Are you using an older build? LAMS 1.0.2-20051019 had this error with integrations, you can check your version in the bottom right hand corner of the index page after you login.

The file in particular that changed after this version is $JBOSS_HOME/server/default/lib/lams-valve.jar, the old version has a byte size of 3307, while the updated version has a size of 3385.

You may also get this error if you manually enter a j_security_check URL into the browser (something like lamsserver.com/lams/j_security_check).

I'm using LAMS from within Moodle and I cannot see the version number, although I assume it is an old one because I think our administrator has used the same file she downloaded to install LAMS in our old server.

I also see this problem on a brand new LAMS install, though integrated with Blackboard. LAMS, 1.0.2 Build 20060424. Seems to effect sequences opened in a frame, if I open in a new window first, it works.

Hi Josep and Danny,

Another reason you might be getting a 400 error is if your browser is blocking 3rd party cookies. In this case LAMS is the 3rd party cookie when you're using it via Blackboard/Moodle.

In Firefox, blocking 3rd party cookies isn't enabled by default (you have to actively check the box 'for the originating site only' in the cookies options), but the default setting in IE blocks some, so try changing the setting or specifically allow your LAMS server's cookies through by adding it's domain to the list of allowable cookies and see if you still have the problem.
