<div class="jive-rendered-content"><p> I have got a simple war file which contains an EJB3 bean (testing against AS trunk). The bean looks like this:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code jive-java">@Stateless
<font color="navy"><b>public</b></font> <font color="navy"><b>class</b></font> SimpleSLSB <font color="navy"><b>extends</b></font> SimpleBase
<font color="navy">{</font>
...
</code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The SimpleBase class (from which this bean extends) looks like:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code jive-java"><font color="navy"><b>public</b></font> <font color="navy"><b>class</b></font> SimpleBase

   <font color="navy"><b>private</b></font> EJBContext ejbContext;
 
</code></pre><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>So this base class is just a POJO with @Resource injection for EJBContext. During deployment of this .war on AS trunk, the web application deployer incorrectly starts processing this SimpleBase class and throws this exception:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><pre class="jive-pre"><code class="jive-code">
