Re: Error matching patterns problem

Alexander,

It seems to occur in the Perl5Matcher.matches() method from the Jakarta-ORO
regular expression library when it tries to match the form-login-page or
form-error-page patterns. Your login and error page patterns look fine to
me, so I am not sure what is going wrong.

I don't see any reason why you should need to, but perhaps renaming the
login and error pages would help us determine what is going wrong. The
example app that I have done the most testing with uses these names (which
seem very similar to yours, so I don't see why there would be a problem):

      <form-login-config>
         <form-login-page>/loginForm.jsp</form-login-page>
         <form-error-page>/loginError.jsp</form-error-page>
         <form-default-page>/index.jsp</form-default-page>
      </form-login-config>

Does it do this for any request? If not, could you send us a URI that leads
to the error.
