OER Applet Error - A non-fatal error occurred when fetching an entity id

Question

Suddenly I have a problem when I want to run 'graphic representation of related items' applet from Oracle Enterprise Repository 11.1.1.2. Thinkmap console shows up wit following message:
Error: A non-fatal error occurred when fetching an entity id :  : Remote Error: Login required to view information.
Error: A non-fatal error occurred when loading entities :  : Remote Error: Login required to view information.
Error: cannot set initial center entity : java.lang.NullPointerException
I suspect it's some issue with JRE, since everything worked fine few weeks ago. I've also tried to downgrade to JRE 1.5, but I still get the same error. I've tured on debugging and in java console I get this:
Trace level set to 5: all ... completed.

Browse tree doesn't work either..message in Java console is:

Anybody has an idea what is wrong and how to resolve this problem.

Answer 1

I figured out what is causing this problem: When connecting OER with LDAP according to documentation (http://download.oracle.com/docs/cd/E15523_01/doc.1111/e16580/extauth.htm#CEGHHGAG ) you have to disable cookie login functionality. Now i figured that 'graphic representation of related items' and 'browse tree' applets are not working if there is no cookie for user. So in order for those two applets to work I have to enable enterprise.security.cookielogin.allow and enterprise.authentication.ldap.enabled (or manually check the Enable automatic Login box).
Is there any other setting or workaround that would ensure that mentioned applets would work properly without enable automatic login option checked?! And what is the problem if I do have LDAP authentication and cookie login enabled (why is explicitly stated in documentation that I should disable cookie login with LDAP authentication?) Can someone from Oracle clarify this please?
