Suddenly I get "java.lang.nullpointer exception"

Hello all!!

I have been running a OpenKM 5.1.9 installation for several weeks now without issues. However, as of yesterday, I am all the sudden getting "java.lang.nullpointer exception" when anyone tries to log in.

See the attachment a screenshot of what I am getting. This happens immediately after clicking the "login" button. I changed the logo obviously.

Here is the error log , and a few lines before the error

I have tried restarting the server, clearing the jboss/OKM cache's etc, still no luck.

I think it has something to do with the repository, as I created a new test installation, it works fine until I copy over my non-working repository. Then I get the same error.

Nothing has been changed in the installation, or in OKM itself as it was working fine Friday, when we came back to work from the weekend it was throwing this exception.


Any help is VERY MUCH appreciated.

Thank You!!!!

Looks like the repository was tampered!! did you check the repository.xml?...The best bet is to export all files and re-install1

Take I look you're starting stopping jboss application correctly ( seems could not be really stopped and you turn to start againg, that could be the cause of repository node locked ).

Take a look you really have jboss stoped before starting other.
