Can not log in

Which MySQL version are you using? Also, it appears that there is more than one connector/j jar in the web application.

Please look at WEB-INF/lib and your Tomcat's common/lib directory.

I seem to be unable to log in to my own jforums. The error I get is:

Oct 15 00:02:31 ERROR ExceptionWriter

java.lang.NullPointerException
at net.jforum.view.forum.UserAction.validateLogin(UserAction.java:410)
at net.jforum.view.forum.UserAction.validateLogin(UserAction.java:428)

at javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

Any thoughts would be appreciated.

Thanks.

Note: I briefly enabled the SSO, and then commented that out. I haven't been able to log in since. Perhaps something in the DB still thinks I'm using SSO?

Further info: trying to log on after awhile just gives me this:
My DB settings are correct. I can connect with the username/password using mysql ...

If I reinstall will jforums keep and use the existing database info?

An error has occurred.

For detailed error information, please see the HTML source code, and contact the forum Administrator.

MySQL 4.1.20
Java 1.5.0_08

I found the duplicate jforum/WEB-INF/lib/mysql*jar and removed it. The same one exists in tomcat/common/lib.

Is there anything else you'd suggest I'd look at?

It was working fine for several weeks, then I changed the DB timeouts, and it hasn't worked since even though I changed the timeouts back.

My MySql timeouts are 300 seconds.
The jforum timeouts are 5000. I don't know if that is seconds or not. It must be shorter than the MySQL timeout. I changed the value to 200 just in case it is seconds but that didn't help.

I went through the 'forgot password' process, and that worked right up to the point where I log in, then the password is not valid.

Thanks for any suggestions.

Cheers.
