    <p>Could you possibly explain how I can get the <code>ServletContext</code> instance in my <code>Application</code>'s sub-class? Is it possible? I have tried to do it like in the following snippet but it does not seem to work - the <code>ctx</code> is not set:</p> <pre><code>import javax.ws.rs.core.Application; import javax.ws.rs.core.Context; //... @ApplicationPath("/") public class MainApplication extends Application { @Context ServletContext ctx; @Override public Set&lt;Class&lt;?&gt;&gt; getClasses() { Set&lt;Class&lt;?&gt;&gt; classes = new HashSet&lt;Class&lt;?&gt;&gt;(); //... return classes; } } </code></pre> <p>web.xml:</p> <pre><code>&lt;web-app ...&gt; &lt;context-param&gt; &lt;param-name&gt;environment&lt;/param-name&gt; &lt;param-value&gt;development&lt;/param-value&gt; &lt;/context-param&gt; &lt;filter&gt; &lt;filter-name&gt;jersey-filter&lt;/filter-name&gt; &lt;filter-class&gt;org.glassfish.jersey.servlet.ServletContainer&lt;/filter-class&gt; &lt;init-param&gt; &lt;param-name&gt;javax.ws.rs.Application&lt;/param-name&gt; &lt;param-value&gt;my.MainApplication&lt;/param-value&gt; &lt;/init-param&gt; &lt;/filter&gt; ... &lt;/web-app&gt; </code></pre> <p>The problem is that I need to get context parameters from it. If there is another way, I would be grateful if somebody gave a hint.</p> <hr> <p>I understand that <code>Context</code> annotation might not be purposed for this. Actually, I do not need <code>ServletContext</code> itself. If only I could get context params from web.xml, I would be absolutely happy.</p> <p>Here is an example of what I really need:</p> <pre><code>import java.util.HashSet; import java.util.Set; import javax.servlet.ServletContext; import javax.ws.rs.core.Application; import javax.ws.rs.core.Context; import org.glassfish.hk2.utilities.binding.AbstractBinder; public class MainApplication extends Application { @Context ServletContext ctx; @Override public Set&lt;Object&gt; getSingletons() { Set&lt;Object&gt; set = new HashSet&lt;Object&gt;(); final String environment = ctx.getInitParameter("environment"); //final String environment = ... get context parameter from web xml set.add(new AbstractBinder() { @Override protected void configure() { bind(new BaseDataAccess(environment)).to(DataAccess.class); } }); //... return set; } } </code></pre> <p>Thanks.</p>

    3. CO@Buhb, this is not a duplicate. He's trying to access `ServletContext` from the `Application` whereas the other post is trying to access it from a `Resource`.

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).
