    <p>I'm using JUnit test cases to exercise my web service using embedded Tomcat. Under Tomcat 6 everything was working fine, but when I switched my project to Tomcat 7 I'm coming unstuck.</p> <p>The test code to setup the embedded Tomcat server is as follows:</p> <h3>Tomcat 6</h3> <pre><code>Embedded container = new Embedded(); container.setCatalinaHome("C:\\Program Files\\Apache Software Foundation\\Tomcat 7.0.11"); container.setRealm(new MemoryRealm()); container.setName("Catalina"); Engine engine = container.createEngine(); container.addEngine(engine); Host host = container.createHost("localhost", "/DecoderServiceTest"); Context rootContext = container.createContext("/DecoderServiceTest", System.getProperty("user.dir") + "/build/web"); host.addChild(rootContext); engine.setName("Catalina"); engine.addChild(host); engine.setDefaultHost("localhost"); container.addEngine(engine); Connector connector = container.createConnector(InetAddress.getLocalHost(), 4321, false); container.addConnector(connector); container.start(); </code></pre> <p>As the embedded API has changed between versions 6 and 7, I've changed my own code to the following:</p> <h3>Tomcat 7</h3> <pre><code>Tomcat tomcat = new Tomcat(); tomcat.setBaseDir("C:\\Program Files\\Apache Software Foundation\\Tomcat 7.0.11"); tomcat.setPort(1234); tomcat.addWebApp("/DecoderServiceTest", System.getProperty("user.dir")+"/build/web"); tomcat.setHostname("localhost"); tomcat.start(); </code></pre> <p>The actual web service starts up fine when I execute the JUnit test (I can use my web browser and see the WSDL being served up).</p> <p>However, in the constructor of my web service I intialise some variables based on the values in the <code>web.xml</code> file (which is located in <code>System.getProperty("user.dir")+"/build/web/WEB-INF/web.xml"</code>), as follows:</p> <pre><code> Context initCtx = new InitialContext(); Context envCtx = (Context) initCtx.lookup("java:comp/env"); int thumbnailSize = (Integer) envCtx.lookup("thumbnail-pixel-size"); </code></pre> <p>Where my <code>web.xml</code> file contains the following entry:</p> <pre><code>&lt;env-entry&gt; &lt;env-entry-name&gt;thumbnail-pixel-size&lt;/env-entry-name&gt; &lt;env-entry-type&gt;java.lang.Integer&lt;/env-entry-type&gt; &lt;env-entry-value&gt;64&lt;/env-entry-value&gt; &lt;/env-entry&gt; </code></pre> <p>When I try and create the <code>envCtx</code> object I get a <a href="http://download.oracle.com/javase/1.5.0/docs/api/javax/naming/NamingException.html" rel="nofollow">NamingException</a> with the message that <code>Name java:comp is not bound in this Context</code>. I'm confused because it worked fine with Tomcat 6. Have I missed something in the setup of Tomcat 7 that I had previously defined in the setup of Tomcat 6?</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.
