I think the problem that you are having is that the browser is caching the PDF file, and even though there is a new file available on the server, the browser is not fetching it. In order to force the browser to fetch the latest version of the PDF file you need to set the expiration header in the HTTP response to a very short time. More information for setting this up in Tomcat can be found <a href="http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/filters/ExpiresFilter.html" rel="nofollow">here</a>. I believe this is a feature only available since Tomcat 7. For previous versions of <code>Tomcat</code>, you need to roll your own <code>Servlet</code> that modifies the response header, which you can easily find with a bit of googling. To take a look at the actual HTTP response header, you can use the developer tool built into Chrome or Firebug with Firefox. Here's the relevant entry in web.xml that you will need: <pre><code> <filter> <filter-name>ExpiresFilter</filter-name> <filter-class>org.apache.catalina.filters.ExpiresFilter</filter-class> <init-param> <param-name>ExpiresByType application/pdf</param-name> <param-value>access plus 1 minutes</param-value> </init-param> </filter> <filter-mapping> <filter-name>ExpiresFilter</filter-name> <url-pattern>uploads/folder/*</url-pattern> <dispatcher>REQUEST</dispatcher> </filter-mapping> </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
