NoClassDefFoundError: Could not initialize class
<p>I'm developing an Identity Provider using OpenSAML API.</p>

<p>I have created a java application to test OpenSAML API which was a success. </p>

<p>The problem is now I'm trying to use that java Application in Servlet using glassfish and I'm loosing my mind right now.</p>

<p>Hear me out:
before you can start using OpenSAML you have to call it's bootstrap to initiate it's components, one of those components is 
    org.apache.xml.security.Init </p>

<p>so i added xmlsec.jar into libraries but every time I run the WebApplication it keeps on getting an exception: </p>

<pre><code>"java.lang.NoClassDefFoundError: Could not initialize class org.apache.xml.security.Init"
</code></pre>

<p>the confusing part is if I remove the xmlsec.jar from libs, it still knows the </p>

<pre><code>import "org.apache.xml.security.Init" 
</code></pre>

<p>but when I delete that and try to rewrite the same: </p>

<pre><code>import "org.apache.xml.security.Init"
</code></pre>

<p>now it fails because now org.apache doesn't have xml.security in it.</p>

<p>any idea guys?</p>

<p>PS: I'm using these:
                   - NetBeans IDE
                   - Glassfish 4.1.1
                   - Java EE 7
                   - JDK 1.8</p>

<p>glassfish output:</p>
