&lt;p&gt;NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config
Error during rendering of html dialog 'xxx.xxx.xxx'&lt;/p&gt;
&lt;p&gt;On console log, I see on "request" column, it shows "/ivy/faces/instances/144.../RES_NOT _FOUND" &lt;/p&gt;
&lt;p&gt;And, stacktrace is bellow:&lt;/p&gt;
&lt;p&gt;java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config

...&lt;/p&gt;
&lt;p&gt;But the screen is rendered well on the browsers&lt;/p&gt;
&lt;p&gt;How can i solve it?

Maybe Ivy just initialize the sub object before using it in script steps only, while rendering the view, it doesn't.&lt;/p&gt;</description><dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">nghianguyen</dc:creator><pubDate>Mon, 24 Feb 2014 11:26:35 -0500</pubDate><guid>https://answers.axonivy.com/questions/535/noclassdeffounderror-always-show-on-console-log-ide#544</guid></item><item><title>Answer by roland</title><link>https://answers.axonivy.com/questions/535/noclassdeffounderror-always-show-on-console-log-ide/541</link><description>&lt;p&gt;Hi,&lt;/p&gt;
&lt;p&gt;I've got this problem while trying to use a object of a Attribute which is not initaliezed.&lt;/p&gt;
&lt;p&gt;for example use of an value request.person.surname&lt;/p&gt;
&lt;p&gt;in my case I needed to initialize the sub object in a script step.&lt;/p&gt;
&lt;p&gt;hope this helps&lt;/p&gt;</description><dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">roland</dc:creator><pubDate>Thu, 20 Feb 2014 13:25:49 -0500</pubDate><guid>https://answers.axonivy.com/questions/535/noclassdeffounderror-always-show-on-console-log-ide/541</guid></item><item><title>Comment by nghianguyen on nghianguyen's question</title><link>https://answers.axonivy.com/questions/535/noclassdeffounderror-always-show-on-console-log-ide#538</link><description>&lt;p&gt;I have updated the content about the stacktrace&lt;/p&gt;</description><dc:creator xmlns:dc="http://purl.org/dc/elements/1.1/">nghianguyen</dc:creator><pubDate>Thu, 20 Feb 2014 09:07:59 -0500</pubDate><guid>https://answers.axonivy.com/questions/535/noclassdeffounderror-always-show-on-console-log-ide#538</guid></item><item><title>Comment by Reto Weiss on nghianguyen's question</title><link>https://answers.axonivy.com/questions/535/noclassdeffounderror-always-show-on-console-log-ide#536</link><description>&lt;p&gt;Can you attach the full stacktrace of the exception so that we have more information to analyse the issue?&lt;/p&gt;
