    <p>I have a Servlet 3.0 web app that uses both Spring and Jersey. I currently have it set up using the SpringServlet configured as a filter in web.xml, and the resource classes annotated with both <code>@Path</code> and <code>@Component</code>. Here's the web.xml snippet:</p> <pre><code>&lt;filter&gt; &lt;filter-name&gt;jersey-serlvet&lt;/filter-name&gt; &lt;filter-class&gt; com.sun.jersey.spi.spring.container.servlet.SpringServlet &lt;/filter-class&gt; &lt;init-param&gt; &lt;param-name&gt; com.sun.jersey.config.property.packages &lt;/param-name&gt; &lt;param-value&gt;com.foo;com.bar&lt;/param-value&gt; &lt;/init-param&gt; &lt;init-param&gt; &lt;param-name&gt;com.sun.jersey.config.feature.FilterForwardOn404&lt;/param-name&gt; &lt;param-value&gt;true&lt;/param-value&gt; &lt;/init-param&gt; &lt;/filter&gt; &lt;filter-mapping&gt; &lt;filter-name&gt;jersey-serlvet&lt;/filter-name&gt; &lt;url-pattern&gt;/*&lt;/url-pattern&gt; &lt;/filter-mapping&gt; </code></pre> <p>This setup works, but I really want to get this set up with annotations only - no web.xml config. My first attempt at this was to remove the above SpringServlet configuration and create a class that extends <code>Application</code>. Here's a snippet of that:</p> <pre><code>@ApplicationPath("/*") public class MyApplication extends PackagesResourceConfig { public MyApplication() { super("com.foo;com.bar"); HashMap&lt;String, Object&gt; settings = new HashMap&lt;String, Object&gt;(1); settings.put(ServletContainer.FEATURE_FILTER_FORWARD_ON_404, true); this.setPropertiesAndFeatures(settings); } } </code></pre> <p>This works in that the JAX-RS resources are registered and I can hit them at their URLs, but they throw NullPointerExceptions when they try and use their autowired properties... this makes sense because I'm guessing the resources are now being loaded by Jersey and are not Spring managed beans, therefore no autowiring. </p> <p>Despite a fair bit of searching around I cannot find any way of loading the Jersey resources as Spring beans with annotations only. <b>Is there such a way?</b> I don't really want to have to write a bunch of code for the resources to manually fetch the Spring context and invoke the DI if I can help it.</p> <p>If annotations-only isn't going to work, then I can live with the filter config in web.xml if I can specify an <code>Application</code> class to load instead of a list of packages to scan. If I can get rid of the package list in there and just specify an <code>Application</code> class instance then I'll be content.</p> <p>Obviously it would be great if someone had a definitive answer for me but I'd also be grateful for any pointers or hints of where else I could look or things to try.</p> <p>Thanks, Matt</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.
