Okay. Can you please post the entire exception stacktrace? That&#39;ll give<br>
us an hint on what might be wrong. Also please post the exact contents<br>

&gt; Hi Jaikiran. No that didn&#39;t fix it. On the other hand, the library is<br>

&gt;     &gt; &gt; Dear devs,<br>
&gt;     &gt; &gt; I&#39;m testing .ear classloading with utility classes packaged in<br>
&gt;     &gt;     the Enterprise Archive.<br>
&gt;     &gt; &gt; The following case test fails, so I&#39;m wondering if it&#39;s my<br>
&gt;     &gt;     misundertanding or a bug:<br>
&gt;     &gt; &gt;<br>
&gt;     &gt; &gt; application.ear<br>
&gt;     &gt; &gt; |<br>
&gt;     &gt; &gt; |  Webapplication.war<br>
&gt;     &gt; &gt; |  Utility.jar<br>
&gt;     &gt; &gt; |<br>
&gt;     &gt; &gt; |  META-INF/MANIFEST.MF<br>
&gt;     &gt; &gt;<br>
&gt;     &gt; &gt; Manifest file contains the Java EE compliant dependency to the<br>
&gt;     &gt;     class Utility.jar<br>
&gt;     &gt; &gt; Class-Path: Utility.jar<br>
&gt;     &gt; &gt;<br>
&gt;     &gt; &gt; However, the Webapplication fails to load the classes from<br>
&gt;     &gt;     Utility.jar, which are instead correctly pickedup if I move them<br>
&gt;     &gt;     into the ear&#39;s lib folder.<br>
&gt;     &gt; &gt;<br>
&gt;     &gt; &gt; As side note - I&#39;ve tried also stating isolated deployments to<br>
&gt;     &gt;     false, in jboss-deployment-structure.xml (which should default)<br>
&gt;     &gt;     without success:<br>
&gt;     &gt; &gt; &lt;jboss-deployment-structure&gt;<br>
&gt;     &gt; &gt; &lt;ear-subdeployments-isolated&gt;false&lt;/ear-subdeployments-isolated&gt;<br>
&gt;     &gt; &gt; &lt;/jboss-deployment-structure&gt;<br>
&gt;     &gt; &gt;<br>
&gt;     &gt; &gt; Any suggestion?<br>
&gt;     &gt; &gt; Thanks a lot<br>
