Metacat

I did get a lot farther with the rc7 source distribution. I was able to install it on linux and get through the configuration dialogs okay. This time the database configuration correctly identified the metacat version as 1.8.0 (well, almost correctly, since the actual version was 1.8.1) and succeeded in upgrading the database to version 1.9.0.

I installed and tested the 'default' skin. The simple search form seems to work well, and so do the browse terms. However, the default skin's Advanced Search form appears to be broken. There is a problem with the wrong metacat URL being specified. Notice in the following error message how the 'knb' context is missing from the URL. Instead of:

http://scoria.lternet.edu:8080//metacat

the correct URL should have been:

http://scoria.lternet.edu:8080/knb/metacat

Here is the full error message from the Tomcat logs:

To reproduce this problem, install the 'default' skin, click on the 'Advanced Search' link, and try any type of advanced search.

I originally developed the Advanced Search code, but I haven't had a chance yet to look at what is causing the bug in the metacat URL.
