11:11:56,531 WARN [FormAuthenticator] Unexpected error forwarding to login page
java.lang.NullPointerException
at org.apache.jasper.runtime.TagHandlerPool.get(TagHandlerPool.java:108)

After deployment of a war, when i try to access a JSP page, the above error occur. Any idea what is the cause? What configuration should i set?

It appears that you have security settings for your web application and that you are using form-based authentication. Is the login page available? Also check for typos on the login page name.

I assume this as a precompile issue with and jspc, use tomcat jspc insted.
