title: NoClassDefFoundError exception in Java (com.ingrian.security.nae.NAESessionInterface)
body: <p>I am getting the following exception but I am not exactly sure what am I missing in my project. I couldn't find any proper resource about it. I assumed it could be because of the JRE version. Previously I was using 1.8 and then I switched back to 1.6 but it didn't work. Could someone please help me out? Thanks.</p>
