qw(:common);
use Apache2::RequestRec ();
use Apache2::RequestIO ();
use Apache2::Filter ();
use APR::Table ();


sub handler {
my $r = shift;
my $headers_in = $r->headers_in();
if ($headers_in->get("Content-Length") < 20){
   $r->handler("jakarta-servlet");
   return DECLINED;
}

#$r->content_type('text/plain');
#$r->print('Rules');

return OK; # We must return a status to mod_perl
}
1; # This is a perl module so we must return true to perl
