Forum Problems Installing LAMS: Re: Re: Re: problems integrating Moodle 1.83 and LAMS 2.04 on Windows 2003

We are trying to track this one down.

If you try copying and pasting the URL in the error message straight into your browser, does it throw any errors. You have to get the exact URL or it will fail validation checks.

Also, are there any errors in the logs in [jboss]/server/default/log? Particularly in lams.log and server.log?

We made a change in the Moodle module to do with that area of the code last October, so we are wondering if that has something to do with it. Did you do the XP installation before or after the Windows 2003 version? Did you use the same copy of the module on both the XP and Windows 2003 servers or did you download it a second time?

I assume both machines have the same country and language settings?

Thanks for the reply.

The apache tomcat returned Http Status 400 - Cannot retrieve user information when i paste the url into the browser.

And as for the log, it's giving the error as below in Lams.log

15:42:33,859 [http-0.0.0.0-8080-1:] ERROR org.lamsfoundation.lams.web.session.SessionManager - Failed on finding current system session with null sessionId

The installation is carried out in 2 different machine. Since the installtion in windows 2003 failed so I tried it on my XP machine. And both machines are having the same language settings.

Both are using php 5.2 and using the same copy of module.

If there aren't any errors on the LAMS logs then it points to an error on the Moodle side, or in the URL that calls Moodle to get the user details.

In LAMS, log in as sysadmin and go to the Sys Admin menu, the Maintain Integrated Servers screen and edit the Moodle configuration. Find the entry for the User Information URL and copy and paste that URL into your browser. That will try to call Moodle to get the user details. Does that work?

The url will be something like:

http://<moodle_server>/mod/lamstwo/userinfo.php?ts=%timestamp%&un=%username%&hs=%hash%

or

http://<moodle_server>/moodle/mod/lamstwo/userinfo.php?ts=%timestamp%&un=%username%&hs=%hash%

The extra "moodle/" is needed if you call access Moodle as http://<moodle_server>/moodle/ - it depends on how you installed Moodle.

If the url fails, and adding/removing the "/moodle" isn't the solution, then have a look at the Apache logs for any errors that Moodle might be writing out.

Tried it out by still no luck with it. Checked Apache log and there is no error. Any other idea...?

I assume both Moodle and LAMS are on the same box?

Are you referring them as "localhost", via an IP address, via a name? If it is localhost, is localhost defined in the hosts file (I can't remember if Windows 2003 might need localhost defined or not).

This sounds like a silly question, because if you are referring to LAMS and Moodle using localhost, and localhost wasn't defined, then Moodle wouldn't be getting through to LAMS at all. But I'm clutching at straws here.

Of course this is for IE, by default Firefox doesn't block 3rd party cookies I think...
