    <p>One way to do it would be with Filters. You'd have to write a little bit of custom code but it's not bad. Here's an example if you don't want to pass *.css or *.js files to your Spring servlet:</p> <p>web.xml:</p> <pre><code>&lt;filter-mapping&gt; &lt;filter-name&gt;fileTypeFilter&lt;/filter-name&gt; &lt;filter-class&gt;foo.FileTypeFilter&lt;/filter-class&gt; &lt;url-pattern&gt;/*&lt;/url-pattern&gt; &lt;/filter-mapping&gt; </code></pre> <p>Java class:</p> <pre><code>public class FileTypeFilter implements Filter { public void init(FilterConfig conf) { // init logic here } public void destroy() { // release resources here } public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws ServletException, IOException { if(shouldExclude(req)) { chain.doFilter(req, res); //some logic so the request doesnt go to the servlet //maybe you could just forward //the request directly to the file getting accessed. not sure if that would work } //file should be passed to the servlet; you can do some logic here //if you want } private boolean shouldExclude(ServletRequest req) { if(req instanceof HttpServletRequest) { HttpServletRequest hreq = (HttpServletRequest) req; return (hreq.getRequestURI().endsWith(".css") || hreq.getRequestURI().endsWith(".js")); } return false; } } </code></pre> <p>I haven't tested this, but I think it will work.</p> <p><strong>EDIT</strong>: There's isn't any exclude functionality in the servlet spec. I don't think there is a good way to do this within Spring, but it essentially achieves the same thing in your post.</p> <p><strong>EDIT 2</strong>: If you want to be able to easily change what gets filtered, you could just use Spring to inject something into the Filter at runtime. </p> <p><strong>EDIT 3</strong>: I just realized if you forward directly to the file, it'll do the filter again and you'll get caught in an infinite loop. There might be another way to do this with filters, but I'm honestly not sure what it is.</p>

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.
