[Google-Gadgets-API] Does gadget in sites know who the user is ?
Hi -
I am working in a setting where Google Sites is accessed via Single
Sign On. Because of this,
it is awkward and inconvenient for the gadget to request a second
login. I was wondering
how a gadget embedded in a Sites page can figure out what the user's
id might be ? Any way
for the Gadget to get access to any of the SAML attributes used to
provide the login ?

Re: Install problem - Infinite redirect detected...
So - let me see if I unbderstand fully what you're advising. I remove
reference to jsdk.jar or servlet.jar from build-turbine.sh, and it won't
build. I remove references from these two files from tomcat.sh, and tomcat
won't start. I'm a little confused here.

Re: Install problem - Infinite redirect detected...
Well, I did exactly this - I downloaded jsdk2.0 and I put it ahead of
servlet.jar in my tomcat.sh where it establishes the classpaths. After
that, no servlets ran at all - I get a null pointer exception. So then I
put it after servlet.jar, and I'm back to the infinate redirection
exception. Is there something I'm missing ?

Re: Install problem - Infinite redirect detected...
Do you know where I might go to get the 2.0 version of jsdk.jar ? - George >At 09:56 AM 4/25/00 -0400, you wrote: >>Thanks for answering. Unfortunately, that didn't fix it.

Re: Install problem - Infinite redirect detected...
Thanks for answering. Unfortunately, that didn't fix it. One thing I'm
wondering - when I built it, for the JSDK= argument, I used servlet.jar
rather than /JSDK2.0/jsdk.jar because that's the current version of that
library. Do you think that could have anything to do with it ?

Re: Embperl - where are the cookies ? Success....
Hi Everybody -
Finally got it working, and I wanted to sum up what I did so if somebody
else runs into this, it'll be waiting for 'em in the archives.
In the startup.pl, here's what I got:
BEGIN{
$ENV{EMBPERL_SESSION_CLASSES} = "DBIStore SysVSemaphoreLocker";
$ENV{EMBPERL_SESSION_ARGS}= "DataSource=dbi:mysql:gpp8p_casenet
UserName=gpp
8p Password=x";
}
use Apache::Session::Embperl;
use HTML::Embperl;
$Apache::Session::SysVSemaphoreLocker::nsems = 16;
(note - I'm running Solaris so I gotta have the nsems argument)
The table:
mysql> describe sessions;
+---+-+--+-+-+---+
| Field | Type| Null | Key | Default | Extra |
+---+-+--+-+-+---+
| id| varchar(16) | | PRI | | |
| expires | int(11) | YES | | NULL| |
| length| int(11) | YES | | NULL| |
| a_session | text| YES | | NULL| |
+---+-+--+-+-+---+
The test script:
Test of session features
[+ if($udat{counter} == 0){$udat{counter} = 1} +]
The page is requested [+ $udat{counter}++ +] occasions
since [+ $udat{date} ||= localtime +]
cookies: [+ $ENV{HTTP_COOKIE} +]
I think that covers it. Thanks for your help.

Re: Embperl - where are the cookies ?
Hi Owen -
Thanks for your response, but no cigar, unfortunately. Here's what I got:
# set env vars for embedded perl
BEGIN{
$ENV{EMBPERL_SESSION_CLASSES} = "DBIStore SysVSemaphoreLocker";
$ENV{EMBPERL_SESSION_ARGS}= "DataSource=dbi:mysql:gpp8p_casenet
UserName=gpp
8p Password=\!\!gpp8p";
}
use Apache::Session;
use HTML::Embperl;
I tried it with the braces surrounding the whole thing - same result.
Perhaps I don't have the tables set up right in MySQL - do you know where
this is described ?
here's what I got:
mysql> describe sessions
-> ;
+---+-+--+-+-+---+
| Field | Type| Null | Key | Default | Extra |
+---+-+--+-+-+---+
| id| varchar(16) | | PRI | | |
| expires | int(11) | YES | | NULL| |
| length| int(11) | YES | | NULL| |
| a_session | text| YES | | NULL| |
+---+-+--+-+-+---+

Using JSSI withj other servlet engines
Hi Everybody -
Does anybody have any experience with using ApacheJSSI with other
servlet engines - particularly servletexec? In particular, I'm interested
in the url re-writing feature - it appears that the querystring is somewhat
different under servletexec than it is under JServe, and I was wondering if
there is any way to accomodate this.

Error initializing protocol wrapper
Hi Everybody -
I configured ApacheJServ-1.0b4 to work with Apache v1.3 - configuration and makes
went through Ok - used GMAKE. When I run httpd I get the following in my
mod_jserv.log (and, of course, Apache won't come up):
[20/05/1999 14:28:08:190] (EMERGENCY) Error initializing protocols
[20/05/1999 14:28:52:122] (ERROR) an error returned initializing protocol "wrapp

ror
[20/05/1999 14:28:52:125] (EMERGENCY) Error initializing protocols

The Apache error_log says:
[Thu May 20 14:28:52 1999] [crit] (2)No such file or directory: Apache JServ enc
ountered a fatal error; check your ApJServLogFile for details if none are presen

Anybody ever encounter this ??
