    <p>I realize this is old but since the answers provided don't really answer the question, for future reference you can achieve multiple <code>WebappContext</code>s using the same .war by adding an <code>id</code> attribute to <code>Configure</code>.</p> <pre><code>&lt;Configure id="magazinesContext" class="org.eclipse.jetty.webapp.WebAppContext"&gt; &lt;Set name="contextPath"&gt;/magazines&lt;/Set&gt; &lt;Set name="war"&gt;&lt;SystemProperty name="jetty.home" default="."/&gt;/webapps/bookstore.war&lt;/Set&gt; &lt;Set name="extractWAR"&gt;true&lt;/Set&gt; &lt;/Configure&gt; &lt;Configure id="booksContext" class="org.eclipse.jetty.webapp.WebAppContext"&gt; &lt;Set name="contextPath"&gt;/books&lt;/Set&gt; &lt;Set name="war"&gt;&lt;SystemProperty name="jetty.home" default="."/&gt;/webapps/bookstore.war&lt;/Set&gt; &lt;Set name="extractWAR"&gt;true&lt;/Set&gt; &lt;/Configure&gt; </code></pre> <p>Note however that all naming Resources defined in the context must be either assigned to the context using </p> <pre><code>&lt;Arg&gt; &lt;Ref id="magazinesContext" /&gt; &lt;/Arg&gt; </code></pre> <p>So if you have dbcp pooling resource "pg_conn", without the Arg with the reference to the id of the <code>WebappContext</code> (in this case either "magazinesContext" or "booksContext") the Resource will be globally defined, ie the last WebAppContext loaded wins. </p> <p>Take for example the following <code>WebappContext</code> definition where "pg_conn" is globally defined:</p> <pre><code>&lt;Configure id="magazinesContext" class="org.eclipse.jetty.webapp.WebAppContext"&gt; &lt;Set name="contextPath"&gt;/magazines&lt;/Set&gt; &lt;Set name="war"&gt;&lt;SystemProperty name="jetty.home" default="."/&gt;/webapps/bookstore.war&lt;/Set&gt; &lt;Set name="extractWAR"&gt;true&lt;/Set&gt; &lt;New id="pg_conn" class="org.mortbay.jetty.plus.naming.Resource"&gt; &lt;Arg&gt;jdbc/db&lt;/Arg&gt; &lt;Arg&gt; &lt;New class="org.apache.commons.dbcp.BasicDataSource"&gt; &lt;Set name="driverClassName"&gt;org.postgresql.Driver&lt;/Set&gt; &lt;Set name="url"&gt;jdbc:postgresql://localhost:5432/test_db&lt;/Set&gt; &lt;Set name="username"&gt;test&lt;/Set&gt; &lt;Set name="password"&gt;*****&lt;/Set&gt; &lt;/New&gt; &lt;/Arg&gt; &lt;/New&gt; &lt;/Configure&gt; </code></pre> <p>and this one, where it is defined for the instance of <code>WebappContext</code>:</p> <pre><code>&lt;Configure id="magazinesContext" class="org.eclipse.jetty.webapp.WebAppContext"&gt; &lt;Set name="contextPath"&gt;/magazines&lt;/Set&gt; &lt;Set name="war"&gt;&lt;SystemProperty name="jetty.home" default="."/&gt;/webapps/bookstore.war&lt;/Set&gt; &lt;Set name="extractWAR"&gt;true&lt;/Set&gt; &lt;New id="pg_conn" class="org.mortbay.jetty.plus.naming.Resource"&gt; &lt;Arg&gt; &lt;Ref id="magazinesContext" /&gt; &lt;/Arg&gt; &lt;Arg&gt;jdbc/db&lt;/Arg&gt; &lt;Arg&gt; &lt;New class="org.apache.commons.dbcp.BasicDataSource"&gt; &lt;Set name="driverClassName"&gt;org.postgresql.Driver&lt;/Set&gt; &lt;Set name="url"&gt;jdbc:postgresql://localhost:5432/test_db&lt;/Set&gt; &lt;Set name="username"&gt;test&lt;/Set&gt; &lt;Set name="password"&gt;*****&lt;/Set&gt; &lt;/New&gt; &lt;/Arg&gt; &lt;/New&gt; &lt;/Configure&gt; </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.

SQuiL has stopped working due to an internal error.

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