Yup, done that and I managed to login but it displays the HTTP500 error page instead.

Should I proceed to do a reinstall? Can't figure out what could be the problem here.

Do you get the same if you restart lams?

Yup, do get the same error when i restart LAMS and JBOSS.

After restarting, I managed to get to the login page and enter the uname and pwd but it than directs me to this HTTP500 page.

Seems to be having a null session id and not matching to the current session id, but I'm unsure where to make changes.

Yeah, not sure what's happening there - do you have the logs for the installer? They should be located under lams-unix-installer-2.0.4/log/.

Aplogises .. it seems like its working now ... managed to login successfully, but seem like there another problem accessing the sysadmin function. Thanks for assisting all this while.

The user object containing some info about the logged-in user is missing... are you logged into a Wildfire admin interface by any chance? That can interfere with LAMS' cookies. Try closing the browser and all it's windows and logging in again, starting a fresh new session. If you still get the 'userDTO is missing' message, something deeper must still be wrong.

I did not install Wildfire as I have decided not to have a chat function. Did close all the browser windows and clear its cache.

Now it shows me the HTTP404 error, previous it just open a new window with the same information.

Any chance where I should look at?

Just had a closer look at the conf files in 2.0.4, and there's one more thing I think you might not have done - in /path/to/jboss-4.0.2/server/default/conf/lamsauthentication.xml, at the top is another @confdir@ which needs to contain the proper path to lamsauthentication.dtd (should be in the same directory).

Should the top part look like this?

How many slashes should it have?

Posted by Martyn Yap

By: Jun-Dir Liew

[ Reply | Forward ]

The first two lines should look like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Authentication PUBLIC "-//LAMS//DTD LAMS//EN" "http://lamsfoundation.org/dtd/lamsauthentication.dtd">

This version points to the lamsfoundation.org website, which should also work.

Tried both the ways and the same problem still occurs?

Now it seems that I do not get a HTTP 404 error but the page keeps on refreshing itself.

Thanks! =]

Can you reinstall the installer from scratch? Originally your install had an error where it didn't copy the files across, and we never got to see the logs as to why that happened. Before installing though, remove the current jboss-4.0.2 directory, unzip a new jboss-4.0.2 instance, drop the current lams database, and then run the installer again - if you run into problems, post the installer logs (located under lams-unix-installer-2.0.4/logs).

Hihi,

It works after removing the JBOSS directory and dropping the database. Not sure where it went wrong but sincere thanks for the assistance given.

Now ... I'm going to try to integrate LAMS with Blackboard.

Cheers!
