    <p>How do you inject EJBs in Struts 2 actions? Are you using CDI? Are you using the <a href="http://www.mailinglistarchive.com/html/dev@struts.apache.org/2009-12/msg00024.html" rel="nofollow noreferrer">Struts2 CDI plugin</a>?</p> <p><strong>Update:</strong> The problem is that the container is not creating the Struts objects, Struts is, so the container doesn't get the opportunity to inject anything. You'll have to use the mentioned <a href="http://www.mailinglistarchive.com/html/dev@struts.apache.org/2009-12/msg00024.html" rel="nofollow noreferrer">plugin for CDI</a> to enable injection in your actions.</p> <p>If you want to give it a try, get Struts 2 sources:</p> <pre><code>svn co http://svn.apache.org/repos/asf/struts/struts2/trunk/ struts2 </code></pre> <p>Then <code>cd</code> into the <code>struts2</code> directory and run the following command (this will compile the required modules for the <code>struts-cdi-plugin</code>)</p> <pre><code>mvn install -pl plugins -am </code></pre> <p>Then get the sources of the cdi-plugin:</p> <pre><code>svn co https://svn.apache.org/repos/asf/struts/sandbox/trunk/struts2-cdi-plugin/ </code></pre> <p>And compile it:</p> <pre><code>mvn install </code></pre> <p>Now, with the following dependencies in my pom.xml:</p> <pre><code>&lt;dependency&gt; &lt;groupId&gt;org.apache.struts&lt;/groupId&gt; &lt;artifactId&gt;struts2-core&lt;/artifactId&gt; &lt;version&gt;2.2.0-SNAPSHOT&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.apache.struts&lt;/groupId&gt; &lt;artifactId&gt;struts2-cdi-plugin&lt;/artifactId&gt; &lt;version&gt;2.2.0-SNAPSHOT&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;javassist&lt;/groupId&gt; &lt;artifactId&gt;javassist&lt;/artifactId&gt; &lt;version&gt;3.8.0.GA&lt;/version&gt; &lt;/dependency&gt; </code></pre> <p>I was able to get an EJB injected in an Action:</p> <pre><code>public class HelloWorld extends ActionSupport { @Inject HelloEJB helloEjb; @Override public String execute() throws Exception { setMessage(helloEjb.getMessage()); return SUCCESS; } private String message; public void setMessage(String message) { this.message = message; } public String getMessage() { return message; } } </code></pre> <p>See <a href="https://svn.apache.org/repos/asf/struts/sandbox/trunk/struts2-cdi-example/" rel="nofollow noreferrer">https://svn.apache.org/repos/asf/struts/sandbox/trunk/struts2-cdi-example/</a> for an example.</p>

    2. COThanks for the explanation. This neatly explains why my listener (instantiated by the container from a web.xml entry) worked but my actions (instantiated by struts) did not. I just assumed that any annotated class would get processed via some sort of classloader voodoo. Is this sort of thing documented anywhere?

    3. CO@g051051 The listener is a so called "managed" component and injection works (since Java EE 5, see http://java.sun.com/developer/technicalArticles/J2EE/intro_ee5/#injection for example). Java EE 6 goes beyond this limitation by making injection possible in any POJO using CDI (but you have to use CDI or CDI "aware" frameworks).

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).
