    <p>The title is pretty self-explanatory. When I run my app on Netbeans (Tomcat 7), everything works fine (the root index.jsp file from my dir structure is shown in the browser):</p> <p><img src="https://i.stack.imgur.com/Z6JvY.png" alt="enter image description here"></p> <p>When I deploy the app to my production server, it deploys successfully:</p> <p><img src="https://i.stack.imgur.com/Dyrfc.png" alt="enter image description here"></p> <p>however, when I try to access the page in the production server, it only shows me a blank page and not the index.jsp file:</p> <p><img src="https://i.stack.imgur.com/1Vf0D.png" alt="enter image description here"></p> <p>Here is my web.xml file for this app:</p> <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"&gt; &lt;filter&gt; &lt;filter-name&gt;filter&lt;/filter-name&gt; &lt;filter-class&gt;com.dendro.mvc.filters.StaticFilesFilter&lt;/filter-class&gt; &lt;/filter&gt; &lt;filter-mapping&gt; &lt;filter-name&gt;filter&lt;/filter-name&gt; &lt;url-pattern&gt;/*&lt;/url-pattern&gt; &lt;/filter-mapping&gt; &lt;!-- abstract controller to filter static file requests --&gt; &lt;servlet&gt; &lt;servlet-name&gt;Controller&lt;/servlet-name&gt; &lt;servlet-class&gt;com.dendro.mvc.filters.Controller&lt;/servlet-class&gt; &lt;/servlet&gt; &lt;!-- servlet names --&gt; &lt;servlet&gt; &lt;servlet-name&gt;PropagatedResults&lt;/servlet-name&gt; &lt;servlet-class&gt;com.dendro.query.PropagatedResultsServlet&lt;/servlet-class&gt; &lt;/servlet&gt; &lt;servlet&gt; &lt;servlet-name&gt;PlainResults&lt;/servlet-name&gt; &lt;servlet-class&gt;com.dendro.query.PlainResultsServlet&lt;/servlet-class&gt; &lt;/servlet&gt; &lt;servlet&gt; &lt;servlet-name&gt;HomeFilter&lt;/servlet-name&gt; &lt;servlet-class&gt;com.dendro.query.HomeFilterServlet&lt;/servlet-class&gt; &lt;/servlet&gt; &lt;!-- mappings --&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;Controller&lt;/servlet-name&gt; &lt;url-pattern&gt;/views/*&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;HomeFilter&lt;/servlet-name&gt; &lt;url-pattern&gt;/views/&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;PlainResults&lt;/servlet-name&gt; &lt;url-pattern&gt;/views/query/plain_results&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; &lt;servlet-mapping&gt; &lt;servlet-name&gt;PropagatedResults&lt;/servlet-name&gt; &lt;url-pattern&gt;/views/query/propagated_results&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; &lt;session-config&gt; &lt;session-timeout&gt; 30 &lt;/session-timeout&gt; &lt;/session-config&gt; &lt;welcome-file-list&gt; &lt;welcome-file&gt;index.jsp&lt;/welcome-file&gt; &lt;/welcome-file-list&gt; </code></pre> <p></p> <p>And my context.xml file:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;Context antiJARLocking="true" path=""/&gt; </code></pre> <p>The tomcat logs only show me successful requests (200 ok):</p> <pre><code>192.168.5.77 - - [23/Jun/2012:14:00:29 +0100] "GET /GraphQuery-1.0-SNAPSHOT/ HTTP/1.1" 200 - 192.168.5.77 - - [23/Jun/2012:14:00:29 +0100] "GET /GraphQuery-1.0-SNAPSHOT/ HTTP/1.1" 200 - 192.168.5.77 - - [23/Jun/2012:14:00:30 +0100] "GET /GraphQuery-1.0-SNAPSHOT/ HTTP/1.1" 200 - 192.168.5.77 - - [23/Jun/2012:14:00:31 +0100] "GET /GraphQuery-1.0-SNAPSHOT/ HTTP/1.1" 200 - </code></pre>

    2. COThere is the catalina.out, localhost.<date>.log files and the localhost_access_log<date> files. None of them show any deployment errors. I think this is related to the context.xml file, maybe it is not redirecting to the correct root... I have tried to change the path attribute of the Context element (in the context.xml file) to /GraphQuery-1.0-SNAPSHOT, to no avail...

    3. CODo they show anything else? Tomcat might have become confused.

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).
