help with moving realm to 5.0

[joelsherriff <jo...@comcast.net>]

Background:  I had a blojsom blog server set up on tomcat 4.1 that used a jdbc realm to control access.  I customized the login.jsp to
include some local .gifs and such that aren't part of the blojsom.war file (I don't want to modify the 3rd party .war file unless I absolutely
have to) and originally had problems getting the images to appear.  I found that the reason the images wouldn't appear is that because
they were under the webapps/blojsom directory, they were also restricted by the realm access.  So that attempting to access them invoked
the realm security control.  So I had a chicken and egg problem with allowing access to the images.  I finally solved that by modifying
the webapp's web.xml file and changing the <url-pattern> within the <security-contraint> to be "/blog/*", instead of just "*" so that only
attempts to access the individual's blogs would be controlled.

That worked fine for 4.1.

But, now I've upgraded to 5.0.30 and it no longer works, I'm back to having no images, external to the war file, being displayed by my login.jsp.
Everything has been copied from the 4.1 config to the 5.0 config.  Is there something I forgot to do?  The log file shows that when it is
attempting to access one of the image files, which should be /blojsom/images/logo.gif, the actual filename it's requesting in the GET is
/blojsom/blog/images/logo.gif, which is wrong.

For example, this is taken from the 4.1 log:

2005-05-10 18:25:12 Authenticator[/blojsom]: Security checking request GET /blojsom/images/logo.gif

and this is taken from the 5.0 log:

Security checking request GET /blojsom/blog/images/logo.gif
