    <p>I always think that you should be able to make exceptions to url-patterns in a web.xml e.g. if you could do something like this:</p> <pre><code>&lt;filter-mapping&gt; &lt;filter-name&gt;MyFilter&lt;/filter-name&gt; &lt;url-pattern&gt; &lt;match&gt;/resources/*&lt;/match&gt; &lt;except&gt;/resouces/images/blah.jpg&lt;/except&gt; &lt;/url-pattern&gt; </code></pre> <p>but you can't so that's no help to you!</p> <p>You obviously have access to the URL in the Filter through the request object so you could do something like this:</p> <pre><code>public void doFilter(ServletRequest sRequest, ServletResponse sResponse, FilterChain chain) throws IOException, ServletException { HttpServletRequest request = (HttpServletRequest)sRequest; if(!request.getRequestURI.equals("/resources/images/blah.jpg")) { doLogging(); } chain.doFilter(); } </code></pre> <p>(hard-coded here but you'd probably read it from a property file) although this may not be of use to you as you mentioned servlets in your query as opposed to URL patterns.</p> <p>EDIT: another thought. If you don't mind doing your logging after the servlet has completed you could do something like this:</p> <pre><code>public void doFilter(ServletRequest sRequest, ServletResponse sResponse, FilterChain chain) throws IOException, ServletException { sRequest.setAttribute("DO_LOGGING", new Boolean(true)); chain.doFilter(); Boolean doLogging = (Boolean)sRequest.getAttribute("DO_LOGGING"); if(doLogging) { doLogging(); } } </code></pre> <p>and your servlet that you want to exclude from logging can just set that attribute to false.</p> <pre><code>public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException { req.setAttribute("DO_LOGGING", new Boolean(false)); // other stuff } </code></pre>

Guidance
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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
